Doctor Who/With Spoilers/WMG



Post theories pertaining to current/upcoming Doctor Who episodes here. They should probably stay here until, say, a year after airing?

All of this will be resolved in a star-studded 50th anniversary special/mini-series.
Please, it's SUCH a obvious place for it. And what place would it be better to have the answer of the question "Doctor Who" be then the 50th anniversary?

The Doctor's crib is gonna be important
Back in 'A Good Man Goes to War', we saw what is, presumably, the Doctor's own, personal crib, from back when he was a cute little Time Tot.

The crib has some Gallifreyan writing on it, which, presumably, represents the name of its owner - in this case, the Doctor (I dunno, do we have a Word of God on this?)

Now, what's the First Question again? 'Doctor Who?'

The "Fall of the Eleventh" is called that, and not something else, because there are several Doctors at Trenzalore so they need to be specific
Tying into the idea of the star-studded 50th anniversary, it is called the Fall of the Eleventh because other Doctors will be there, including the 12th (after 11 regenerates)
 * Not just that, but all companions introduced in the revived series will be there. Just to enhance the scope.

Trenzalore is located on Gallifrey.
Because where else would anybody know the answer to that question?
 * In The Library.

The First Question is not for the Doctor...
It's from the Doctor. He's going to ask the Question of someone else: his past is so shrouded in mystery that he doesn't fully know it himself, and that's why he's remained so anonymous for all these centuries. If you rewatch "The Wedding of River Song", there's no mention of exactly who is doing this asking and who is doing this answering. From what the question is, it's easy to assume that only the Doctor himself can answer it, but that's just an assumption.

We will never get the answer to the First Question.
"Silence will/must fall when the Question is asked." Moffat is telling us that if we ever learned who the Doctor is, the show would Jump the Shark and eventually be cancelled, becoming "silent."
 * Or it will be saved until the BBC decides to end the show, possibly resulting in a massive breakage of the fourth wall.

We already know the Answer to the Question.
It's 42, naturally. "“Question and the Answer are mutually exclusive. Knowledge of one logically precludes knowledge of the other. It is impossible that both can ever be known about the same Universe.”"


 * The question is already known in-universe. When they find out the answer the universe ends, and Silence falls.

The question is "Not gone yet?"

 * And its answer is "Obviously not."
 * Jossed

The Question has to do with River's grafitti.

 * According to The Doctor it's the oldest writing in the universe, it's not impossible that the first question was based on it.
 * Ancient Alien: Who is sweetie?
 * Jossed

The Question is "Where did everything come from?"
It's the question that everyone, including us in Real Life, have been desperately trying to answer, since the dawn of civilization. The Silence are trying to find it out. Why would trigger Total Event Collapse? Perhaps the Big Bang Two was the original Big Bang, and all reality is one big Stable Time Loop.
 * Jossed

The Question is "What is the Doctor's name?"

 * Almost. See above, it's essentially this reworded.

The Question does not concern the Doctor at all.
In Let's Kill Hitler the Tessalecta stated the Question has been unanswered since the beginning of time. Since the Doctor is only 909, this may rule him out of the Question.
 * Assuming he is 909. The Doctor's actual age has caused a fair amount of debate, with even Steven Moffat himself stating that he believes the Doctor long ago lost track of it and is just making figures up. As far as his connection with the Question goes, there's nothing concrete to suggest that the Doctor is directly connected to the Question other than the Silence wanting him dead...though that could be just that they've forseen him working against/defeating them and want him out of the way before they concentrate on their own goals.
 * Jossed

The Question is "How the Hell do we survive Rory Williams"
The Answer is "Don't mess with him"
 * Jossed

The Question is "Will you marry me?"
The episode's name is The Wedding of River Song. The Doctor talked to the Impossible Astronaut (who we now know to be River) before she killed him. This question is hidden in plain sight because it's been asked millions of times before, but this time counts more than any other.
 * Jossed

The Question is "Who can stop me?"
One of the preview clips for the Series 6 finale has Dorium telling the Doctor that The Question will be asked at the fall of the Eleventh. This likely refers to the Eleventh Doctor. Something will happen to the Doctor, making him regenerate into the Twelfth Doctor. However, possibly due to a companion death, the Twelfth Doctor will be ruthless against whoever is around, explaining why Dorium says that "no living creature can speak falsely or fail to answer". This will be the return of the Time Lord Victorious and the start of the Valeyard.
 * Jossed
 * How is that jossed?
 * Because the question is “Doctor Who?”
 * The troper who posted the theory here. I'd simply like to thank the guy who asked how it was jossed for defending it when broad strokes still has yet to prove it wrong.

The First Question... is "Doctor who?"
"Madame de Pompadour: Doctor... doctor who? It's more than just a secret, isn't it?"
 * That very question was asked back in Silver Nemesis (which also saw the Seventh Doctor wear a fez, oddly enough...). It wasn't answered, but it was hinted that the answer reached back to ancient times, and that there was something dark and terrible about it. Something about the Doctor not being what he claims to be.
 * As the classic Who fans will know, these kinds of ideas were floated back in the Seventh Doctor's era as part of the (never completed) Cartmel Masterplan, with the idea that the Doctor's true identity was a dangerous and powerful secret. Between Executive Meddling and the cancellation, the Masterplan never reached is completion except in the Virgin New Adventures novels; the ultimate reveal was that the Doctor was a reincarnation of a figure from the dawn of Time Lord history, a contemporary of Rassilon and the true power behind the ancient Gallifreyan throne.
 * It was asked a lot further back than "Silver Nemesis". Try "An Unearthly Child". It was first asked by Ian Chesterton.
 * From Moffat's "The Girl in the Fireplace":


 * Well, we do seem to be in the middle of a Moffat Masterplan...
 * While it definitely seems like a good possibility, the Doctor himself asked it in the episode. Even if the below theory of it taking more then just words is accurate, it seems odd to reveal the matter of the question, and have someone ask it within 10 minutes of each other.
 * So the answer is the Doctor's true name? No wonder he never tells anyone!
 * Except River, the daughter of the one who will brind the silence. And, of course, there's only one time the Doctor ever would or could tell anyone his name... why that would bring Silence I have no idea.
 * Confirmed!

The First Question will be answered by Amy.

 * In Day of the Moon, when she was kidnapped by the Silence and we see her inside the ship, one of them tells her "You will bring the Silence." So if the Silence will fall when the question is asked...
 * A Silent also told her that she would tell the Doctor "What he must never know". The Doctor may regret telling Amy in The Beast Below that she should never hide anything from him...

River will be there, on the Fields of Trenzalore.
That's when she learns his name, because he has to answer the Question.

The Answer will undo the Time-Lock, allowing Rassilon, the Skaro Degradations, The Horde of Travesties, et cetera, to escape into normal time.
There is a name. A name struck from the record of history, such that almost no-one in this universe can remember it... And what's in a name? If you had to keep the most terrible force in the whole of creation locked up safely away from everywhere and everywhen else, what would you use as the key? A name only an improbable few can remember.
 * Actually, there's some stuff supporting this. Remember when it was mentioned that the Doctor's name "burns in the stars of Medusa herself" (i.e. the Medusa Cascade)? And this is the very same cascade that it's mentioned that the Doctor sealed himself... sealed, if you take the comic book continuity as canon, with the explicit intention of ending the Time War.

The Answer is...
"Eleven: "...well, I don't know.""

There's a good reason why the Doctor never tells anyone what his name is -- even he doesn't know! It's been basically proven (both in canon and by Word of God that he doesn't really know how old he is -- in the classic series, he's been known to call himself over a thousand years old, but now he's in his nine hundreds. So, why/how would he really remember or know what his name is?
 * Because River told him it to gain his trust, and he visibly reacted. And why would someone forgetful bury his name from the Carrionites and the Sibyllines? He's stated to be in his 1100s as of "Closing Time" (but in "The Impossible Astronaut"), but that's neither here nor there.

The Answer is...
"(Unknown): Doctor who?
 * Doctor Pond. He changed his name when he married River.
 * Maybe taking the wife's name is Time Lord tradition. The Doctor referring to Rory as "Mister Pond" when he married Amy reflects this.
 * I noticed that River married the Doctor on the day she was made a Doctor. So I think either this is an Incredibly Lame Pun or "Doctor Song" is the answer to the question...
 * not answerable with words, but rather by the actions of the Doctor himself. Is he the healer? The warrior? His actions will decide that, not his words.
 * actually the Doctor's name. Who knows, Moffat might fake us out by using the obvious solution. Reverse psychology and all.
 * It's really his name, but he's been running from it all his life because off some Gallifreyen history thing. Maybe he's the reincarnation of Omega!
 * not going to be said because the Doctor will regenerate just before being asked. Knowing the Question is coming, and that the answer is what sort of person he is, he will voluntarily regenerate. Then the dialogue will go:

Twelfth Doctor: I really don't know yet. Am I ginger?"


 * Has a chance of being true. At the Fall of the Eleventh the question will be asked. Eleventh what? The Eleventh Doctor. Silence must fall. The Doctor must die. Nobody said anything about regeneration, did they?
 * going to be revealed in the 50th Anniversary Special. Whatever it is, whatever the circumstances, and especially if the above is true and he regenerates, this Question should definitely be answered in the 50th Anniversary Special, preferably with as many Doctors present as possible.
 * nonexistant, or at least ever-changing. Because he regenerates and changes.
 * The TARDIS 'admin' password - which the Doctor set as his name. He thinks the only time he could only share it with someone is if he finds someone he trust with full control over the TARDIS (read: a timelord/lady he comes to trust completely). When the answer is revealed on the Fields of Trenzalore, something uses it to blow up the TARDIS, leading to the cracks in time arc, the universe going boom, and silence falling.
 * This troper is surprised no one thought of this yet. A name could only have this much weight if it is the name of someone great or terrible, or both. A name the doctor is ashamed of, a name which the doctor regrets ever having. A name that all the universe would recognize immediately. A name that would not only encourage him to run from his own people, but necessitate it. The name of a true madman. Rassilon.
 * Apollo. Apollo is the god of healing and the chief god of the Oracle, while the Doctor has a name meaning "healer" and has travelled all across time, fitting the oracle part. At the same time, Apollo is a god of diseases, similar to how the Doctor leaves disaster among his wake. It's a good old Meaningful Name. Hey, the Master has one too: Koschei.
 * "Hartnell." It would be a pretty nice tribute to the man who started it all.

The Doctor's name is 42.
We always knew the answer. Now we know the Question. Just for heaven's sake don't answer the Question.

The Twelfth Doctor will answer the Question.
The Fall of the Eleventh, it could be the regeneration of the Eleventh Doctor. It has been widely theorized that the Tenth Doctor spent a regeneration on his hand, which would make the Twelfth Doctor the last. Who better to reveal his last remaining secret?

The Doctor will reveal the Answer because he's just plain given up on going on.
The experience that leads up to his final regeneration may be so unpleasant and tiring that, having finally had enough with everything ever, he will just drop everything he's been clinging onto and essentially go, "Fuck it. You want to know? You really want to fucking know? FINE."

The power of the Answer is a side effect of the Doctor's greatest malady...
Essentially being God. Through his actions, the Doctor has become the most important person ever to have lived. The one thing he holds sacrosanct above all others is his name, so it has become such on a universal level. When it is revealed, that's it. No more point in going on, for anyone or anything, even time and space themselves.

The Fields of Trenzalore are better known by another name by the locals.
They refer to it as Foreman's/Totter's/Forman's Yard, the junkyard at 76 Totter's Lane.
 * Then it clearly hasn't always had its power. The Doctor was asked the First Question there ten deaths ago.

There is no Answer, and asking the Question will kill off the Silence, not the Universe.
"Silence must fall when the Question is asked", right? What I figure is that it's a Self-Fulfilling Prophecy / Petard-Hoisting about the end of the Silence themselves. They'll all end up at Trenzalore to prevent the Doctor from getting there (which will backfire spectacularly, natch), someone will ask the Question, and whatever's in charge of Trenzalore that prevents you from speaking falsly or refusing to answer will have some kind of massive freakout when faced with a question that doesn't have an answer. Boom go the Silence, boom goes Eleven, hello Twelve.
 * This would possibly also be a Stable Time Loop, since the Silence may have named themselves after the prophecy's mention of silence falling, based upon the assumption that they would make silence fall when (and if) the Question is asked by killing the Doctor.

The Question's status as the First may have been the result of a particularly wibbly-wobbly Stable Time Loop
If the Question's immense power is derived from its status as the First... bear with me. When time broke down and the distress signal was sent, it was sent all across time... including the very beginning, when the very first sentient mind in the universe to be capable of understanding it, at the very beginning of its sentience, wouldn't have had a damn clue who the Doctor was. It's wibbly-wobbly because the universe hadn't contained that event yet when the Question's status became known and the Silence were formed and they tried to kill the Doctor with River Song. Of course, it's not really a time loop if the fact that it's the First Question isn't what makes it so dangerous.

The First Answer

 * It's so obvious. "No, just the Doctor."

The "Fall of the Eleventh" does not refer to the Eleventh doctor's regeneration.
Because that's just way too obvious. And too soon.
 * "Too soon" depends on how long Moffat keeps it hanging over our heads.

The question does not actually refer to his name, but that's how the Doctor will answer it anyways.
Just because he has to tell the truth doesn't mean he can't "misunderstand" the question...

The Answer to The Question of "Doctor who?" will be a meta-reveal that it was a show all along.

 * The Question is referred to as the oldest question in the Universe, hidden in plain sight. Doctor Who? Perhaps it would have been better stated that it was the oldest question in the Whoniverse. And The Doctor knows a secret that must never be told that ties in with that question. The Reveal will be that this is all just a television show, and that when The Doctor reveals that to the world, the world must, of course, end.

Jesus is the Answer.

 * Every time this troper sees a bumper sticker that says "Jesus is the answer" she wonders what the question is. Now we know.
 * Doctor Jesus... kinda has a ring to it.

The Answer is...

 * ...Doctor Horrible! Cue evil laugh, regeneration, and enter Neil Patrick Harris, the Twelfth Doctor.
 * Doctor Forman

What do you get if you multiply six by nine?" Because that would be awesome.
 * Jossed.

We'll never hear the Doctor's real name.
We know that his name is pronouncable by humans, and in a reasonably short amount of time, because River Song whispers it in his ear. The reason he doesn't tell other people is because, by extraordinary coincidence, his name sounds exactly like a string of English curse words. They simply can't air his name on TV, and the Doctor doesn't like to say because it sound's like he's just swearing for no reason at other people. "Companion: Doctor, what's your name?

Doctor: Fuckshitcunt.

(Beat)

Companion: Well, fuck you too! Jeez!"

"The Question" of Series 6 is...
"When will they come together?"
 * Jossed. As Dorium reveals in "The Wedding of River Song", the Question is "Doctor Who?"

The Doctor's real name is "Victorious"
Well actually the word that means 'victorious' in Galifryan, hence why he once said it was unpronouncable to humans.

When the question is asked on the fields of Trenzalore, etc.,

 * The Doctor will whisper the answer into River's ear in a manner deliberately paralleling River doing the same in SitL
 * The sound will cut out, music and dialogue. Silence will fall, and we won't hear the answer.

Fall of the Eleventh will take place somewhere in the Medusa Cascade

 * In Fires of Pompeii, Evelina claims the Doctor's name is "Hidden in the cascades of Medusa herself". This is where Trenzelore is located. Speaking of, unless my memory is faulty, the Question is slated to have been written in the stars. A quaint shout out to Five, if you ask me. When his episodes open, just look at how then show's title appears- written with and in stars.

Rory will die in series 6
In the Doctor Who Confidential at the end of The Impossible Astronaut, Stephan Moffat says something along the lines of "sometimes, people you love die." He was referring to the Doctor and Rory.
 * Again?
 * as of the Siren episode it has only been three to four times. Not to mention since the show keeps reminding us of his time as the Centaurion he is effectively double the Doctor's age. You would think the poor chap wants to out do the Doctor everything, including regenerations.
 * He will die then not be dead once or twice more to make us think he never will, and then he will. For real and permanently.
 * This is a definite possibility. He's already died before in Cold Blood, and in both The Curse Of The Black Spot and The Doctor's Wife (though he was quickly revived in the former and the latter was an illusion). Everyone is expecting him to not die now, which means that in the second half of Series 6 he might be quickly and suddenly killed off for good, with no reset of the universe to save him again.
 * Alternatively, he might just become the Doctor Who equivalent of Kenny.
 * It appeared it was going to happen in The Wedding of River Song, with The Silence even commenting on it, before Amy's Big Damn Heroes moment.

Rory is immortal
For a moment, Amy had godlike power thanks to the crack in her bedroom. Not only did she bring The Doctor back into existence, but she also unconsciously made Rory immortal a la Captain Jack. Amy didn't successfully resuscitate him, he just came back to life shortly after she tried. Neither the TARDIS or The Doctor seem to notice this time though, possibly due to how it happened.
 * Sort of related to this, Rory is supposed to be dead. After all, he was dead or dying before he was erased from existence. However, Amy is some sort of reality warper(possibly due to the crack) and she brought him back. Now, the universe keeps trying to right itself, hence the reason Rory keeps dying. Amy keeps warping reality to cancel this. Eventually, this will start having really bad effects on the universe and Amy will have to accept the loss and let Rory die for good in order to prevent the end of the world as we know it.
 * This could also explain why the TARDIS sensors can't figure out if Amy is pregnant or not. She is pregnant with Rory's child, but Rory is supposed to be dead, so the baby both does and doesn't exist.
 * You have no idea how pregnancy works, do you?

River Song kills Rory.
As stated before, the Doctor isn't a human and Rory is the best "man" River knows. However with Rory's track record, he'll just get better. "The Doctor: Good men don't need rules. Today is not the day to find out why I have so many."
 * I dunno about getting better, though I do have my suspicions about this. Recall the Doctor saying the following to Madame Kovarian:

If you look at it one way, he's pretty much telling Madame Kovarian that he does indeed have rules, therefore not making him the good man that's been hinted at since and Stone. Rory, who, so far this season, has been nothing if not playing the role of 'the good man' straight ever since the beginning of the season, and the only time his temper's really been tested was only at the end of Almost People.
 * Considering the opening was a speech to dear River about how her father was amazing and would never let her down and all that, and well, he is her father, a role that is often looked up to by a majority of girls, that theory's just gotten a lot more likely, at least in this troper's opinion.
 * Look at River's expression when she first realises its Rory in the prison at the begining of 'A Good Man Goes to War'. Its absolutely pained. This may be because he doesn't remember her- or maybe because the last time she saw him, she killed him.
 * I though it was because this will be the last time she'll meet a version of her father, who knows who she is.

One of Rory's ancestors was a Chameleon Arched Time Lord
His Time Lord genes are mostly dormant, but he is still able to come back from the dead, just not regenerate. This might also explain the little girl. If it is Amy's daughter, Rory is the father, and all the time she spent in the TARDIS in utero activated her Time Lord DNA.
 * Jossed by the very episode that establishes Chamelon Arches. They don't make the Time Lord DNA "dormant", they put EVERYTHING Time Lord into the fob watch. Also, providing the Little Girl is Amy and Rory's daughter, also Jossed. She was conceived while the TARDIS was in flight, and got tampered by Eye Patch Lady and that's how she got Time Lord DNA.

Rory's grandmother was Susan Foreman.
In similar way to the Master, Susan escaped from the Time War by using a Chameleon Arch to make herself human. She then ended up starting a family and eventually died of old age. But before she passed away, one of her children ended up marrying someone with the last name Williams and they had a kid named Rory.
 * I thought she married David.
 * Time Lords don't have the same ageing rate as humans. He could conceivably have died before the Time War reached her.

Rory has a weaker version of whatever is causing Miracle Day.
The plot for Torchwood: Miracle Day, is that all humans on the Earth become immortal; they should be dead, but they keep living. Its been speculated in show that some aliens have been experimenting to cause this- maybe Rory just happened to be one of the earlier test subjects, and it allows him to keep coming back to life.
 * Given what we know by episode 10 of that series, probably Jossed.

Rory is The Master.
In Let's Kill Hitler, Rory mentions hearing a knocking sound in his head. Amy dismisses it as Hitler, but it could just be the sound of the drums. Rory is The Master, returned to life somehow. This is why he always comes back to life, because he's a Time Lord. Being brought back the way he was, he now permanently remains the same after regenerating.


 * Supporting the theory wholeheartedly. I say that he regenerated after breaking out of the Time Lock, and Chameleon Arched himself to be a human again. Regenerated to a little kid. The Doctor may or may not know about this fact already, but if he does, he just doesn't want to reveal him, and set the Master free - he does not want to basically kill Rory while freeing the Master. Also - the fact that he married the Master's daughter? Ouch.

Rory is The Doctor.
Something about the regeneration process split him into two people. The Eleven we know will become the Valeyard, and Rory is actually Twelve.
 * "You are turning me into you!" Rory, The Girl Who Waited. The Doctor, master of both the Batman Gambit and the Indy Ploy. On occasion the Indy Gambit and the Batman Ploy as well. The Doctor hates himself, really hates himself. Look at what he is facing, either an inevitable death or becoming the Valeyard. He can escape his greatest possible fall by suicide by River. Though, at what cost? He even said himself, or that Doctor said, in his final hours "humanity always needs saving". He'll need an heir if he does decide to not stop his death.
 * Alternatively, River lied about Rory being her father at Demon's Run, but earlier in her life (as Mels) thought he was before later finding out the truth. She truly is the child of the TARDIS and was actually conceived by the vortex itself. Rory has been a chameleon-arched Eleventh Doctor from the start, albeit with some kind of disguise or perception filter to look different that even he doesn't know has on at all times, including the illusion of having been a child. Note that Rory wasn't seen when young Amelia first appeared... he didn't exist yet. At some point, the Doctor figures out that Rory isn't what he seems and deliberately creates a paradox by crossing his own time-line and in effect, comes back for young-Amy after all and into her life as Rory. He had to do this, else Rory and River both would have never existed and bad things would have happened to the universe, but at the same time another version of himself still exists that shouldn't... the one doomed to die at the lake. It's a cruel parallel to The Girl Who Waited, with one Doctor having to face certain death. By the end, Rory would have found his fob-watch (thanks to questions from the Doctor about how he was missing something his entire life) and turned back into the Doctor, but the other Doctor is still dead and Rory is gone forever.
 * Or maybe it wasn't a paradox that he had to fulfill, maybe Eleven (a later eleven) planned and did this deliberately. One day he realizes he has grown too emotionally distant and realizes too late (after doing something unforgivable) that he's become a monster. So when he regenerates, he turns himself human, goes back in time, and deliberately becomes his own companion to see what it's REALLY like for them to travel in the TARDIS with him and regain a little perspective. When Matt Smith leaves, Rory will regain his memories and continue the show as Twelve (or move right into Thirteen with a new actor).
 * Or just to make this even more complicated, all of the above is true, except Rory is the regeneration of the ganger Doctor, sending himself back in time to gain perspective on humanity so he will be better equipped to stop the original Doctor, who has become the Valeyard.
 * This would also be a pretty big stab to the heart for fans of Old Amy. The TARDIS supposedly can't keep two Amys on board at once, yet there have been two Doctors onboard this whole time. Imagine how that realization might affect both Rory and Eleven.
 * It's also possible that Rory might not be the Doctor himself, but a sort of shadow or echo that imprinted on him since he was a child due to the Tenth Doctor's regeneration, as said above. Think of what happened to Jackson Lake, but to a lesser extent.

Rory's immortality has already been explained.

 * Seriously, its all in his original show, Inspector Spacetime.

Rory Williams is Stormageddon, Dark Lord of All

 * Craig and Sophie get caught in some more wibbly-wobbly timey-wimey adventures, and the Doctor loses another baby in time. (Seriously, don't let the Doctor near your baby). It lands in Leadworth and grows up to be Rory.

Rory can only die when he believes Amy no longer needs him.

 * Amy's exposure to the Time Crack over many years has made her a low-level reality warper, as revealed in the Big Bang, where she willed the Doctor back into existence. Because of her love of Rory, even when he'd been removed from her memories and timeline, when the Doctor's enemies used her memories to create a trap, she pulled his soul out of oblivion and into an Auton body. The combination of the Time Crack's power, Amy's exposure to it, Rory's devotion to her and his spending two millenia dedicating his existence to her protection have made him into the ultimate guardian of Amy, so much so that he is unable to truly die so long as she lives and needs him. That is why the Silence told him that no matter what he goes through she would never come back for him when he confronted them in the aborted timeline - it wasn't mockery or a threat, they knew that he'd never let them past him to threaten Amy while he lived, and they can't kill him unless he believes his duty to Amy was over. They wanted him to doubt Amy, and by extension his guardianship of her, so they could get past him and get to the Doctor.

Rory is related to Ash.

 * That level of badassitude? Gotta be genetic.

The Dead(th) Doctor
== Real!Doctor wasn't actually sure the Teselecta!Doctor plan could work. It wasn't an example of The Doctor coming up with a perfect answer to his problem, but an example of The Doctor performing one final, desperate gambit. == The key is that The Doctor doesn't actually know why his death is a fixed point in time. All he knows is that the Silence went out of their way to force it to become one. Now, the reason a fixed point in time is immutable is because so many other events are so casually tied to the fixed!event that attempting to changed the fixed!event causes so many other things to change that the universe gives up in frustration. The fixed!event is the load-bearing block of a universal jenga puzzle. So why is The Doctor's death fixed in stone (and how would that affect his gambit?)

1) The future of the universe must unfold in a way that requires The Doctor to have absolutely no more influence on it whatsoever. If this were true, then the plan using Teselecta!Doctor simply wouldn't work. Teselecta!Doctor touching Married!River would not set time straight again, and Real!Doctor would've eventually had to shrug his shoulders, climb out of the Teselecta, and set things straight himself.

2) The future of the universe unfolds in a way that's dependent on the news of The Doctor's "real" death. Hence, it's not The Doctor's actions that create the fixed point, but actions of other people that create the fixed point. So it doesn't matter if The Doctor lives or dies, just that other people act as if that he did. That's why the Teselecta!Doctor plan worked.

3) The universe hates people that try to mess with it. The Doctor's death didn't start out as a fixed point in time, but the Silence had made it so. The universe remembered the original version of events, decided to flip off the Silence for telling it what to do, and sided with the Time Lord Victorious just this once.

The astronaut is Old!Amy
Somehow Old!Amy doesn't die in The Girl Who Waited but gets rescued (by the Silence?) and is really angry with the Doctor for lying to her about sustaining the paradox (of both Amys surviving), in order to get her to help Rory save Young!Amy.
 * Jossed.

The astronaut is not River Song
In The Impossible Astronaunt, River seems just as surprised as everyone else is that the Doctor is dead, and when he returns, she doesn't see it coming at all, even though she supposedly was the one who killed him. Also consider the fact that she seemed pretty clueless as to who the little girl was, and we can deduce that River has completely forgotten being the little girl, or is not the little girl. We never saw the little girl regenerate into Mels, we only saw the beginning of her regeneration. I think Moffat's messing with us.
 * Why didn't Mels kill the Doctor in the cornfield? "We'd only just met." Mels had never met the Doctor before this, but the Doctor seemed to know who the astronaut was. If it was River, surely she would remember seeing and killing the Doctor when she was younger.
 * Jossed.

The astronaut/child is Jenny
When Mels/Melody meets the Doctor in the beginning of "Let's Kill Hitler!", she seems like she has never met him before. The young girl in "The Impossible Astronaut/Day of the Moon" did at least get a glimpse of the Doctor, and spoke on the phone with him. Even if it was River, and, at the time, she was too young to know it was the Doctor, you would think she would have "studied" the Doctor enough to at least retroactively realize who it was.

I don't think it was ever explicitly mentioned that the astronaut/child was River, but it was made pretty clear she was Timelord. If I remember correctly, at the end of "The Doctor's Daughter" Jenny is shown to start regenerating. Honestly, I'm surprised Jenny hasn't at least been mentioned here.
 * Jossed.

The Vashta Narada killed the Doctor
A space suit and River Song, and living in the Library they'd be able to figure out time travel and how to kill the Doctor.
 * Jossed.

The Doctor who died in The Impossible Astronaut is the Ganger version.
He really is the doctor, and yes he is dead. However, he's the Ganger Doctor and not the original Doctor. This might be the simplest answer as opposed to one involving multiple time lines or time travel or something.
 * Alternatively, the Doctor who died in the Impossible Astronaut was the 'original' Doctor, but since there's no fundamental difference between the Ganger and the Original, Doctor Two can take his place, allowing the show to continue.
 * There is a fundamental difference-Ganger Doctor will have a 200-year difference with the Doctor who dies.
 * Jossed. It's actually the Doctor operating a Teselecta of himself.

The Doctor who died in The Impossible Astronaut is not the Ganger version.
Because that would be too easy. It was the real Doctor. The original Doctor. The Ganger will replace him. Has anyone else noticed The Doctor's recent habit of being cloned, by the way? First Jenny, then 10.5, now Odo - I mean - the Ganger?
 * Ganger!Doctor is simply a Red Herring. By the previews for The Almost People, he seems to be at the very least psychotically unhinged and most likely will die in the same episode. The 'theory' that the future Doctor is his clone will probably be brought up between Amy and Rory to make the audience think it may be possible, but then he'll end up being killed. Also, Ganger!Doctor wouldn't probably be able to regenerate, whereas Future!Doctor seemed to be starting to before being killed.
 * Why would the Ganger!Doctor be unable to regenerate? The Gangers are exact duplicates of the original people, down to the very last detail. If the Gangers are identical to their originals, then there should be no physiological differences between them (excepting the cellular/DNA/whatever destabilisation). The Ganger!Doctor should therefore be able to regenerate to some degree. Due to the destabilisation the Gangers suffer, perhaps the process cannot be completed, but there does not seem to be a reason he couldn't at least /begin/ to regenerate (Ten pulled that trick off in Journey's End, remember?).
 * Also, wouldn't anybody be 'psychotically unhinged' if they realised that they weren't really who they thought they were, but just a copy? Since the preview scenes have been taken out of context, we don't know which Doctor is which or what happened to make either one act the way they did. We all know that the Doctor has a nasty habit of winding people up, and that almost certainly includes himself (all Nu-Who Doctors so far have suffered a huge amount of self-hatred). Er, anyway, point I was trying to make is that anything can happen and the Moff is obviously never going to stop screwing with us. (Long-winded comment got so long I had to cut it in two...)
 * Given some credence. The Ganger Doctor was deactivated, but otherwise was sticking pretty well together.
 * Confirmed. He's not a Ganger.

The Doctor who died in The Impossible Astronaut is a different Ganger version.
Amy and Rory tell him about being killed, and he uses the ganger machine to complete the stable time loop without being killed.
 * Jossed.

The Doctor will come back through a Ganger.
Prior to his death, the Doctor created a Ganger version of himself. Containing all his heart, mind and soul, it'll effectively be a Replacement Goldfish. Since Gangers are supposed to be indentical, the Ganger Doctor will be capable of regenerating. Indeed, since that clone never regenerated, he'll get 12 more lives.
 * Jossed. It was a ruse.

The Doctor that was killed is really the Teselecta robot.
It's not like the Doctor to leave a perfectly working transforming robot in the middle of Nazi Germany. We've seen that it can take the form of anyone it has data on, so why not the Doctor? At that moment it only seemed to respond to Amy commands, but I'm sure with a little Time Lord know how, he could adjust it so that it would take his appearance. I'm sure the Doctor would adjust it so that it's movements and interactions won't be as stiff. The Tesselecta is a perfect stand in to take a blow for the Doctor.
 * By extension, he could theoretically control it remotely with a ganger-harness or some such device.
 * Confirmed! Although he didn't pick it up in Germany. And he was inside, not controlling from afar.

It will be River's plan and not the Doctor's that saves him from his death in The Impossible Astronaut
To echo her saving him in LKH. everyone is expecting the Doctor to have some plan to save himself from death. Last season finale he had managed a last minute plan to set up Amy bringing him back from being erased, so we expect he should manage to change his own death.
 * After "The God Complex" he's starting to look like a Death Seeker. He seems to have resigned himself to dying for real and might even welcome it. It's probable that someone else is going to have to come up with and pull off a clever plan to save his butt this time around.
 * Jossed, sort of. It's complicated.

It was the real Doctor, but he isn't really dead.
A couple quotes: ""You cut off my hand...And now I know what sort of man I am. I'm lucky. 'Cause quite by chance, I'm still in the first fifteen hours of my regeneration cycle. Which means I've got just enough residual cellular energy to do this." (regrows hand) –Tenth Doctor, "The Christmas Invasion""

""Never shoot a girl while she's regenerating." (blasts Nazis with regeneration energy) -Melody Pond, "Let's Kill Hitler""

And, above all, Rule One: "The Doctor lies"

He's not going to die, obviously. Matt Smith has signed on for the next season. The question is, how is he going to get out of it? We learned way back in Christmas, 2005 that a regenerating Time Lord can heal injuries, and Melody/River kindly reminded us in "Let's Kill Hitler". The Astronaut waited until the Doctor started to regenerate before shooting again. It was implied that this was because that's when he was vulnerable, but what if it was the opposite? What if the Astronaut, whoever that is, didn't want him to die? He was shot again, but it had no effect. River said he was dead, but it was probably an earlier version of her in the suit, so she knew what was going on and lied to keep the continuity stable. The Doctor stayed quiet while they burned him alive because he's guilty and masochistic like that. Once they were all gone, he popped up gasping and swam to shore. He then lied, lied, lied to the entire Universe, made them all think the Doctor we know to be 11 had been the final regeneration. That's why he told Amy, Rory and River he was 1100 when we've seen him in trailers donning a cowboy had and telling the Tardis it was their last trip. The Doctor lied, River lied, and Stephen Moffat lied. Are you reallly surprised?
 * To the argument that the Tessalecta people said his death there was a fixed point in Space and Time: It's canon that Time Lords somehow see how fixed certain points in Time are. Presumably, these Justice Department blokes have a computer program, because they are certainly no Time Lords. No computer could rival the Doctor's own brain. I wouldn't be surprised if he planted that fact himself, so people would stop trying to kill him at other times.
 * Confirmed, at least in part. He faked his death, and used a Teselecta to do so.

The Doctor Killed The Doctor.

 * Either through a bizarre timeloop or something Ganger related, the Doctor was the astronaut as well, and the "death" was something quite different then what everyone else thinks it was.
 * Jossed.

The Doctor's death only became a fixed point in time after the Big Bang 2
When River Song tries to work out what point in his timeline the Doctor is in relation to her in Silence of the Library, one of the occasions she asks him if he remembers is the crash of the Byzantium. This happens in the Time of Angels, during which the Doctor is in his Eleventh incarnation - the same incarnation that River witnessed him die in. But when she asks his Tenth incarnation if he's gone through that adventure yet, she has to believe that the Doctor could be in an incarnation following his Eleventh, otherwise the question makes no sense - if he died in the same incarnation he witnessed the crash she's talking about, she'd know a different incarnation can't have witnessed it, and therefore the question is pointless (and potentially dangerous, given the views of herself and the Doctor on "spoilers"). Perhaps when the universe was destroyed and rebooted, someone or something took advantage of the re-creation to try and make some alterations to what normally couldn't be altered, such as changing the time and events that cause the Doctor to die. He can't have always been destined to die in his Eleventh incarnation, as we know from the events in the Sixth Doctor's trial that the Valeyard split off from him between his Twelth and Final incarnations. So perhaps the universal reboot allowed a new fixed point in time to be created. And maybe this is the Doctor's chance to survive. Protected by the Pandorica, he still counts as being from the original version of the universe, not the new version, so maybe he's not as bound by fixed points in time as is made out to be.

The Doctor used the Two Streams facility on himself to deliberately create a paradox, after seeing what happened to Amy.
The Doctor wasn't shown often during the episode, so it is possible that he had wandered off into his own personal stream for a while. He then found another stream from some time into the future and rescued his older self, who then took his place as the Doctor. Due to being a Time Lord and near the Vortex both versions of him could, for a while, be able to exist together. The present Doctor hid in the TARDIS away from Amy and Rory, and soon left for Lake Silencio after careful discussion and planning with his other self, while the future Doctor took over the Doctor's role. From The God Complex on, the Doctor we've seen is a paradoxical future-self that shouldn't be able to exist.

The present Doctor is the one to be shot by the astronaut, who is actually the future-Doctor about two hundred years older. Once he dies, the universe can't quite make up its mind whether his other self should be dead or alive. After everyone else was gone and the Doctor's body reduced to a mere skeleton, he recovers it and does much the same thing that River Song did to him in Berlin... he uses up his remaining regenerations, and indeed his entire life force, to revive the Doctor. He is completely absorbed into the 'real' Doctor, leaving no body behind, making them one once more with all the memories and experiences of both and ending the paradox.
 * Time goes wibbly, but it has nothing to do with Two Streams.

The Eleventh Doctor will be the last
If his future self's death The Impossible Astronaut was for real and won't be retconned, then there will never be a twelfth doctor. There is unlimited time for the series to continue, as the Doctor lives another two hundred years, but he will not regenerate again.
 * It turns out that he didn't die for real. Rule One in action.

Canton Everett Delaware III was lying.
Either the Doctor isn't dead, or he was a copy or a robot or something. But, for reasons yet unknown, the Doctor needed everybody to think he had died. But since this would be the last time Canton would see Amy, River, and Rory, there would be no way for them to discover this until the Doctor Revealed that he wasn't dead. Why do this? Who knows! The best theory this troper can imagine is that, for some reason, they needed to see the Doctor die so that Amy would try and kill the astronaut in an attempt to save him, for some reason I can't determine because we're only two episodes in as of this writing.
 * He was in fact a robot. Or something.

The Astronaut is some incarnation of Susan Foreman.
A bit out there, but the impossible astronaut can be thought of as unearthly, a call-back to An Unearthly Child.
 * Jossed. It's River. And NASA astronauts are from Earth, so what does that even mean?

It was River who...
killed The Doctor (or whoever it may actually have been) in "The Impossible Astronaut. Seems likely. She's Amy and Rory's daughter and after firing at the astronaut, she says, "Of course...". Seems like she knows why it didn't drop dead at the very least.
 * Confirmed. Sort of.

The Series 6 / Season 32 Midseason Cliffhanger will involve...
Her identity one of the mysteries that's going to be covered next series. The Cracks were slowly explained during series 5, why not dump reveal the mystery of the Silence at the midpoint, setting up the second half so the Doctor has to have separate adventures knowing what the Silence is, and that it probably has to be stopped immediately? With a redesign, since it could be in the budget this year. They're always involved when something big is happening, and when it's not them, it's... Okay, this is stretching it, due to The End of Time and everything, but maybe it's more specific Time Lords, like... Also not likely, but like I said, if it's not the Daleks, it's him. But maybe it's another Time Lord, like... It's about time she showed up again. What a cliffhanger it would be, too. Will the Doctor get to the fez? You have to wait until fall! BEST. CLIFFHANGER. EVER. Takes after her dad, no matter what he looks like and what silly things he thinks are cool. A new species called the Silents. This has been somewhat-partially proved in the trailer for this season, with that beastie that Amy turns her flashight on. I also found a script spoiler somewhere online with the line "Amy looks up at the ceiling. There are four Silents there." Finally, I found an interview somewhere with the producers saying that they were tired of the old monsters because of re-using them over and over, and wanted to introduce something new.
 * ...River.
 * CONFIRMED and CONFIRMED. She's part of the mystery of Amy's Schroedinger's Pregnancy.
 * ...the Silence.
 * ...the Mondas Cybermen.
 * Confirmed, but not a major redesign. The chestplate is just slightly different.
 * ...the Daleks.
 * Moffat has stated there will be no Daleks in series 6.
 * ...the Time Lords.
 * Jossed, though it turns out a plot revelation shows River/Melody is part-Time Lord, part-human, based on the mechanics of how the "real" Time Lords gained the ability to regenerate.
 * ...the Master.
 * ...Jenny.
 * Jossed.
 * ...a fez.
 * ...Jenny wearing a fez.
 * Assuming you mean the Doctor's daughter and not Vastra's associate, Jossed.
 * ... Susan. (but it will be her regeneration. This will solve any problems that may be caused by Carole Ann Ford's health. She's 70 years old, at least. I'm sure that may be a liability.)
 * Jossed, though Bernard Cribbins was hardly a liability and he was well into his seventies at the time of "Voyage of the Damned".
 * ...a new species.
 * Due to the Silence's nature (who appeared earlier in the premiere "The Impossible Astronaut"/"Day of the Moon"), this isn't COMPLETELY disproven, however they do not appear, nor are mentioned. The ceiling spoiler is from "Day of the Moon", not the mid-season cliffhanger episode, "A Good Man Goes to War". One could argue that the "a new species" bit is disproven, as the Silence are very strongly suggested to have caused the Cracks in Time, and one of them said "Silence will fall".
 * It's since been revealed that The Silence is a religious movement, not a species.

The person behind the Silence is.......
RIVER SONG!!!! Now I can imagine what most of you are thinking about that theory. And yes, I am totally aware of how ridiculous that idea is, and also why it can't work, so there no need to review those details. The reason behind this theory is that we know that River has done something really awful in the future...er the past.......FNARG, And she said at the end of The Big Bang that everything would change. We also know that both the mystery voice and River's true identity are something of a puzzle. Who's to say they can't be the same puzzle? As for the logic behind trying to kill your past self, well if I'm right, I'll just leave it to the Grand Moff to explain, because even I admit that this one is far fetched, and I can't work out the mechanics behind it. Just consider that we've seen the rules broken before, and consider that the answers to both of these mysteries will likely be something completely out of left field.
 * Maybe she did it so that the Doctor's actions would lead to a tiny change in the timeline, in which she doesn't end up imprisoned forever?
 * And you just changed this crack theory into something viable. Whoa!!
 * Is it worth noting that the episode that introduced River Song was called 'Silence in the Library?'
 * Jossed, as of "Closing Time". The Silence were the ones that caused River to kill the good man. Also, "A Good Man Goes to War" has wrapped up her identity.

The Silence are really...
The victims of the cracks in time. Now bare with me for a second. The cracks erased people from time and from memories. What happens when you look away from a Silent? They're erased from your memories. Because of the reboot that the Doctor performed on the universe, they aren't the full person who was eaten any more, more like an echo of them, and that is why they look the way they do. It also explains the fact that they are not a species-- multiple species were eaten by the cracks in time, but because of the way the "echos" were created, they all ended up looking the same. It also explains why they've technically been around forever-- the cracks completely erased you from time, so they could be in every time logically. It would also explain why Amy seemed to notice the Silent before anyone else and semi-remember them when no one else could-- she grew up next to the crack, which made it easier for her to remember people once they were eaten while others couldn't. The same principle could apply here.

The 11th or 12th Doctor will, at the end of his life, be granted more regenerations.
By his former selves. The reason for the call backs to the previous Doctors is because they'll all help, if only off screen for some, create a device to give him more regenerations. Perhaps the Master will try to use it and 9, 10, 11 and maybe 12 (and previous ones, if they can get them) will work together to stop perhaps the Simm Master and a new one. As for how Rose won't be with 9, it could take place after he left but before he came back and picked her up. 10 could be between companions.
 * Jossed? In one episode of the Sarah Jane Adventures, the Doctor says he can change 507 times. Then again, he lies.
 * Probably jossed. Supposedly, if a Time Lord killed another Time Lord, they would get the dead Time Lord's regenerations. The Doctor killed a whole bunch of Time Lords and has their regenerations. Or, since the regeneration limit was artificial and enforced by Rassilion, with the Time Lords gone the limit on regenerations is nonexistent.
 * Also, supporting the 507 thing, we have to remember that the Time War led to huge changes in Time Lord society, to the point of literally reviving their King in the Mountain. It's quite possible that the increase in regenerations has to do with this. Either removing all limits to support the war effort, or artificially supercharging everyone's ability.

The Tenth Doctor thought he was going to regenerate into the Valeyard
The Tenth Doctor is clearly dreading his regeneration. When he can delay it no longer, he flips one last control on the TARDIS. When he regenerates into Eleven, the TARDIS is crashing into the earth. Coincidence? Accident? Or Ten's last attempt to save the world from himself? Of course, Ten was wrong in the end. Or was he..?
 * This is somewhat supported by the fact that, when Ten is agonizing over having to sacrifice himself to save Wilf, he starts shouting "I could do so much more!" One could argue that he's just upset, or he just means this particular incarnation, but it does seem odd that he's ignoring the fact that his next incarnation would (theoretically) be carrying on his work...
 * It looks as if Ten had reason to be scared of turning into the Valeyard. The Eleventh Doctor acts like the Valeyard/Dream Lord contained in a Stepford Smiler shell in "The Pandorica Opens". That last control that Ten flips before regenerating may have led to the TARDIS developing temporal energy-regulation controls such as the Friction Contrafibulator and Zigzag Plotter (unless of course either of those controls were already present before the TARDIS regenerated into its Series Five form).

Eleven is the Valeyard
See above, and consider also that the weird half-death regeneration-with-the-same-face might still have counted against the doctor's remaining regenerations, bumping him right up against that window of Valeyard-dom.
 * What about the Dreamlord?
 * The Doctor's evil side.

If the Doctor ever regenerates into a women, she will be a lesbian.
If you have been a male for nearly ten centuries, this is quite a probable side-effect, considering. And if the Doctor had been in a relationship with a companion before regeneration (like the newer series likes to do these days), it could get very interesting...
 * If Moffat ever writes episodes for a female Doctor, he'll probably make her bisexual as a continuity nod to Eleven and the other bisexual Doctors.
 * Look up Curse of the Fatal Death some time. Written by Moffat but non-canonical. Less bisexual and more intrest in the Master, dalek bumps and all.
 * It's the Master. Being bisexual has nothing to do with it.

The Doctor has become the Valeyard
And no one can stop him.
 * Series Five seems to imply that Eleven is the Valeyard/Dream Lord trapped in a box (the Pandorica). The Series Five finale also indicates that whether or not the force trapped in that box is the Valeyard/Dream Lord, it is a force that cannot be stopped; it can only be tricked into submission. If that force is the Valeyard/Dream Lord, then Eleven has been tricking it into submission repeatedly across the series; his Big Bang idea was the smartest trick he used, but until the TARDIS explodes, the issue is still unresolved.

A Time Lord's sexual orientation can change with each regeneration.
Their default orientation is asexual-- possibly purposely engineered to keep the population down. For beings that can live hundreds of years, over-population could become a significant problem. However, every once in a while, after a regeneration they pop up as non-asexual. Ten is hetero, so is Eight, and we can presume One as well, since he had to get that granddaughter somehow. Eleven, I think, is gay-- he does seem to go on a bit about how good looking Jeff is. This explains, for instance, how Five traveled with so many attractive companions of both genders without a hint of temptation. Also, why Nine didn't show any romantic interest in Rose, but when he became Ten, he fell in love with her.
 * Nine is bi. He showed some interest in Rose, argued that he was not asexual, was pretty overjoyed at the 51st Century's pansexuality, and therefor Jack's pansexuality and there were other hints between him and Jack.
 * He didn't seem to like like Rose. I think he's probably gay.
 * I like this theory, but I think Eleven is bisexual at least. When Amy kissed him, his first instinct was to put one hand on her hip and the other in her hair.
 * The way Eleven checks out the rather hot young Venetian woman at the beginning of "Vampires of Venice" indicates that he has at least an appreciation for the other gender. I'm going with bi, personally.
 * I concur with Eleven being bisexual. Eleven's pained facial expressions in "Vincent and the Doctor" and "The Lodger" seem to indicate that he's also deeply entrenched in a Transparent Closet. Poor guy.
 * The Eighth Doctor Adventures and other EU stuff made the Eighth Doctor pretty definitely bisexual.
 * Clearly bisexuality is the default. Asexuality is a more cultural thing on Gallifrey.

The Dream-Lord is the Valeyard.

 * Not so much a wild-mass guess, as a logical assumption based on the information provided. Both are described as manifestations of the Doctor's dark side- the psychic coral merely acted as a conduit for the Valeyard to manifest himself prematurely from the stated point where the Doctor is meant to regenerate into him (between the 12th and 13th Doctor's- whom the 11th Doctor isn't that far off from). Notice how in The Ultimate Foe, the Valeyard manifests as a dark-haired and darkly-clothed man in contrast to the blonde, garishly dressed 6th Doctor, whereas in Amy's Choice he takes the form of a short, plump and plain man, in contrast to the 11th Doctor's tall, dark and handsome appearance, which he makes numerous mocking references to in the episode, amid his standard Hannibal Lectures.
 * I think it's more that the Dream-Lord is a manifestation of what becomes the Valeyard: not so much good-versus-evil, as a gradual degradation. Taking into account the events of "The Waters of Mars" -- or even going back to "School Reunion" -- it seems to me this has been a long time coming.

Regeneration doesn't have a hard limit, but a cultural/regulatory one.
There is a finite resource behind what allows/causes regeneration. A regen limit makes sense to avoid an eventual population nightmare if every time lord could liver forever, barring a double tap, no matter how low the birth rate is. Still, note that the Doctor now can regenerate ONLY 507 more times or whatever the number is. With no Time Lord Regeneration Regulatory Authority he either can freely use up his natural limit or that is all the regeneration phlebotinum the Doctor was able to salvage after the time war will allow for.

Eleven is becoming the Valeyard.
After the events of A Good Man Goes To War, Eleven has the Time Lord equivalent of a nervous breakdown and decides that in order to be 'good' again, he must fix history, starting with Earth. The first of the Autumn episodes happens to be entitled 'Let's Kill Hitler' (no, seriously). Assuming the first part of this WMG is right, the desperate Doctor attempts to 'fix' the worst event in human history: the Holocaust. Obviously, it doesn't work. Through his repeated attempts at 'fixing' history in various ways, he creates a universe in which all the crazy stuff rumoured to happen in A Good Man Goes To War (Roman Empire existing in the 21st Century, pterodactyls flying around and Winston Churchill riding a mammoth, for starters) actually happens. Realising that he has now just broken history possibly beyond repair, he falls deep into a state of despair and starts to call himself the Valeyard, believing that the alliance against him are actually right. 'Fixing' the Holocaust is the event the Doctor was referring to when he asked Rory about his time as the Lone Centurion, and holds great plot importance.
 * My god... the Doctor is responsible for the cracks. All in an attempt to change the universe enough, to fix the biggest mistake of all-The Time War.
 * OK, it's been mostly Jossed by Let's Kill Hitler. However, the new trailers and some new prequel-ly materials confirm that the crazy-alternate-universe stuff DOES happen. Whether the Doctor is the cause of it has not yet been revealed.

The Doctor's death will be used to get a fresh batch of regenerations.
How? Before he dies, the Doctor will plan a Xanatos Gambit to save his life. This will involve cloning a new Time Lord body, keeping it under tight wraps, and downloading all his knowledge and personality into it. Or just creating it as a vessel for his mind. This clone body will have never regenerated before, allowing the Doctor 13 more lives. The question is how to deal with the 24th Doctor, but that's not going to be until the 2060s.

The Ganger!Doctor is/will be the Valeyard.
A slightly unhinged version of the doctor, spawning from his eleventh form (making him a "twelfth" doctor), who, due to his presumably flawlessly copied time lord DNA can regenerate, and theoretically repair his own physical instability through the healing-y powers of that regeneration? Sounds reasonable to me.
 * Noob question; Who's the Valeyard?

The 13th and "Final" Doctor will be "The Perfect Doctor", a amalgamation of all of his previous incarnations. And Ginger.
The Doctor is basically a character who has a serial dissociative identity disorder- each regeneration brings a new personality (although with the raw essence of what makes the Doctor the Doctor always remaining). One of the main ways of treating multiple personalities, especially in Hollywood Psychology? Making all of the personalities merge into a single identity. So the 13th Doctor would be as if you had slammed the personalities and characters of all the other 12 Doctors together. Oh, and he'd be Ginger, because, well, it's a running gag.
 * His appearance and skills would reflect this too- Tom Baker's scarf, Sylvester McCoy's hat (although only after his companion told him to take off a fez), Davison's celery, Tennant's suits...

Alternatively, the 13th Doctor will be constantly switching between the 12 personalities.
i.e: He'll behave like 5 one second, then switch to 11, and start a sentence the way 4 would've, but finish the sentence the way 9 would.
 * It would be awesome, but we'd all have seizures.
 * 13 incarnations. 13 episodes per season.

The Doctor's final incarnation will be Flavor Flav!!!

 * Oh good gods no. Despite how much I don't want to hear it, please elaborate?
 * Possibly because of that ancient symbol of the might of the Time Lords, a giant clock medalion.

Susan will return for the Thirteenth Doctor's last story.
She will inherit the TARDIS. Whether she regenerates at the end or goes on for a season or two before regenerating will depend on Carol Ann Ford's health.

The series finale will be the twelfth or thirteenth doctor comatose and stuck in a human hospital.
Not damaged enough to regenerate, but too damaged for the humans to wake up. He'll be signed in as a John Doe (John Smith?) because none of his companions will be there to ID him and (metafictionally) so they won't be able to identify him. The companions will be running around trying to find him, figure out if he has a regeneration left and, if not, figure out how to get around the 12 regeneration limit.

The next series will depend on how soon the show is Un Cancelled. If it takes only a couple of years, or even a single season break, they will figure out how to revive him, and the Valeyard will be a result of messing about with his regenerations. If it's more than a couple of years, like when new Who fans are Running the Asylum and can have it revived, the series will pick up twenty years from the end of the current show's run with the companions' children and the same situation.

The Last Doctor will be a kid
Every regeneration of the doctor gets younger, so if were on the eleventh doctor, who is in his twenties, when we get to the last, it should be a teen or kid, and come on, how cool would it be to see a little kid with all the doctor's quirks?

10 or 10b will return in some form
We know how the River Song plot concludes on her end, and so eventually the eleventh Doctor is going to have to give her his screwdriver and do all that other stuff, leading to her heading to the library. There is just too much potential there not to show 10 again. Granted, David Tennant probably won't come back to guest star, so they'll have to use stock footage from the library episodes for those scenes.

Alternatively, Tennant will come back as a guest star to play 10b in an episode or two, now married to Rose and going permanently by the name "John Smith". John and the Eleventh Doctor will come into conflict in some way. In fact, he could be the episode's Big Bad. John may be embittered about no longer being the Doctor and the Doctor could be jealous that John was able to step off the roller coaster of being a galactic fixer and live a peaceful life. Eventually they would settle their differences, and once again go their separate ways.

The last story
The last story will involve the 13th Doctor (the ginger female one) discovering the true nature of his universe : a work of fiction. Thus, having discovered the final truth of the laws of nature in his reality, he will force the writers to come up with a good end.
 * So, sort-of Blade Runner then?
 * Hangonamo, ginger female one? We've had two ginger female companions lately, and this troper's felt for a while that there needs to be a definitive conclusion to Donna's story...

The Ginger Doctor.
We all know the doctor wants to be Ginger, but who would play him? My guess, Rupert Grint

The Ginger Doctor will be the Valeyard
Any concurrent Doctors, as well as, preceeding, succeeding Doctors will not be ginger. The good Doctors will be hilariously irate about this.

The final Doctor Who episode will have all 13 Doctors
Seriously final, will-never-be-renewed, we mean it this time seriously really truly last episode. Because it could never be topped.
 * And instead of calling it "The Thirteen Doctors", it will just be "The Doctor".
 * Gonna be pretty hard to pull off since William Hartnell, Patrick Troughton and John Pertwee are all dead.
 * Computer-generated people are getting better all the time, though.
 * And it's not like they've never recast a Doctor before (Richard Hurndall playing the First Doctor in the 20th Anniversary special).

The Doctors final regeneration will be Conan O'Brien
The ultimate crazy ginger.

The Thirteenth Doctor will regenerate into...

 * A young man who looks an awful lot like the First Doctor. Time isn't a big ball or a banana...it's a wheel.
 * Or a girl.

The Doctor will have a major arc for his 'last' regeneration.
Something that occurred to me was that the Doctor is starting to run low on regenerations and I could see several things done by companions if he dies without the 'last' one.

1) Either the doctor or his companions make an equivalent devils deal with a being of power or the master to get the Doctor another regeneration or another set of them. Done by the doctors companions to bring him back or the doctor to save the world/a companion.

2) Somehow the doctor gets tied to the Masters extra regenerations. In essence now if one kills the other they both are put at risk, maybe even being sympathetically injured if nearby. This would add a few interesting new potential elements for future shows.

The 12th Doctor will have been a companion
Well, masquerading as one. It'd be interesting, wouldn't it?
 * Mickey. Out of the four guy companions of the revival series (since it's doubtful the Doctor will regenerate into a girl), he's the only one that makes sense. If it turned out to be Rory, it would put massive amounts of Squick on his and River's relationship. Jack's a bit too fond of guns. And Adam... no, just no. Which leave good old Mickey.
 * Leaving aside the massive paradoxes this idea would cause, there's also Wilf.

The Real Amy was kidnapped before the start of the current series.
I would have theorised that she was kidnapped when the Silents grabbed her in the Day of the Moon, but she saw Eye-Patch Lady before that happened. Any way, far too obvious; we all know what The Moff is like when it comes to crazy-twisted, timey-wimey plot. Theories as to the exact time would be most appreciated. For now, I'm throwing out this one:
 * She was replaced while in the Pandorica. On one hand, Rory the Roman was being extremely badass and protecting her, but on the other... you can't remember them while you're not looking at them. The Silents have been on Earth since, like, forever. And two thousand years is a REALLY long time for the Silents to manage something like this. Not out of the realms of possibility.
 * They didn't need to take her from the Pandorica. Remember, they've been living together happily for quite some time by the first episode. Seeing how fast a clone can be made, it might be as simple as in-out in the night, while Rory's asleep, so he can't bust out his hand-gun (does he still have that if he's still Rory the Roman, Nestene copy?). She was probably flesh by the time the Doctor died, but any time they were separated in the meantime. Although a "long, long time" implies before his death.
 * Word of God is that she was switched before the start of The Impossible Astronaut, likely offscreen.
 * And later suspected as such, if not outright confirmed in "The Almost People".

The humans in The Rebel Flesh are also Gangers. The original crew are all long dead.
Something happened that wiped out the original crew, perhaps a very long time ago (the Doctor seems keen to point out that hours have passed when they think only minutes had, so something is clearly wrong). The entire state of the factory seems to be decrepit and in need of repairs, and there is absolutely nobody and nothing else on the island except them. They are caught in a cycle that began when the originals died... the Gangers for some reason don't remember what happened and then make a new batch of Gangers, until they die and those Gangers take their places and make a new batch of Gangers, etc... Each time that the 'originals' die, the memories of their Gangers are reset to the point where they first started working at the factory. They have been there for a long time but don't realize it, as this is the Flesh's way of keeping them alive (and sane). The Doctor showing up and the solar storm has changed everything though... it will end with both groups realizing that they are just as 'real' as each other and their deceased originals, and just how much time has passed as they are finally able to leave the island. Their families, as well as anyone they once knew, are also long gone.
 * This is just the kind of Aesop-inducing plot that the Doctor Who producers love to throw at us. Also, Rule of Drama demands that this happen somehow.
 * Jossed, Jennifer-Ganger attempts to use machinery designed to detect whether a human or non-human is trying to operate it.

The Amy in the TARDIS is a Ganger
The vision of the eyepatch lady are feedback to wherever the original Amy is. At some point during Impossible Astronaut/Day of the Moon Amy was taken by the Silence and duplicated. That's why the TARDIS reads her as experiencing Schrodinger's pregnancy - either the Flesh is having trouble duplicating a pregnancy or Ganger Amy isn't pregnant but the original is, and the TARDIS is picking up information from both when she scans Ganger Amy.
 * Confirmed. Whoever wrote this has earned the right to say "I Knew It!!"
 * Which raises the question: if the sonic can distinguish between a human and a replicant, why can't the TARDIS resolve her pregnancy as fake?
 * Because, presumably, the pregnancy isn't fake. It's both real and fake, with real!Amy and ganger!Amy. That's what the TARDIS is picking up on.
 * And there were hints that Ganger Doctor and Real Doctor were having some kind of feedback between each other, so the non-pregnant Ganger Amy was getting the pregnancy vibes through time (probably) from Real Amy, hence the confused TARDIS.

The Gangers are the origin of the Changelings
No noses, pale faces, born from (and reverting to) goop, able to switch between Ganger and human looks... Now they just need to get their own planet and cover the surface of it.

Rory is still not the original Rory.
He reacted the way he did during The Rebel Flesh because of his memories of being an Auton duplicate, and is starting to suspect that he still is. When the universe was restarted, Auton!Rory was somehow made human but over time he is regressing back to his original form. It was already happening when he impregnated Amy, which is why the Doctor's scan can't decide if she's pregnant or not. The original Rory died for good at the end of Cold Blood, and is still dead. The universe reboot was only able to bring back those who were erased while they were alive, which Rory wasn't, so his Auton double was made 'real' to compensate. The Rory we've seen considers himself to be as real and alive as his original, and sympathizes much with the Gangers because they feel the same way. Note that Amy doesn't think that the Gangers are real during an argument with him... when the truth comes out about Rory, she won't be able to take it.
 * Jossed, at least partially. The Almost People" and "A Good Man Goes to War" establishes that it was Amy being stored in a Ganger body is what caused the scan to go "pregnant/not pregnant/pregnant". I also don't recall Rory sympathising with the Gangers as a whole, only Jennifer.

There are two Amy Ponds. Or two universes/timelines, and Amy keeps alternating between them.
Amy's "stupid face" speech via the communicator can be taken to mean either the Doctor or Rory (although she says "I know you think it should be him [that I love]", which Rory certainly does not think of the Doctor). It's both. There's one Amy who loves the Doctor and one who loves Rory. One Amy who is pregnant and one who is not. One Amy who was whimpering and terrified when we heard her through the communicator, and one who was confident and defiant in the face of the Silence when we saw her in their captivity.
 * This is a beautiful theory, and I'll tell you why: Reg Amy (Regular Amy) was drinking wine at the picnic, whereas Preg Amy (See what I did there?) wouldn't. I really hope this turns out to be true. Her child is in flux, schrodinger-style, oscillating between being real and not real.
 * Maybe that's why she told the Doctor she was pregnant so...urgently? It's his baby. Only that version of events is popping in and out of existence. The way she refers to needing to tell the Doctor doesn't sound like how you tell a friend you're pregnant. "There's something I need to tell him, but it's like things always get in the way." In fact, all the dialogue seems to have these subtle double meanings. When he asks why she told him first, she says "Why do you think?...I traveled with you for so long."
 * Or there are two timelines. One is where the Doctor got Amy pregnant. Another where Rory got Amy pregnant. The timeline where the Doctor is the father is the one where Rory never existed.
 * No, it's not the Doctor's baby, and even if Amy is oscillating between two timelines, it's not the reason why the pregnancy scanner's all haywire. It's because she's been operating a Ganger body, but the "real Amy" is inside a chamber on Demons Run slowly growing a baby.

Ganger!Doctor will return from his shoes that he gave the Doctor.
Remember that the Doctor lost his shoes to acid, and then swapped his new pair with his Ganger? At the end of The Almost People, he still had them on. Gangers are created complete with clothing, which means that the shoes the Doctor is wearing are Flesh and the last surviving part of Ganger!Doctor. The Doctor mentioned to his clone shortly before his death that it could be possible for him to come back, and one day he will fully re-form from those same pair of shoes (much like Meta-Crisis Ten grew from a hand) and be stabilized by the TARDIS.

Given that both Doctors are the same, it's not a far stretch that the original Doctor did / will die in The Impossible Astronaut, and that Moffat is completely honest in saying that the Doctor is dead. For an alternate, possible Mind Screw, one of the two will die but it will never be made clear to the audience as to which.

The Time Lords WILL return
In 'The Big Bang', the Doctor piloted the Pandorica into the exploding TARDIS. In doing so, he deleted himself and the TARDIS from exisance. And, in the Last Great Time War, The Doctor killed all the Time Lords(minus himself and the Master(So far)), and a majority of the Daleks with the Moment. But, if he never existed, he never could've used the Moment to do that. Hence, the Time Lords and Daleks are still in the Time Lock, duking it out in the Last Great Time War. Eventually, they will dissolve the Time Lock, and re-emerge into the universe. Cue a scared as hell Doctor.

Pregnancy Timeline Shenanigans
There's a three month gap between 6.01 and 6.02. Other than that, there's no particular reason to assume lengthy gaps of time between any of the episodes this series.So. five months. But Amy can't have been four months pregnant when she was taken - she'd be showing by then, wouldn't she? She certainly would have noticed.
 * Someone has Word of God that Amy was switched with ganger!Amy pre-The Impossible Astronaut. At the very start of that episode, Amy mentions that it's been two months since they last saw the Doctor, and I think it's fairly safe to say that she wasn't switched while they were still travelling together.
 * Not exactly. My wife didn't show until five or six months, due to a stress and a combination of other factors, (Not eating right, and she didn't even know she was pregnant for the first two months..) so I wouldn't bet on that.

The Little Girl is Rory, Amy and the TARDIS's daughter.
In 'Day of the Moon' we get a conversation discussing the effects of time travel on a developing fetus. It seems unlikely that Moffat, who loves his Chekhov's Gun would include that if it wouldn't have something to do with the reality of the little girl. Furthermore, in the "Doctor's Wife" we learn more about the TARDIS. We learn that she exists simultaneously in the present, past and future, which could explain why the Amy's fetus keeps disappear- its travelling within its own time stream. Also, while the glow of the little girl looked like regeneration, it also resembled the way Idris glowed in the Doctor's wife. Since TARDISes have very close bonds with their Time Lords, and often aid in regeneration, it could be that the little girl's powers are more related to that, rather than an actual regeneration.
 * Child of the TARDIS Confirmed.

The little girl is River Song is Lucy Saxon.

 * http://www.imdb.com/name/nm3041653/ Unless IMDb made a huge mistake, the little girl is in fact Lucy Saxon, who could plausibly also be River, if she's a Time Lady under a Chameleon Arch or something like that. See above WMGs about the man River killed being the Master, etc.
 * IMDb has now removed this entry...

The little girl of the most recent episodes is Jenny's (half-)sister.
We know these facts:
 * The Silence have been around since “wheel and fire.”
 * The First Doctor's first serial took them back to the start of the “fire” part.
 * Wait, what? They clearly know what fire and firemakers are in that episode already when the Doctor arrived.
 * Hypothesis: During this time, the Silence noticed the odd man, and kept watch of the Doctor throughout all his adventures, and therefore know the “power” of a Time Lord. Which is also why they were trying to build their own TARDIS.
 * Second Hypothesis: The Silence want to have a Time Lord under their control, but don't have the technology (yet, technically) to insta-clone him like what happened with Jenny.
 * Confirmed.
 * The girl appears to be Amy's daughter.
 * Confirmed.
 * Amy (almost randomly) decides to try “seducing” the Doctor the instant they get back to Earth, where there was likely a Silent in her bedroom.
 * Hypothesis the Third: The Silence reached the same conclusion about Amy that the Doctor did about the Crack in Space/Time and decided to get the power of the Crack and a Time Lord by hybridizing Amy and the Doctor.
 * Hypothesis IV: The girl is Amy and the Doctor's daughter.
 * Jossed.
 * The girl is dying, but can Regenerate. However, the Silence put her in a life support space suit.
 * Doctor-Donna would have died because the Human body isn't designed to have all the knowledge and “power” of a Time Lord.
 * Hypothesis E: A hybrid of Human and Time Lord is ultimately unstable and that's why the little girl is dying. Eventually, she may continue to die and Regenerate until the suit catches her again or she runs out of Regenerations.
 * Jossed. She seems fine after her first regeneration.
 * Hypothesis 0: I've gone off on a tangent, haven't I?

The little girl in the spacesuit is Jenny
At some point she was injured and regenerated into the body of a child. She doesn't recognize her father because of his recent regeneration.
 * Jossed. We see her birth in "The Almost People", while Jenny was "born" elsewhere and when.

On Amy's Kid
Alright, so the little girl in the spacesuit (the one that regenerated at the end of the episode) is Amy's kid. She was conceived on the TARDIS, and thus has soaked up Time-Lord powers like a little kid-shaped Shamwow. Amy (and maybe Rory) got stuck in the 1960s, and she gave birth to and raised the kid there- hence, the photographs. However, Amy had to leave, (or maybe died) and she was left in the orphanage. The Silence kidnapped her from the orphanage, planted their Silence babies there, and stuck her in the spacesuit. She escaped, and is now toddling around New York. That's why the TARDIS scanner registered Amy as both pregnant and not pregnant- there were two Amys at the time, one pregnant and one not. The question is how Amy got magically not pregnant in the two month time skip- did she forget giving birth to the child?
 * The girl has the Silence's ability to make people forget about her. It's not immediate like the Silence but over time knowledge of her fades away (the Doctor mentions this in Day of the Moon). By the end of the second episode of the series everyone on the TARDIS crew has forgotten about her and forgotten to save her. They make no mention of her after the space-suit examination scene and Amy forgets the photos she saw in the orphanage.
 * Actually, at the end of the episode, after they drop off River Song, the Doctor mentions that they should look for the little girl, or they could just go off to have a fun adventure instead, and then says that he picks adventure. Kind of a What the Hell, Hero moment, really. Amy does seem to have forgotten what she saw in the room, though.
 * In broad strokes, yes. She has a Time Head, she's Amy's daughter and she was raised in the 1960s. Amy was left behind in the 52nd century, though.

The Silence and the girl
The girl is the daughter of the master of the Silence. The Silence try to keep her safe, but they can't just throw her in a cell, they're afraid of their master. So they put her in a suit to protect her, giving her some freedom, able to walk around, able to talk to who she wants. Their master is a timelord, as shown by the girl regenerating. The girl is very strong physically, something that isn't normal among timelords, so the timelord must be a special timelord, probably Omega. The Silence are the eqivelent of "Timelord Daleks," timelords mutated gentically and with temperal energy, posibly for the time war.
 * Jossed. She's the daughter of someone very opposed to the Silence.

The little girl isn't a Time Lord at all.
Rather she was simply being born in a manner that mimics regeneration. The episode began 3 months after the previous, and the "regeneration" occured 6 months after that. Assuming the baby was conceived shortly beforehand, that means the regeneration happened 9 months after. The form we see is something else, a living potential due to the fact she's a Schrodinger baby at the moment, and the regeneration is into her true birth form, whatever that may be.
 * Jossed. It's legit regeneration.

The little Time Lord girl will regenerate into Amelia Pond
It doesn't have to be this regeneration. But the inevitable Timey-Wimey Ball would probably explain that picture.
 * Jossed. All of her regenerations are accounted for. Plus, she interacts with little Amelia for much of the 90s and all of the 2000s.

Aliens made them do it
The Silence are using their post-hypnotic suggestion abilities on the Doctor and Amy to make time-babies. Specifically, the Future!Doctor (who had been a very naughty Time Lord recently). This may have happened during the Silence "kidnap" of Amy, which, due to its consequences, resulted in the seeming defeat of the Silence. The TARDIS's inability to decide if Amy is pregnant or not could stem from the change in the timeline. Either that or....
 * Jossed. It's not the Doctor's.

Amy was pregnant and has already given birth
To the little Time Lady, during her travels with the Doctor's travels in the TARDIS, but none of them remember it, due to the Silence and their memory wiping-ness.
 * Jossed. She's pregnant, but piloting a Ganger body so it doesn't show.

The little girl will...
After regenerating the (not so little) girl, whoever she may be, will be the companion for Eleven's next season.

The Little Girl is a Time Lady.
...Oh wait. Never mind.
 * Half-right.

The little girl is the Doctor.
The writers seem to have quietly scrapped the idea that the Doctor only has a certain number of regenerations, and he is potentially immortal. However, the two could work together; after a Time Lord uses all their regenerations, or is killed in some way from which they cannot regenerate, they outright reincarnate, losing nearly all their memories and starting again as a child. That's why the Doctor wanted them to get rid of his body; he didn't want them to see what happened next, as he knew it wasn't time for them to know yet. The astronaut suit needed a child in it; it couldn't last with no-one inside it for too long, and was only built for a child, and for whatever reason, the Doctor had to give in. Rather than send an innocent child to that fate, he decided that he himself would have to do it, and arranged things accordingly. So, the new little girl Doctor was taken to the past as soon as she came into existance. She retains only a few images from her past life; one of these is of Amy Pond, who she believes is her mother. When that woman appeared in the orphanage, she said "she's dreaming again", or something along those lines, suggesting the little girl's dreams can be projected in that room. That's why the picture of Amy was there; the little girl was dreaming of being with her mother. However, the first time she saw Amy, Amy attempted to shoot her. Naturally, the little girl Doctor is scared and confused by this, so she runs away when Amy appears again. The Doctor himself may have a subconscious suspicion of who the girl is, which is why he doesn't go after her at the end; he's simply scared of facing up to his fate. Eventually, he will realise what he has to do.

The little girl is Amy and Rory's baby
Ergo, Rory is a Time Lord under the effects of the Chameleon Arch, after all, we know literally nothing about his background,and Amy says he "fell out of the sky" (even though she says she was being figurative). CA'd Time Lords apparently age and die normally without regeneration as seen in John Smith's Flash Forward, but his genes were still Time lord, making the Girl a hybrid, NOT to be confused with the Metacrisis Doctor who was only part human and not naturally conceived. It's also why The Doctor allows Rory to help with the TARDIS, he subconsciously realizes that Rory is a fellow Time Lord and is capable of using it.
 * Time Lords who have been changed with the Arch are humans for all intents and purposes, genetically as well. Also, they always carry the watch storing the original biodata.
 * Alternatively, its still Rory's child, but the Time Lord nature comes from genetic alterations produced by prolonged in-utero exposure to the energies of the Time Vortex.
 * The child got time-head?
 * And time body, from the looks of things.
 * Confirmed, though she's human with a bit of Time Lord DNA, rather than anything Chameleon Archy.

The little girl was in the spacesuit when the Doctor died...
And she somehow managed to absorb his regeneration energy. Most likely this means she regenerates into River, since it's easy to see the Doctor sacrificing his life for her.
 * Jossed. She regenerates into River BEFORE killing him.

The little girl is Amy's child...
She was pregnant during the picnic with Rory's Baby, and gave birth during the six month interlude between Ep1 and Ep2. The Silents got a hold of the Doctor's DNA during the picnic (or some other time) and tampered with her genetics, causing the baby to be born Time Lord for reasons unknown. Alternatively, (as they have a lesser TARDIS) the baby was born while she was kidnapped. However, the Doctor interfered with that timeline, hence his TARDIS can't tell wether she's pregnant or not: There are two Amy's running around while causality is trying to unbend itself: In the other timeline, Amy raised her child happily, but all the time-fuckery made that go away. This is why it was so important to mention to us that everyone wants to get a hold of a Time Lord's body and why they had to burn it: To establish this for later. I had a reason why no one remembers but then...I forgot.
 * Besides the fact that the interlude wasn't six months, but two, Jossed. The body of the Amy that appeared in Episodes 1 and 2 was a Ganger, and as far as we know, that was never pregnant, only the real Amy that was connected to it. By "The Almost People", this body was destroyed, and the real Amy begins giving birth on Demon's Run. THIS Amy's baby could well be the Little Girl, however.

The little Time Lord is...

 * A regenerated Susan.
 * An earlier incarnation of River Song.
 * [Recap/DoctorWhoS32E7AGoodManGoesToWar:confirmed.\]

The little Time Lord is Jenny
A little obvious, but it's about time they brought her back. Eventually, she did regenerate for real, into a little girl, and somehow found her way to Earth in 1969.

The Girl is an established Time Lord character.
So, the girl is a Time Lord. Well, that was unexpected. The Doctor, The Master, (likely) The Rani and every other Time Lord are dead. So, you wanna bring one back? Do it this way. I'd guess she's The Rani. It's not like she has enough of a backstory to make it impossible, so this could actually be from before she first appeared.
 * The girl is young River Song; River Song is a Time Lord.
 * Confirmed, though she wasn't established as a Time Lord before the fact.
 * She could be Susan or Jenny.

The Girl is not a time lord.
The doctor allows the little girl, in the astronaut's suit, to shoot him so that his regeneration process will start, allowing him to share the regeneration energy with her and save her life. He arranged the meeting and everything that happened to the detail; he was always planning to do this. The question now is, who would he be willing to sacrifice like that for?
 * Jossed. His death was a still point reworked as a fixed point. The Doctor never planned to go to Lake Silencio.

The Girl is Amy's, Rory's and the doctors.
Something that bothered most people about Daleks in Manhattan is the way that the time lord DNA got mixed with the dalek hybrids. He may have done it durring the mixing phase knowing the scenario was inevitable where it would be needed. However the way the episode is shown implies some Bizarre Alien Biology. Maybe through that his DNA somehow mixed in the fetus causing a human time lord hybrid that is capable of regenerating without changing their face. In the Jenny episode maybe it wasn't just purely the doctors DNA getting cloned but some human was thrown in too giving evidence that human time lord hybrids can regenerate without changing. I mean she did have the knowledge of war maybe other stuff was put in.
 * Jossed, though Time Lord DNA does form in a weird way.

Amy chose her daughter's name as a whimsical play on "River Song."
Because it's just the sort of thing Moffat would do.
 * And it looks like he one-upped me. She named her after an old friend... who, unbeknownst to Amy, was actually Melody Pond in the incarnation immediately preceding Alex Kingston's.

The TARDIS was destroyed solely so the Doctor would reboot reality and cause the time pregnancy.
Because...well, there doesn't seem to have been any other lasting effect, and the Silence's plan appears to be in full gear despite the Doctor supposedly having "foiled" them in Series 5. Perhaps the Silence picked the spot outside Amy's house, on 26/6/2010, so that the Doctor would arrive there and then after the reset to pick them up so sexy time could occur? This would also mean that they created (or helped to create) the Pandorica, which doesn't seem like too hard a task for them.

Crack theory: River is the sonic screwdriver

 * We already had the TARDIS embodied in a human form, so why not the sonic screwdriver?
 * The Moff said that we would realize we knew from the beginning who River is. In Forest of the Dead her consciousness was preserved in the future!screwdriver.
 * If he really means from the 'beginning', does that mean she can't be at all related to Rory or Amy, because we didn't know them yet when we first met her?
 * She killed "the best man she ever knew." The sonic screwdriver was the instrument used to kill ganger!Doctor, among other people, in The Almost People.
 * The "best man" is not the Ganger.

River Song...

 * ...is just someone that we have yet to meet properly. She isn't some character from the classic Who, she isn't Amy or Rory or Jenny or Rani or any of those other theoretical Rivers. She isn't going to kill The Doctor and she isn't a time lord. She's a companion, just like all the others were/are. She is new, and we just happen to be experiencing her character in the opposite direction than we're used to, as we're seeing her timeline in reverse. We won't ever know who she really is until the day that she first meets the Doctor, as a young girl, which will unfortunately probably mark the last time we ever see her. Maybe she is the Doctor's wife. Maybe she just happened to be the one perfect woman for the Doctor. Maybe it's more complicated than that. We'll just have to wait and see.
 * Partly confirmed, partly not. She IS part-Time Lord, and she's the daughter of Amy and Rory, which barring extenuating circumstances, means it's not them. Also, she technically first meets the Doctor as a baby while we still know relatively little about her, but that's grasping at straws, as River couldn't remember what she did when she was one month old.
 * ...is the daughter of someone who travelled as a companion with Jenny (as in Jenny-the-Doctor's-Daughter.)
 * Jossed. The parents are Amy Pond and Rory Williams, the Doctor's companions.

River-travelled-with-Jenny - Key Points My evidence for this is mainly circumstantial and comes from musing upon: 1) Observed strong similarites in the personalities of Jenny and River. 2) The behind-the-scenes story behind Jenny's continuing existance River-travelled-with-Jenny - More Details (1) Jenny, the Doctor's daughter (created from the Doctor's DNA using a progenation machine), is a character introduced to us in the Tennant-era episode titled 'The Doctor's Daughter'.) Since this episode occurs shortly before Silence in the Library, when we first meet Jenny, we have not yet met met River Song. Watching The Doctor's Daughter again now though, after getting to know River somewhat, I see so much of River Song in Jenny that it is just screaming at me there must be a connection. They both basically do the whole sassy, sexy, good-with-guns thing, which could be a coincidence (and Jenny seems somewhat more 'innocent', which is not surprising since she is only a few hours old) . But what is striking to me is that they play this character in ways which echo each other not just generally, but actually *very* closely, as if one of these gals had spent time with and learned from the other at some point, not just as if they are playing the same general type:
 * When River escapes the Stormcage by kissing the guard with hallucinogenic lipstick, this echoes the way Jenny frees herself from a cell by distracting the guard with a kiss and stealing his gun.
 * When Jenny wakes 'from the dead', scaring the wits out of the two guys preparing (what they thought was) her corpse for her funeral, she smiles broadly and drawls 'Hello Boys!', and that is River all over.
 * And they are of course both rather good with guns.

Not that Jenny could BE River, not after that kiss. But could there be some other connection? So what I am speculating is that perhaps, as Jenny was going around Saving planets, rescuing civilisations, defeating terrible creatures, and doing an outrageous amount of running, she became lonely. Then, echoing her father, perhaps she collected up a few strays of her own. So perhaps River was one of these, and Jenny influenced her strongly. Or, maybe River was the daughter of one of these companions, and River picked up mannerisms and attitudes from an already adult Jenny as River grew up. So, all of the above was my first strand of evidence. My second is again very circumstantial: (2) Why the continuing existence of Jenny? What has she done for us lately? Is she going to make another appearance in some way? Originally Jenny was going to stay dead at the end of The Doctor's Daughter, but someone suggested that she be kept alive. Now this was obviously someone who loved the character, and by extension loved the potentials for future marvellous adventures that her continuing existence could give rise to. And the person who made this suggestion .... just happened to be ...... Stephen Moffat!

(this is also how she knows his name), meaning that From a Certain Point of View he did teach her. Also, in the case of the former, the Doctor was shown to be giving Donna rudimentary flying lessons near the beginning of The Sontaran Strategem. "Dalek Supreme:"
 * ... is the death of the Doctor. (See below, next section)
 * ...is the daughter of Captain Jack Harkness.
 * Growing up with Jack, she heard many stories about the Doctor. She grew to idolize him and seek him out. Archeology? What's a better way to find a Time Lord than messing with ancient technology that could easily cause trouble? Her "murder" was a plan thought up between her and Jack to get the Angel. She "killed" him, he pretended to stay dead, she went to jail and was able to get to where she could deal with it.
 * Addendum: Her mother is Amy. Because we all know that if Amy and Jack met without The Doctor or Rory to step in it would end in some very crazy, very kinky, most likely Jack-killing (temporary, as always), sex.
 * Addendum to the addendum: She was conceived in the TARDIS on hers and Rory's wedding night, and so far as we can tell, there was no opportunity to have met Jack, not even if Miracle Day happened before the beginning of "The Impossible Astronaut" with the two.
 * ...is a fez in disguise.
 * ... or possibly a regenerated version of the fez she shot.
 * The universe was rebooted. The fez she shot and the museum it came from never existed.
 * ...is (or is somehow related to) Bad Wolf
 * Not too far off the mark. She was conceived in the TARDIS as it travelled through the time vortex.
 * ...is the Rani,
 * ...but doesn't know it.
 * There's a pocket watch out there with her name on it. The 'human' forms of the Time Lords seem to be counter to their normal personalities. John Smith was (at first) meek, dull, and not overly adventurous; Yana was compassionate, kind, and wanted to do good; River is reckless, kind, an archaeologist (a joke of a career for a Time Lord), remorseful about killing, willing to pay for her crimes, and probably loves Children and Christmas.
 * What's more, it is the Rani herself who changed and asked the Doctor to help her and hide her watch. The Doctor found her, broken and lone, another victim of the Time War, in River's form. He realizes what's happened and tells the Rani of who she could be. The Rani, wanting a better life and a second chance, becomes River. That's also where she knows the Doctor's real name from.
 * To do a crossover with "what are the Silence?" theories: the Silence got hold of her pocket watch (or whatever her chameleon arch object it), and from it they learned all kind of scientific and technological information that's far in advance of anything else in the universe, since the Rani was one of the foremost scientific minds. Their ability to make people forget? The ultimate perception filter. That control room in "The Lodger" and "The Impossible Astronaut"? Their attempts to build a TARDIS based on the Rani's memories and knowledge.
 * Jossed on the Chameleon Arch front. She's the human daughter of Amy and Rory, but with Time Lord DNA
 * ...on her last regeneration.
 * Somehow she was able to hide this from The Doctor (for a while), and supposedly being taught by him how to fly the TARDIS and read / write High Gallifreyan could be a fabrication as she would already know how to do so. Her recent appearance suggests that it's still somewhat early on in her personal timeline, as she's not yet a Professor. She is using The Doctor for something not yet revealed, but will either be foiled in her attempts or change her mind, and eventually be reformed.
 * Vastra suggests that she can regenerate, whether or not she's the girl from "The Impossible Astronaut". It's unknown if she's on her final regeneration as in "she can never regenerate", as on her death in "Forest of the Dead" she points out that even the Doctor (who still has at least three lives left at this point) wouldn't come back from using his mind to rescue 4022 saved.
 * Alternatively, as "Day of the Moon" implies, she's the girl, and used up all her regenerations trying to keep alive until she met the Doctor. And that's why she killed him.
 * Confirmed, but in a roundabout way. In the episode, "Let's Kill Hitler", River poisons the Doctor to within an inch of death, but Heel Face Turns at the last minute and uses up all of her remaining Regenerations to save his life. So, it's NOT her 13th Regeneration, but it is her last, since she gave up all her future ones.
 * ...is the Eleventh Doctor's first companion.
 * River Song is a companion that the Doctor hasn't had yet, who first appeared in an episode written by Steven Moffat, who will be taking over as executive producer in 2010, which David Tennant may or may not be appearing in. River says the Doctor is younger than she's ever seen him - implying that, when she knew the Doctor, it was in another, older regeneration. Perhaps, in an inversion of their meeting in series 4, the newly-regenerated Doctor casts about time and space for someone he knows and ends up with River?
 * The "picnic at Asgard" and "crash of the Byzantium" must be with the Tenth Doctor, or she wouldn't need to ask him about them. Of course, this doesn't necessarily mean the Eleventh Doctor won't also interact with her, but it can't be the first time they meet (from his perspective) after this episode.
 * C'mon, people, Song isn't surprised at all that the Doctor is in his 10th regeneration. She would immediately know that this isn't "her" Doctor if he looked like someone she saw die and regenerate. She only knew him as #10, although possibly centuries into this regeneration's future.
 * One way it could possibly work is if she knows him in at least three distinct regenerations (an "Asgard" regeneration, a "Byzantium" regeneration, and a "singing towers" regeneration), and has reason to believe he might have had more in the middle somewhere. And if the Doctor doesn't keep a photo album around (or at least doesn't keep it well-organized), so she doesn't immediately recognize Ten as being a pre-her regeneration. And if she doesn't actually see him until after he regenerates into Eleven.
 * On set pics from when they were filming the episode with River showed some kind of metal case with "Byzantium" on it. So the "Crash of the Byzantium" is the adventure they have when 11 meets her next.
 * If she is a companion, she must be a sporadic one. Their timelines are not contiguous. This doesn't apply to the other companions - they experience events in the same order that he does, which (for whatever reason) is not the case for River. They know this, hence their system of comparing diaries.
 * Maybe due to the Timey-Wimey Ball, she did originally meet him as the tenth doctor, but now she does as the 11th.
 * It's been confirmed River Song is returning in Matt Smith's first series by on set pics. It's not known though if it'll be her "First" meeting with the Doctor.
 * Status: Jossed.
 * ...is the Doctor's Final Companion.
 * The diary isn't just a record of River's various adventures with the Doctor, it's a record of his adventures with everyone. He told her all kinds of things he told none of the others - like his name - because he knew that when he died, none of his still-living selves from earlier in his personal timeline would have all the memories that he did. As to why she knows Ten, well, we still don't know everything he did in between seasons and specials.
 * She does claim that the reason she was imprisoned is that she killed the greatest man she has ever known. Sounds like the Doctor to me. And if she was his companion when she did the deed, that would indeed make her his "last" companion.
 * ...is Amy Pond.
 * Ok, it's crazy and won't be true but I briefly had this thought. So far my only evidence for this is the following:
 * We know that Amy has already changed her name once.
 * Their hair colour.
 * Who can't see Amy using hallucinogenic lipstick?
 * In "The Big Bang", River gives Amy her TARDIS book. Except it's blank. And given that the Stable Time Loop is one of Moffat's favorite plot devices...
 * Didn't the writing come back when Amy brought back the Doctor though? I believe he gave it back to River at the end of the episode too.
 * There's actually a decent amount of evidence for this one. Here's a list.
 * Denied by Moffat. The memories River revealed in "The Impossible Astronaut" pretty much disprove this, too.
 * Jossed in canon by "A Good Man Goes to War", too. She's Amy's daughter.
 * ...works for the Valeyard.
 * Note: if Eleven is the Valeyard, then this will probably become true.
 * ...is the Doctor's mother.
 * Ask anyone in Real Life whom goes through life by a nickname only and, nine times out of ten, they'll say the only people whom insist on calling them by their true name are parents.
 * Denied by Moffat.
 * Plus, River and the Doctor kiss. It's Jossed.
 * ...was a Gallifreyan bureaucrat who miraculously escaped the Time War before it became time-locked.
 * She was on the Gallifreyan population control board.
 * Plus River said that some one thought her how to fly the Tardis the some one? her husband.
 * Jossed. She's the human daughter of Amy and Rory with Time Lord DNA as a quirk of when she was conceived. She was born long after Gallifrey was Time Locked.
 * ...is the same person as River Tam.
 * She grew up, got rid of the insanity that plagued her, and somehow changed ethnicity when she travelled to our galaxy. She then fell in love with the Doctor because he reminded her of how crazy she was; she missed that.
 * ...has already had her travels with the Doctor, off-screen.
 * After Ten lost Donna in such a heartbreaking manner, he rushed off to grab a companion who he knew wouldn't get a unhappy ending... well, living in a gigantic library for eternal un-deadness... let's say he wasn't thinking straight. He spent the equivalent of a holiday seducing and loving River. Then he reached the end (thanks to River telling him) of their relationship; he then swore that he would never again put another human being through that. Enter "The Next Doctor," where he isn't a emotional wreck.
 * Not an emotional wreck? The Doctor specifically mentions near the end of that special that companions end up breaking his heart, and for the rest of his run he is pretty miserable. The end of Journey's End destroyed him like nothing had before, because he had to for all intents and purposes kill his best friend.
 * Jossed. Even by the Series 6 opener, Eleven''s only just starting to be romantic towards her.
 * ...is a former companion of the Master.
 * In The Time of Angels, she says that she learned how to fly the TARDIS from the best-- too bad the Doctor was busy that day. Assuming she wasn't just teasing him, then who did teach her? She was also apparently in prison, and that River was in prison for "killing a good man". So perhaps the Master taught her how to use the TARDIS, along with the awesomely smug attitude, and she first met the Doctor while traveling with the Master. Then, somewhere along the line, she killed the Master, landing her in prison.
 * That makes her Lucy Saxon.
 * Jossed on the Lucy Saxon front. Lucy and River died in two conflicting ways. Not to mention that Vivien Brook told Lucy that her backstory on Earth is clearly not faked, and that's how she figured old Harold Saxon was a fraud. Also, her first meeting was as a baby on "Demons Run", and the first she can remember was as a child when the Doctor crashed into her life, long before she could conceivably be incarcerated.
 * Rather than literally killing the Master, she would have "killed" everything he was if she was the one who threw the switch for his Chameleon Arch. What jury's going to buy "I didn't kill him, I just rewrote his entire genetic code and made him a different species" as a defense?
 * ...is descended from Donna Noble.
 * The metacrisis left an epigenetic imprint on Donna's DNA. A hundred generations later, the bloodlines reconverge on River Song - all her ancestors for the last 1500 years were descended from Donna in some way.
 * This explains why River Song was overawed when meeting Donna, why she can fly the Tardis (and do things that the Doctor would never do, like using the stabilisers and turning the noise off), and why she speaks Old High Gallifreyan. She implies in Time of the Angels that her relationship with the Doctor is not marriage, but something much more complicated.
 * You're implying that knowledge of the language and TARDIS piloting skills are encoded in Time Lord DNA? How does that even make sense?
 * Yeah, you're right, a species who's members can rewrite their entire DNA at will to cheat death and who with the aid of a piece of technology the size of a pocket watch can transform themselves into whole new species having language or piloting skills encoded into their DNA makes no sense at all.
 * It's the Imprimatur of Rassilon - the epigenetic imprint she inherited was a copy of the Doctor's bond with the TARDIS. This explains the line "I learnt from the best - pity you were busy that day". The TARDIS taught her to fly it.
 * Jossed. River's parents were born circa the late 1980s-early 1990s and were Amy Pond and Rory Williams, long before Donna had her memories wiped in 2009 as a metacrisis and her marriage to Shaun Temple in 2010. Though she DID learn how to pilot the TARDIS from the TARDIS.
 * ...is Donna Noble.
 * She lived out her life with Shaun before succumbing to old age, but still had enough regeneration energy from the metacrisis to somehow be able to regenerate one time. This restored her memories and repaired her brain but she does not have a mind at the DoctorDonna level (or a second heart), but still retains much of the Doctor's knowledge. Perhaps through disorientation or choice she ended up in the 51st century, possibly through a crack in time. After recognizing her new form (albeit younger than when she saw her in the Library), the new identity of River Song was born, making her name and existence a Stable Time Loop as she had met Future!River many years before.
 * Donna and the Doctor each considered the other to be her or his best friend more than anyone else, and knowing that River was going to have many adventures with and be very special to the Doctor, River decided to become who she is because of him. She knows full well how she is eventually going to die (and having the Tenth Doctor's memories, has seen it) but knows that, like many decades ago, the journey is more important than the destination and they'll be best friends again. The reason why she reacted the way she did over Donna in the Library was because it had been so long since she had seen that face that had once been her own that young, and because her own time was soon to be up. Seeing the Tenth Doctor again after so many years must have affected her deeply as well. She can also fly the TARDIS and read / write High Gallifreyan because of the Doctor's memories
 * The main reason River is adamant against giving out 'Spoilers' is because the Doctor does not know who she is during certain encounters, and eventually she plans on telling him when the time is right, possibly by whispering something Donna would say into his ear (Spaceman?) paralleling the events of Silence In The Library. Eventually, a part of her will also live on with the two 'children' she once had in the Library.
 * All of this seems to be very unlikely as Word of God has said that no RTD-era companions will be appearing again, meaning that if River secretly is someone she is probably a character who appeared before but wasn't given official companion status, someone introduced by Moffat in Series 5+, or a character from Old!Who.
 * Look at how prepared and willing Donna was to find the Doctor in Partners In Crime. She also said that even if it'd take a hundred years, she would find him. If something like this is possible, then she would stop at nothing to be with the Doctor again.
 * Another possible scenario is that due to Donna's unique situation, she gained multiple regenerations in addition to the Time Lord mind. After her first eventual death, she regenerated and became a complete Human / Time Lord hybrid (still with only one heart though), but at the permanent cost of all of her memories. The Doctor finds her and looks after her for a while, this being the first time from River's point of view that they meet (and the Doctor likely giving her the name of River Song in an example of a Stable Time Loop). Donna Temple-Noble is still, for all intents and purposes, dead, and the Doctor never tells River about who she used to be. River, meanwhile, has a mind well above and beyond any human and quickly adapts to a new life. Regardless if she has anymore regenerations or not, she eventually dies for good at the Library, and regeneration might not be a great choice in any circumstance since she's not a full Time Lord, and could a) still die or b) lose all of her memories again.
 * Jossed. She was born to Amy Pond on Demons Run.
 * ...is an Old Gallifreyan.
 * River Song knew how to pilot the Tardis better than every Time Lord we've seen, and appears to have a longstanding knowledge of the Doctor. We all assume that it's future Doctors (11-13+ ) but it could very well be past Doctors as well. The Doctor seems to be able to recognize regenerations as the same person, however, Old Gallifreyan regeneration was different. The best evidence for this is that River could write in the Old High Gallifreyan language, which the Doctor is implied to be barely able to read. There are two known Old Gallifreyans, both of which good possibilities, which would be Susan Foreman and Patience, the Doctor's wife.
 * Jossed. She was conceived after the Time Lock was closed, and she's mostly human.
 * ...is a con artist who only pretends to be close to the future Doctor.
 * She has assembled extensive knowledge of the Doctor, perhaps from publicly available sources like A Journal of Impossible Things and the Library, and now uses it to manipulate the Doctor to her advantage, pretending to be someone she knows in his future incarnations.
 * This leaves the opportunity open for a Stable Time loop in which River Song discovers a diary chronicling a human's adventures with The Doctor, uses it to manipulate him into (possibly among other things) taking her on marvelous adventures and teaching her about the Time Lords, over time Becoming the Mask and truly caring for The Doctor. After her Death in Silence in the Library, her diary is recovered, and finds its way into the hands of a young River Song, a researcher fascinated with time travel and the legends of the long dead Time Lords and that species' sole survivor.
 * Jossed. Her affections are legit.
 * ...is the TARDIS.
 * There's precedent in the expanded universe for people becoming TARDISes. How about the other way around? What if River is a fragment of the TARDIS, in human form?
 * She knows the Doctor extremely well
 * She can pilot the TARDIS way better than the Doctor
 * She knows Old High Gallifreyan
 * The TARDIS can home in on her with pinpoint accuracy from 12,000 years away--the Doctor landed two years off his destination after a simple jaunt to the moon.
 * She carries a TARDIS-shaped diary
 * The TARDIS is always referred to as "she".
 * There exists an Alex Kingston quote re: River Song's ridiculously awesome heels - "Matt [Smith]’s got them. He kept them, not for himself personally but they’re around because he wanted them to be on the set of the TARDIS for evermore." Matt KNOWS and kept the shoes there not only because they're faboosh, but so she can acquire them there once she gains human form.
 * It all fits, I tell you!
 * Sorry, But As In Logopolis, A TARDIS inside a TARDIS Causes a Regression and Gravity Bubble, so, The theory Doesn't work.
 * And the TARDIS putting itself inside itself as per Time Crash and Space and Time also seriously messes things up.
 * Actually, since River is in a different form, it could, much like how different regenerations can meet and have no problem, whereas if humans cross their timeline Bad Things Happen.
 * Sorry, no. The Fifth Doctor's TARDIS collided with the Tenth's and that still caused Bad Things to Happen.
 * "The Doctor's Wife" sets a precedence for the TARDIS inhabiting a human body. What's more, the TARDIS (which had already been established as knowing things that are going to happen) drops hints about a river.
 * Proves nothing. She was in earshot of River when she revealed herself.
 * River could also somehow be a Ganger of the TARDIS itself... River's form being what the TARDIS thinks she would look like as a human, albeit as a child who later grows up into the River we know and love.
 * Jossed. She's not a TARDIS ganger, she's the human (with a hint of the Temporal Schism) daughter of Amy and Rory.
 * ... Is Prisoner Zero
 * They are both prisoners, and prisoner zero was never killed by the giant eye thing. They both have the same delight in knowing things the doctor doesn't, and I think that they both mentioned the "pandorica". It's possible!
 * ...is the Doctor's next regeneration.
 * I'm honestly surprised no one else has said this.
 * Just pointing this tidbit out:

"Some days are special. Some days are so, so blessed. Some days, nobody dies at all. Now and then, every once in a very long while, every day in a million days, when the wind stands fair, and the Doctor comes to call... everybody lives."
 * But as we've seen every companion pilot the TARDIS at some point during the revived series, this is definitely unlikely. It's most likely that The Alliance was manipulated to believe only The Doctor could pilot the TARDIS, so they would get him away from the TARDIS for whomever it was manipulating them to blow it up.
 * Or maybe all the companions had been erased from history.
 * Jossed. Jack is still in Torchwood, Sarah Jane appeared in a fourth series of The Sarah Jane Adventures (with Jo Grant as a guest) and Tegan, Ben, Polly, Ian, Barbara, Harry, the Brigadier, Liz and (implicitly) Ace are namechecked in the SJA episode Death of the Doctor, which is set after the universe reboot and Amy and Rory's wedding. We also witness River's birth in "A Good Man Goes to War". Also, all of River's regenerations are accounted for.
 * ...is her own person and the Doctor's next regeneration.
 * A precedent is established in Destiny of the Daleks and more subtly in The Caves of Androzani for Time Lords regenerating into a form that resembles somebody else.
 * You mean she's two different people, like Astra and Romana, and Maxil and the Doctor?
 * ... Is The Master
 * He found a way back from death, but it required becoming a human woman.
 * Jossed. She was born on Demon's Run.
 * ... Is still alive.
 * She regenerated when the Doctor had left-she was faking a death.
 * Unlikely. Otherwise how did her data ghost store her consciousness? And why was she so eager to take the Doctor's place if HE could regenerate?
 * ...a rejennyrated Jenny (see what I did there?).
 * It'd be weird and slightly Squicky but sure, why not?
 * She calls the Doctor "my love" in TBB. Squick to the power of squick.
 * I always thought she was saying that to the TARDIS.
 * Wouldn't that also be Les Yay?
 * Jossed. We witness both Jenny and River's births.
 * ... is Lucy Saxon.
 * Lucy traveled with the Master to the end of the universe. Given that the Doctor isn't too keen on crossing his own timeline (or probably running across the Master), River going to the end of the universe is probably not a future event. This theory has problems (Lucy being dead, for one) but may still somehow be possible.
 * Another problem is that the journalist Vivien Rook pointed out that Lucy has a solid background check, while Saxon's photoshopped history paper-thin was obvious to the people resistant to the Archangel network of satellites.
 * ... will come back from the dead in Series 6 / Season 32.
 * It seems like a perfect twist. The furthest point in her timeline we have seen so far was in 'The Forest Of The Dead' when she had sacrificed herself before the Doctor worked out a way to preserve her consciousness in soul although her body had died. Season 5 showed that people can be 'revived' even if they were written out of history, provided they are, in some sense, 'not quite dead' i.e. their soul still exists, in this case in the void, and they are actively 'remembered' by a time-sensitive mind like Amy's. It seems not so great a leap for someone to 'rewrite' reality sufficiently to put River back in a physical body. Amy is obviously a contender for the one who brings her back, whether or not intentionally; she being the one who brought back Rory, the Doctor, and her parents. Also Amy and River seem to have developed a close relationship and trust in the course of their few encounters together. Another option is that River is resurrected in a similar way by an enemy of the Doctor's. Or she may never come back in the physical world, but manage to cross over into dreams or other simulated realities. The least likely option to me is that she return as an android or cyborg containing her consciousness, although this would be useful if they needed to recast her for some reason.
 * Jossed.
 * ....Is Captain Jack Harkness.
 * Why? In the Big Bang she says "....that's when everything changes." Sounds familiar to anyone who's ever watched an episode of Torchwood. And doesn't halluciogenic lipstick sound like just the type of thing Jack would love?
 * Not to mention, if we go with the whole 'Jack is the Face of Boe' theory, in one of the first season episodes it's mentioned in passing that the Face of Boe has revealed he's prgenant. Either this was a lie, or Jack's biology has overgone a major re-write (besides the giant head thing, obviously).
 * Also, River's last words of "The Forest of the Dead" are:


 * When's the last time we heard those words? At the end of Captain Jack's first adventure with the Doctor, The Empty Child/The Doctor Dances. How better to commemorate your last adventure with the Doctor than the words that marked the end of your first?
 * Jossed. We see both River as a baby ("A Good Man Goes to War") and Jack as a little boy on the Boeshane Peninsula (Torchwood: "Adam").
 * ...will not appear in Series 6 / Season 32.
 * Simple deduction. She told The Doctor he would find out who she was soon, indicating that she will meet him for the first time while he is still in this body. However, she did not recognise Rory in The Pandorica Opens, so we can conclude that she had never met him before then. Since Amy and Rory are still with The Doctor, and companions don't tend to leave mid-series (and no, I'm not accepting Rory leaving and Amy staying as a possibility). Although of course, they could meet an older version of her...
 * Jossed. She appeared prominently in six episodes. She doesn't remember Rory for the same reasons Amy doesn't, and she isn't erased from history likewise. "The Wedding of River Song" implies that she lies about not knowing them in earlier appearances too.
 * ... Is a Gender Flip version of the Doctor.
 * Come on. She's just like him. Sure, you're thinking, "But she acts like she's his wife in his future!" Of course she does. Can't you see the Doctor taunting himself like this? It makes even more sense if she's doing it to try and keep him from finding out who she is.
 * While "The Almost People" clearly proves that the Doctor is in love with himself, Amy later gives birth to her later in the same episode.
 * ... Is Cameca.
 * The first woman we see the Doctor romantically involved with, despite the grumpiness of his first incarnation. To drive the point home, he actually got engaged to her. Clearly, she found some way to travel through time, eventually collected on his promise, and is now screwing with his later incarnations.
 * ... Is Marilyn Monroe.
 * River Song is always treating the Doctor as if he is her husband, and technically the Doctor is Marilyn Monroe's husband. They also both have curly hair. Marilyn Monroe went off with the Doctor and then later decided to stay in the future and build a career there, still having an occasional adventure with the Doctor.
 * ... actually Amy's biological mother
 * Amy's parents aren't her real parents; River traveled back in time and gave baby Amy up for adoption. It could explain how Amy's and River's personalities are so similar and the fact that the two deal with the Doctor and time travel.
 * Barring implications, Jossed. She's Amy's daughter.
 * ... Is from the parallel earth
 * The Doctor she first met was the one on Earth-2. It happened years later, after Rose had died and the Doctor there had aged into an old man. Note that when she first sees Ten she comments that he is "younger than I've ever seen you". She clearly isn't referring to physical age (Eleven looks younger, and she had met him by that point in her life). Well, maybe she isn't referring to "younger" in the absolute sense either; she met Ten before, but that was his half-human self who had aged. There was also a scripted scene (don't know if it was filmed or not) in Journey's End where the Doctor gives his clone a piece of the TARDIS so that he can grow his own. Maybe he did so, and had lots of adventures with Rose, who eventually died. The Doctor's next companion was River, but he was getting on in years, and knew that he would soon die (and not regenerate). So he trained River as his replacement; told her his real name, taught her to fly the TARDIS (he was better at it at that point), and eventually passed away. River found a way to break into our universe and hooked up with our Doctor.
 * Jossed. It's up in the air whether meeting River as a baby counts as "the first time", but that doesn't change the fact that she was born in N-Space on an asteroid called Demon's Run.
 * ... is a direct descendant of the royal family of Britain
 * mainly because Liz10 in "The Beast Below" acts in a similar manner. Awesome gunslinger, quite hot, knows a lot about the Doctor - because stories are passed down through the family...also, Liz10 probably gave the longest continuous confusion to the Doctor on the subject of her identity, second only to River. Admittedly, that's three minutes compared to years or possibly eons, but it's still a record.
 * ... is Queen Elizabeth I of England
 * Combing the previous WMG with the ever-present theory that River is the Doctors (future) wife. She killed him because she's still pissed about the whole "Virginia" thing.
 * ... is Idris
 * The fourth episode of Series 6 is named 'The Doctor's Wife', and has the character of Idris who is said to be 'an old acquaintance with a new face'. That comment is actually from our point of view, since canonically we've seen River before Idris. She will die and regenerate into River, which will be the beginning of their long journey from her perspective.
 * The same Idris who was the last King Of Libya?
 * Jossed, The Doctor's Wife is the TARDIS in a human body named Idris. Idris' body dies at the end of the episode.
 * ... is Madam de Pompadour
 * When Madam de Pompadour kissed the Doctor and/or when he read her mind/she read his mind, something happened to her. This might also explain why she knows his real name - she saw it when she was inside his mind. All of the mindreading the clockwork guys did might also have done something to her brain, making it more susceptible to the Doctor messing with it or something. Moffat wrote The Girl in the Fireplace, so maybe he planted that seed way back when?
 * Jossed. Madame de Pompadour and River Song have mutually exclusive points of death.
 * ...is Amy's Daughter.
 * In "The Impossible Astronaut" Amy says she's pregnant. Why River? Why not?
 * Seemingly implied is that she's the girl from Day Of The Moon, and has got a 'time head'.
 * A Good Man Goes To War confirms River is Amy's Daughter, Melody Pond. That's what her name translates to in the language of those living in the Gamma Forest.
 * ...is pregnant.
 * In "The Impossible Astronaut" both Amy and River are nauseous. We learn the cause of Amy's sickness, but River's isn't explained. Any theories on the identity of the theoretical father, besides the obvious?
 * No, it's noted in Day of the Moon that The Silence can cause this effect.
 * Random alternate theory: Little girl is River, and being in such close contact with herself from the past causes feelings of sickness.
 * Plausible. Let's Kill Hitler confirms she's the Little Girl.
 * ...is the Doctor's Gallifreyan wife from before the Time War.
 * She somehow survived the Time War, but her mind was broken after witnessing the destruction of her homeworld and the death of her entire species at the hands of her husband. To help her, the Doctor lets her use the chameleon arch to become a human with no memories of the Time War. What River perceives as her first meeting with the Doctor (when she was young and impressionable) and the moment when she first became so attached to him is actually moments after she was transformed from a Gallifreyan into River Song; the reason that the Doctor knew everything about her is because he helped to design her new memories and personality. But just like the Doctor began to emerge from John Smith in fits and starts, part of the Doctor's wife starts emerging from River, and she essentially falls in love with the Doctor as a result of already being in love with the Doctor. In turn, the Doctor recognises so much of his wife in River that he falls in love with her all over again. They fall into the dynamic of a married couple so easily because they're already married.
 * Jossed. She was born to human parents after the Doctor instigated the Time Lock, and has Time Lord DNA due to being conceived inside the Temporal Schism.
 * is Omega.
 * Think about it- we know Omega is in the new season. It's entirely possible that the end of the Time War screwed him and his timeline over so that he got born as a woman-or managed to squeeze his way out of that antimatter universe of his.
 * No we don't? When was Omega confirmed to be in series 6?
 * This might also be a good way to refer to the Cartmel Masterplan. Not only does s/he now have a crush on the doctor, he'll claim that he always had a crush on the doctor, even Back Then, when The Doctor was The Other.
 * ... is Ms. Frizzle
 * And she killed the doctor to steal his TARDIS so she could take her class on adventures. Sadly, shortly after this, she was caught and put in Stormcage.
 * Nope.
 * ... is the Silence.
 * She was first introduced by Silence in the Library. She was in the Tardis when it exploded in The Pandorica Opens. During Day of the Moon, Amy was told she would "bring the Silence". As of A Good Man Goes to War, we know River Song is Amy's daughter.
 * No, just a pawn of them.
 * ...is The Silence
 * "The Silence" being her Time Lord Title.
 * ...Is a Lying Liar Who Lies
 * She somehow has the ability to know exactly what needs to be said to get people to trust her - probably because she's so out of sync with everyone else, she can get the spoilers ahead of time and use them to give her the advantage.
 * She knew about Melody Pond's disappearance, and planned for it. She took the name River Song specifically because she could use it to later claim she was Melody. Everyone believed her, even the Silents, hence their insistence that Amy would "bring The Silence".
 * Pretty much confirmed.

The Doctor never told River his name

 * She just read it off his cot at the end of A Good Man Goes To War

The man River killed--the "best man [she] ever knew"--was or is...

 * ......the Doctor.
 * But don't worry - Time can be over-written.
 * Then why was Father Octavian so mistrustful of the Doctor, if he knows him as a hero?
 * Being a good man, and a hero, doesn't mean you aren't a complete madman either.
 * The question is, what reason did she kill him for? If there was a good reason why doesn't he forgive her and bust her out of stormhold prison? And if it was a bad reason why are the two on such good terms in the future?
 * She killed him because she didn't know him yet. She seems to have a bit of a shady past anyways, so it's not too far of a stretch to think that he was trying to stop her from doing something and she acted in what she thought was self-defense. If she flees the scene (or is arrested) before he regenerates, that would explain why she kept trying to play catch up with Ten when he first met her, even though (at least as far as we know) she never saw that incarnation of him again. She really only ever knew Eleven, and assumed that Ten was a later regeneration as opposed to a previous one...
 * it also ties in, very neatly, with her death. A Stable Time Loop where her last meeting with the Doctor (her death) is his first meeting with her. We then follow the Doctor's timeline of adventures with her, where each is one step backwards in her timeline until we reach her first meeting with the Doctor, where she kills him (so becoming his last meeting). The Grand Moff could not possibly pass up such an elegant time loop, with each end anchored by a characters death.
 * Not sure if this counts as wild but this seems the most obvious choice. It also syncs well with the above River is a companion of the Master theory. This is how Eleven will regenerate into Twelve.
 * Except she didn't kill this incarnation or a future one; she caused Eight to regenerate into Nine.
 * Why doesn't he remember?
 * The more think about it, the more I'm convinced that it's NOT the Doctor whom she kills. I mean, she was locked up for it, right? Well the Doctor is virtually a myth, a story to the people on earth and not even that (maybe even moreso now since the universe rewrote itself). He barely exists and he's certainly not considered as a human citizen (or an anything citizen for that matter.) How can you be locked up for killing a story?
 * I don't think so. In the Series 6 premiere, The Doctor dies. River then says to Amy and Rory that she is not afraid of the Doctor's death, as well as her own. There will be a worse day coming.
 * I assumed the "worse day" was the day she "looks into the Doctor's eyes, and he doesn't have a clue who she is."
 * In the Series 6 premiere River is the one in the spacesuit who kills the Doctor and an earlier version of herself gets sent to jail for the crime. The yonger River is shown the evidence of the crime so even though she has not killed the Doctor yet in her personal time line she still tells people that she killed the best man she's ever known because she knows she will kill the Doctor one day.
 * The River in the spacesuit is the younger version after she's done some research not long after the end of LKH. The one with Rory and Amy is a much later version (they sync'd diaries and was implied that to both of them, they've then done plenty of adventures together). When he tells Spacesuit!River to look over she asks how can she be there and the Doctor says "that's your future self" saying how she's serving prison time for the murder she's about to commit but won't personally remember doing.
 * Alternatively The Doctor that River kills is the Ganger! Version. While we do see that Ganger!Doctor melts into a puddle in the end of The Almost People, it doesn't mean that he didn't regenerate. It's quite possible that he survived the attack and also goes to the Battle of Demon's Run, albeit on The Slow Path and gets killed by River.
 * After the events of "A Good Man Goes to War", I think that that could've easily been the real Doctor, and that River Song is the one in the spacesuit.
 * 1) She was conditioned from birth to kill the Doctor.
 * 2) We have it on somewhat good word that that was "certainly" the Doctor, and he was "most certainly" dead. I don't think the Moff would cheat his way out of that one too simply.
 * 3) River is in Stormcage for killing "The best man she ever knew". Could be either the Doctor or Rory honestly but for the sake of the theory let's say it's definitely the Doctor.
 * 4) The Arc words "Time can be rewritten" are closely tied to River.
 * I'm thinking that Steven Moffat wouldn't stoop so low as to undo River's death (or sorta-death) from Silence in the Library, and the Arc Words seem more important than they did at first. I believe that younger!River killed the Doctor, but by the end of this series that event will somehow be worked out; the Doctor lives, and River doesn't have to go to prison for homicide (although she still might, in case it's needed to prevent a time paradox).
 * If she did kill the Doctor, it would have likely been before she truly knew him. Leading up to her becoming The Atoner, helped possibly by a regeneration.
 * CONFIRMED... kinda. It wasn't really the Doctor: he faked his own death in order to disappear from the public eye, and River knew this, but she took the rap anyway because the Doctor's "death" is a fixed point in time.


 * ... Captain Jack Harkness.
 * The Face of Boe, they called him.
 * Evidence:
 * It's implied the man River killed was well known in her own time. The only existing character who fits that bill, other than the Doctor, is Jack.
 * Two things almost always show up in the series finales: the Arc Words, and Captain Jack. We know we'll see River again "when the Pandorica opens," so it's quite likely River and Jack will be in the same episode.
 * What would happen if you fed a "fixed point" into a temporal eraser, anyway? If the Doctor could close the crack temporarily, maybe Jack could close it permanently.
 * The Rift was closed in Torchwood the Lost Files. Jack did not turn up in "The Pandorica Opens".
 * And Jossed.


 * ...a brand new character who will be introduced in the beginning of "The Pandorica Opens" and killed off in the end of the two-parter -- presumably in self-defense or desperation or after being possessed, because we can't have River Song actually being nasty or morally ambiguous.
 * (I'm sorry, but it irks me to see how many fans shout loudly that it's obviously the Doctor. They obviously haven't been baited by the writers long enough.)
 * Also, she'll turn herself in, just to make sure the audience will still like her...I mean, coincide with the timeline.
 * Jossed, at the start of Pandorica Opens, River Song's already in prison for the presumed murder.
 * ... Rory Williams.
 * Someone want to make an argument for me? I can't seem to put a coherent thought line together for this one.
 * River is Amy Pond, and Rory is certainly the "best man" she refers to and a hero to many.
 * With the reveal, the best man many girls know is their father - voila
 * Jossed.


 * ...her husband.
 * In order to save the Universe. Or something. River said The Doctor's "too complicated" to be married to her, although she didn't specifically deny it. Also, that comment about weddings, the "honey I'm home" could all be a very ironic game they're playing. The "everything changes" line could imply that the Doctor will never see himself in the same light again when he sees what people will do for him.
 * Confirmed, in a manner of speaking.
 * ...a "best man", as in a best man at a wedding.
 * All the "best man she ever knew" stuff was just her idea of humour.
 * Jossed.
 * ... herself, in a former regeneration, which also happens to be a future regeneration of the Doctor.
 * The Doctor - probably twelfth or later, as River considers both Ten and Eleven to be very young - goes into a situation in the full knowledge that he will not come out of it without having to regenerate. His companion, who has met River and knows about the "killed the greatest man she ever knew" thing but who does not know about regeneration, does not see the actual regeneration event. The companion jumps to conclusions when it's not the Doctor he or she knows who emerges from the wreckage but River. River!Doctor sticks with the story that she "killed" her former self to maintain the timeline (she knows that River Song spends quite some time imprisoned for murder) and because she feels some regret at having to end that particular incarnation when she did.
 * Implausible, all of River's regenerations are accounted for.
 *  is THE FEZ 
 * She later realized that Fezzez are cool and deeply regretted her mistake. She turned herself in to the authorities for murdering the greatest hat of all time.
 * The authorities of a Planet of Hats? I'm fairly certain you cannot legally murder a hat even in Whoniverse!Britain.
 * Incredibly unlikely. The Fez is from a universe where Stormcage doesn't exist. Plus, the museum probably doesn't exist in the rebooted universe in the state it was in.
 * Jossed.
 * is Jeff
 * Probable 'Best Man' at Amy and Rory's wedding, referred to as the Doctor's 'Best Man' at the conference, and hero to many for spreading the 000 virus. Of course, it's ironic because- (see Big Bad entry below)
 * Jossed.
 * Vincent van Gogh
 * She made it look like a suicide.
 * Jossed.
 * is Elan
 * He is the best man Haley ever met, maybe also the best man River ever meets, too?
 * Jossed.


 * ...JFK.
 * Jossed.

River learned to fly the TARDIS...
...from the TARDIS itself. Remember how she said she "learned from the best" and said how it wasn't the Doctor since he was busy doing other stuff? May have been achieved with some kind of telepathic connection, similar to the one Sexy had with Rory.
 * Confirmed in Let's Kill Hilter. The Doctor was indeed very busy.

River Song is the TARDIS
So, despite the heavy Doctor/River shipping that's been happening, Moffat randomly decides to throw in an episode where we see a much longer-lived relationship cast into the limelight? In an episode called The Doctor's Wife? When River has been heavily implied to be just that? It all makes sense now! At some point, the TARDIS comes to life again, as River! Perhaps it was even the Doctor meeting River in the first place that put the idea in her mind.
 * Jossed. She's not the TARDIS. Also, Gaiman had apparently been planning this episode since the time the Ninth/Tenth Doctor TARDIS room was still in use.

River Song gets a happy ending

 * River does get her consciousness saved into a computer by the end of Forest of the Dead, but at the end of the whole Matt Smith series, we'll cut back to River but now it'll show that the Doctor would have managed to save a copy of himself in that Sonic Screwdriver.

River Song's diary was or will be stolen from the Library.
The Doctor really shouldn't have just left it behind. All it would take for someone malicious is to sneak in there while the day of amnesty is still in effect (to not get eaten by the Vashta Nerada), and use the knowledge within to wreak havoc on the universe, especially against the Doctor. Time really will be rewritten, and not in a good way.

River Song is the first Time Lord.
Or at the very least the root of their society. Either by being the first ancestor of the people that would evolve into them, or by giving them the knowledge of the Time Vortex in the first place.
 * Jossed, though she did come into existence in a similar way the early Time Lords did.
 * Not necessarily. She's a time traveller. It's entirely possible that she could go back in time and become the first of the Time Lords.
 * Through the Time Lock? No...

There is an incarnation of River between Mels and the Astronaut.
At the end of Day of the Moon, we see the girl in the Astronaut suit start regenerating in 1969/1970 New York City. In Let's Kill Hilter, River says last time she regenerated, she ended up a toddler in the middle of New York. However, she is roughly the same age as Amy throughout their childhood, and Amy is not 40 years old. Certain sources say Amy was born in 1984, which means there is a gap of 14 years between known regenerations. The events of this gap will presumably explain who took care of River as a toddler and who brought her to England to grow up with her parents.
 * Jossed. River is the Astronaut, and we know there's no one between Mels and River. Therefore, any in-between incarnations would have to be between New York Suit Girl and Mels.

From now on, we'll see Nina Toussaint-White as Melody Pond / River Song.
We know that River/Melody's and the Doctor's timelines run in opposite directions. So, either one of these timelines (or maybe both) is already seriously screwed up somehow, or we'll see Nina Toussaint-White as Melody Pond from now on.
 * Their timelines don't actually run backwards; if they did, the diaries would be pretty useless.
 * Also, keep in mind that River expected the Tenth Doctor to know her and have a diary. The "present day" Eleventh Doctor hasn't been shown to be keeping a diary yet (although probably is as of "Let's Kill Hitler"). This can only mean River initially thought the Tenth Doctor was a later incarnation, so even she didn't take the "living backwards" thing entirely literally.

The "X is a Time Lord" meme on TV Tropes is soon to be replaced by "X is River Song".
The little Time Lady, Melody Pond and Mels have all been revealed to be past selves of River Song. If this happens to one more character, people will start seeing her everywhere.

An episode soon will involve the River of the Library.
Did anyone else catch the line in the episode with House? "The only water in the forest is the River" (Or something extremely close). Now, what have we seen about forests? A certain episode called Forest of the Dead, perhaps? Which just happened to have River Song's final resting place (If one can call it that) inside? Food for thought, at the very least...
 * probably Jossed given the meaning of that phrase.

The eyepatches let people remember the Silence

 * Not necessarily the eyepatch itself. If one wanted to remember the Silence, they would remove one of their eyes, hook it up to their brains wirelessly (or something), and keep it looking permanently at a Silent. You would be missing an eye, hence, eyepatch.
 * Confirmed.
 * Specifically, the eyepatches stimulate your memory functions so you remember them.

The Silents are the Echthroi
When they do their electrical attack, the victims are Xed (unNamed). This not only destroys them, it removes them from existence, like the Time Cracks. Which are ultimatly their doing also. At one point in A Wind in the Door the Echthroi are said to be causing rips in the universe. We never got any follow up on that destroyed secretary because she was removed from existance.

Amy is naturally, or was caused to become, a Namer. That is how she brought everything back. The Doctor, who has some qualities of a namer himself, tried to directly, but only subconciously kicked Amy's abilities into action when Rory died and was Cracked. "Tell me about Rory. Fantastic Rory, funny Rory, gorgeous Rory. Remember Rory." Which is how Rory's essence survived long enough to be actually Named.

Rory: Listen to me, you have to run. You have to get as far away from here as you can. I'm a thing. I'll kill you. Just go! Please, no, I don't want to go. Im Rory! I'm— Amy: Williams. Rory Williams from Leadworth. My boyfriend. How can I forget you?

In fact, at this point, Rory has been Named several times over. Rory Williams, Rory Pond, The Lone Centurion, Stupidface, Pretty...that's why he's so hard to kill.

The Silence Won't Fall...

 * The Silents will fall. We already know that there are going to be creatures in the upcoming series called 'Silents', afterall.
 * Jossed. Though technically a better translation is that silence "must" fall.

The Silents will be revealed to be Time Lords who were twisted refugees of the Time War, or The Silents were at least somehow involved in the conflict
I keep thinking of a (then) throwaway line from The End of Time, where Ten talks of the Skaro Degradations, The Nightmare Child, and the Could've-Been King and his Army of Never-Weres, and wonder if the Silents might fit in to that somewhere. The nature of none of those events or entities have been revealed heretofore, and we know that Steven Moffat loves binging on Continuity Porn, so the means, motive and opportunity for him to pull this twist is certainly out there. Since we don't know where the Time War fits into to time, linearlly, could they possibly be combatants from the war who somehow were able to evade the time lock and the destruction of both Skaro and Gallifrey? If that's the case, it might bring some sort of answer to, if not who killed The Doctor, at least WHY. Particularly if the Silents are twisted Time Lords. And remember, they did, apparently, build their own TARDIS-like-thingie...
 * Oh, and the mid-season cliffhanger is called A Good Man Goes to War. Mayhap a Time War?
 * It's not the Last Great Time War, and the battle is fought in one timezone (though it does involve beings spanning from the 19th to 41st centuries)
 * Alternatively, the Silents are a twisted new breed of Time Lords descended from River Song, making them a race of Time Lord-human hybrids. They eventually develop their own version of the TARDIS that is seen in the Lodger, but just as they aren't "pure" Time Lords (you can't just cook up a Time Lord like that, as a certain someone said), the technology they develop is also impure - the Doctor claims that he's "too much" for the Lodger-TARDIS, which indicates that their TARDIS isn't as powerful as a Time Lord's one. This could also explain why they were supposedly driving the human race to develop space-faring technology - their attempt at a TARDIS could travel in time, but not space, so while they could go back and exist since the wheel and the fire, they remained bound to a single world. On the other hand, they found a way to master the perception filter technology even more than the Time Lords ever managed, which is where their Forget-attribute comes from.

Schizophrenia is caused by the Silence in the Whoniverse
We don't really know what causes schizophrenia. All we know about it is that the symptoms include hallucinations, delusions, and, occasionally, catatonic stupor and that antipsychotics and certain other treatments seem to be somewhat effective in treating it. The most common hallucinations are audio - the hearing of noises (like voices) that aren't there. Who's to say the voices aren't the Silence, and the delusions aren't the Silence putting suggestions in the affected person's mind? In "Day of the Moon", it is revealed that the Silence can put someone to sleep merely by telling them to, even without leaving their sight. The catatonic stupors (loss of physical mobility for a set period of time) may also be caused by the Silence. As for why certain treatments seem to be effective, the Silence are smart. They could easily lay off a bit. Why would they do this? Seems like a fun prank for the adolescents to carry out.

The Silence and the Silents are two different things.
The Silents are an alien race that serve something called the Silence or are working towards an event called the Silence. Thus when they say Silence will fall, they are not referring to themselves, rather to their goals.
 * The Silence is a religious organisation. Probably confirmed.

The Silence really were in the Library.
And they, inadvertently or not, were responsible for filling it with so many Vashta Nerada.
 * Jossed in the story. The Vashta Nerada were not "filled". They were taken there when their spores were inside every book.

The Silents and the Ood are closely related

 * The Silents' faces look like silly putty somebody dragged their fingers through. It could be the precursor or descendants of the Ood tentacles.
 * The Ood were developing time travel technology when we last saw them, and somhow advancing way faster than they should. It was never explained. Perhaps they got as far as the Black TARDIS?
 * There is a scary Ood in the trailer for "The Doctor's Wife". Eyes glowing green this time, almost creepier than red.
 * The episode gives no connection to the Silence. The green-eyed Ood is possessed by a being from another universe.
 * The Silents' sits even look like they're made from the same sort of material as the Ood's outfits.
 * Fact is, no matter how much they were abused, the Ood are a scary looking people. And they have reason to be angry with humanity.
 * The Silents'/Silence's anger seems more focused on the Doctor.

The Silence help out humanity, such as protecting them from aliens when The Doctor is not around.
So, Silence Falling is referred to as a bad thing. The Silence have been controlling Earth since as long as there have been protohumans. We are still around, aren't we? They may protect us when there are problems when The Doctor isn't around. We just don't know how many times that they have saved us since we forget them. They may antagonize The Doctor because they are protective of us, we're their protectorates, not his!
 * Also, that might explain Amy's baby/not baby: If the Silents have been protecting Earth, then Earth will have been destroyed if they fall. In the original timeline, they are still ruling Earth, allowing Amy and Rory to live a normal life. In the new timeline that the Doctor made, aliens have destroyed and ravaged Earth, not allowing Amy and Rory to have children.
 * Her baby/not baby has nothing to do with alternative timelines. That's because Amy's occupying a Ganger body.

The Silence aren't evil and the Doctor is essentially committing genocide.

 * Think about it: we have only seen a Silent attack without provocation once, and as mentioned above, that may have been out of frustration. Furthermore, one person's action does not define a species. And controlling human history behind the scenes is not necessarily evil: if a new species appeared on your planet that forgot you existed when they looked away, wouldn't you want to help them out a bit? We don't know for certain that the Silence are responsible for the cracks in time. It's all Steve's fault, of course.
 * And even if they were behind the cracks,who's to say they didn't mean for it to reboot reality and create a better world.
 * I think it was made pretty clear that their intentions towards humanity are not good when one Silent told Canton that he should kill them all on sight.
 * And pretty much Jossed by the series' second half.

The Silence were not responsible for destroying the TARDIS and the universe. Rather, something much, much worse was and it is now free.
"Silence will fall" in fact refers to their downfall in Day of the Moon at the hands of the Doctor. Something terrible was being restrained and rendered powerless by them, which might have been one of the reasons they acted as they did... though they were silent, mostly-evil conquerers they were also in a sense protecting humanity and the rest of the universe (but most importantly, themselves). With their power and influence greatly diminished, whatever it was they were guarding has broken free. Destroying the universe and the TARDIS were just pieces of a great plan to get the Doctor to neutralize The Silence, which he ultimately did.
 * And that person they tried to stop...may just be the Doctor.
 * Jossed. "Silence will fall" has nothing to do with their downfall.

Between 1969 and 2011, The Silence did something to reverse or counter the hidden extermination order in the moon landing.
It is unlikely that Amy, Rory or River never saw the moon landing video during their lifetimes, but none of them were compelled to kill any Silent they see on sight. With those two episodes being a Stable Time Loop set up by the future Doctor (supposedly), they should have been affected but they weren't.
 * They wouldn't need to. Whenever you look away from a Silent, you forget. It'll be as if there wasn't any change to the moon landing video, and you will never know.Quite simply, The Silence may have used the same trick the Doctor did back in 1969... embed a hidden message into something that many, many people were sure to watch, telling them to submit and listen to whatever The Silence order them to and that this order supersedes all others now and forever (making the moon landing video useless).
 * The Royal Wedding perhaps? 0.5 Billion? NO!! 2.5 Billion. The Doctor would have to wait a while to beat that!

The Silence are behind the whole of Madame Kovarian's operation, and also the attempt to blow up the TARDIS (without knowing the consequences).
The motivation for the anti-Doctor group led by Madame Kovarian still hasn't been adequately explained ('boo-hoo the docter is scary' doesn't quite satisfy me), and the idea of 'Silence will fall' was set up as being way too big to blow its whole load in the first two episodes (and we know that the characters from the Lodger will return...) so after the Doctor destroyed the Silent Empire, they created the Anti-Doctor organization slowly (only took 'em three millenia) as a means of revenge against him. This is actually plan B after plan A - blow up the TARDIS - somehow failed (I guess the voice in the TARDIS just before it explodes is a silence? Maybe).
 * So basically Kovarian is an Unwitting Pawn of the Silence.
 * She's not an Unwitting Pawn. She's willingly working for them.

The Silents are good, but think that the Doctor is evil.
Assuming that the Silents are ultimately benevolent, despite how scary they are, they could be against the Doctor because they see him as a threat. It's been established in "The Pandorica Opens" that much of the universe is scared of him, so who's to say the Silents aren't? They first occupied Earth because it's where the Doctor and so many aliens love to visit. At first, they weren't exactly sure if the Doctor was the monster they'd come to believe. But after theorizing that he may be why Earth is a Weirdness Magnet, and more importantly ordering their execution, they felt it was absolute proof they were in the right. Their alliance with Madame Kovarian is to fight off the Doctor.

How The Doctor will stop the Silents for good

 * He will go into the Time Vortex and broadcast the message from the Silents through every television for eternity, every holoscreen, every phone. Once a day sending out a continuous subliminal message: You should shoot us all on sight. Ever watched an episode of a tv programme again and think "I didn't see that bit last time!" That's because that part was on when the message happened to be replayed. Tinkering in the background. Maybe a little image in the corner. Either way, you will forget and you will do it.

The Silents predicted their downfall

 * They kidnapped Amy Pond because they think she led to their defeat. Let's face it, if Amy was never there, The Doctor would be dead. Also, Amy spawned River Song, who has killed a *LOT* of Silents. So when they said "Silents will fall" they were talking about their own defeat. They had seen it (maybe they're precognitive?) and wanted to stop her.

The Silents made the crack to save Rory's life.
Yes, it seems that Rory is now nigh un-killable. But in "Cold Blood" he should have died, and would have, if the crack hadn't eaten him. The time crack might have wiped Rory out of existence for a little while, but in the long term, it did him a lot of good. It was the crack streaming through Little Amelia's head which allowed Amy's memories of Rory to be kept. It was the crack which allowed the creation of Nestene Romans, one of which became Rory.

So why would they do this? Possibly because they seem to have interest in the time tyke seen in "The Impossible Astronaut"/"Day of The Moon", who was hinted to be Amy and Rory's daughter, and hinted very strongly to be River Song. They might have known that for the her to come into existence, they would have to keep Rory alive, so the child could be concieved. Thus the crack was made to save Rory's life.

The Silence are Slendermen
Or their leader is. They look remarkably similar (Tall, Slender, Male, in a suit) and fans have wanted this for a while and Steven Moffat complied.
 * And after having seen the first episode of Season Six, this guess looks ever more plausible. The business suits, the tallness, the general creepiness, the fact that they mess with memories... It's almost like Moffat has been watching Marble Hornets and said "Yeah, that'd make a great villain!"
 * The one few memories that exist of them are so faint and vague we incorporate them into stories. Creating the illusion that there is only one of them, when there are many identical and also the reason we most often depict the Slender Man as The Blank, because their face is too alien and horrifying for us to take in.

The Silence are both the result and the cause of a massive paradox involving River Song
It wasn't the TARDIS exploding that caused "Silence to Fall" - at least, not directly. It was the fact that River Song was on board the TARDIS when it exploded on Amy and Rory's wedding day. This theory is based on the fact that River Song is heavily implied, if not actually confirmed, to have been conceived that night, River claiming to be a complex space-time event similar to the Doctor, and the Silence claiming that Amy will bring the Silence, which might be a reference to her daughter. The destruction of the TARDIS not only tears reality a new one, it causes a complex space-time event to cancel out her entire existence at the moment of her own creation, causing a hell of a paradox. River says that something is overriding her and driving the TARDIS to destroy itself, and hears a voice state that "Silence will fall". This is actually the Silence using their ability to leave post-hypnotic commands, meaning that River is actually the one forcing the TARDIS to explode, subconsiously countering her own desperate attempts to stop it. Why? The Silence exist in a reality outside of the multiverse and the void, so very different that they can't exist in any reality we would consider normal. They used this paradox as a way to destroy what they couldn't have, or maybe it was a Xanatos Gambit depending on the Doctor cancelling out the destruction of reality, allowing them to slip into it and weave themselves into the reality created by the TARDIS' Big Bang in a way that allows them to exist within our reality - if this is the case, they may also have inspired the creation of the Pandorica for the Doctor to use to save the day. Of course, this means that the Silence would have to have been around before any of this started, but when it comes to Paradox and time travel, Effect doesn't necessarily follow Cause.

The Doctor has encountered the Silence before.
However, he has (naturally) forgotten all about them. One of the Silence mentioned being on Earth since fire and the wheel. The making of fire was a major goal of the cavemen in the very first episode of the series. The Doctor wasn't all that heroic in this episode, so intentional thwarting is somewhat out of the question. Accidental stowaways on the TARDIS perhaps? Stranded in pre-history, their plans for recovery delayed by the Doctor, whether he knew it at the time or not.
 * Well, have you watched "Edge of Destruction" recently?

The Silence are both the remnants of alterations to human history, echoes of future alterations, The Enemy from Faction Paradox, and a link between RL Earth and Who Earth
In the Whoniverse looking away from a Silent means you forget the existence of the Silence. This of course means that a wild mass guessing on the nature of the Silence is impossible in the Whoniverse. Are you looking at a Silent or a picture of one while reading this? Probably not. Do you remember them? Yes otherwise this example would not exist.

Now what else can't be seen unless your looking at it? Changes to Time and of course Plot. Imagine your a girl that hangs out with those two guys then some time traveler changes history and guy one becomes a girl and you now always lived in a harem comedy. where did the first boy go? No where it was silenced by the change to history. Can you see a change to history or remember it if your not a outside observer like say The Doctor. No it simply "has always been that way".

The Silence can affect Time Lords because they exist in a higher order of time. Time lords follow cause and effect time except when traveling. Silence exist in "wouldn't that be neat time" also called 'plot time'. The Silent that killed that woman knew everything about her not because it stalked her but because it was a coporeal manifestation of the ''past'(pre-time alteration) future she will no longer have and the 'future' (post-time alteration) death. The Silence killed her because plot demanded it.

Now then in the Faxtion paradox series the "Great Houses" a.k.a. Time Lords faught a nameless Enemy that was described more as a force of history then an oranization or group of beings. Why didn't the Time lords name this enemy? They only knew it existed due to its side-effects. They forgot what the enemy was when not seeing them but knew the enemy existed. Once everything went to hell with Fation Paradox, the Ancestor Cell, the Celestis, the Remote, and Lady Lolita (who evolved from The Master's old Tardis and takes after her Time Lord) the Silence sliped away so their masters (not to be confused with The Master(unless he's a fan of Doctor Who)see below)could watch.

Now who are the masters of the Silence. The humans from this Earth in particualar those incharge of making teh episodes and other parts of Doctor Who. The Silence never appeared in the library not because we forgot them but because it would ruin the plot twist. Now then the Second War in Heaven ended with Galiifrey's destruction yet it's a different war then the Last Great Time War why? Because until the plot twist Dalek were easier to film then a memetic force thus the Silence altered the time War and replaced it with a different time war that was more coporeal. We can't see how a bio-data virus that alters its victims genes and history works nor have we seen The Nightmare Child (probably not the biological or adopted child of Steven Moffat, too obvious to be a child version of Moffat that escaped into the Whoniverse) but it's easier to imagine something eating a flagship while also properly "big enough" to be incomprehensible.

This of course means that when one decides to explore the setting of Doctor Who a Silence is made to "set the stage" and after that it simply disappears until needed again. They appear in the new series because the Doctor needed something ominous to face that his try to reason with it tactics would not work. Thus the normally formless Silence took form by the orders of the King of Nightmares.

Feel reassured and less paranoid? Don't. Here's how it gets worse. That link they create between the two universes. Nothings stoping anything from finding a way to follow it back into this universe. The Nightmare Child, Skaro degenerations, and the Could Have Been King have to escape to somewhere? Right? Good Day.

So basically its all Steve's fault.

The Silence "convert" people.

 * If the Silence, as revealed in Let's Kill Hitler, is actually not a species, but rather a religious movement, then why are they all identical? The Headless Monks are capable of making a rather, er, fundamental change to your body. Perhaps the Silence run a similar but more elaborate operation, and can reprogram your biology at a basic level to gradually make you one of them...brr.

Jack Harkness was working with the Silence.

 * Or rather, the person who would become Captain Jack Harkness was working for the Silence. We know that River Song, who the Silence were training as a weapon against the Doctor, spends a lot of her time in the 51st century. It's quite probable that the Silence are based in the 51st century. The 51st century is also Jack's native time period. If the Silence is fighting against the Doctor, they might well have asked the Time Agency for help. Given that the Doctor keeps on messing with time, the Time Agency may have seen the Doctor as problematic and supported the Silence's attempts to get rid of him. So they may have sent some of their agents to work for the Silence. In "The Doctor Dances", Jack claims that the Time Agency erased two years' worth of his memory. We know that you cannot remember the Silence (the species version, if not the entire religious movement) after you've stopped looking at them. If Jack spent two years working with them, he probably wouldn't remember most of what had happened. But he wouldn't have been looking at the Silence every single second for two years, so surely he should be able to remember something? Not really -- if the Silence have that much power over someone's memory in the first place, it would hardly be surprising if they figured out how to make someone forget everything they did during a time period when they were even vaguely associated with the Silence.

The Silence aren't, as a whole, actually evil.
Aside from traitors or others coerced in some way, they are more than content to share the Earth and help humanity (and themselves). Perhaps the Doctor was used to try and exterminate them once the Silence organization didn't need them anymore, which nearly succeeded. He will then free and help the enslaved ones, who will then go back into obscurity and live as they always did.

The Daleks from Bad Wolf/Parting of the Ways are part of the Silence
They mention having waited in silence for years. They have guided human evolution via Satellite 5 and the game station. They mention blasphemy and the Doctor asks them 'Since when did Daleks have a concept of Blasphemy? -The Silence is a religious order. And then in series 6, where does the Doctor get his information about the silence? From a Dalek scientist's memories. Now why would Daleks work with the Silence? Because there's something out there they both fear and hate so intensely. The destroyer of worlds, the oncoming storm.

There's a Silent hiding within the TARDIS
At two points in the Lodger, there are scenes where Amy, stuck in the TARDIS as it tries and fails to complete a materialisation, is talking to the Doctor when something odd happens. As the Doctor talks, once in Craig's spare room and once on the football field, Amy looks off screen, gasps and looks shocked and then cries "Hey!" before the scene carries on as usual. During the second time, as she reacts like this, the Doctor says "Hang on" as she cries "Hey!" - she repeats his "Hang on" in an uncertain tone of voice and shakes her head as if trying to wake from a tired state. Later on, as the Doctor and Craig race upstairs to help Sophie and Amy experiences turbulence in the TARDIS, over the earpiece she can be heard to cry "Doctor!", and then inexplicably say "Hang on..." in the same uncertain tone that she did earlier. Her actions here aren't explained. Perhaps the Silent was the pilot of the primitive TARDIS above Craig's flat, and the disturbance that caught the TARDIS was it managing to transport itself into the Doctor's TARDIS. On two occasions, Amy saw it darting away from her out of the room, causing the reaction, but the trademark effect of the Silence kicks in and she immediately forgets it happened. As we also know that seeing the Silence can leave a post-hypnotic suggestion in a person's mind, maybe seeing this Silent accidentally left the Doctor's command of "Hang on" in Amy's mind, which then came back to her mind when she was again in danger of being lost in the Vortex as the Doctor was warning her about. It's not long after this - the next episode, in fact - that the TARDIS inexplicably shoots off to 26/06/2010 with River Song and explodes despite her efforts - was the Silent in the TARDIS sabotaging it? And if it was, was it killed in the explosion, or could it have survived? Could it still be in the TARDIS even now, watching the Doctor? And if it is, what happens when it warns the rest of the Silence that the Doctor survived Lake Silencio?

The Black Guardian is the one behind the Silents.
At the end of the Black Guardian trilogy, the White Guardian said that the Doctor would meet up with the Black Guardian one final time. That has yet to happen. Also, what does the Black Guardian love most? Chaos. Causing Silence to fall by having the question asked? Sounds like chaos if you ask me. It's exactly his type of thing- manipulating other people/creatures to cause the chaos for him, and hating on the Doctor a lot/wanting to kill him.

The Silents are the Doctor and the TARDIS
Even for the Doctor, that was a very unusual regeneration between Ten and Eleven, wasn't it? Regeneration is never exactly quiet, but to create such a blast wave that it destroys the TARDIS console room, causes it to crash, and requires it to completely shut down to rebuild itself? And, on another subject, if the Time Cracks appear throughout time and space, and if the Silence has manipulated humanity since the Stone Age as they claim, why is it no sign of any of them was ever seen until the Doctor regenerated into his Eleventh incarnation?

What if that huge explosion of regenerative energy purged something from the Doctor? And took with it something from the TARDIS telepathically linked to him? Something that manifested into a group of creatures now called the Silents? The memory-proof nature of them? From the TARDIS' perception filter. The energy attacks they use? Energy from sources they draw on in the same way that the TARDIS draws on. Their makeshift TARDIS machine? The result of the Doctor's knowledge of the TARDIS without sufficient or suitable materials to grow a proper one. River Song being as close to a Time Lord as you can get? She may have got a spark of the Time Lord gift from being concieved on the TARDIS, but the Doctor insisted that it took far more than that to cook up a working Time Lord...his knowledge of which the Silence could draw on to create their weapon, just as they could to take control of the TARDIS and blow it up.

So, why are they so hell-bent on eliminating the Doctor, then? Well, maybe they have the shadows of something buried in the Doctor's mind, so deeply not even he can clearly remember it. Something that scared the Doctor a long time ago, so much so that he sealed away his name in such despair, something that he has run away from all his life. The answer to a question that deep down, he knows must never, ever be answered. And if these newborn Silents took a memory from the future, one that the TARDIS could know due to her non-linear perception of time, that told them that one day the Doctor was destined to reveal this terrible secret, what lengths might they go to to stop him?

Eleven is going to change the events of Silence in the Library/Forest of the Dead.
The only water in the forest is the river. "Forest" of the Dead contained "River" Song and piranhas. Air piranhas. Plus, it makes for an epic episode. Donna Noble, Amy and Rory Pond, 11 and 10 all with River. Could you imagine 11 pulling a "spoilers" on 10?
 * If this happens, it'll be in the series finale- firstly because arc words always show up in the last episode(s), and secondly because how else can they top restarting the universe, The Master Race, Daleks trying to destroy all universes, The Year That Never Was, Cybermen vs Daleks vs Torchwood and Daleks on Satellite 5? Also, Rule of Cool demands it.
 * Plus, the main villains of Series 6 are the Silence. Silence in the Library?! Knowing Moffat, he could very well have planned this entire thing out beforehand.
 * Coupled with the IMDB rumor that David Tennant is returning for the season finale, this theory is looking surprisingly likely.
 * Of course, a similar rumor also insists the Peter Davison is in the finale, which would throw a pretty big wrench in this theory.
 * And they're not on IMDb any more.
 * Wouldn't that be interfering with his personal timeline? Isn't that against the rules?
 * There were two children in the computer (Donna's kids) that were still there listening to River's bedtime story with the library's heiress - Amy and Rory?

The Doctor will be captured by the Cybermen and converted into a Cyber Leader
I know this one sounds like it’s REALLY going out there (then again, doesn’t everything else?), but I actually have some evidence for this one.

Now, as we are all aware, Steven Moffat is breaking up the current series in half, to include a “gamechanging” plot twist for us all to speculate over during the summer. But what could be so huge as to bring about such a massive "what the bleedin’ HELL?!?" response? Bringing back a long forgotten, but still immensely popular, villain. But for whom? The Zygons? The Haemovore? The freaking War Lord?!

Nah, let’s just get the Cybermen in there.

But how do I know that? Thanks to this page! If you look long enough, you will clearly find the typed note:

"There will be at least two returning guest stars…in addition, the Cybermen will return to A Good Man Goes To War. [sic]"

Well, golly gee! Good to know the show’s tight-lipped reputation regarding spoilers is still firmly in check.

Of course, if this is a Cybermen story, it has to be a pretty damn big event to warrant Moffat preaching himself on such a high level. And seeing as how he seems to have a good grasp on making the Cybermen terrifying enemies once again, I have no doubt he could think of such a grandiose concept. But if I may, I would still like to imagine how that would work.
 * The summary of "A Good Man Goes to War" is on that page, too, and it says "River Song must finally reveal her most closely guarded secret to the Doctor" Whatever it is, /that's/ what'll cause the high HSQ.

So as we all know, the Doctor was Killed Off for Real by that lake astronaut. I’m going to leave the astronaut’s identity up for debate right now, because it isn’t important for my theory. Rory finds the canoe/boat-thing the Doctor may or may not have left on the shore, and uses the gasoline Everett brought to give the Doctor’s body a Viking Funeral. I will go ahead and assume that the boat sank from the flames burning a hole in it.

Now congruently occurring on Earth in some sort of Cyber Drone camp, tucked away from inhabitable observers, a squadron of servants with knowledge of the future watch the whole scene unfold. After the involved party has left for the diner, the Cybermen traveled to the lakeshore to recover the Doctor’s remains and their automated astronaut suit, developed from a joint Cyber-technology and NASA merger when they invaded the latter off-screen. What’s that? I said I wouldn’t talk about the astronaut’s identity? Well, I lied then.

Using some sort of sciency magic to revive our hero, the Cybermen force the Doctor to be converted into a new Cyber Leader, to which he woefully accepts. They do the deed, and this new batch of robots are led by the Cyber!Doctor, whom is revealed at the end of the episode after all of the invasion stuff happens. SPECULATION TIME!
 * Jossed. It's not a Cyberman story. It's a Colonel Manton-Eye Patch Lady-Headless Monks episode with Silurians and Sontarans as allies. The big revelation is River Song being Amy and Rory's daughter. The Cybermen DO appear, but not in a huge capacity, and only in the teaser, where Rory confronts them.

The Apollo spacesuit is an early form of cyberman technology.
As described by the troper above in The Doctor will be captured by the Cybermen and converted into a Cyber Leader, the idea that the spacesuit is a kind of very early cyber-technology has crossed my mind.


 * We know that  at least some cybermen can 'reproduce' by eating a person alive . A cyberman tried to do this to Amy during The Pandorica Opens, so the writers know that the idea is fairly fresh in all our minds.


 * Meanwhile, it looks like maybe  what the Apollo spacesuit does, among other things, is eat little girls alive , capturing and in a sense enslaving them, but perhaps also giving them extra strength and the ability to survive in environments that would usually kill.


 * I've personally lost track of all the histories of the cyberpeople, but I would guess that, if this is so, that these are probably not the Cybus cyber-people from the other timeline, but could instead could either be Mondas-derived cybermen, or else some completely new version which actually originates entirely on Earth, in a new history/timeline.


 * Jossed by pedantic canon by someone who really isn't a know-it-all, honest. Discounting "The Pandorica Opens", where they had to have used time travel (and even if they didn't, that would mean that Cybermen were perfected in 102 AD, and the eating girls technology would be far more robust with 1867 years of progress), the earliest chronological appearance of the Mondas Cybermen in a recognisably Cyberman form, with or without time travel, was The Invasion (aired 1969, set anywhere between that year and the early 1980s). For budgetary reasons (and in-show, probably due to being a different faction), a less aesthetically advanced Cyberman appears in 1986 (The Tenth Planet), but those cybernetics are still well in advance of Apollo technology. I'm pretty sure in the episode it was implied that the Silence ordered humans to build it, as Silents don't ever make things.

One of Matt Smith's Companions will be a lesbian.
It is only a natural progression from Rose, Martha and Donna. Also, it would drive the shippers insane. Muhahahahah!
 * They've also been randomly making side characters lesbians, like the old ladies in Gridlock and Sky in Midnight.
 * Sort of Jossed, at least with Amy Pond, as she has a boyfriend. Also snogs the doctor apparently.
 * She might still be bi. Well, we didn't see how she reacts to age-appropriate women yet.
 * Did you see the comic relief special? She was definitely flirting with herself then.
 * It is possible that all of Eleven's companions fit every sexual orientation imaginable (assuming Jeff is gay) except lesbian. Why? Because Eleven's relationship with his companions must always consist of two-sided sexual tension.
 * Scratch that. Red Eye with Greg Gutfeld seems to share a continuity with Doctor Who, and the cast of Red Eye has taken a shining to angry lesbians...
 * He's not a proper companion, but Canton got to spend 3+ months working with the Doctor and co. and he's in a committed gay relationship.
 * What about Ace?
 * And in the comics the Doctor has had two lesbian companions and one who was bisexual, those being Izzy Sinclaire, Fey and Majenta
 * They're not companions but the episode 'A Good Man Goes to War' brought us Madame Vastra, a female Silurian who was in a lesbian relationship with her companion Jenny and Moffat has said he is going to bring both characters back at some point. The same episode also brought us the Fat and Thin Gay Married Anglican Marines.

Every time the Master is killed, he'll regenerate into a different Time Lord.
Thanks to the Drums.
 * Corollary: The Doctor will be forced to choose between the extinction of his own race and the human race.

The TARDIS will play a role in the Doctor's final undoing at the end of the Thirteenth or otherwise last Doctor's run.
It doesn't seem to have been working so well lately, and since it's long been implied to be living, even sentient, it could well take offence to being beaten up by Ten simply because he's a selfish psycho who doesn't want to regenerate into Eleven. Plus, it would be a nice Death By Situational Irony - the Doctor's truest companion (none of this Rose or Donna or River crap) proves eventually to be his unravelling.
 * Semi-confirmed, possibly. The Eleventh Doctor's existence completely unravels after he instigates Big Bang II. However, the TARDIS may not actually want the Doctor dead. After unraveling, the Doctor is resurrected by Amy's memories. Considering the TARDIS' behavior in the second half of Series Five, the TARDIS may have been trying to give Eleven and the universe itself a system reset. The universe needed a reset because of the Cracks, and Eleven needed a reset because his sanity had reached its limit.

Amy is not human.
She's an operative from some other planet's equivalent of Torchwood, and attempting to go undercover as a human police officer in order to gather information, but she made a mistake with the uniform. Also, her real form is frog-like. Someone, upon seeing her, made a reference to a pond, which is where she got her surname from. This would also explain why Matt Smith used the phrase "Mad as a box of cats" to describe her, rather than frogs - the poor guy is just that afraid of spoilers.
 * Big Bang II could have split Amy into 507 individuals. One of these individuals could be the Amy we saw in Series Five. The other 506 individuals may be Whovians in the audience and/or fictional characters in non-Whovian fictional works. The Amy we have seen on television thus far does not seem to know what she was getting into when she agreed to travel with the Doctor but she seems up for the danger nevertheless. Big Bang II may have relocated Donna Noble to Pete's World. Donna Noble may have been subconsciously pulling the strings during Series Five, because the memory of the Tenth Doctor could not leave her unconscious mind.
 * Jossed. Her daughter was scanned, showing human DNA (with some extra Time Lord strands due to unrelated circumstances).

The Daleks will exterminate the Weeping Angels
How do you kill a stone? The same way you kill everything else, by shooting with the Dalek's Death Ray thing.
 * Does no one have a sledge hammer these days? Or a cliff. Or an anvil. This troper thinks that what an human would use to destroy stone would be (presuming they were using the best thing they could for the job)just as good as a disentigrator. If those arent disentigrators, maybe even better!
 * Jossed, the bulletpoint at least. Bullets did absolutely no damage in "Flesh and Stone", so a sledgehammer would likely do nothing.

That fanfic Matt Smith wrote about the Doctor meeting Einstein to get into character?
It will become an episode. Except, you know, better written, since professionals would get a crack at it.
 * Keeping in mind that Steven Moffat is the head writer for the series now, more than likely it will involve some Nightmare Fuel, at which point we can never think of Einstein or the theory of relativity without associating it with some Nightmare-Fueled Monster of the Week.
 * Einstein may have had a affair with Marilyn Monroe. The Doctor at some point was married to Marilyn Monroe. Threesome?
 * Kinda-sorta confirmed. There's a mini-episode with Einstein, but it was written by a bunch of middle-school kids, not Matt or any professional writers.

Cybus and Mondas Cyberman will get together and have some Cyberbabies!!!
We know that Mondasians are still out there somewhere, and the Cybusmen won't let being destroyed, sucked into another dimension, dropped into Victorian London, exploded and then sent into another dimension...again stop them. These two groups will meet up and join their sweet sweet....TECHNOLOGY together. With the alternate universe Cyberman lacking the gold vunerability, it would definately have one benefit, and while my lack of old school Whoniverse knowledge prevents men from knowing what the Mondas Cyberman would bring to the Table, they are likely to have something good to offer. And Voila!! Two evil tastes, that taste evil together!!
 * Jossed in part. The Cybusmen weren't sent into another dimension, unless you're some censored dub of Dragon Ball Z. Hartigan blew up at the very least the ones in her immediate vicinity with her mind while the rest of the Cyber King was sent into the time vortex to quietly disintegrate.

The events of Series 5/6 are a recurring loop in time: Amy and Rory have already travelled with the Doctor in his Tardis and are now repeating events
While nobody has a conscious memory of previously travelling the loop, Amy and Rory both have subconscious memories. That's why Amy knew the correct thing to do with the space whale, the Dalek android, and the vampire. It's also why Rory knew what caused the Tardis's 'bigger on the inside' and why he was able to talk about what the Doctor does to his companions as if he'd known him a long time.
 * so what you're saying is... they have entered an endless recursion of time?
 * endless until the Eleventh Doctor breaks the loop - with his 'death'.

Steven Moffat is in the employ of the psychiatry industry.
Why else would someone want to continuously scare kids week after week?
 * He's trying to warn kids about how scary life can get whilst giving them hope. The Eleventh Doctor is televised psychiatric treatment. (Televised psychiatric medication is theoretically healthier than drugs because one's knowledge of somebody else's dream can be managed through their own dreams, while many drugs linger in the body after being administered.)

The Weeping Angels are mutant Imajin.
The sand falling from Amy's eyes were a hint towards their true form, as it tried to possess her. You can now thank the Crack for stealing away the chance of seeing the Tardis and Den-liner flying together in the season finale. Nice job breaking it villain.

Somehow, Amy Pond is really The Doctor and the existence of The Eleventh Doctor as a separate being is a side-effect of Ten's earlier aborted regeneration.
She's saved the day on more occasions than "Eleven" so far and seems to possess a sense of empathy for others that Ten had which Eleven seems to lack completely.
 * This would fit in well with the above theory, re: Eleven develops into The Valeyard.
 * Additionally, The Doctor HAS always wanted to be ginger. Nobody ever said about him staying a man when he did it.

Nothing horrible is going to happen to Amy Pond.
Remember back in Silence of the Library, when River Song freaked out upon hearing Donna Noble's name? Because she knew what was going to happen to her. River didn't have any sort of devastated reaction when the Doctor introduced her to Amy, meaning that she's obviously going to live happily ever after. Obviously.
 * River has seen Amy already, as implied in Flesh and Stone. And since River's coming back for the Finale, I'm guessing this is when they'll first meet. River did allude to the arc words, and she's apparently already been through the finale.
 * ...Well, yeah, but it was a nice thought!
 * This doesn't really mean anything. River knows full well about 'Spoilers' and the damage she could cause by revealing things ahead of time, so Amy very well could die in the finale. Future!River is not the same as River from this time, and might not care as much if something happens to one of the Doctor's companions.
 * It could just be that Donna's fate was so horrible - to actually be forced to forget all about the Doctor, and never allowed to remember, that made River react so. She admitted to Rory in "Day of the Moon" that the Doctor has been an influence on her all her life, so forgetting him would seem like a fate worse than death.
 * Jossed. She witnessed Rory's horrific death (in a dream and a hallucination induced by House, admittedly), was killed by Rory (Only Mostly Dead though), attended the Doctor's funeral after witnessing his own death, got kidnapped without her knowing, spent three months on the run in America, had her mind raped by the Silence (or something like that) and had her baby stolen while its Ganger duplicate turned to mush in her arms. If none of those are "horrible things happening", I don't know what is.

The job of the Eternal is to run away when the Doctor comes calling.
The new Daleks are divided into five castes: the Strategist, the Scientist, the Drone, the Eternal and the Supreme. All the others seem relatively clear, but the Eternal's job description is rather vague. In fact, he is a living archive containing everything required to reconstruct the Dalek race from the scratch in a pinch. Whenever the Doctor makes appearance, the rest send the Eternal packing so that even if they get defeated, the Dalek Empire lives on. They showed some serious Genre Savviness in the Victory of the Daleks, so this kind of innovation would be very much in place.
 * River Song would not allow Eleven to exterminate the Daleks (as Human!Ten did) because Amy Pond sees the new Daleks' value (If the Time Lords re-program the Daleks to work for Gallifrey, they can prevent the extermination of the Time Lord race). Daleks can be used for planetary defense.
 * This will end with the Doctor chasing down the Eternal armed with one of the Anti-Dalek guns, Amy in tow. There will be Scooby-Dooby Doors and Benny Hill will be playing in the background. It will be awesome.
 * It certainly makes the name "Eternal" make sense. Daleks want to be around forever, designating one to make sure they will all be around forever when they have a habit of driving themselves to extinction seems more than prudent. That was (more or less) supposed to be the point of the Cult of Skaro, too, in addition to their mandate of "think outside the box."
 * I support this idea, only because I really want to see the Supreme say "ALL DALEKS TO BATTLE STATIONS", watch the others preparing for a fight...and the Eternal running away screaming. Since he'd be specifically engineered for maximum cowardice, I expect some dialog like "RUN AWAY! WE'RE ALL GOING TO DIE! MOMMYYYY!". Tell me you wouldn't want to see that.
 * If that's the case, I bet the Stone Dalek was an Eternal. Hence why it begged for mommy.

Amy Pond is Donna regenerated

 * She still doesn't remember anything about any of her adventures with the Doctor and her mind doesn't explode because now that she's full Time Lord, she can take it. Come on, how cool would it be if they set this up?
 * Jossed. Amy's daughter is fully human, with Time Lord DNA due to being conceived in the TARDIS mid-transit.

River Song will be a prisoner of the Doctor.
We know for a fact that:
 * In the future River Song will kill a good man, who may or may not be the Doctor
 * In the fifth series finale, River mentions that "everything is going to change"
 * The Doctor will travel with River
 * They get rather intimate (compared to Who standards, that is)
 * "Married couple" feel to their conversation
 * River knows how to fly the TARDIS.
 * She eludes questions about possible future marriages and refers to it as "complicated".
 * She knows the Doctor's true name.

How do we reconcile these facts? One possibility is that the Doctor offered the same deal to River as he did the Master in "The Last of the Time Lords": to be imprisoned in the TARDIS under his protection/guidance. Eventually they get closer (maybe she does something to redeem herself) and she will be more of a companion than a prisoner.

Problems with the theory:
 * There are of course the Stormcage incidents. These happen after her tenure with the Doctor. Maybe she killed enemies too often, (hence the Dalek begging for mercy in "The Big Bang") so the Doctor threw her out. She served y years of sentence with the Doctor, so she will have to serve the remaining x-y in a Stormcage.
 * The Doctor sends her to the Library (Silence in the Library) at the very end of their relationship. Possibly they got together again, or the Doctor - considering her crimes to date - gave her a Redemption Equals Death. (and a cheesy virtual afterlife)

The Doctor Who universe is a later version of the Eternal Sphere, and the Time Lords are 4-D beings who live there as admins.
The Doctor felt that his colleagues were interfering too much in the history of the Eternal Sphere x.0, with the Time War being the last straw, and the lock on the Time War is basically keeping the other admins locked out of the program. For "The Big Bang", the Doctor knew from the original Eternal Sphere program that a system restore was possible, with the help of the minds of Eternal Sphere residents, but he had to go outside the lock he put to keep the other Time Lords/admins out and he wasn't sure if Amy's memories would give him the link he needed to get back into the universe.
 * This would also explain why he remains so insistent that there is no such thing as magic, despite occasionally encountering supernatural abilities and demonic beings- he knows that they're just using system code and from the "hell" Bonus Dungeon, respectively.

In Series 6, River will meet the Doctor for the first time.

 * In the Christmas Special or the first episode of Series 6, the Doctor will encounter River at the earliest point in her timestream. For River, this will be the first time she's ever met the Doctor (Wibbly wobbly, timey wimey, etc...). Expect the Doctor to be that one that starts saying "spoilers!" and such.
 * Jossed, but the mid-season finale shows River at just one month old. However, this is too young for him to communicate with her.
 * The Doctor does speak Baby.
 * For a time (maybe a block of episodes, maybe the entire series), River will be a companion of the Doctor's, travelling on the TARDIS, all that jazz. They wind up in a real romantic relationship; just knowing that they'll probably get together in the future is enough to get the Doctor thinking that maybe she's someone he'd want to get together with. Predestination paradox and all that.
 * Nope, just two-parters as usual.
 * At the end of the series, she'll kill "the greatest man [she's] ever known" and be locked up in the Stormcage. Worse, she'll really piss off the Doctor.
 * Or, she'll kill Eleven, causing him to regenerate into Twelve. Hence her apoligising in "The Big Bang" and saying that everything will change soon.
 * And at some point in the future, there'll be an episode called "The Time Lord's Wife". Just wait, you'll see.
 * Close, it's "The Doctor's Wife".
 * ...which has nothing to do with The Time Traveller's Wife OR River Song (apart from some arc words), so disregard.
 * None of the Doctor's incarnations are supposed to stay dead. Ideally, the actors who play the Doctor move on to other roles when the Doctor regenerates (but actors are people too, so they do what they like). Every human the Doctor has ever worked with is a hive mind of fans. The most recent Doctor(s) did not show his (or their) fans sufficient respect, so BBC America broadcast images of the Eleventh Doctor at gunpoint, so that angry fans would send Eleven to figurative Hell. He fought his way out over the course of a few weeks. The Force is currently in balance (approximately).

The only reason the Doctor's time rewind slowed down occasionally was because of Amy

 * With the time crack pouring time stuff, and the universe into her head for however long, eating her family. She's a time anomaly. An person to whom the laws of time don't work the same way, just like the Doctor, or Donna (because of her future status) or River (because of her time with the doctor and some other unknown things) and etc.. Because the Doctor was in close proximity to a time anomaly, the laws of time were being warped, and the rewind slowed down enough that he could manipulate the past temporarily. But it was still clutching at straws. If the Doctor continued, he wouldn't have had another chance to fall into a crack until the beginning of his existance. Over 900 years at full speed. I can't imagine it would be fun.

The reason the TARDIS exploded was because it got hit by lightning in the Time Vortex
You can see it in the opening titles. Also, Time Vortex lightning is probably more than enough to damage a TARDIS, and the new opening titles appeared when the cracks did. Coincidence? I think not.

River's first meeting with the Doctor will take place in the 21st century.

 * To add to this, perhaps the mid-21st century. I still think she might be Jack's daughter. And Jack's reaction that his own daughter beds the Doctor before he does would be the funniest thing in the whole of time.
 * Jossed. It's in the 51st or 52nd century. Same era as River's scenes in Stormcage.

The Doctor Will Wear His Wedding Clothes Throughout The 2011 Series
Bowties are cool, but tuxes are cooler
 * Jossed. He's invaded America via a Cowboy motif in Series Six.
 * Also Jossed.

The theme tune is currently missing the bass/beat because the master is gone
It's obvious that part of the theme tune and the drumming in the Master's head is intentionally the same, so what if they actually ARE the same thing? during the intro (since the very beginning of the original show) we'd always see the time vortex. So it could of been the drumming was background noise in the Time Vortex simply being played along side the theme tune. It was stronger in the intro for the 9th and 10th Doctor as it was getting closer to that point in his timeline (after the time war had ended and the timelords gone).

Eleven WILL wear a Fez in season 6!
C'mon, Matt Smith will bug Moffat so much that he will go Sure Why Not.
 * Alternatively, The Doctor will get a new Nice Hat every episode, ranging from bowlers to sombreros to pretty floral bonnets but by the end of the episode he'll lose it or it will be destroyed. Then in the season finale, the Master lures him into a trap with a Fez.
 * He wore another fez in A Christmas Carol and he's got a Stetson on in the Season Six preview. Semi-confirmed?

Amy Pond is...
CAL, aka Library Computer Girl. Everyone died in the Library, but she saved them. She has taken Donna out of the picture by erasing her memory in the S4 finale. River was found interesting enough, so she was allowed to stay. Eventually she got tired of watching, and decided to cast herself as a Mary Sue with hidden reality-bending powers. This theory is based on two extremely convincing facts:
 * CAL and Amelia are about the same age and have sort of reddish hair
 * They are not. Amy is 21-22, while CAL is chronologically over a hundred.
 * It's all in the title: *Silence* in the Library
 * CAL is the template of a little girl watching television. Amy Pond is a hive mind of angry fan girls (males and intersex individuals can also be fan girls. Correspondingly, females and intersex individuals can be fan boys).
 * Another possibility is that CAL watched Series Five and got pissed off at Eleven (which led Twelve to get pissed off at CAL).

River never meets the Doctor past his eleventh incarnation.
Instead she meets the Master, who fools her into thinking he is the Doctor, as part of a Xanatos Gambit or you know...just for the evulz.

When Amy and Rory leave the TARDIS it will be because Amy gets pregnant.
Basically, just because it's the happiest way I can think of for them to leave, and Moffat does seem to be a fan of happy endings. And it would be nice for the Doctor, after Rose and Donna's exits, and Martha disappointing him with her career choice. It would also mean they could still appear in the show from time to time when he goes to visit them (Uncle Doctor!) and... well, I just want it to happen.
 * Agreed. This is the only way I can see it happening, frankly, and I definitely do not see either of them getting killed off at all. Seriously, Rory's been killed or assumed dead like, three times now? I can't take another one!
 * But who would be the father of the baby? Considering the things Eleven almost does, I think the baby would have two fathers (Eleven and Rory). I realize that Time Lords are supposed to be sterile, but if Eleven can create another universe, perhaps he is an exception to this rule. (Or perhaps he shall conclude Series Six by getting Amy and/or Rory pregnant with the current Whoniverse).
 * Perhaps Rory will turn out to be sterile, and they go to find a Time Lord Loom. But, being Time Lord tech, it needs Time Lord DNA to work. So the Doctor sonics it so that it will take 3 DNA samples instead of two, making the child part Rory, part Amy, part Doctor. Could make a funny call back to the movie (just to toy with the fan rage), with Amy or Rory saying "So, I guess that makes (him/her) two thirds human on (his/her)'s" causing the Doctor to cut them off with "Do not complete that sentence." When asked why, he replies "Horrid memories. Seriously, I don't even want to remember that stupidity."
 * Kinda Jossed AND Confirmed, Amy has given birth to River Song and got pregnant inside the TARDIS. However, Amy's physical body was stolen away to Demon's Run, where she was connected to a Ganger body via the TARDIS, so up until "A Good Man Goes to War", she had both left and not left the TARDIS.

The Master will return in a new regeneration -- played by David Tennant.
The Master somehow finds a way to manipulate the DNA and/or physical appearance of his next regeneration, and takes on the appearance of The Doctor (pre-regeneration, because that's what The Master knows). He then masquerades as The Doctor, eventually meeting River Song in this form (explaining how she recognized him in The Library, even though that was the only time Ten had ever met her.)
 * River probably has a picture ID for each of his reincarnations. It would make sense given how she's dating/married to the time traveler who also changes faces every so often. It's only good manners to give a full time history in case of accidental crossings.
 * True, but River only met him once as Ten, but from the way she acted it seemed like she had seen him in that body before. She was surprised when he didn't recognize her.

When The Master goes on his evil rampage for the season - taking over the TARDIS and causing the events of Series 5 - River Song is forced to kill "the Doctor" to stop him, landing herself in jail.
 * This troper likes the idea, but the voice we heard in the TARDIS is nothing like Tennant's. Perhaps if River shot the fake Doctor, getting arrested for his murder (though thinking she stopped him), but he holds off his regeneration and then turns into the owner of that voice...?

A human will become a Time Lord.
This seems fairly likely to happen at some point. It was at one time mooted that Ace would attend the Prydonian academy and become a 'Time Lord' by studying; this seems unlikely now that Gallifrey is [Almost Dead] and the Time Lords are evil. The more probable option is that a human comes by a chameleon arch in some way and is able to rewrite his or her DNA to become a Time Lord. When you think about it, this could be a way to introduce a whole new race of Time Lords made from humans the same way the Daleks have been brought back, ooh, four or five times now? As the chameleon arches create implanted memories as well as changing physiology, they could even bring back the Gallifreyan civilization to some extent at the same time.
 * You could argue that Amy and Rory are the Doctor Donna regenerated by the Master (perhaps using a chameleon arch) to turn them into full Time Lords with a balance of human and gallifreyan DNA that leaves them mentally unbalanced, but still able to think. It fits that the Master would be responsible for this, because the Master is responsible for the creation of the Eleventh Doctor. The Eleventh Doctor may be the Master's Cosmic Plaything. Romana demonstrated the ability to choose her own DNA when she regenerated, so the Master may have programmed a new genome for Donna Noble that would fantasize about the kind of Doctor the Master wanted to exist. (See WMG: The Eleventh Doctor is the Master's Cosmic Plaything).
 * The second point is Jossed. Discounting the trace of Time Lord DNA as a result of the Temporal Schism, Amy and Rory's daughter is human.

A Time Lord will be forced to regenerate in order to evade capture.
Because it would be cool!
 * Hmmm, you might have something there. It is often assumed that the reason River was imprisoned is that she killed the Doctor, right? Well, supposing he was about to be captured, but his persuers didn't know about the whole "regeneration" thing. So River shoots him in front of witnesses, and then somehow has the body moved before he can regenerate. Everyone assumes they just witnessed a murder, and she has to play along and plead guilty to protect him.

Prisoner Zero will return.
He seems to know far too much about the Doctor, the Pandorica and the Arc Words for the next season (Silence will fall!). This suggests that their meeting in The Eleventh Hour was not the first from Prisoner Zero's point of view, not unlike River Song's backwards encounters with the Doctor.

It was never revealed why Prisoner Zero was imprisoned. Given Moffat's penchant for revisiting earlier stories (especially in The Pandorica Opens), this may end up being something very important. His designation of Zero suggests that he is the most dangerous prisoner the Atraxi have, and the fact that they were willing to destroy the Earth to kill him further suggests it.

It is possible that the Doctor will meet him again (along with Amy), and he will commit whatever act or horrible crime he ends up locked away for.
 * Also, his number. He has a low number like he was the first to be imprisoned where he was. And as i recall, that was on the other side of the time cracks. Someone so powerful that a race capable of Ret-Gone considered him enough of a threat to imprison him outside the universe? Sounds like prime Big Bad material to me.
 * He may be a key player in an alliance of Beasts Below. (see WMG: The War is not over.)

In Series 6...
Another of the Virgin New Adventures will be adapted. Specifically All-Consuming Fire. However, it will be an updated adaptation with the 11th Doctor and set in the present day with the Benedict Cumberbatch and Martin Freeman version of Holmes and Watson. With Moffat working on both, he really should do it...
 * Jossed.

River Song's relationship with the Doctor is related to another Chameleon Arch incident.
Sometime in the future, the Doctor picks River Song up as a companion. They travel with each other, but River doesn't end up being anything more than what the old companions were. Then some disaster happens, forcing the Doctor to once again use the Chameleon Arch and take on the disguise of "John Smith". River poses as his wife or possibly even gets married to him.

This is where things get a little complicated for River. She falls in love with "John Smith" and his Human characteristics, which puts River into further doubt about whom she should choose, the Doctor or "John Smith". (Possibly in her romantic feelings for "John", she marries him during this time point.) As the danger strikes nearer and it turns out the Doctor needs to return, River is put in a horrible debate: risk the future of Earth (or the galaxy or whatever) and keep "John" or kill her lover and bring back the savior of the universe. Possibly even whatever alien threat is striking will tempt her with the possibility of keeping "John". However, River eventually makes the right decision, bringing the Doctor back and effectively killing "a hero to many", the "best man [she's] ever known".

The Doctor is touched by her romantic feelings or impressed at what she did to save the universe and starts to trust her more intrinsically. By the time he's sent her back, he's told her his real name and given her a sonic screwdriver, either as a true sign of trust or as a Trust Password to himself to enact a Stable Time Loop. River, indeed, gives that vague answer of either being married, wanting to marry the Doctor - or something along those lines, because of the Doctor's Human self.

The Doctor never told River what order his regenerations come in.
When River met 10 in the library, she assumed it was a Doctor from later in her personal time-line, and treated him as such. Of course, the Doctor (from his point of view) had never met her before, and we don't see him meet her again before he regenerates. Many people have wondered, therefore, why she assumed this.

It must be because even though she has pictures of all the Doctors, she wasn't told which order they come in. Why not? Either the Doctor is really that afraid of spoilers (and considering how she 'died' and the events leading up to it, this is plausible) or he just really likes messing with her.
 * Nah, it's simpler than that. The Doctor hasn't given pictures of his other regenerations to River, because he can't give her future ones, since he doesn't have any, and there's no need to give her any pre-10, because she never met them. The reason he didn't give her any pictures of 10 (while he was 11) is that that would make a paradox, since he knew that River, when she met 10, didn't realize it was 10. Meanwhile, River, meeting 10, obviously noticed it wasn't 11, and, since he'd answered her summons, assumed it must then be a future Doctor, since those would be the ones who would know about her.

The Silence is actually the Big Good of the next series.
"The Pandorica is open, and Silence will fall." We all keep assuming that will mean the entire universe will go silent, which is a bad thing. But maybe the Silence is a person/thing (evidenced by a character named 'The Silent' listed for upcoming episodes), and its falling means it will be defeated. The only reason Prisioner Zero would have taunted the Doctor about this is because the Silence is something very important.
 * You're probably right about the Silence being the Big Good of the next series, but Silence falling may not indicate that it is defeated. Rather it may indicate that the TARDIS' temporal energy (which may be responsible for the TARDIS explosion), has been released and stabilized somehow. According to my theory, the TARDIS has an infinite supply of temporal energy that can be released and/or stablized by imprisoning Eleven in the Pandorica, flying the TARDIS, activating the Friction Contrafibulator (it is possible that the Friction Contrafibulator can be and has been activated remotely from any location but requires the activation of the Zig-Zag Plotter to self-activate), activating the Zig-Zag Plotter, using the sonic screwdriver, and Eleven stabilizing the TARDIS through sheer force of will. Imprisoning Eleven inside the Pandorica, stabilizing the TARDIS with the sonic screwdriver, and stabilizing the TARDIS through sheer force of will are unhealthy ways of stabilizing the TARDIS and only work temporarily. The TARDIS was meant to be stabilized by flying the TARDIS, breaking the Heisenberg Uncertainty Principle with the Zig-Zag plotter (the Heisenberg Uncertainty Principle is a metaphor for the uncertainty of Eleven's moral decisions), and (especially) activating the Friction Contrafibulator. Eleven is willing to fly the TARDIS and activate the Zig-Zag Plotter, but the Friction Contrafibulator scares him shitless, so he decides to stabilize the TARDIS through brute force of will with the help of the Pandorica and his sonic screwdriver. (There is evidence in "Vincent and the Doctor" that the sonic screwdriver can be used to stabilize the TARDIS in a healthy way via one of the screwdriver's "Prozactic Settings". Eleven uses this setting on the Krafayis with a result that he perceives to be unfortunate, and swears to never use this setting again.) It is unknown whether or not Big Bang II changed Eleven's TARDIS stabilization ethos.
 * Jossed. Big Goods don't hide and act all smug around the Doctor.

The War is not over.
Rather, it is just beginning. The TARDIS explosion was caused by the TARDIS' heart overloading from lack of use. The War is between the forces of Order and Chaos. On one side of the War are visible monsters who go to ruthless lengths to enforce order in the universe, such as the Daleks, Cybermen, and Atraxi. On the other side of the War are invisible monsters who work to promote chaos in the universe, such as Prisoner Zero, Omega, and the Starwhale. The TARDIS exploded because the Eleventh Doctor is an infinite power source. Eleven is a massive power source because the TARDIS converts his artron energy into temporal energy and stores it in the TARDIS' heart. The monsters who like chaos (who I shall henceforth call the Beast Below Alliance) want to use the TARDIS' pent up temporal energy to destroy the universe. The Alliance promoting order (who I shall henceforth call the Borg Alliance) want to stop the TARDIS from exploding by stasis-locking Eleven by imprisoning him inside the Pandorica. The Borg Alliance succeeds in stasis-locking Eleven and the TARDIS, but does so too late, so the TARDIS ends up burning up in a star-like explosion instead of completely exploding, and destroying the universe entirely. Eleven was wrong when he said that the memory of the universe was contained within the Pandorica's "restoration field". That "restoration field" was actually designed to spread the memory of the universe rather than create it. Eleven has spent the entirety of Series Fnarg generating his own brat pack of Universe Clones (or gametes), so he decides to end the first battle of the war with a compromise: He shall destroy the current Whoniverse, and procreate a new one using the brat pack. He erases his own existence in the process, and it is uncertain whether or not Amy will be able to remember him back into existence. To Eleven, this is an acceptable risk to take, because he secretly wants to kill himself anyway. Luckily, Amy does remember him back into existence. This means that the Doctor's previous incarnations were erased from time, and Eleven is Amy's imaginary friend made real by Amy's ability to imagine people and things into existence. This means that Amy is now responsible for the existence of Eleven's infinite power source.


 * This is a very interesting theory, but the only problem is that the star whale is good. So why would it join a group that wants to destroy the universe?
 * Lets say it runs of Dark Willow Logic. It senses all the pain and suffering and wants to end it. Unlike Dark Willow, who sensed the Earth's pain and suffering, it feels the pain and suffering of the universe. Using DWL, it decides to destroy it.

Time Lords are Real
Steven Moffat's Whoniverse represents two actual parallel universes. The main characters of Series 5 represent actual forces in our universe. If the actors are only allowed to view their own lines, then Series Fnarg was a Fake Reality Show, and Series Six will be a Twisted Reality Show. Young Time Lords who enjoy Steven Moffat's writing are currently mobbing the Eleventh Doctor with Artron Energy in an effort to regenerate him. Our reasoning? The Series Seven Finale will bring about the Messianic Age in the Whoniverse and undo some of the damage caused by Rassilon. In our universe, the Series Seven Finale will undo some of the damage caused by St. Augustus.

What this implies:

The Series Six Cliffhanger involved Rory Pond trying to snog Eleven. Until this turning point in the series, Eleven body swapped with an entire harem of the Tenth Doctor's companions. When Amy snogged Eleven, she started his Tenth Regeneration, which enabled Eleven to "come out". Rory's snog with Eleven started a regeneration which enabled Eleven to "come back in". Rory Pond represents the Yin force and Amy Pond represents the Yang force. The "Deranged New Whovians" are young Time Lords. We are now mobbing Eleven with artron energy, so that he will come back out half-way, thereby balancing these forces in the Series Seven Climax, and repopulating the Time Lord race.

Except we don't actually have two hearts. We're really just a bunch of old souls with young minds. Shortly after his birth, the Eleventh Doctor was bullied into denying his own identity by the inhabitants of a Country Village. Many of us went through a similar experience. If we seem like attention-whores, this may be the reason why.

The Tenth and Eleventh actors are actual incarnations of the Doctor who performed a Body Swap in Real Life (even I'm unsure about this one).

The Silence is Faction Paradox
Cracks in time, the unraveling of timelines, people, whole races, the universe being deleted from existence...Series/DoctorWho hasn't just been holding the Timey-Wimey Ball, it's been playing hopscotch with it for all of 2010, not least of all the Doctor himself. This sounds like their brand of antics, if dialled down slightly from their source material.
 * Sounds about right. One of the writers seems to have deliberately damaged the Robot Unicorn, while a more naive writer played along with what may have been the stories of her dreams. There may or may not be an Emo Kid buried under Stonehenge. If there is, he would like you to help fix the transmitter (or something, he would be the tetchy one).
 * ...what? Uh, could you explain all that? Admittedly, I haven't read any Faction Paradox novels, but...you know...)
 * Are you familiar with Linux and/or the Matrix films?
 * Apparently not as well as I thought.
 * On December 18th, 2010, at least one Orchestra Conductor attempted to enable the Eleventh Doctor to intervene in affairs of the universe by conducting orgasm-inducing Christian classical music. This somehow worked, at least in the sense that somebody actually seems to care nowadays. Scientifically speaking, humanity popped the membrane of the universe during those Orchestral songs (theoretically by "regenerating" but I'm not sure how that's possible). There is at least one Orchestra in China who seems to be doing the same thing, and one Orchestra had a Gallifreyan guest-violinist who may have performed this task in Europe. Now that the membrane of the universe is popped, we can better perceive the presence of alternative universes, and can become 4D admins of this universe (some of us can anyway). I know this all could be bullshit, but it is the mythology that the media has fed into my brain. Apparently the universe runs on linux (or does now anyway). Our previous universe ran on root, the universe we live in now runs on GNU (although I could be wrong about that one). This is the equivalent of waking up and escaping the Matrix, only to find yourself in another larger matrix surrounding the first one.

There will be a spin-off of Moffat's Whoniverse called Blow Torch
The weird episode that attempted to repair Davros indicates that Jack Harkness and the Eleventh Doctor are different incarnations of the same character. The Eleventh Doctor seems designed for an adult hook-up series, but that would spoil Doctor Who. The solution? Give him an adult spin-off. (Or just a life outside of work).

The Guardians are behind the events of seasons five and six.
The two Guardians are playing a game of Xanatos Speed Chess with each other, and both are trying to manipulate the Doctor for their own purposes. However, as they caused the Time War (come on, something that big has those two written all over it), they can't let the Doctor know it's them, as he's understandably a bit upset with them. In the trailer, it said that Amy, River and Rory had been recruited, and we also have a shot of the Doctor imprisoned, which could be to do with them. This implies that:
 * River is working for one of the Guardians, and she might possibly recruit Amy and Rory too.
 * The Black Guardian made silence fall, and was probably the Man Behind the Man for the Alliance (the BG hates the Doctor too, so it'd be an ideal opportunity to get rid of him).
 * That Woman in White is the White Guardian, or one of her puppets.
 * Of course, the Doctor will find out at some point, and when he does? Yeah, he's not gonna be happy, expecially if the Guardians DID cause the war. And even then, this is gonna get complicated, especially if the Guardians bring people back. Jenny, anyone? Or the Master? The Rani?
 * If the Guardians inhabit Real Life, then the Eleventh Doctor did find out. He was happy about it until the Guardians told him things he did not want to hear.

The Silence are Woobie Destroyers Of Worlds
They tried to get rid of space and time because the existence of space and time is intensely painful to them.
 * Perhaps they enjoy space and time very much. Universe I was merely incompatible with our genetic programming. We could not be ourselves without violating social taboos. We still can't be our full selves at every moment, but Eleven seems to have attempted to create a more efficient system in which the Doctors can dump each other's Rage and other Emotions on each other, and achieve full Freudian Development within Five years instead of Twelve years. We have always used our Weirdness to entertain people, the main thing that has changed is Efficiency, but I doubt either of us are ever certain about anything. Eleven might be, but I'm not.

The fez is a Time Lord and it regenerated into the stetson
After being cruelly killed by River Song, the fez regenerated. When the Pandorica exploded, The Second Hat was scattered across time and space, until it was found wherever The Doctor finds it at the beginning of the next season. As the trailer showed us, The Hat is once again shot by River Song, after which it will probably regenerate again and find its way back to The Doctor (its grown fond of him you see). Maybe next time it will be a sombrero or a bowler or a top hat. And every time it finds The Doctor again, River is there to kill it again.
 * If I'm the Fez, I regenerated into a Top Hat, Alice in Wonderland, and a Cowboy Hat.

Doctor Who: 2010-2015
2010: Series Fnarg (The Tenth Doctor regenerates into Albus Severus Potter and fucks everything up). 2011: Series Shag (The Eleventh Doctor regenerates into Jeremy Clockson and picks up the pieces). 2012: Series Storm (The Twelfth Doctor regenerates into Sarah Palin and takes over the world). 2013: Series Sparks (The Thirteenth Doctor regenerates into Bloom from Winx Club). 2014: Series House (The Fourteenth Doctor regenerates into Thirteen from House and is played by Olivia Wilde). 2015: Series Honey (Amy Pond gives birth to the Twelfth Doctor: Alice in Wonderland).


 * The 2010-2012 series titles are all Jossed, so far as I can tell. Plus, the Tenth Doctor regenerated at the end of series 4's specials.

The current Eleventh Doctor is Ferb Fletcher, and the current Twelfth Doctor is Vanessa Doofenshmirtz
One can deduce this logically by observing the Eleventh Doctor's words and behavior in A Christmas Carol.
 * What current Twelfth Doctor?

The Eleventh Doctor is a Gallifreyan manifestation of Vashta Nerada
Amy Pond, Rory Williams-Pond, Vanessa Doofenshmirtz, the Krafayis, and the Grooveshark (shark seen in A Christmas Carol) are also manifestations of Vashta Nerada.

Every ally and/or companion of the Eleventh Doctor has a corresponding character on Glee
It would explain why Puck got locked in a port-a-potty for twenty-four hours. The Eleventh Doctor's TARDIS looks like a pimped out port-a-loo.

Celebrities are manifestations of Auton Rory and the Eleventh Doctor is Davros
You will be assimilated...

The Seasons of Doctor Who are equivalent to deranged Shakespeare plays
During 2010, the Eleventh Doctor played a Romeo and Juliet subplot while the Tenth Doctor decided whether or not to be born as Hamlet. During 2011, Romeo broke up with Juliet.

The witch from the upcoming film Season of the Witch is Prisoner Two in the Whoniverse
According to Whovian numerology there are, as of midnight tonight, between twelve and forty-two Prisoner Twos.

Doctors Eight through Fourteen serve complimentary functions
The Eighth Doctor and his ensemble suffer at 8PM daily, the Ninth Doctor considers the implications of the damage caused by the Doctor and the Master in the Last Great Time War, the Tenth Doctor does his best to maintain his sanity after remembering the heartbreak he has experienced in his last few incarnations, the Eleventh Doctor barfs Theories of Everything at at least one imaginitive denizen of Real Life, the Twelfth Doctor attempts to cure the Eleventh Doctor's mental imbalance, the Thirteenth Doctor suffers in silence, and the Fourteenth Doctor breaks up the Eleventh and Twelfth Doctors, which cures the Twelfth Doctor's mental imbalance.

The Silence is linked to the Doctor being the last of his race
"When you’re alone, Silence is all you see,/When you’re alone, Silence is all you’ll be."

I can't say just yet whether this pertains to just the Doctor or the last members of a race as a whole, but there is a crude correlation:
 * 1941 crack - Seen only after the demise of the last three post-time war Daleks. The events of Stolen Earth were already time erased.
 * 2010 (Lodger) Crack - It appears/is around the time the Bio-Tardis incident. A one of a kind ship with a crude AI and unknown creators.
 * 2020 Silurian Crack - The last known home/stronghold of the Draconians, at least in the belief of this group of them.
 * 3295 Beast Below Crack - On the haul of the ship where the last evacuees of Earth are riding on the back of the last Star Whale.
 * 51st Century Weeping Angel Crack - On a ship containing a lone Weeping Angel, maybe the last free one, looking to rescue his kind.
 * No seen crack, but mentioned and silence in Venice - Rossanna and the Fishpires attempting to save their race after fleeing through a crack to escape their doomed world.

A lot of cracks, though some are the cause of this phenomon, appear near or are involved with the last of their kinds.
 * The closing of the cracks may then have signaled the repopulation of the Time Lord race. The Eleventh Doctor said he had 507 regenerations in Sarah Jane Adventures, and Saturday Night Live seemed to merge its continuity with Doctor Who at least temporarily. Those 507 regenerations may visible as SNL characters.

The Doctor's continuity is consistent with that of male protagonists in a lot of children's programmes
Danny Phantom, The Fairly Oddparents, Jimmy Neutron, and Phineas and Ferb are consistent with the Eleventh Doctor's continuity. The Eleventh Doctor of 2011 can be compared to King Pariah in Danny Phantom (except Eleven can be much nicer than King Pariah).

The Eleventh Doctor is the Master's Cosmic Plaything
I imagine Doctor Who recruits the next Doctor through the following technique: Holding auditions in hopes of finding an affiliative Time Lord to play the role, casting an actress who is good at portraying the audience's current feelings as his companion, and broadcasting this fiction to the world. If somebody figures out what they are doing, and sees how the current Doctor character connects to the imaginary friends of themselves (or perhaps their peers), they earn the right to play the Doctor (although I suspect nobody had every piece of this intellectual puzzle before 2010).

The Eleventh Doctor wanted to be dreaded
Watching Series 5 may expose fans to the Time Vortex. Schizophrenia may be the real-life counterpart of the Time Vortex.

The Eleventh Doctor is made of anti-matter and the ten? members of his ensemble are made of matter
Metaphorically speaking. It would explain why Eleven was able to reboot the universe with another Big Bang. The first Bang Bang, if I am recalling correctly, is theorized to have resulted from a reaction between matter and anti-matter.
 * If the Time Lords of the Whoniverse are the Nibblonians of the Futurama universe, Amy and Eleven's kiss may have caused Big Bang I (or represented Adam eating forbidden fruit in Genesis).

If the Eleventh Doctor said 'we've got the Brat Pack' he was referring to the actual Brat Pack
Sarah, from Kyle XY is a regeneration of the Eleventh Doctor.

Every near-human species from the Whoniverse, is a spiritual ethnicity of Real Life
That means the Reapers are still here, but are no longer angry. Why? iPhones are now easier to use.

Amy is a spinoff of the Arisians' breeding programme
She's got the height, the red hair, the tawny eyes and the temperament. She may even be an ancestor of Clarrissa Kinnison.

The Eleventh Doctor is Kim Possible with her lying capacity turned off
Steven Moffat and Stephanie Myer had become terribly confused, so they joined forces and became Philip J. Fry's brainspawn; Stephanie Moffat, Matt Smith, David Tennant, Susan Myer, Georgia Moffet, Celia Abigail Lux, Amelia Victoria Pond, the V, Alexandra Elizabeth Lutz, Behavioral Economist, Freakonomist, Honest Journalist, Hope, Jeff Bracewell, and Oscar Wilde.

The Eleventh Doctor enslaved the Rainbow Dildo Daleks
Otherwise known as fan girls.

The Thirteenth Doctor has at least four bodies at any given moment
Eleven, Simms!Master, Captain Jack Harkness, and Jenny.

The Twelfth Doctor watched "A Christmas Carol"
Eleven and Twelve had a Battle Cursed with Awesomeness.

There will be an alien enemy called the Fnarg.
And their group/organization/tribe/whatever will be called the "Series Fnarg". Just to poke fun at the fans.
 * Perhaps the term "fnarg" refers to either a twist on the word "hark" (sort of like Pinky's proclamations in Pinky and the Brain, or a nonsense word to represent the Holy Grail the surface of the ocean, and cusps in general).

"How could a fellow Gallifreyean stoop so low?" refers to...
In The Brilliant Book of Doctor Who there were a series of teasers, the above message being one of them. This could refer to:
 * Any Bad Time-Lord
 * This teaser could just be a red herring; it could simply be one of the Doctor's lines where he laments about something evil another Time-Lord did. (Top guesses being the Master or Rassilon.)
 * The Master
 * It hasn't been so long since the Master's last appearence, but he may always come back and taunt the Doctor.
 * Susan Foreman
 * One of the other teasers had the message "Susannah's still alive", giving a chance that maybe the Doctor's granddaughter will finally return. Susan was of course the name she went by; but Susannah may be her full name, or perhaps she's changed it over the years.
 * She snorted Nine and died of a Trope Overdose...
 * Whoever built The Lodger!Tardis
 * In 'The Lodger' we were introduced to a new TARDIS, one which has also been seen in the Season 6 teaser trailer. To build such a machine you'd need to have lots of knowledge of time-machines, and its plausible to think this person may have been a Gallifreyean whose own TARDIS was destroyed in the War.
 * Romana
 * The Rani
 * Another old baddie. Whatever she did must have been pretty bad, since the bar is already pretty low (what they tried to do to win the Time War or pretty much anything an evil Time Lord has done in the past). It may be whatever she did to keep from fighting in the Time War (even The Master had the decency and courage to fight), followed by escaping the destruction of their race.
 * The Rani is also an Evilutionary Biologist with a penchant for experimenting on species. Human Resources would be a good way to get The Doctor into shock of that sort.

Another possible teaser in the Christmas Carol Song
Amendment: "Let in the shadow", add to it the "halfway out of the darkness" theme of the episode with a dash of the "trying to anger the doctor" subtheme of Series Fnarg with the peppering of the coming Valeyard served on a slice of "Time can be rewritten". Assuming Handy's creation is a regeneration then it is up to the 11th Doctor to face/become the Valeyard.

The Christmas Carol episode and the Eleventh Doctor are absolutely flippant about rewriting history and time. Heck, I wouldn't be surprised if he used the Tardis to get his choice seats at movies and McDonald's. It is possible that the Elventh Doctor may attempt to remove the darkness/shadow (through time travel to prevent its/his creation) from himself and this becomes the Valeyard. The Valeyard will need to be "let [back] in" into the Doctor.

Stable time loop and mysterious vanishment of the Valeyard in the TV series explained. He vanishes abruptly after being he was hinted to live because Eleven takes him out that quickly after fulfilling the stable time loop.

Prisoner Zero was working with "The Silence".
He knows too much for it to be mere coincidence. He's omnicidal enough to have a world destroyed with him. Not to mention the Atraxi were willing to broil the Earth and its seven billion inhabitants just to get at him. He joined The Silence either because he's not from this universe and has an unknown grudge against our own, or simply because he's an Omnicidal Maniac who wants to see the universe ret-goned.
 * Or perhaps he is the evil twin of Ender the Xenocide (from Ender's Game by Orson Scott Card).
 * Now that The Silence has been revealed to be a religious order, not a species, it's entirely possible that he's a Silent.

Eleven is CAL
In the novel Middlesex by Jefferey Eugenides, Cal was born intersex. Cal's parents thought he was a girl until Cal experienced male puberty. The Master resolved Cal's gender issues by splitting him into a pair of fraternal twins: CAL and the Eleventh Doctor.
 * Jossed. CAL never reached puberty, male or female, before becoming the central Node of the Library.

Human!Ten is Matt Smith
If you can read this, you are a Time Lord.

The 000-virus seen in the Eleventh Hour is causing the cracks
The Doctor told, that it is a little bit alive. Maybe it evolved and learned in the mean time everything about Tardis Technologie. And it learned, that the Universe is flawed (or something like that) and planed to destroy it, to start a new more elegant solution.
 * I just saw it. The Virus will reset everything. And destoying the universe would be the mother of all resets!

The Dreamlord is not the Valeyard
Because the doctor has previously met and had a confrontation with the Valeyard. The doctor will actively prevent the creation of the Valeyard, so his dark evil side takes on a different form; the Dreamlord.

The Silence is not a what or a who, but a WHERE
.

A location, maybe a planet or city. And it will be conquered.

The Dreamlord is the Master
We never saw exactly what happened to the Master, and considering how many times villains can be gone for good in Doctor Who, it's quite probable he'll return at some point. I propose that, somehow, some part of his consciousness ended up in the Doctor's mind. The Doctor didn't notice because he was highly stressed, and then he regenerated. When something happens to weaken the Doctor's will, these remnants of the Master's personality will be able to manifest themselves, in the form of the Dreamlord. They were also responsible for the Tardis blowing up; even if just once, they managed to gain control long enough to sabotage things.// Just don't ask me how this happened. I'm sure less plausible things have happened.

Series 6 will feature Nine/Ten's TARDIS
If you pause at exactly the right moment at 0:37 in one of the trailers, you'll see this: http://img855.imageshack.us/i/tenstardis.jpg/ Yeah. Eleven's TARDIS doesn't have those curvy support beam-thingies. Nine/Ten's does. (Also a lot of people were saying that the people looked like Ten and Rose, but it's pretty obviously Rory and Amy.) My guesses are that the Silence somehow puts them into the actual old TARDIS or whoever was making the TARDIS from "The Lodger" made it in the same design as Ten's. Either way sounds suspicious, but there is no way that's Eleven's TARDIS.
 * Partially confirmed in "The Doctor's Wife". It's still Eleven's TARDIS, but there's an archived control room which is Nine and Ten's.

The Black TARDIS seen in "The Lodger" is...
...a human's attempt to reverse engineer a TARDIS
 * The Doctor has showed off his TARDIS to so many of Earth's greatest thinkers / scientists / leaders / madmen that he has inevitably twisted our eventual attempts to build a functional time machine to the point where we think it needs to look like his.
 * that's why it is convinced a human is a viable pilot. It was built by them, it's just looking in the wrong era.

River is the Doctor's mother

 * The Doctor never told The Doctor his name River gave it to him and she calls him sweetie because moms call their child that also the person that thought River how to fly the TARDIS was her husband however The Doctor doesn't know that River is his mom and will be huge shock to him when he finds out.
 * Don't want to burst your bubble but in the Library episode she said very distinctively that it was the youngest she had ever seen the doctor and then she died...
 * Plus, in Day of the Moon, she kisses him. So, yeah, I really doubt they're related.
 * Explicitly denied by Moffat.
 * I know I know I made that theory BEFORE I saw The Doctor kiss her.

There are two Doctors and two TARDISes, having split off during the Tenth Doctor's explosive regeneration.
The Doctor we've seen throughout Series 5 is only one of them. His TARDIS was badly damaged and underwent a complete internal makeover (a regeneration of its own, so to speak).

The other Eleventh Doctor, meanwhile, while looking and acting exactly the same as his 'brother', didn't end up in the same place after his regeneration and never met Amy or Rory. His TARDIS also wasn't damaged much or at all, and continues to look the same inside as Nine and Ten's.

This Doctor didn't take any companions and went off on his own adventures during Series 5, and may or may not have had a few encounters with River Song along the way.

Something like this could explain:
 * The presence of what appears to be Nine/Ten's TARDIS in an upcoming Series 6 episode. It's actually the other Doctor's, and would probably end up destroyed before episode's end.
 * Nope, that's Eleven's TARDIS with an archived control room used to allow a "junk TARDIS" on board.
 * How The Doctor could be Killed Off for Real. More than likely the one to die would be the one we haven't seen much of, but it would be a major twist and Mind Screw if it wasn't and the Eleventh Doctor we know and love from Series 5 bites the big one. And how would anyone ever know which of the two was the original? This is something that would eat away at the surviving Doctor, more so if he was in fact the 'off-screen' one (that doesn't even know Amy and Rory).

River Song is a Troper.

 * Spoilers! It had to be said.

The Astronaut in "The Impossible Astronaut" is...

 * River We're supposed to find out who she is this episode, and she told Amy she couldn't try killing the Astronaut before it killed the Doctor because it would mess up the timeline. Also, this ties into the theory that she kills the Doctor.
 * Also, note that she says "of course not" after failing to kill the Astronaut. Maybe she knows that the Doctor's killer survived?
 * Amy's Daughter- Literally seconds after Amy says she's pregnant the Astronaut is revealed to be a little girl. Coincidence? I think not. Of course, this does lead to the question of how Amy's daughter ended up in 1969 America...
 * To add credence to the theory, a picture of Amy holding a baby was in the little girl's room at the orphanage. Of course, this raies all sorts of questions, the primary one being "why is Amy's kid a TIME LORD?!?"
 * It got contaminated by her spending so much time in the TARDIS and actually did end up having "a time head, or something".
 * Rory - the Doctor clearly knew who to expect, and he knows Rory. Also, why not?
 * River Song, who is also Amy and Rory's daughter. - Tying two of the above together. For her alias of River Song, River comes from the founding father's names where the Doctor found her and "Pond/River" relates to each other.
 * And by the end of the adventure, either younger!River has repressed the memory (because of the Silence or because it's all just incredibly scary, or because it's necessary - maybe the Doctor wipes it from her mind) or the entire thing turns out not to have happened in the first place. Or both.
 * This would also explain how they're going to solve the inherent problem in having a character who is supposed to keep getting younger (from the Doctor's perspective) as the series goes on -- regeneration.
 * No it wouldn't.
 * Amy Pond, albeit a much older, bitter version that blames and hates the Doctor for ruining her life. In the original time-line (not seen in the series), things went much worse and in addition to losing Melody, Rory also ended up dying at the hands of his own daughter (the "good man" that River admitted to killing). Having lost everything, Amy despises both the Doctor and River and cut off all ties to both, until the Silence made her an offer to kill him in which she gladly accepted. The Doctor, meanwhile, figured out what was going to happen to him and planned far ahead to rewrite time to prevent Amy's descent into madness (and possibly Rory's death), starting with the Utah letters. Amy then appeared in the astronaut suit and shot him to death, and was in turn fatally wounded by River and soon died after walking back into the lake. This will not happen again, however, though the memories of some events will remain.

In The Impossible Astronaut, that was not the Doctor.
It was all a ploy by The Silence, or some other enemy of the Doctor, to deceive and ultimately alienate his friends. Given Nine and Ten's rather short lifespans, it is very unlikely that Eleven will live for over two hundred years before regenerating into Twelve. It is also possible that it was a plan by a future version of River and the Doctor to actually prevent his 'death' that River remembered happening, and that the 'Doctor' was actually some sort of robot being controlled elsewhere by the real Doctor.
 * Alternatively, that was the Doctor, but at the very end of his life. He is actually not Eleven, but a dying Thirteen disguised as Eleven who resigns himself to his fate, knowing full well that he had to die there. If he is actually over two hundred years older as he claims, it seems more likely that he would have regenerated and not stayed as Eleven the whole time. He *is* surprised that he began regenerating again after being shot, but regardless knew that it was all over (he also was the writer of the letters).
 * For what it's worth, Steven Moffat said in the accompanying Confidential episode that it is the Doctor and he is dead. Make of that what you will.
 * Sadly, it likely means this will be the last season. Apparently, the Doctor will not regenerate before his final demise, meaning the story ends with Matt Smith. Unless this is resolved in the next episode somehow (which will necessarily contain colossal paradoxes), or the Doctor actually disguises himself later in life as #11 for his death, it being his favorite form. Which seems unlikely, given that he begins to regenerate, meaning it wasn't his last life...
 * I would agree that this is the last series, if not for two things. One, that the future!Doctor is at least 200 years older than the present!Doctor, and two, Matt Smith has been signed by the BBC to play the Doctor for five years. So yeah. Another four years of Eleven could mean this storyline will go on a while... Four years is plenty of time to find some way to wiggle the Doctor out of it.
 * Just remember the Arc Words of the whole series: "Time can be rewritten." Especially if it involves reversing the death of a character with as much Plot Armor as The Doctor.
 * It appears as of now that it has to be flesh!Doctor that dies at the beginning of The Impossible Astronaut. Otherwise there would be a causal paradox so bad that not even the Moff could get away with it. It would go like this: Doctor dies; flesh!Doctor continues, taking his place; creates flesh!Doctor, flesh!Doctor goes back in time, dies. But there was never a Doctor to create the flesh!Doctor in the first place, and if the flesh!Doctor died he wouldn't be able to create himself. It's just a ghastly sort of Grandfather Paradox. So he must, before the Monument Valley setup, go back in time, track down flesh!Doctor, and... well, something wibbly-wobbly timey-whimey. It has its problems, but it's better than paradoxes. Also, as confirmed in The Almost People, flesh!Doctor is the Doctor, so Moffat would technically be telling the truth.

River is the TARDIS in Human form

 * Just a wild theory because I think that her being the Doctor's wife/mother/etc. is a bit too obvious...

The Doctor is the astronaut in 2011.
He said, "I know it's you" and "no one interfere" before he died, claiming he knew what was going to happen.
 * It's actually another future Doctor (that is still portrayed by Matt Smith) in the suit, and the TARDIS is at the bottom of the lake. Canton's comment about the Doctor most definitely being dead is both true and a lie... notice that the astronaut seemed to be waiting for him to start regenerating instead of just shooting him multiple times. Yes, the Doctor pulled a variation of the trick that the Master did and transferred his essence / soul into an object on himself (which, for some reason, would only work if he was starting to regenerate), which Canton took off of his body without anybody else noticing, and leaves to the TARDIS where the Doctor has likely set something up to 'regenerate' himself. Everything was planned by the Doctor to trick The Silence, River, Amy and Rory (at least for a while) that he was gone for good, and Canton's letter clearly must have had more information than the other three if he 'knows' for sure about that being the Doctor and that he's most definitely dead. Eventually, he is revived in a new body that looks the same as his old one, and sends the TARDIS to the bottom of the lake... where he exits out of it in the space suit and 'kills' his past self. Also, somehow it is likely that he will have a completely new set of regenerations to get around the 'only has two lives left' thing.

The reason the Doctor died at the lake...
...is because Amy shot the Astronaut. It wanted revenge, and the Doctor didn't want to lose another companion. So, being the self-sacrificing timetraveller he is, he promised the Astronaut that it couldn't kill Amy, but it could kill him. So it all becomes a stable time loop, or as close as they can get to it with the sheer amount of wibbly-wobbly timey-wimey going down.

The Silence aren't malicious, they just don't want people to forget them
Why else would they wear fancy suits if they didn't want people to remember them? The memory erasure is out of their control, but they are desperate to have people both remember them and compliment their appearances. The reason why that one Silent (proper term?) killed that women is that she was constantly forgetting about him, and whenever she looked back, she only commented on his face and never his suit. Eventually he got so frustrated that he killed her, but he regretted it afterward. This is also why he let Amy take a picture of him. The reason why they acted so fearsome in the sewer is because River caught them without any make-up, and a few of them were nude, as I recall. They don't want to be remembered like that. Also note that, as of yet, there is no obvious connection between the killer space suit and the Silence. Besides the woman who was killed out of frustration, there is no evidence that they are being malicious at all.

The Doctor in Series 6 isn't the real Doctor
The Real Doctor is trapped behind the cracks after driving the Pandorica into the TARDIS explosion. The Doctor in Series 6 is the Doctor, but a version "remembered" into existance by Amy. This Doctor is the one who gets killed in "The Impossible Astronaut", and the Astronaut is actually the Real Doctor having got back through the cracks in time. However, since there can't be more than one Doctor in existence at the same time, the Real Doctor has to kill the "remembered" Doctor to stop reality breaking. Again. Elaborating on this theory, all the stuff that happened during the 200 years that the Doctor supposedly spent running was actually him working to free the Real Doctor from the cracks.
 * Alternatively, the real Doctor is still trapped in the Pandorica after the universe was re-created, and Amy 'remembering' him was unable to release him and instead created a new one. He will not be discovered or released until after the Doctor we know dies.

Future!Doctor actually wants to deliberately initiate a paradox
As part of Future!Doctor's Xanatos Gambit to either get rid of the Silence (who may or may not have weaved themselves into the earth/universe via the Time Cracks in Series 5) via a univere-collapsing timey-wimey thing, or to summon the Reapers (from Series 1, in case anyone forgot) to help deal with the problem, as well as to rescue his past self from his eventual death.
 * Which may tie in to how the Silence came to our universe in the first place, who may have caused the cracks in order to discreetly intergrate themselves into events and places within our own universe, and silently (heh heh) conquer it from the inside. (The trailers after "The Impossible Astronaut" seem to support this by stating that the TARDIS team are not fighting an alien invasion, but instead, are leading a revolution, possibly suggesting that the Silence have already suceeded in their world-dominating plans.

Amy's baby is a Timelord.
She got impregnated during "Amy's Choice". The reason she isn't showing is because it was only half a dream, so like Schroedinger's Cat it keeps fading in and out of existence.
 * In "Amy's Choice", Amy was visibly pregnant "five years later". In 2015, there will be an episode that looks a lot like "Amy's Choice", except this time it won't be a dream. Perhaps time lord babies gestate for five years. This ties back to the WMG that Amy leaves the TARDIS due to pregancy, and Smith playing the Doctor for five years.


 * This just got a rather heavy dose of confirmation, as we see the girl who's implied to be Amy's child regenerate. We have also seen the Doctor demonstrate superhuman constitution when he endured the electroshock treatment of the Slitheen, as well as superhuman speed when passing through the fan blades on the space station in The End of The World, so who's to say Time Lords can't manifest superpowers when under stress, which would tie in with the girl dodging the bullet and ripping apart the exoskeleton. However, we also saw that the pregnancy is in flux, whatever meaning that carries...
 * Mostly Jossed, but on the right track. The Schroedinger's Pregnancy is actually due to Amy being a pregnant human piloting a Ganger body (that isn't pregnant). Amy's baby IS a Time Lord, more specifically, a human with Time Lord DNA attached to her.

Amy Pond is God.
Amy is able to reimagine things into being. The Doctor comes when she feels lonely arriving in a police box directly after she prayed to Santa for a Policeman. The Cracks exist because Amy thought the crack in her wall was scary, so she unconsciously imbues it with the power to end the universe. Her parents are gone because when she was young she wished them out of existence. The Doctor was late because Amy doubted he'd come back in just 5 minutes (a young girl's fear of abandonment working against her). He leaves because she doesn't need him anymore, and her doubts the night before her wedding bring him back. The Doctor even implies that she's God when she tries to seduce him after "Flesh and Stone", saying that "The most important thing in the universe is that I get you sorted out right now."
 * If she were God, would The Doctor really say no?
 * He would.

There was a bit of The Doctor buried in the sand where he was shot.
Think Hakarl. The Doctor cuts off a toe and buries it in the sand. When he starts to regenerate after being shot the first time, he funnels the energy into the toe as in Journey's End. The toe starts cooking. After everyone has left, someone capable of surviving a metacrisis, guided by envelope number 5, digs up the toe and grows it into Doctor 11.5.

Canton Delaware fell in love with...
Any of those would explain why an agent in the 60s (or earlier, we don't know exactly when) was fired for wanting to get married.
 * A fellow agent.
 * An agent of one of the FBI's enemies.
 * A man.
 * Confirmed.
 * Someone of a different race. (Inter-racial marriage was illegal in some states until 1967.)
 * Also confirmed. He's black.
 * A woman. However, he's already married, and wants to marry a second woman bigamously. He's a Mormon. That's why the Doctor invited everyone to Utah--Canton lives there, and he didn't want Old!Canton to have to take a long trip.

Amy isn't pregnant.
At first glance, there were clues littered throughout the episode pointing towards Amy being pregnant; her gaining weight, the morning sickness, etc. But at the same time, she never really acted in a way that seemed to indicate that she was actually pregnant; she never seemed worried about how she moved, and whether it would hurt the developing fetus, and in the picnic scene she drank wine. While she did indicate nausea, so did River and Rory after seeing the Silence. Incidentally, the only time she seemed to want to tell the Doctor anything was right after her encounter with them. Which could mean:
 * The Silence wants her to think she's pregnant for some reason. Why? We don't know, but hopefully it'll become clear.
 * It was a defense mechanism on Amy's part. She knows she can't tell the Doctor about his 'death', so her mind tried to fill something in less dangerous but still important to inform the Doctor about. Unconsciously, her mind pieced together nausea + weight gain + something important = pregnant.
 * Furthermore, maybe Future!Doctor's comment about her weight was an attempt to keep the time-loops stable.
 * Jossed. She's pregnant, but there's a Ganger in her place that isn't while Kovarian plots her schemes.

The Silence impregnated Amy with a hybrid baby.
Psychically, of course, probably the first time Amy saw one of them. River and Rory are backups.
 * This would explain the Silent telling her "You will bring the Silence" when she's kidnapped. It looks like the Silence have the proto-TARDIS. Another WMG on this page suggests that the Silence need a human-Time Lord hybrid to fly it - Amy is going to enable that. Alternately, the Silence will use the child to kill the Doctor and get revenge for his attempted genocide.
 * The weird eyepatch lady is a nurse appointed by the Silence to watch over Amy during her pregnancy.
 * Jossed. The pregnancy was natural and through Rory, though the hybrid was tampered with whilst in the womb.

The Silents will meet the Weeping Angels.
And it will be the best staring contest / peek-a-boo game in history!

The Silence are Weeping Angels.
They're way too similar. Angels move through time normally, but only exist in space when someone is looking at them. In the same manner, the Silents always exist in space but only exist in time when people are looking at them. They've also been around since at least the time humans invented fire. According to Blink, the Angels are older than the universe.

We all know that any image of an Angel has the powers of an Angel, ie it will move when you aren't looking at it. Looking away from the image of a Silent, likewise, will cause you to forget the Silent existed.

What if, due to the events of the end of last season, the Angels that got removed from existing in Flesh and Stone came back wrong at the start of reality, with their basic powers flipped? That would mean the title refers to how the Angels began to transform into beings of flesh.

Which leads to my next theory

Every time a Weeping Angel is visible when nobody is looking at them, it's because a Silent was watching them
We just don't remember seeing them. Also, the Silence are apparently responsible for every single time a human ever felt like they weren't alone in a room. Kind of like the sensation of thinking you're being watched.

The Angels Amy had to sneak past with her eyes closed were statues at the time because they thought they were being watched and turned to stone. They didn't start moving when she revealed she was actually blind, they already knew that. The Silence just quit looking at them. And as it's been said before, the time it takes for a television to reload frames is less than the time it takes to blink, so what you saw during Flesh and Stone was what really happens when only the viewer is looking at the Angels.

If you don't think something went horribly wrong with the crack and the Angels, I should point out that the Angel in Amy's mind fell into a crack and got erased. The Pandorica should have revived it and killed her instantly, and yet it didn't, meaning that at least that one Angel no longer exists even after everything that was unhappened by the crack came back to existence.

The Astronaut is BEN
He walked out of a lake. A lake. Like what Ben drowned in. Eleven references the moon shortly before he shows up. The MOON. The Astronaut's identity is concealed by it's visor, which functions as a mask. A MASK. I rest my case.

SCP Foundation-055 is a Silent.
It would explain the Faraday cage, an attempt to contain the Silent’s Shock and Awe powers. It would also explain why document #055-1 theorizes the existence of a conspiracy “to silently observe” a number of the Foundation’s activities. And just how many anti-memes can there be?

The astronaut killing the Doctor is only the suit
River said the suit is capable of self-repair, and has integrated weaponry. We also saw it move, to which River speculates that it may be able to move autonomously, without an occupant, and it seems to have been tied to the girl's mind to function. Thus, when the girl ripped it apart, the last recorded thought was "The spacemen are going to eat me, I have to do something!". Now fast-forward forty-two years, with the Doctor and company having a picnic by the lake. The suit detects a spaceman, and emerges to 'do something'. He shoots the Doctor twice (the bolts emanate from the inside of the wrist, a good position for a concealed energy weapon), triggering a regeneration, but seeing the target is still active, fires a third time, killing it without knowing what needed to be done.

Reason for the Spacesuit
The Silence steal technology from species all over space. The Pandorica was available on earth two thousand years before the Spacesuit, and the Silence have probably got access to most of the species that built it. The Girl is a Time Lord, and is seen regenerating not long after the Silence start being driven back. We can assume the Silence can build life support good enough to keep a Time Lord alive, which means preventing them from regenerating. For whatever reason, they didn't want the Girl to regenerate, at least not until a certain point. They've also been able to program her for plenty of time. The Suit killed the doctor, then killed him again mid-regeneration. For some reason, the Silence really don't like time lords regenerating - maybe regeneration scrambles their programming?

The astronaut suit in "Day of the Moon" had Dalek technology in it.
It's a life support suit with around "twenty different types of alien tech" in it, and it can keep the being inside alive without food or drink. Sounds a lot like the life support capability of the Daleks' armour. I mean, in all likelihood the Silence must have had multiple chances to have come across the Daleks. One of the most likely times they would have had the chance to analyze and steal Dalek tech would've been during "Daleks in Manhattan," especially after Dalek Sec left his armour after becoming a hybrid.

Rory and Amy's relationship has been a fraud from the very beginning, manipulated by the Silence.
While it is very clear that Rory loves Amy, she definitely doesn't seem to show the same devotion. The Silence don't need to influence Rory since his love is genuine, but they have always been around Amy ever since she met the Doctor. However, Rory is also part of their ultimate plan... to eliminate the Doctor.

Subconsciously, she trusts and loves the Doctor more and bits of it slip by that the Silence aren't able to control. In particular, her 'falling out of the sky' speech when taken by the Silence that quite clearly seems to refer to the Doctor... but she was then implanted with a post-hypnotic suggestion to say that she was referring to Rory.

Amy's 'baby' is most likely the unknown Time Lord-girl and was created by the Silence with a Time Lord's DNA, and all memories of it were erased. She was created to pilot their TARDIS- knockoffs (as seen in The Lodger, only a Time Lord-mind is strong enough to do so without killing the pilot). Whether it is the Doctor's DNA or not makes no difference, because Rory would still feel extremely betrayed, especially when he also discovers that Amy doesn't actually love him and considers him to be an inferior shadow to the Doctor.

Due to a combination of being heartbroken, not being the father of Amy's child, remembering nearly 2000 years of an alternate time-line where he protected and watched over her, and dying / being erased from existence / becoming a plastic duplicate and then human again... Rory will simply snap and join the enemies of the Doctor, having nothing else left. He is the astronaut at the beginning of The Impossible Astronaut, finally getting his revenge.

The Future!Doctor's plan is to set in motion a paradox that will prevent both his death and Rory from succumbing too far into The Dark Side to come back, as he did in the original time-line of Future!Doctor.
 * Jossed. Amy is visibly upset about Rory almost dying in "The Curse of the Black Spot" and on a distant asteroid in "A Good Man Goes to War", she talks very highly of Rory to Melody, comparing him in terms of the Doctor.

The creepy face woman is the Dream Lord.
I absolutely refuse to accept that such a creepy villain was nothing more than psychic pollen. No, he's hanging round still, and he's trying to get to Amy. He materialises as the creepy woman - which, for reasons that will be revealed, is somehow meaningful to Amy - whenever she's feeling particularly jumpy. He's also somehow affecting the TARDIS to confuse the pregnancy scanner, as well as Amy's mind on the subject. Maybe the above theory is right about Amy not truly loving Rory, and she's terrified of being linked to him forever with a child. Maybe there's some other reason why he would freak her out this way. I'm not sure how this would all come together, but it's just weird that everything else in the last series was somehow meaningful, and he apparently meant nothing. I think he's definitely behind some weird stuff in this series.
 * Jossed. She's a person peeking through a Ganger chamber which psychically seeps through.

All of series six is another Dream Lord-run collective dream
And the TARDIS crew are in a hospital, asleep. The eyepatch lady is using alien tech to look into the dream and make sure their consciousnesses are doing OK and if they're showing signs of waking.
 * Semi-confirmed. Amy, at least, has been in a dream-like-state, controlling a Ganger during her pregnancy.

The eyepatch lady is....

 * Amy's Midwife. In the Curse of the Black Spot, she says "It's fine. You're doing fine. Just stay calm.", which sounds like what someone would say to another when giving birth.
 * Confirmed! Well, she's there when Amy's about to give birth, so. Creepiest midwife ever though.
 * The Rani. Somehow she escaped the Time War and is trying to rebuild the Time Lord race by using Amy Pond's child as a template.
 * going to kidnap Amy. Or is part of an organization that does the same. Because in the midseason cliffhanger, Rory and the Doctor will go to war to find/save her (that's been leaked), and Eyepatch Lady is the logical choice of kidnapper. Not mutually exclusive with the Midwife theory.
 * The first and third bullet points have been confirmed in The Almost People. Except that Amy was kidnapped a while ago (presumably they never got the right one back from the Silence), and apparently replaced with a Ganger.
 * The Doctor notes it was "before America" when she was kidnapped.

The "House" mentioned in "The Doctor's Wife" trailer is the Ood Brain
As above, they have reason to want revenge on humanity. And there's a scary looking Ood in the trailer...
 * Jossed. It's a sentient creature inhabiting a planet that mind controls several and can work TARDIS matrices.

Amy is in an institution in an alternate timeline.
By remembering at her wedding, Amy brought the Doctor back into existance. However in the timeline before he came back, she continued to insist on his existance. She was eventually institutionalized, and the Eyepatch Woman is her doctor or superviser. Likewise the Pregnant/Not Pregnant effect is due to the alternate world "interfering".

The Time Lords in "The Doctor's Wife" aren't Time Lords at all.
Rather, they're humans who wanted to be like Time Lords and operated on themselves to get two hearts. Of course, they had to get the extra hearts from somewhere... and were exiled to a parallel universe for their heart-stealing.
 * Jossed. They're actually distress signals of Time Lords. All of them are dead now.

Idris is...

 * ...A projection of the TARDIS
 * There's some support for this one.
 * Semi-Confirmed. Not a projections, but literally the TARDIS trapped in a human body.
 * ...A living vortex. Inter-Dimensional Rift In Space
 * ...Romana
 * Jossed.
 * ...River Song
 * Jossed.

The Doctor will build a TARDIS in "The Doctor's Wife"
There is amazing logic behind this. From trailers, teasers and a contest, we know that... So, the scenario: Amy, Rory, and the TARDIS are missing (2). The Doctor is panicked. How to get them back? He has no TARDIS! But wait...he's a genius, in a junkyard(1). He can build a new TARDIS (4), one at least good enough to quickly hunt down the real one, out of the stuff (5) in the junkyard! Idris is naturally skeptical (3).
 * 1.The episode takes place in a junkyard
 * 2,The TARDIS will disappear, with AMY and Rory trapped inside
 * 3.Idris at some point says, "You're like a nine-year-old trying to build a motorbike in his garage!" (or something along those lines)
 * 4.There was a contest to design a new TARDIS console. The winning design, tweaked, will appear in this episode.
 * 5.Released pics of the design show the controls made of really random stuff.
 * Confirmed.

The "wife" referred too in the title of Neil Gaiman episode is the TARDIS
They've been together for a long time. He obviously loves the TARDIS, and given from the trailers it seems to be a large part of the episode. What if the title is actually referring to the TARDIS?
 * Well, it was never stated outright, but I think we can call this confirmed.

The TARDIS exploding wasn't intended to end everything.
From what we've seen of the Silence, they don't seem like omnicidal maniacs. Yet they're responsible for the cracks. Why did they do this? All part of their Xanatos Gambit. They knew the Doctor would save reality, because they were behind it and the Pandorica. The fact that Amy Pond was capable of remembering the Doctor back into existence was an extension of their ultimate plan-to learn and perfect rewriting reality. To become a more powerful force, even gods. Their sudden prescene could be an example of this-before Series Six, they could've been a primitive race. Now,they're manipulating humanity. And in a few more attempts...
 * Alternatively, going on a theory that they're actually good guys,it was a Xanatos Gambit to get the Doc more regenerations, as they believed that being basically recreated out of Amy's memories would set him back as the first, while still preserving his previous incarnations due to the Doctor himself remembering them. And whoever posted above that this had reset his regenerations was a Silent attempting to gain redemption in the eyes of the fans.
 * If the Silence are good guys, they may have altered history so they can be Earth's protection. That way, even in the event of the Doctor's death, the universe will be safe. Or they're one of many individuals who think the Doctor is a threat to the universe. Their Xanatos Gambit would mean the universe wouldn't stay destroyed, and be reset in the end. However the Doctor would be Deader Than Dead, aka Ret-Gone. Everything he's doen to save reality, however, would remain. So the universe remains safe.

"The Doctor's Wife" will feature the return of Patience
She's a Time Lady from the classic series who was the wife of Omega, the Other, and the Doctor in the book The Infinity Doctors.
 * Jossed. All the Time Lords are long since dead.

House from "The Doctor's Wife" is the one behind the Fake TARDIS from The Lodger.
He survived the episode somehow, and his soul escaped to Earth. He had the fake TARDIS built... somehow, so he could possess it and continue his quest to search for more delicious food.

One of the Corsair's regenerations was Dana Scully
That tattoo...

Flesh (from The Rebel Flesh) is based upon Vespene tech.
Because I recall that The Doctor mentioned there being alien technology involved in the process, and the process seems to be akin to that of the Vespene duplicates. It also would explain Rory's empathy, as he remembers being a Vespene duplicate.
 * Don't you mean Nestene? As in Auton-Nestenes? Vespene is sort of a gas....
 * I think Rory would probably be sympathetic anyway; the only real difference between the situation he was in and that of the Gangers is that the original Rory wasn't around when he was an Auton.

Neil Gaiman ships the Doctor with the TARDIS
I defy anyone to watch The Doctor's Wife and not wonder about this.
 * Actually considering the episode's title is "The Doctor's Wife", this is now canon.

The Doctor will team up with the Daleks to stop the Silence
Things will get so bad that the Doctor will be forced to team up with his greatest enemies. It's a common trope, but it will still be neat to see. Plus, it has happened in the old series before. Even if the Daleks still forget the Silence when not looking at them, the Doctor will be able to count on them to shoot them on sight.
 * Apparently disproven. Moff states that no Daleks are in series 6.

The "flesh" technology from The Rebel Flesh is related to Sontaran cloning technology.
The Doctor mentions it's somehow alien in origin and in a season four two-parter (Doctor and Donna travel to earth to answer a distress call from Martha Jones) the Sontarans clone a copy of Martha in a similar looking vat. Also, the brass-looking acid suits are very similar in shape to the general Sontaran suit shape. Rebel Flesh cloning technology is either derived from Sontaran tech or is actually the origin of Sontaran technology. And to be honest, even if this is Jossed, it would have still worked really well as a plot.

Rory and Amy's relationship will get progressively worse as this season goes on.
Somehow, I don't think Amy will be too happy about Rory abandoning her to save another woman who he barely knows and who evidently fancies him. Nor will she be too pleased about him holding hands with her Ganger while they were having the human-Ganger meeting. Sure, from his point of view there's nothing wrong with reassuring and going to save people, but watching his interactions with Ganger!Jennifer and his desperation to find Original!Jennifer makes me think there's going to be some words after all this. From Rory's point of view, Amy's apparent refusal to accept the Gangers as just as human as the Originals, when he himself has experienced being an artificial being with human memories and emotions, must be infuriating. The fact she doesn't believe that the artificial creations can be so human, when one protected her for 2000 years, is actually pretty shocking when you think about it. Rory may not be able to look at Amy the same way after this. Looking at the episodes we've had already, we've had Rory hearing Amy apparently profess her love for the Doctor - sure, it said she was talking about Rory, but "falling out of the sky"? Even as a saying, that doesn't apply to Rory at all! That would imply them appearing out of nowhere, and they've known eachother since they were children. And then her getting at him during Curse of the Black Spot for saying the Siren was the most beautiful creature in the world, while under mind control. Sure, I can imagine her being upset, bu tRory has more than proved his love. And even though it was only a trick by House, there could well have been something in Rory's hate Amy scribbles: after all, House knew about Rory's wait in the first place, so who's to say he didn't get into his mind somehow, and that there wasn't some thread of real feelings in there? As the series goes on, things will just get worse and worse. Amy's constant shock and fear at seeing the eyepatch lady cannot possibly help things. I'm hoping that it will turn out to be part of some plot by some Big Bad, and that the series will end with something happening to remind them how much they love eachother, not with them breaking up or something.

The Flesh is related to the technology used on Gallifrey to create new Time Lords
The Doctor was too freaked out by that goop for it to not have some greater relevance, and he was rather reticent to discuss it. It hasn't just made a copy of the Doctor, it's made a completely functioning Time Lord, with all the regenerative and superhuman powers that would suggest, as well as implying that the Time Lords are (of course) not completely done for.
 * Makes sense. The Time Lords have the DNA of two of them scanned by a loom to create a new one. Perhaps they were modified for the Time War to use one person and create a perfect copy. Someone like, say, The Doctor or The Master bites it, just use their DNA and bring them back. It could explain how they brought The Master back to life for the war, and why The Doctor now has hundreds of regenerations. They got tired of bringing him back. Plus, it seems that it's caused a bit of mental problems in the Gangers (the nicest of the humans became a giant bitch and the giant bitch became the nicest). Perhaps that's what caused the Time Lords to become so evil, the damage from repeated copying. Notice that The Doctor informs them that the Ganger's heart stopped. He was 100% human at that point. So it stands to reason that 11.5 (Goopy?) will end up fully Time Lord.
 * The TARDIS can stablize the Flesh to prevent it from changing back to its goo-y form, which may be Fridge Brilliance it this was true, since it will help newly-born Time Lords to stabilize.
 * Now I think of it, isn't the Doctor supposed to be the perfect genetic reincarnation of one of the first Time Lords? I think it was a novel, so dubious canonically, but if the real Doctor is a copy, what makes Copy Doctor a copy? Oh no now I have a headache.
 * That was the point of the episode. For all intents and purposes, the Gangerdoctor is exactly the same man as the original Doctor in any way. There is no "clone" or "copy" of the Doctor, they are both, at the fundamental level, equal.
 * I made this guess after the first episode, so it still wasn't certain if the Ganger Doctor was a clone or a 'real' Time Lord, but that makes even more sense. What are the chances humans have technology capable of creating whole Time Lords from scratch? That's something only the looms could do. A cheap copy that degrades maybe, but not a proper one.
 * I thought it was scavenged from Sontaran tech. They created a clone Martha who required the actual Martha to be plugged in. Gangers could be a variation of this.

Rory is the titular Good Man who Goes to War in the midseason cliffhanger
Not the Doctor. Not that wild a guess, but I thought it should be out here. The two of them are going to save Amy, which gives Rory even more motivation than the Doctor, and Rory is technically the only "man" involved. Genetically, Time Lords are not human.


 * Related to above, call back to "The Big Bang", with Rory sucker punching the Doctor after the Doctor claimed that his girlfriend isn't more important that the whole universe. Well, she is to him, and Rory the Roman will break the laws of time and space to save Amy, which could possibly have unexpected consequences.

Several of the above are true with a twist.
The Little Girl is a Time Lord (or at least partially).

The Little Girl is Susan, The Doctor's grandaughter.

The Little Girl is Amy and Rory's daughter.

Rory is The Doctor's son. His mother is River.


 * We know nothing about his past, other than he and Amy grew up together.
 * We know nothing about his parents, except that his mom likes Dusty Springfield.
 * He dies a lot, but seems to have a real hard time staying dead. (One of the worst examples of CPR ever in "The Curse of the Black Spot", and he revives afer an awfully long pause.)
 * He's managed to keep 2000 years of experience in his head "behind a door" without going mad. Sophisticated mental trick.
 * He was the one person who picked up on the 'weirdness' in "The Eleventh Hour".
 * He wasn't phased by the "bigger on the inside than the outside"-ness of the TARDIS.
 * He was the one kid who Amy latched onto as her friend. Made his dress up like The Doctor. Family resemblance?
 * Touching on that, the TARDIS thinks Rory is "The Pretty One". More than just looks?
 * Rory can't be River's kid, it's the other way around. That would be squicky and My Own Grandpa.

The Church is going to wage war on the Doctor

 * From the prequel for "A Good Man Goes to War", we see a Nazi-looking fellow with a banner that resembles the ones worn by Father Octavian and his men in "Time of Angels".
 * Evidence here
 * Also, from the way Octavian was acting in "Time of Angels/Flesh and Stone" supports this.
 * Confirmed!

The Doctor will become infamous instead of famous

 * Moffat's been teasing that in "A Good Man Goes To War" the Doctor will lose his reputation. He also says that we'll see a darker side to Eleven. What does this add up to? The Doctor will become so depraved during the war for Amy that he'll be feared, rather than loved, destroying his reputation.
 * Between the Time Lord Victorious, Pandorica incident, and the Harriet Jones scandal I think that boat sailed a long time ago, and may even be deserved.
 * At least among the Church, Confirmed!

Tying in with the two theories above, the universe will start to fear The Doctor...

 * ... not just his enemies (Daleks, Cybermen, The League of Pandorica Evils). The whole Amy ply is a trick by The "Church" to expose the Doctor for who he truly is to everyone, including his allies.
 * Confirmed, as far as Eyepatch Lady definitely thinks she's doing the right thing in trying to stop the Doctor.

River Song is Melody Pond

 * Amy's baby has been revealed as being called Melody Pond. Which it around, and you get Pond Melody. Pond is a type of water, melody is a type of song. She doesn't go to jail for killing someone, she's been imprisoned there and raised in Stormcage since birth.
 * Um, source?
 * Well, this troper can't find any online sources, but most TV-guide magazines in the UK for that week state that Amy's baby is called Melody.
 * Really hope this gets confirmed, great guess man.
 * CONFIRMED!

River kills The Doctor's good side metaphorically during GMGTW.

 * Maybe when she tells him who she really is, it will set off a chain of events that metaphorically kill "the best man she ever knew", because he isn't the same anymore.
 * This would also be acceptable, hoping for a confirmation tomorrow.

The Eleventh Doctor will not raise baby!River... the First Doctor will
He will raise her as a Time Lady, but to help her keep in touch with her human side, he will enroll her in a school in 1963 London under the name Susan.
 * This solution neatly avoids Wife Husbandry, since the Doctor will not know who he is raising.

Amy was taken during The Time of Angels
It could fit the time line. Plus, The Church was in the episode and could have easily kidnapped the real Amy and replaced her before the crisis started.
 * Problem: The baby was conceived onboard the TARDIS and Rory didn't even set foot in there yet
 * Jossed. The doctor explains this is impossible. Rory wasn't there, when Rory shows up he and Amy are having some relationship issues, he dies, then he becomes plastic, and even if Plastic Rory could conceive they were all busy with the universe exploding. The first time they are together as flesh and as a happy couple and in the TARDIS was their wedding night.

The Church is against the Doctor because of the genocide of the Weeping Angels.

 * Wiping out an entire species--even an obviously evil one--is beyond the pale of any religious organization. Not to mention what he's done to the Daleks (repeatedly).
 * Interesting... Especially since the next episode is called Let's kill Hitler! (= Doctor?)
 * I thought it was the genocide of the Silents, who's evil is ambiguous.
 * Teasers have said that Let's Kill Hitler is about "the worst war criminal in the universe...and Hitler." Who killed more people than Hitler? The Doctor!
 * Jossed. What genocide? Either the Weeping Angels never existed (so the non-time travelling Church would have forgotten them), or they're still in the Maze of the Dead. Plus, River keeps meeting the Doctor in the wrong order. I think we can probably assume that "A Good Man Goes to War" is set before "The Time of Angels".
 * Also Jossed, River is the worst war criminal in history because she kills the Doctor in the spacesuit. So at least one organisation still thinks he's a good guy.

The Church is against the Doctor because he is too divine
Think about it... Someone who is only referred to by a title, someone whose legend has spread across the Universe, people fear and love Him... Perhaps even worship?

The real Big Bad has yet to be revealed
The Doctor can't 'beat' in any conventional sense an alliance of people who are convinced they're doing the right thing without cementing their belief that he's the nastiest thing in the universe. But seeing as the series is, you know, Doctor Who, he's got to be the hero eventually or it's just no fun. So, the only way he can win is for something really big, really nasty and really new to show up and threaten absolutely everyone, leaving the Doctor to save everyone yet again, including the alliance against him, and prove that he's not such a bad chap after all. After all, we STILL don't know who blew up the Tardis.
 * My money is on the Church Militant group being manipulated by eyepatch lady (and they will Heel Face Turn in the end, leading to the version of them we saw in the episodes with the Angels), and the Big Bad is whoever is giving Eyepatch Lady, and presumably also the Silence, instructions. I'm guessing its a villain we already know, but knowing Moffat, maybe not.

The Jenny present in "A Good Man Goes To War" is a regenerated version of Jenny from the Doctor's Daughter suffering from retrograde amnesia.
Come on the writer wouldn't reuse a name this significant without some pay off in mind.
 * Madame Vastra penance is to look after Jenny until she can remember her true nature.
 * Of course, Jenny might not have amnesia, and the Doctor might not know who she is. As an adventuring, time-traveling, monster-fighting, kinda sorta Time Lady, Jenny is probably committed to living life on her own terms. She could very well have been poking around Victorian London of her own accord, got caught up in some adventure with the Doctor and Madam Vastra, and decided not to complicate matters by revealing her parentage. Nothing says this won't be confirmed in the future, like if Jenny and Madame Vastra join the Doctor on some adventure, Jenny is fatally wounded, and then starts to regenerate. Surprise!

River's consciousness, still in the Library mainframe, will be downloaded into a new body...
...that of a baby, so that Amy and Rory will be able to actually raise their child. That'll be how Amy, Rory and River depart the series.

The Doctor dies for real in The Impossible Astronaut and River will take his place
As in the previous WMG, the Doctor retrieves River from the Library, but then he goes to get shot by young River. Presumably she is programmed / brainwashed to kill the Doctor and can only be free when he is dead, so Eleven has no choice but to sacrifice himself. Older River inherits the TARDIS and becomes the show's main character.
 * Yeah, I don't think this is likely. I just wrote it down so if it actually happens I can say "Told you so"

The carved Gallifreyan writing on Melody's/the Doctor's cradle said "Hello, Sweetie".
It's the first written words Melody/River sees in her life, and we know she remembers the cradle because she comments on how long it's been since she last saw it. Makes sense those would be the words she always uses to greet the Doctor.
 * As it's the Doctor's cradle, it might be his real name.
 * Or maybe his name is actually Gallifreyan for "Hello Sweetie"...

Life, the Universe and Everything, or "A theory on Series 6 (and a little on 5)"
Okay, so this just came to me, so forgive me if it's a little bit incoherent, I'll tidy it up later. What we know, in no particular order:
 * Eyepatch lady, name forgotten, has kidnapped the little time-tot Melody Pond, AKA the baby River Song.
 * Melody Pond, at some point, lives in an orphanage, from which the Silents steal her away and lock her into a life-support suit.
 * Melody/River is a proto-Time Lady, possessing, at the very least, the ability to regenerate and incredible strength.
 * The Silents possess an attempt at a TARDIS.
 * The attempted TARDIS is seen in "The Lodger", attempting to find a pilot.
 * Eyepatch Lady wants to raise Melody/River as the ultimate in Doctor killing technology.
 * The Silents aren't builders - they tend to tell/command humans and god knows what other species to build their tech for them - it is reasonable to assume that they, themselves, didn't build the attemped TARDIS.
 * The Silents have an unknown agenda, probably not directly linked to Eyepatch Lady's own.
 * Amy will 'bring the silence', presumed at this point to refer to Melody/River.

So, we look at these things, and we begin to piece the puzzle together, in my mind, events are best described in the following order: Eyepatch Lady succeeds in stealing the proto-Time Lady Melody "River Song" Pond, who she hopes will be the best weapon to use against The Doctor. How? Because she can regenerate? Maybe, but I don't think so. Remember in the original series, it was well established that a TARDIS could only be used once it had been activated by a Time Lord, thanks to their symbiotic relationship, and a part of them called the Rassilon Imprimateur, presumeably added by Rassilon himself, but maybe just named after him. Hoping that Melody will be able to activate it, she oversees the construction of the attempted TARDIS. For whatever reason, it doesn't yet get activated, and, again for whatever reason, EPL (Eye Patch Lady) disappears from the picture and Melody winds up in an orphange.

It is at this point that the Silents, having previously captured the attempted TARDIS, discover her and recognise her for what she is. They have her kept safe and sound inside the spacesuit life-support system, presumeably whilst they wait for her to grow old enough to activate the fake TARDIS, maybe to stop her from realising who/what she is, maybe because some part of the suit prevents her from forgetting them, who knows. She escapes them, and it is around this time that slightly younger Amy (or her ganger, at least) is kidnapped by the Silents. They are hoping to find how she was able to grow a Time Lady, or to plant a suggestion into the fetus, or something - I'm still working on it.

Here, The Doctor, an older River and a functional TARDIS arrive within the attempted TARDIS, and begin wreaking havoc. At some point, either The Doctor, River or the actual TARDIS itself, primes the new vehicle, whilst in the process of shooing the Silents away from Earth (Shoo! Shoo! Go on, silents, get! ). The fake TARDIS, now primed and built for River, begins looking for its pilot. Eventually it just wants any pilot, winds up above Craig's flat and gets destroyed by the Doctor in Series 5.

There was more, but I forgot it all. But believe me, it was good. And accurate! Mwahaha!

The Doctor will go to the Gamma Forest and meet a younger version of Lorna
The Doctor will meet Lorna again at the gamma forest where he takes young River to grow up (where she then becomes known as River and decides she likes the name, possibly because it seperates her from being known as "melody" because that was her name while being raised as a weapon against the doctor) Lorna mentioned the Doctor being there was the only eventful thing to happen there and it seemed like her character should of been more important from the focus she got.

Ten and Eleven will never meet in a crossover special.
Ten was reluctant to regenerate, and from what I could tell, he had no idea what kind of man he'd become, making it unlikely that he ever met Eleven.
 * The solution to this? Have Ten forget the whole experience.
 * That, or Eleven never reveals to Ten that he's the next Doctor. He, Rory and Amy just pose as Those Three Guys.
 * Or Ten will meet Eleven via Time Crack remnant, becoming an anomaly. In his perspective, the meeting will have never happened.

If Ten and Eleven ever meet in a crossover special, Ten will not be able to stand Eleven.
Eleven is a little bit more aloof than his previous counterpart, and to someone who doesn't know him well, he can seem kind of heartless. Ten is so reluctant to regenerate because he doesn't want to become what he thinks Eleven is.

If Ten and Eleven ever meet in a crossover special, Ten will be proud of his successor.
The complete opposite of the above idea. While there will almost certainly be some clashing between the regenerations, at some point Ten and Eleven will have a proper heart-to-heart, and Ten will confirm to Eleven that he is happy in who has taken up the mantel. For some of the fans, who were less than happy of the depressing way Ten left, some of the bittness of the regeneration will be wiped away, even if Ten doesn't even remember the incident.

The Silents are trying to save the universe.
From what we've seen, the Silents aren't the cosmic retgonners we've been led to believe. I'm going out of a limb here, and not only saying their benevolent, but actively trying to stop the cracks. They are one of the many species who fear the Doctor, and see him as responsible for the cracks. They have allied with Korvarian, in a misguided attempt to stop the Doctor. The Doctor's genocide of their race is confirmation that they are in the right. Why are they so terrifying? Good Is Not Nice, of course. The Doctor must sort things out, unless the true villain becomes victorious.

River's identity will lead to Amy and Rory leaving.
I highly doubt the two are going to react well after learning their child is going to be raised as a Child Soldier, and ultimately become the proto-Time Lord known as River Song. At the end of Season 6, Amy and Rory will leave the Doctor due to the Fridge Horror-powered trauma that River's identity will create. Similar to how Martha left in order to help her family deal with the trauma the Master inflicted.
 * I'd have to say eventually. But the Doctor is the best chance they have of finding their daughter. They'll only live when they get her back, OR, much more likely, to deal with their trauma after they've given up on ever finding her again (which, of course, will be right before they ACTUALLY get her back).

The Doctor is his own father.
There are various allusions to River Song being the Doctor's lover, mother, or killer. In fact, she's all three. From her personal timeline, she first meets him, then kills him (no doubt to help him, though the reason has yet to be revealed) then marries him, becomes pregnant, and gives birth to him, all while moving steadily backwards in time until she's on Gallifrey 1000 years in the past. Much as the cyclical lessons on proper Tardis piloting, taught to younger River so she can teach earlier versions of the Doctor, River knows his name because he told it to her on their wedding night, and then she gives him the name herself. This is the entire reason the Tardis has been so intent on protecting Earth all this time, because without it there would be no Amy Pond, no Melody Pond/River Song, and hence no Doctor at all.
 * Come to think of it, isn't the Doctor half-human on his mother's side? Or are we pretending that never happened?
 * Pretty sure the "part human on my mother's side" thing is still considered canon. Would make sense.

Amy's parents never existed.
No, I don't mean that her parents were eaten by time cracks. I mean that she never had any parents to begin with. Amy is a living paradox, a Humanoid Abomination who can defy causality. Possibly the masterpiece of Faction Paradox. The Doctor doesn't think that such an entity is possible, so he thinks Amy simply lost her parents to the crack. These "new parents" are simply figments of her imagination made real. She may even be God...

Amy is aware of previous adventures by the Doctor.
In many episodes, its established that there are conspiracy theorists surrrounding the Doctor. Also, ignoring the cracks eating things, the Earth has been invaded a lot since 2005. The invasion by the Sycorax was total confirmation to Amy that she was right. Her general hobby included researching past alien incursions, and the legend of the blue box. She was likely one of the many groups that complained how absurd it is that the government expects people to ignore such incursions. These include a giant asteroid over London, metal men appearing all over the world and shiny spheres vaporizing the President.

Amy was likely a fan of Harold Saxon, because he was against hiding evidence of aliens. Nonethless, she was shocked when she learned he was evil. I almost forgot: Amy S(the S is for sexy) Pond would've had Rory rolepaly as the Raggedy Doctor when he sonicked her. Not to mention construct a sonic screwdriver "toy"]] for personal sonicking.

Predictions for the future of the series.

 * Series Six's theme will be a deconstruction of the Doctor's Memetic Badass statement. Hence the presence of Madame Kovarian. This season's Big Bad isn't the one responsible for the cracks, but those who are actively trying to destroy the Doctor out of fear.
 * At the Series 6 Finale, we will encounter the Impossible Astronaut, right after it killed the Doctor. It will be an earlier form of River, likely a different incarnation. At the end, this version of River will regenerate into a baby, who will raised by Amy and Rory. They will no longer be companions, however they will still be good friends.
 * The Dalek Rangers shall finally get a time to shine in Season 7. They may even square off against Void Daleks. Who will be led by Davros, as a revitilized Renegade-Imperial war.
 * Some of the characters of previous episodes will reappear. For example, Bracewell(in a commentary, Steven Moffat did mention he could be in the year 5 billion for all we know), Vastra (as a badass grandma), and if we're really lucky, Jack Harkness(maybe even a version of him centuries from now).
 * River will become a companion of the Doctor in Series 7, at least for her.
 * Donna Noble will reappear, in order to explain just what the hell happenned to her when the cracks ate the Season 4 finale.

Possible motives for the Doctor's allies in A Good Man Goes To War.

 * Strax was once a famed Sontaran commander. However, he and his platoon ended up getting terribly sick, to the point of near-death. For Sontarans, this is the worst thing that could happen to you. Thankfully the Doctor came along and saved them all from death by illness. While punished by being made a nurse, Strax was spared from a much worse fate. The Doctor helped either in pity, or they were the lesser of two evils.
 * Vastra the Lesbian Silurian owes a debt due to the Doctor saving her group of Silurians, in a Victorian-esque variation of The Hungry Earth and Cold Blood.
 * Dorium almost went bankrupt once, and very nearly lost everything. Thankfully the Doctor came and stopped this. Why? It involves a Vortex Manipulator, a chicken and a whole lot of cargo.

Rory is the Astronaut

 * Think about it: Your marriage has been a result of being hypnotized to love someone and then you have an alien daughter who's part time lord. Your possible threesome tertiary partner is apparently married to your daughter and she makes an explicit sexual reference about him right in front of you. You would want to get something back.

Rory became a nurse(and eventually hopes to be a doctor) for Amy

 * Amy told Rory all about her "Raggedy Doctor" and had him dress up and such, so Rory figured becoming a nurse to get up on the ladder up to becoming a Doctor himself would satisfy her wishes for her Doctor to return. I feel like I've heard it said that nurses wouldn't normally want to change up to being doctors, the reason Rory wanted to in his dream was to be Amy's Doctor(that time because the Doctor had left them be again.)

Alternatively...

Rory became a nurse(and eventually hopes to be a doctor) out of some big respect thing for people's lives

 * It's already been mentioned on this Wiki of the times when Rory, rather than run or fight, would stop and check on injured people, fitting for a nurse but perhaps also a look into his general personality compared to the standard indifferent or horrified reactions some companions would have. However, he also, at least four times, shown a lot of respect for the dead in situations somewhat beyond standard nursing care. In Cold Blood, despite the risk of death or even all out war, Rory insists they return Alaya's body. In The Big Bang, he covers the future Doctor's body with his jacket like a shroud, and earlier seemingly did the same off screen to Amy before going down to free the Doctor, who had uncovered her face when they got back. Finally he pays respect to a dead future Doctor again in The Impossible Astronaut by saying they should "do it right" and do a viking burial, suggesting the original plan was to just roast the body on the beach and throw it in the ocean to keep it from being used. Perhaps this all stems from having a job caring for the sick and needy, but perhaps it's the opposite, and an eventual job as a doctor himself is just a benefit. Funny that he's the one stuck with dying himself all the time.

and lastly, the most important Rory WMG...

The Eleventh Doctor will snog Rory before he leaves as a companion

 * Ten made out with most if not all his companions, to the point of Tennant jokingly regretting that "I didn't get to snog Bernard Cribbins…I- I got to snog all the other ones." Meanwhile, Eleven's gotten a kiss out of both Amy and River, but has only given Rory a loving kiss on the forehead that's easy to miss. The Doctor also seems to have a thing for girls who's names start with R as mentioned in the non-spoilers WMG page, Romana, Rose, River... and then there's Rory. Companion of the most confused for gay/bi Doctor yet... while it might sound like just slash humor and wishful thinking, given Eleven's lack of personal space and such combined with Rule of Funny I still could see a quick kiss on the lips after an important event happening just to complete the trio.
 * Confirmed in the comic, scan here

Jenny "The Doctors' Daughter" will have a very important role in the end of Series 6, or at least the resolution of its Story Arc
Madame Kovarian designed River to be the ultimate Laser Guided Tykebomb in the war against the Doctor: A Time Lord-like being, with the skills of a warrior. Remind you of anyone we know?... She might end up being River's foil and, in a Big Damn Heroes moment and after an epic fight, bring about her Heel Face Turn... Because who wouldn't want to see a fight, and later an alliance, between the two closest things to Time Ladies left in the universe? The Doctor's Daughter and his wife, together? Awesome.

Madame Kovarian has personal reasons for trying to kill the Doctor
It just feels that way. She risked her life for this plan to work but still said the Doctor is a good man (and good men have rules). She hasn't been foiled by the Doctor many times before (in his timeline), so we can assume it's in her future. Adding to that, the reason she didn't just shoot the Doctor or set Demons Run to explode (making sure that she's the only flesh copy left and thus eliminating anything Time Lord-like) is that something he did in his future made all this possible, or gave her her motivation in the first place. The trap is to send him to either find a younger Kovarian and give her that motivation or make all this possible in some other way.

Madame Kovarian is a previous regeneration of River Song.
In this trailer, you can see River dressed up as her very briefly, including the eye patch. Given that River and Kovarian look nothing alike, this obviously isn't a disguise.

Madame Kovarian hates the Doctor with a passion, and for what better reason: She was told that her parents had either abandoned her or were killed because of the Doctor, and wants to destroy him because of it. This also creates a massive Stable Time Loop in which she only knows this by her own future self indoctrinating her, and that in effect River is the Big Bad this season. It's especially painful for the present River because all of it has already happened to her and she can't change a single thing or do much to help.

At some point when Melody is still a little girl, she escapes the Silence and regenerates, and is found by the Doctor. Knowing full well who she is and what she will become, he can do nothing for her and tell her almost nothing about herself and ultimately abandons her again, making her hate him all the more. This is what River was talking about to Rory... the first time she met the Doctor from her own point of view, though by this point her bitterness was gone and she sees that the Doctor truly cared about her.

Somehow, the girl ends up growing up into Madame Kovarian, possibly with more regenerations used along the way. In time, she finds out that her parents are both alive and that what was said to her (ironically, by herself) about the Doctor was a lie, and is betrayed and fatally wounded. She then regenerates into River and willingly submits herself to Stormcage to try and atone for all the hurt she has caused.

Note that Kovarian knows that Amy and Rory are her parents, but at the time of Melody's birth whatever horrible thing that she thought was going to happen to them still hasn't yet. It's possible that she may think that killing the Doctor will save them, for some twisted reason, and her plan can't possibly fail since she experienced it all before when she was younger (she is wrong, of course). So Kovarian wants to kill the Doctor for not having a normal childhood with her parents, which was all her future self's fault by kidnapping and brainwashing her in the first place. Timey-Wimey Ball, indeed.
 * But a weird Viking/Roman thing has an eyepatch... I think it's more a rank. Would fit with the idea that Kovarian is making her Mommy's little assasin.
 * Maybe, but remember that River is supposed to be terrible as evidenced by the Stone Dalek's fear, and her own words at the end of The Big Bang saying how sorry she is for what is going to happen in the Doctor's future. I don't think that her being Melody Pond and the fact she may or may not have been the Impossible Astronaut is enough... what better than if she's actually the Big Bad this season and only half of the 'Who is River Song?' mystery has been revealed?

Faction Paradox will be involved in a Steven Moffat episode.
Because the guy loves his Timey-Wimey Ball.

The Silents exist in Real Life.

 * And only one survived the Doctor's moon landing gambit. It is currently harassing some young adults who just wanted to make a movie.

Madame Kovarian wants to stop the Valeyard

 * She calls the Doctor a good man, yet she wants to kill him, and it's implied that she thinks she's doing the right thing.The Valeyard is bad news incarnate, as He Jests At Scars shows.

Without the skills she learned as a weapon to kill the Doctor, River Song would not have lived very long

 * Others may have been after her for even worse experiments and gotten her instead of Kovarian. Anyway, Time Lord DNA are said to be very sought after by various empires. And even a partial one, like River would have been if she didn't have experiments done to her (by Kovarian or possible others), would be in a lot of danger.
 * In a Torchwood episode, Martha was experimented upon because her immune system mutated from all that travelling in the TARDIS, and she wan't even a companion for that long. So what about Amy and Rory, and all the other companions the Doctor has had over the years? Rose absorbed the Time Vortex and had it for a while, Donna turned part Time Lord and had to had her mind wiped, but still isn't human. What the Hell, Hero?

Melody Pond is a human Time Lady

 * It's been noted multiple times that while their body plans are superficially similar, Gallifreyans are biologically very different from humans. The most obvious feature mentioned is the single/dual heart circulatory systems, though other differences have been mentioned. This means that if Melody's body plan is that of a classic Time Lady, then the Time Vortex is one hell of a targeted mutagen (and allows a human mother to sufficiently provide for a completely alien fetus). A more likely explanation is that Melody is physically similar to a human (e.g. has one heart) with Time Lord-specific characteristics like increased intelligence and regenerative abilities.

Craig has broken up with Sophie
It saddens me to say this but but no one had said ANTHING of her coming back and Sophie is not in the trailer.
 * I think Sophie was seen in filming pictures, and didn't they say they were having a baby?
 * Yes! And I didn’t see any pictures of Sophie and I read on wikia that Craig had a baby but that was under rumors.

The Silence are what Area 51 is covering up.
I say this because in the trailer, I saw a Silent being in a liquid canister.
 * Jossed. A Silent is imprisoned briefly in Area 51. The Silence don't need to be covered up however, as people forget they exist as soon as you turn away.

The Eyepatch of evil
The new coming soon trailers give us River and and an unknown chessplayer character (Celestial toymaker, anyone?) the same eyepatch Madame Kovarian wears. My personal theory is that it acts as a perception filter of some sort, and "forces" a perspective on the wearer to a certain goal/perception, like say, kill the Doctor, or something. I can see how the Silence might either be creating the technology or are actually the source of the item itself.
 * Related to the above, the unknown chessplayer could be an eyepatched Doctor (or Rory?). Would be funny for a "I wear an eyepatch now, eyepatches are cool" line too.
 * Alternately, the eyepatches could be simply eyepatches with a picture of a Silent on the inside, so the wearer always sees the image and never forgets them. That allows the Evil Eyepatch Team to work with the Silents.
 * In A Good Man Goes to War, when the Doctor confronts Kovarian, he seems to give her, or possibly the eyepatch she wears an odd look. Maybe it's some sort of modified perception filter designed to hide something? The old fanboy in me would love Kovarian to be the Rani - apart from liking the character, if there's one person who could develop a Time Lord - human hybrid from a baby conceived in the TARDIS, it would be one of the foremost - and most amoral - biochemists ever produced by Gallifrey.

River Song is the TARDIS
So, despite the heavy Doctor/River shipping that's been happening, Moffat randomly decides to throw in an episode where we see a much longer-lived relationship cast into the limelight? In an episode called The Doctor's Wife? When River has been heavily implied to be just that? It all makes sense now! At some point, the TARDIS comes to life again, as River! Perhaps it was even the Doctor meeting River in the first place that put the idea in her mind.
 * Jossed by both The Doctor's Wife and A Good Man Goes To War. The TARDIS can't be a human. And River Song is Melody Pond.

The doctor won't travel in time for a while, time will come to him
There are 5 daleks in existence, and the doctor knows the TARDIS is kind of broken. If he goes to the future, there is a chance that he won't be able to come back before the daleks craft an empire and exterminate the universe. Thus the doctor won't go through time, but instead follows the daleks. But, you ask, river song was in the previews, how can she appear in the 1940's? The answer, my friends, is that there are cracks in space/time. The whole world with the statues fell through a crack.

Rory's camera phone will continue to be an important plot point.
It was already important in The Eleventh Hour, and a clip from Vampires in Venice shows him taking a picture of Amy in Venice. Perhaps it will be used in order to prove some event happened, after the event gets swallowed and erased by the crack?
 * Rory's camera phone was pivotal in Day of the Moon in proving the existence of the Silence (though not having to do with the crack)

== At some point in the future, dissident members of the subject races of the Human Empire, including the Ood and the Hath, will join together and travel back in time to 20th century Earth to avert the empire's creation. And the Doctor will stop them. == That's why that playback of invaders the Doctor saved the Earth from includes those two. Corollary: If the Doctor hadn't interrupted the playback by stepping through it, it would've shown Twelve and Thirteen.

Time Lords are Egyptian deities
Are you my mummy? Are you my mummy? Are you my--SHUT UP!!!

Dying in the library was a temporary hiccup for River
Come on, we saw in that very episode that the computer everyone was saved on can bring them back into reality, making new bodies with the matter in the air. That's literally the happy ending for everyone else in the episode, they get retrieved from the library's files with their bodies rebuilt like the transporters from Star Trek. The reason everyone who died during the episode didn't get so lucky was because only their minds made it into the computer, not the information of how to build their bodies. But the question is, so what? Sure it can't build a genetically accurate copy of their original body, but it CAN build a human body that looks just like their old one and port them into it. River and the others in the library will all get new bodies, although this probably means River/Melody will lose her Time Lady powers, given a lack of genetic source material to rebuild her Human.Plus! body with. But wait! River has been travelling with the Doctor on and off for a while now, so who's to say he can't just get a strand of River's hair or something for the computer to use. Literally all he has to do is borrow a hair from River, go to the library, give the computer the sample, and River gets her body back AND all her Time Lady powers.
 * Yeah! What the hell! The two Daves, Anita, Evangelista, they ALL had their bodies back, right? No? Oh.....
 * Alternatively; the computer is fully capable of restoring them, but that would mean leaving CAL all alone, and they've already formed a family there.

Let's Kill Hitler will see baby Melody killed off.
I just have a bad feeling, with the preview to the episode, that something has gone, is going or will go wrong. Terribly, terribly wrong. The line "I know she'll grow up to be River" may be foreshadowing to it not being the case...and then the timey wimey ball goes nuts.
 * Who's to say that River is that Melody Pond? Cue her being killed and replaced by an exact duplicate from a second in the past, or something to that effect, just like Harry Kim.

Rose, Martha and Donna will return.
Supposedly, all three are going to be back in some form in the second half of the season. However, out of those three it is only possible for one of them (Martha) to appear, due to Rose being forever in another universe and Donna forever unable to remember the Doctor or she'll die. Some ways to get around this include:
 * A hallucination, hologram or other projection. Quite simply, this is the easiest and most likely possibility.
 * They are from earlier in their own time-lines (but have obviously already met the Doctor), and somehow come to the Doctor's aid. In the case of Rose and Donna, this is probably the only way both of them could ever appear again in the series.
 * Clones, or specifically Gangers created with help from the TARDIS. All three would be aware that they're not the originals, and would have memories up to the point they were last inside the TARDIS (which, in Donna's case, means she'd want to kill him but also thank him at the same time). They'd either all die in a Heroic Sacrifice to save the Doctor, or have to live their lives in another time period of their choice (Rose, because she's legally dead, and the other two have their original selves still about). Either way, they will not be companions for very long.
 * Hold up, where'd you get that "all three are going to be back in some form in the second half of the season" information?
 * They did appear in Let's Kill Hitler but only as options for the Voice Interface's Projected Man.

Madame Kovarian is the Eyepatch.
Specifically it's a powerful AI that controls whoever wears it. The other characters seen with it are in an extended series of bodyjackings.

Faction Paradox is going to show up and attempt to forcibly recruit River
Her entire existence is a series of stable time loops, ripe for creating a massive cascade of paradoxes. How can they not take notice?

The bad guys in The God Complex are the Nimons
Because really, how many minotaur-type alien races can there be?
 * Semi-Confirmed. It's not actually a Nimon, but is stated to be a cousin of their species.

In The Doctor's room in "The God Complex" is... The Doctor
Because really, when he says 'Who else', who could he possibly be referring to?

The Doctor told River his real name...
When he was dying from the poisoned lipstick. When River told him his real name, he told her that there was only one time where he could tell her his name. He could only tell someone his real name if he was dying, with no hope of regeneration. Whatever his name was, it convinced Melody/River to save his life by giving up all of her remaining regenerations.
 * I think he said "I love you", because River responded, "I think she knows", after hearing the Doctor talk about River Song like she was someone really special to him.

The Doctor just screwed Britain.
Take a look at this bit of dialogue from Let's Kill Hitler-

"Hitler: This box...what is it?

Doctor: It's a police telephone box from London, England. That's right, Adolf. The British are coming."

Now, this could possibly lead, once Hitler's let out of the cupboard, to Hitler becoming paranoid and preemptively launching a strike on Britain, causing an alternate timeline where, by that alone, the Nazis won the war. Why would the Doctor not notice? Slow ripple effect, other dimensions and times-he may be too busy to notice.
 * The description for episode 12 has about the episode including an alternate timeline with Churchill, if it was caused by this line then that is clever plotting.
 * ...which didn't feature Churchill at all, only some Cybermen.

Melody ending up in Leadworth was someone in Madam Kovarian's organisation trying to make it up to Amy and Rory.
If they can't raise their daughter, at least they can grow up with her, and they're not the ones it's all aimed at punishing. And her being there isn't exactly necessary to her ultimate mission.

The Doctor has now been replaced with a Ganger.
As of the ending of Night Terrors. When he meets back up with Amy and Rory, he says "It's good to be all back together again, in the flesh." In the Flesh. Since they'd split up, he could have had any amount of time to keep the TARDIS to himself, and then come back to pick them up again.
 * That is brilliant. The line wasn't leftover foreshadowing from the first half of the series-IT WAS INTENTIONAL FORESHADOWING FOR THE REST OF IT.
 * Didn't Word of God say that Night Terrors was 99.99% story arc free. Would a fragment of a sentence qualify for the .01%?
 * To add possible proof to this theory, The Doctor's Wife, the original ninth episode of the season, had Arc Words ADDED to it. Wouldn't it be odd to not REMOVE old foreshadowing?

The Doctor did find toddler Melody/Mels/River.
At the end of 'A Good Man Goes To War', after the revelation of River Song's identity, he immediatly rushed off saying "I know where your baby is!" But at the beginning of 'Let's Kill Hitler' it seems rather clear that he hasn't. Maybe he was lying initially to ease his companions' fears. Maybe he just thought he knew. But he sounded very convinced- so maybe he did indeed find her, but has been lying. This would explain why in the 'Hitler' prelude he looked so very pained at Amy's, and how he and the girl in the space-suit seem to know each other.

Older!Amy from 'The Girl Who Waited' is Madame Kovarian.
We didn't actually see Old!Amy die. We saw her get tranquilised, presumably to go on and be poisoned. But what if she was just taken away? Perhaps through a good dose of time-travel and other weirdness she escaped to start a new life. After 36 years of solitary confinement, her bitterness towards the Doctor reached a climax when he forced her outside the TARDIS. It would explain her vendetta against the Doctor and her interest in Melody/River, who is really her daughter.

The Doctor saw the TARDIS abandoning him in his room
The TARDIS has always been there for him, and now he's learned she always takes him where he needs to go, as well as them being the last relics of the Time Lords, she's the only thing he has faith in. If she left him forever, think about how crushed he'd be.

The Doctor saw himself
Coming from his reaction to the Dream Lord and the way the 10th Doctor went out, can it be anything other than himself, with all his pride, his vanity, the lives that have been lost in his name?
 * I was thinking this, but it raised the question; which and how many versions of himself? Did he see every version? His current self? Or Ten at the height of his madness? There's plenty of guessing to be had here.
 * The Valeyard, it's the Valeyard!
 * I think the room number was Eleven, so presumably it was his own incarnation, though possibly surrendered to his dark side.
 * Maybe it was a mirror.

The Doctor saw the end of the universe
The cloister bell was ringing, of course it's the end of the universe.

What the Doctor saw in his room destroyed his self-confidence
Perhaps the room showed him as the Valeyard or Dream Lord, or some other version of him giving in to his inner darkness, demanding the faith and worship that he now felt was owed to him. Maybe it showed every one of his failures, from his dead and traumatised companions to the entire races and worlds he's destroyed to the countless people he failed to save. Maybe it was simply the destruction of his TARDIS, the loss of the only constant in his lives, the failure to keep the one thing that he feels makes his existence worthwhile. Whatever it was, it destroyed the part of the Doctor that has resisted giving into despair and loneliness, that saw the good that he does and strives to keep going. Combined with the knowledge that his final death is approaching, he has become suicidal and leaves his companions to their lives so he can tie up any loose ends and then go to his death. Which puts his relationship with River Song in a rather chilling perspective - she thinks she's special and that the Doctor loves her, when the Doctor knows he's already failed her, and is just getting all their "dates" out of the way so he can finally die.

The Doctor saw himself, but...
... it wasn't completely surrendered to his dark side, it wasn't the Valeyard. It was only himself. And ONLY him. All left alone, no companions or even the TARDIS. Not even a world to save. Because of two reasons: to make the ending even more heartbreaking, and, after all, what is a Doctor without his patients?

The Doctor saw Amy and Rory (or other companions) dead in the room, or suffering an irreversible Fate Worse Than Death
... which leads him to return them to Earth at the end of that episode so it can't happen.

Earth is the second most invaded planet in the universe
Look at all of Doctor Who, Torchwood and The Sarah Jane Adventures ... I rest my case.
 * Only the second-most invaded planet? What planet could possibly be invaded more?
 * Um... the one that was specifically called the most invaded planet in The God Complex?
 * Apart from the 456 and Cell 115, did Torchwood have that many invasions? Most of it was flotsam and jetsam.

The Doctor's room contained a preview for the next episode.
And his "Who else?" line was a reference to Craig. The thing he fears most is a light-hearted episode coming just before a season finale, because he suffers terribly from Mood Whiplash. That's the real reason he dropped off Amy and Rory - to spare them the cheesiness of him working in a toy store.

The Doctor's room involves River.
Who else? First of all, he's afraid of her killing him, and the fact that he watched her die.

The Doctor's room involved his past companions
Most of them, anyway, if "Death of the Doctor" and "Let's Kill Hitler" are anything to go by.

There are alternate time streams all collapsing into each other, destroying each other as they do so.
That's why the Doctor was eating an apple and solving a Rubik's Cube, and why there's that quote about Holy Roman Emperor Winston Churchill riding his mammoth into Buckingham Senate from the reporter that will be in episode 13. At the end, one or most of the alternate time stream Doctors will be killed by the Astronaut, but the rest of the alternate-Doctors will merge what little is left of each time stream to form one cohesive whole, with only one (living) Doctor.

Amy and Rory's new house is bigger on the inside
.

In the Doctor's room was the Valeyard
In The God Complex, what the Doctor saw in his room was the Valeyard. The thing is, that when he said he was there by mistake, that he had no faith, he was lying. What he does have faith in, is his companions, to keep him from becoming the Valeyard.

Rory will return in most of 11s season finales
Like Jack

The Doctor in "The God Complex" was a fake
He ate an apple. 11 hates apples.

Madam Kovarian is River
The reason she is trying so hard to kill the Doctor, even while calling him a good man, is because she thinks he deserves to finally be allowed to die, as per the minotaur's deaths speech.

The Doctor's adventures from the start of series 6
Will be important later.
 * Maybe the setting of future episodes
 * Maybe a revisit in the series 6 finally

The song
In no particular order
 * Tick-Tock Goes The Clock, And What Now Shall We Play.
 * Tick-Tock Goes The Clock, Now Summer's Gone Away
 * Tick-Tock Goes The Clock, And All The Leaves They Fly
 * Tick-Tock And All Too Soon, Your Love Will Surely Die
 * Tick-Tock Goes The Clock, The Doctor, Brave and Good, He Turned Away From Violence, When He Understood The Falling Of The Silence
 * Tick-Tock Goes The Clock, He Cradled Her And He Rocked Her
 * Tick-Tock Goes The Clock, Till River Kills The Doctor
 * Tick-Tock Goes The Clock, Even For The Doctor
 * Please add what I've missed/change what I've got wrong. And, other than the doctor's death, what could it hint towards?
 * That time will cease to exist with the Doctor's death? "Tick-Tock Goes The Clock, Till River Kills The Doctor." That seems to be what's happening in the next episode, though it doesn't explain why it didn't happen when he died in "The Impossible Astronaut."

Kovarian's eyepatch has a picture of the silence on the inside.
So she can remember them.

Alfie will become a companion.
Maybe not in series 6 or 7, but the writers will definitely come back to him someday.

Steven Moffat has been planning this entire arc since Series 4 of New Who
Evidence:
 * First episode we see River in? SILENCE in the Library.
 * Remember what Ood Sigma said to the Doctor? "Your song is ending" Who kills, ie ends, the Doctor? River Song.

Madame Kovarian is a female regeneration of the Master.
It would explain her obsession with him; maybe the Master went crazy/crazier after John Simm's version regenerated into Frances Barber's version and decided on killing the Doctor instead of flirting with him. She certainly does act a little like the Master's Large Ham self in Closing Time, and the Master's being "a bit hypnotic" could explain how she got the clerics and the Silence on her side. Finally, all that Tick-tock stuff has got to be related to the drumming somehow.

Series 6 will have another Redeemable Dalek
There was the lone Dalek During the 9th's tenure, and 10 had Dalek Sec and Dalek Caan. It takes extreme circumstances, but the Daleks have shown that they can change, that they can break out of their usual thought processes. I think one of the Dalek Rangers will turn on his brothers. He will probably then immediately get killed.
 * Or not. Two words for you: Dalek companion. IMO, the best bet would be Dalek Strategist, as a strategist would probably be more capable of abstract thought, and could figure out the best bet for Dalek survival would be stop making the Doctor mad. Also, IIRC, Strategists are blue, and would go wonderfully with the TARDIS. It could even show it's allegiance with a bow tie!
 * That idea is has more madness in it than all of Sparta. But, it may actually be the most logical conclusion if said Heel Face Turned Dalek dodge the Redemption Equals Death Bullet.
 * Maybe the Doctor picks up this redeemable Dalek and as they travel together they bond a little, and it becomes much better/nicer because of his influence. Then, the day comes when they split up, the Dalek ends up alone on some random planet, and it manages to create a race of nice Daleks, or at least Daleks who don't try to screw with everything they see.
 * The preview for The Wedding of River Song includes a very quick shot of what looks like the Doctor standing by a damaged Dalek at an odd angle that could be a non-hostile moment, maybe these two most ancient of enemies having to team up against the falling of the Silence, an alliance so unpredictable that it's the one thing that even the Silence and its carefully-laid plans can't account for? (Of course, it's far more likely that this is just the Doctor dealing with one more Dalek trying to exterminate him. But you never know...)

The Doctor was doing an alien tribal dance at Amy and Rory's wedding.
Specifically, the Barcelonian Sacred Dance of Joy, traditionally performed at weddings by the family of the bride to bring good luck to the newlyweds.
 * So does this mean the Doctor considers Amy to be family?
 * Well, he is her imaginary friend...

House killed The Rani and/or The Meddling Monk.
It wasn't stated what became of those two in the old series, and considering they were too prominent as enemies to simply be killed off as canon fodder, the House managed to trick them with a distress call and got to them.
 * Why would they answer a distress call?
 * Boredom? The Rani needed new lab rats?

The Big Bad for Series 5 and/or 6 (Seasons 31 and/or 32)...
THE MASTER! Why are they doing it? Because last I checked, Time lords can a ascend to a higher level of existence after nuking the Universe. They conviently left this part out when then manipulated the Enemy Alliance into eliminating the Doctor. Let's realize the implications here. Gallifrey would return as would the Timelords and thus a season long fight against people as smart and powerful as the Doctor who can all time travel starts off. It would be epic! Even though Word of God has said that he wouldn't be bringing the Timelords back, we've heard that before. On first meeting the Doctor, the Doctor is spouting Technobabble at him (why the long accusing look at Jeff?) and rather than say anything along the lines of 'who are you?' he instead says 'You're the Doctor!' and it's the old lady that says 'yes- the raggedy doctor!', so Jeff may recognise him literally as the Doctor rather than Amy's raggedy doctor. Later, we see Jeff on his MΨTH laptop- I have already heard a theory about the psi symbol being associated with Shroedinger which fits some themes in the series (like a cat in a box, cats being known for their curiosity) and of course the Pandorica is most definitely a myth, yet we never see any indication of this MΨTH company again, unusual for a series that puts much emphasis on Bad Wolf, Atmos, and Magpie Electricals. The Doctor says Jeff should get a girlfriend upon seeing what he's been looking at- it's inferred that he's referring to porn, but he may have been hacking or similar as implied by his (IMO) geeky wallpaper. The Doctor tells Jeff to be his 'best man'- a strange way to refer to him, but makes sense if Jeff turns out to be a timelord, especially the Master. It's also logical to assume Jeff was best man at Amy and Rory's wedding, and if the Big Bad is killed at the end of series 6 by River Song then she will have killed a 'best man' in Amy, Rory, and the Doctor's eyes, which also fits in with him being hero to many as he helped spread the 000 virus. Upon leaving Jeff, the Doctor tells him to clear his browsing history- again could be referring to porn, but more likely to refer to the secrets of time travel that have just been shared. Curious, he did not clear his browsing history, and so learned the secrets of time travel. We know that the doctor's method of time travel is through a TARDIS, so presumably it would be this design that got told to the conference, and what do we see later in the series? a TARDIS under construction, in The Lodger. And we can't be forgetting the mystery of the third floor of Amy's house, and her 'living in a house that's too big' for her. A Lodger-esque TARDIS being constructed upstairs? The final piece of the puzzle, the alliance of evil? All converging on the same point in time at the same place, implying time travel? That's right. I can't remember if Jeff's present at the wedding reception, but if he isn't then why wouldn't the best man be there? And if he was, I bet there was a look of surprise on his face when the Doctor turned up...
 * ... is The Joker.
 * Seriously, that voice in the TARDIS sounds a lot like Ledger!Joker. The cracks are images of his smile.
 * ... is Darkseid.
 * Darkseid, realising that the TARDIS is powered by the 'Anti-Life Equation', he forged a plot to destroy the Whoniverse to see if it actually works, abd will then use it in the DC Universe. Well I can't think of anything that much better...
 * ... is Amy's apple.
 * The one with the face, from the first episode. It makes perfect sense:
 * Like the Weeping Angels, its form is its power, and giving it that face somehow gave it sentience (maybe the proximity to the crack had something to do with it). After seeing the Doctor savagely devouring one of its kind, and then daring to declare them all "rubbish", the apple swore to take revenge on the Doctor. When Amelia showed it to the Doctor, the apple used some kind of mind-control to convince the Doctor to take it with him - why else would the Doctor take an apple "for later", when it was established merely minutes before that he HATES APPLES?
 * The apple was in the Doctor's pocket when he examined the crack in Amelia's room, and has traveled in time to 12 years later, so it is aware of the cracks and can remember what they do to people. The apple realizes that the Doctor is afraid of the cracks, and that they may be the key to defeating him, so with a dash of Timey-Wimey, it goes about creating the cracks in the first place and arranging the trap for the Doctor.
 * When the Doctor shows Amy the apple 12 years later, there's a blue flash across the screen. The same blue flash appears at the end of The Pandorica Opens, when the TARDIS explodes (it's a blink-and-you-miss-it, but there are pictures of it somewhere, I'll try to find some). COINCIDENCE?
 * Plus, Steven Moffat has said that the Big Bad is in the first episode, but not the way you'd expect. Jeff hardly seems like the villainous type, and the ducks weren't even there. It must be The Apple.
 * What the hell are you smoking and where can I get some?
 * You say I'm mad now, but you will see. YOU WILL ALL SEE! AHAHAHAHAHAHAHA!!!
 * Myria Le Jean is a zombie with twice as much courage as Human!Ten.
 * ...is Amy.
 * She just doesn't realise it. She's the one causing all the cracks. The evidence all points to the Doctor because she's been travelling with him. Maybe the Dreamlord came from her personality, and the Doctor took the blame because he didn't want to freak her out, or accept that his companion was the one causing all the trouble. Or maybe he can't imagine Amy causing that trouble, so he assumes it was him. Her life makes no sense because she keeps inadvertantly changing it.
 * Or its Auton Rory's soul trapped in Eleven, and his spirit trapped in Amy. Perhaps Rory is a human manifestation of Discworld's Auditors of Reality, and Angel Bob is Edward Cullen.
 * Or maybe someone had already realised this, and the house was a prison, which was why she was all by herself when the Doctor arrived the first time. Since she was only a little girl, whoever was imprisoning her made her believe her life was normal, because even though she was clearly too dangerous to be let loose, they couldn't be totally cruel to her. But something about the Doctor broke part of the imprisonment, and she was able to travel into the village. Once he came back, it completely shattered the restraints on her. Resulting in increased number of cracks.
 * This is why she doesn't remember the Daleks. She's been made to believe she's had a normal life, and there's nothing normal about Daleks, so she can't remember seeing them. The memory of the Doctor is immune to this brainwashing.
 * Actually, it's established that people don't remember the Daleks because of the crack, or at least, it's implied.
 * ...every enemy of the Doctor who didn't show up in "The Pandorica Opens".
 * This includes Omega, The Meddling Monk, The Rani, and because it just wouldn't be a party without him......
 * This may also include Prisoner Zero. His voice resembles the voice in the TARDIS saying "Silence will Fall". Also, he is the first monster to introduce the prophecy of the Pandorica opening. Furthermore, Prisoner Zero may be one of three "Beasts Below". The other "Beasts" are a Starwhale and a rather bothersome central recurring character that can be noticed in "Flesh and Stone" and "The Lodger" (if you look hard enough). All three Beasts Below may have the power to encourage the TARDIS to explode.
 * ..has a base on Mercury.
 * When River opens the TARDIS door right before it explodes in The Pandorica Opens, she sees what looks like a concrete wall. Yet, when we later see the TARDIS exploding, it's in loco Solaris. So she must have been in a position near the sun but inside an artificial prison. Hence, hidden evil Mercury lair. Somebody tell the Doctor.
 * I understood that the concrete wall was actually part of the TARDIS sealing River inside so she could be "safe".
 * ...is Rassilon.
 * Because the 'silence will fall' voice sounds a lot like Timothy Dalton, and he'd have plenty of reason to hate the Doctor. (and I'm going with him being the Dreamlord too, and the Doctor was just lying, because 'it's the evil timelord guy, and we're totally screwed!' isn't something he's going to tell them, even if its true).
 * So, outlandish theory time: the whole Pandorica cracks thing was just a Xanatos Gambit to get the evil league of evil to put The Doctor in the Pandorica so he could use it to reset the universe, because the Doctor remembers Gallifrey, and I'm guessing that's been reset too. (although that does basically assume that part of the resetting is from the doctor's memories, and not just from the atoms left in the pandorica. But I guess it could work either way.)
 * You know that's not that outlandish, in fact it really makes sense! Stranger things have happened on this show.
 * ...is Omega.
 * Omega was the Time Lord who invented Time Travel. It could be his way of trying to fix the broken universe after the Doctor was sealed in the Pandorica, and because of Timey-Wimey Ball, his voice appears at different times as a warning to the Doctor. Omega was trapped into an antimatter universe which he could shape at will (he went thorugh a black hole) and he could have found a way to control our universe, making him the Big Bad. He was directly taking control of the Tardis when it was malfunctioning.
 * ...is the Great Intelligence.
 * Let's see... if you asked me to come up with a formless, immaterial, villain with a sinister, hissing voice whom the Doctor failed to eradicate albeit not without building an enormous enemistude with it, is multidimensional, a genius with machines (even using them as physical links to other dimensions), and originating in the Troughton years from which Moffat draws heavily... one match found.
 * ...built the black TARDIS seen in "The Lodger".
 * It was part of his/her first attempt to Ret-Gone the Universe: make a TARDIS explode, cracking time and space and causing a total event collapse. Unfortunately he/she couldn't get the TARDIS working right, so they moved to plan B: hijack the Doctor's.
 * This troper concurs with your theory. However, it is also possible that the TARDIS herself deliberately built the black Time Engine from "The Lodger". Her motivations for doing so may have been to give Eleven another diversion that encourages the universe to crack, as part of a Xanatos Gambit. She doesn't want to destroy the universe permanently, but she does think Eleven's mind is badly in need of a reboot ( this troper is assuming the Time Cracks and TARDIS Explosion are indicators of Eleven's character development). This is evidenced by the repeated use of the words "start again" in song "Chances" by Athlete. (This song was played at the end of "Vincent and the Doctor").
 * ...is Bilis Manger.
 * Creepy old man? Check. Tried to bring about the end of reality once before? Check. Can travel through time at will? Check. Was stopped by a companion of the doctor? Check. Is still around? Check.
 * Hey, he was one of the few really good things from Torchwood, might as well bring him back.
 * ... is Dave Davenport from Narbonic.
 * He invented a time machine that gets its power by destroying other universes, and he's trying to use Doctor Who's universe for fuel.
 * ...  The Master 
 * He somehow survived The End of Time (not even trying to guess on how.) The reason he's now tring to destroy time itself is becuase he really does want "silence to fall" specificly he wants the drums to finally stop, after so many times of almost dying, almost being free of the constant drumming, the lack of dying, and hence the continuing of the drums, in End of Time were the final straw and now the only thing he cares about is getting them to stop.
 * ...the fez.
 * Come on, like you weren't thinking it.
 * It got mad that Eleven traded it for a Stetson. Like a jealous clingy girlfriend, it returned for revenge. Preemptively.
 * ...The Dream Lord.
 * This would explain the entire plot of Series 5. The Dream Lord represents the impulses of Eleven that cause him to hate himself: The first half of the series portrays Eleven as angry, and the second half portrays him as lustful. If you watch Eleven closely during "The Pandorica Opens", you'll see that the Pandorica unlocks itself every time Eleven gets lustful or angry.
 * Let's not forget that if something can be remembered, it can come back. The whole cracks in the universe thing was a big Xanatos Gambit on the Dream Lord's part to take physical form when Amy remembers him so he can go on to become the Valeyard.
 * That makes a lot of sense, but why go to all that trouble? If the Dream Lord wants to be remembered in physical form, isn't it more efficient to become visible as a physical form to Amy as much as he can? I'm guessing that the Dream Lord may have subconsciously directed Eleven to place the psychic pollen in the TARDIS time rotor. Amy starts to distrust the Doctor when she sees his baser facets (although she grows to find his lust cute in "Vincent and the Doctor".) Are you implying that the actions of the Dream Lord (when not in physical form) are meant to destroy Amy's trust in the Doctor, and make the existence of the Dream Lord seem more legitimate?
 * ...The Doctor himself
 * He's practically a borderline Woobie, Destroyer of Worlds. At some point,part of the Doctor snapped and engineered the whole thing to get rid of the pain he's suffered. The Doctor doesn't know this because its a sub-conscious desire; this has manifested into the Dream Lord, making the above WMG also true. Think about it-who knows more on how the TARDIS works than the Doctor? Series 6 will involve the Doctor trying to fight his inner demons, and the climax will be him regenerating into the 12th Doctor. For good measure,the dark side of the Doctor will split into a physical body-aka the Valeyard. Of course, there's the possibility it's all just a Xanatos Gambit to alter reality enough, so that he can alter history without consequence/go back and stop the Time War/both. Time Lord Victorius and all that...
 * Here's an alternate take on that. Throughout New Who, the Doctor's companions seem to be getting horribly screwed over. This will culminate in Amy and Rory suffering a Fate Worse Than Death, either because the Doctor wasn't clever/quick enough to stop it, or even indirectly because of his actions. This leads to the Doctor undergoing a Freak-Out of massive proportions, going from Woobie, Destroyer of Worlds into a Knight Templar Chaotic Evil Well-Intentioned Extremist for his 12th Regeneration, and then tries to Set Right What Once Went Wrong... EVERY wrong that ever happened or ever will, making the entire universe fit his definition of "right" - sort of becoming a combination of Hao Asakura, Big Brother, Sosuke Aizen, Darkseid, and Sauron. The conflict will revolve around Series/{{Torchwood}, UNIT, Sarah Jane Smith, and all the other Companions from Classic Who trying to stop/redeem the Time Lord Victorious, until he finally gets a Heel Realization and dies, but shunts his evil into a new being (the Valeyard), before finally becoming the Thirteenth Doctor, and the next season after that will feature The Valeyard as the Big Bad, and the Doctor's attempts to put his darkness down for good.
 * ...The TARDIS from The Lodger
 * See the last WMG on this page.
 * ... The Timelord Jeff
 * As has been said, Moffat has said the Big Bad appeared in the first episode but not in the way you'd expect. Whilst this could mean the Atraxi becoming part of the evil alliance, or the TARDIS being the Big Bad, I am convinced it actually refers to Jeff.
 * ... Patrick Moore
 * No-one will see this one coming!


 * ... Fenric
 * How, why, I have no idea. But he's listed on the IMDB page for episode 13 and it hasn't apparently been brought up yet. Granted said page also previously said it was a 3 Doctor story, so take it with a grain of salt. Though, on the other hand, who better to ask the First Question in the Universe, then someone from the Dark Times?
 * It's at least getting more plausible. With a possible eyepatched viking, Churchill making an appearance, and in The God Complex The Doctor was forced to break a companion's faith in the same way as at the end of Fenric's first appearance. If it's not true, it's doing a good job faking it.

The siren from "The Curse of the Black Spot" is the Daughter from the Family of Blood.
The Doctor banished her to hiding in reflections. (presumably through space AND time, this is Doctor Who after all) In her mirror universe (explained by The Doctor in "Black Spot") she had a change of heart and began wanting to heal people (atoning for her past actions?), eventually somehow took on the ghostly appearance seen in "Black Spot" and gained access to the ship she uses in that episode. The ship was modified to be able to jump from her mirror world to sailing ships in the 18th century by manipulation of the largest mirror/reflection available, the ocean.(at least initially until other connections to, say, a barrel of water, a medallion, or a crown could be made nearby)
 * Point being, simply, that "Daughter of Mine" was banished into the world's mirrors, and the siren was able to move through reflections, so there must be a connection there

Theories about what the Doctor saw in his room.

 * The Master
 * Himself. ("Oh, of course it would be you.")
 * Considering the amount of self-loathing Eleven has been shown to have, this one seems most likely.
 * The Dream Lord (who is himself, part of aforementioned self-loathing)
 * The Valeyard
 * The TARDIS, his own personal "Labyrinth"
 * Us. Room 11 has a transparent Fourth Wall.
 * Adric. He spends the rest of the episode convinced that Amy and Rory are going to die if they stay with him. He could have seen their bodies, of course, but then he would have said "What else?" not "Who else?" And what could the Doctor fear more than failing to save his companions?

The Doctor's whispered message in Let's Kill Hitler

 * Was not just a Dying Declaration of Love (that one is obviously implied due to her reaction of "Well I'm sure she knows"). He also tells her his true name (she does not react to this because at this point it does not seem significant). There's only one reason [he'd] tell anyone [his] name, and only one time [he] could." When he's about to die.

Bishop Octavian's clerics who appeared in The Time of Angels/Flesh and Stone are Catholics while Colonel Manton and his clerics are Anglicans.
It would explain why Octavian's men have religious ranks while Col. Manton's have regular military ranks, Anglicanism being (albeit only slightly) more secular than Catholicism. It would also explain, without the timey-wimey stuff, why one group is (apparently) good and the other bad; they're different factions, one supports the Doctor and the other doesn't. Also, just to quote from A Good Man Goes to War, "We're the Thin-Fat Gay Anglican Marines."

The eyepatches allows the person wearing it to remember the Silence somehow
Why else would people be wearing them? They all can't be losing their right eyes. Remembering the Silence's presence would help things tremendously. This would mean the Eyepatch Lady is willingly following their orders, however.
 * I'll repeat a WMG from higher on the page: The eyepatches have an image of the Silence on the inside. If you're always looking at a picture of the Silence, you won't forget.
 * But Theres No Kill Like Overkill.
 * Bizarrely, confirmed. Although it seems to be a bit more high-tech than "picture of the Silence on the inside".

The reason why Time has frozen at 5.02pm on 22 April 2011, the exact time of the Doctor's apparent death is because ...
The TARDIS refuses to allow the doctor to die.
 * No, that's just the time and date of the Fixed Event (the Doctor's death) that was supposed to happen. Without it, it was like a temporal black hole, sucking every other point in history into that exact same moment.

We will not find out who the mystery voice was who took control of the TARDIS....
That will be left unresolved during the season 6 finale and will be saved as the Big Bad for the 50th Anniversary Special.

The Brigadier will rescue the Doctor in the next season.
He's Just Hiding.

River didn't die in The Library

 * She whispered "Look into my eye" to the Doctor. So she gave him the idea to use the Teselecta, after he gave her the idea first.
 * Though it raises the question; if she didn't, then who was that uploaded?

In Series 7 the Doctor will be stealthy
He said himself he needs to go into the shadows.
 * To add to this, he may change the events of Silence in the Library/Forest of the Dead. He would need to avoid being seen by his past self, and the "shadows" could refer to the Vashta Nerada.

Succesfully Breaking a Fixed Point requires a consensus among all currently living Time Lords
How else would The Doctor have been able to do it to save Adelaide (briefly) without consequence, yet River, who's also a Time Lord, shatter time apart when she tried to do the same to save the Doctor?
 * I prefer to think of as a fixed point in time as a train barreling down the tracks. Normally you can change small things. Maybe convince a person or two to get off. Maybe paint it red instead of black. You can try to anchor it, but it resists attempts to change as seen in Waters of Mars. Note what happened with the Doctor, he wasn't able to change things until Adelaide activated the self-destruct. To push her that far the water zombies needed to start taking over. The fixed point was Adelaide being a hero in destroying the Water Zombies and blowing up Mars base. Compared to that having survivors or Adelaide living or committing suicide were minor details.

The Silence got sloppy. They set things up so the Doctor had to be shot and thought dead. They allowed many loopholes around it. River derailed the train by discharging all of her weapon energy. Had the Doctor forcibly saved Adelaide and the crew before a threat was clear or the self destruct sequence occurred, it would have likely resulted in the same thing River experienced.

River doesn't have enough Time Lord DNA to have all their abilities
She just isn't Time Lord enough to defy Fixed Points like the Time Lord Victorious.
 * Or else the Doctor dying is a bigger more important event.
 * It depends on how fixed the fixed point is. Pompeii must explode, but was it always due to aliens? As for Adelei, the Doctor himself states the loophole. The fixed point was strongly tied to her death, but just as a precursor to her granddaughter being inspired and the destruction of the water zombies. Most of the fixed points were also mortals. The Doctor's "death" was unique in several ways. First, it was focused on the Doctor, a Time Lord, not a normal mortal. Second, it was done by a Time Lady of sorts. Again, more time sensitive than a normal mortal. Third, there was a reason the space suit was used. River being a Time Lady (effectively), in a remote controlled space suit with all sorts of alien tech designed to kill the Doctor, all plotted to get the Doctor to a still point in time to craft/make a fixed point. The fixed point, them all to a degree, are mouse traps that have to spring. River tried catching the trap's hammer. The Doctor, Victorious, has learned to use a stick to trigger and walk away with the cheese.

The Universe just likes the Doctor.
The "You owe me" at the end of End of Time wasn't just a metaphor. Causality likes the Doctor, and does it's best to balance out fixed points and paradoxes for him. But this one was just too big for even it to make sense of.

The next multi-Doctor special will take place on River's birthday.

 * "Two Doctors? No, that's a whole different birthday."
 * OH YES!

River has done something much worse than killing the Doctor.
I would like to know why she made a Dalek beg for mercy. Now we know she was a psychopath raised by Kovarian and the Silence trained to kill the Doctor and she would kill the Teselecta Doctor. But why would a Dalek beg for mercy from the one who killed their greatest enemy? They're not even that scared of him.
 * But how many millions, billions, trillions, or probably many more Daleks has the Doctor killed? The best any Dalek has done (to my knowledge) is almost force 10 to regenerate. So if someone who killed your devil wanted you dead, wouldn't you be begging for mercy?
 * But surely the Daleks would be grateful that the Doctor is now dead. The Doctor killed millions of Daleks, yes, and River has killed the man that killed so many before them. So why would killing the Oncoming Storm be a terrifying thing? They want the Doctor dead too.
 * Because the combined forces of all the Daleks have never even come close. Furthermore, the Daleks probably have broken records of the atrocities the Silence have committed in their mission. Even if you're the most powerful force in the universe, you'd probably be afraid of a mysterious force which wants you dead and killed the Devil himself.
 * I figure the Daleks tried to recruit her to some Anti-Doctor League, and the beat the crap out of them.

The Doctor will be a father soon.
Season 6 as a whole had plenty of parenthood themes, with Melody Pond and all. Then 6b had two episodes which were particularly strong on fatherhood - "Night Terrors" and "Closing Time". And the Doctor is now married. Just imagine what happens when Amy finds out she's a grandmother - she had enough trouble with being the Doctor's mother-in-law.
 * 1) Season 6 happened ages ago, we've just watched Season 32. 2) She's already a great-grandmother, Susan does still exist.

Amy and Rory are going to die.
Based on what Karen Gillan has said: "“I don’t want Amy to pop up again every so often, because for me it would take away from the big, emotional goodbye.” She adds: “…Steven Moffat wants it as well. When Amy actually, properly leaves, we both really want it to be for good.” Pondering whether this could mean that Amy would be killed off, the actress comments: “I think it could be done, if you tackled it right… death could be an option.”"


 * 1) If Amy gets killed off for good, then there's no way Rory is going to survive that. 2) What better way for Moffat to make the fandom want to brutally murder him?]

River Song really is Susan.
Moffat has said that we still don't know anything about the truth of River, and that he has something massive planned for the 50th anniversary. A reveal like this would both wrap up River's mysteries, and provide a tie between the anniversary and the beginnings of the series.
 * But wait. The Doctor KISSED her. And they kind of get married. Squick. So maybe River is somehow related to her. Enough to be shocking and wrap everything up. But not enaugh as to be you know incest.
 * But what if the doctor is his own father? Stable time loop.

The Doctor's answer to the Ultimate Question will be...
"Doctor Me!" The following day Stephen Moffat will be found strung up in front of the BBC headquarters as a warning for future scriptwriters.

Gallifrey will return
Not with the time lords, at least not at first, but it will return

In 2013, the Doctor shall come back.
What better way is there to honor the show's fiftieth year than to tie up one of the most famous loose ends in TV history?

The 2012 Christmas special will be based on...

 * How the Grinch Stole Christmas.
 * That could work, actually. The cybermen have left conversion kits under everyone's tree, no one knows which ones they are and The Doctor only has one night to find them all...

If there's an anniversary series, what would the episodes be?

 * Several Who staff have stated that they want a whole series - that's about 10 stories, 7 singles and 3 two-parters. Anything you'd like to see? I have a Colin Baker theme, since he was so much What Could Have Been.
 * Dalek episode from Revelation of the Daleks
 * Cybermen episode from Attack of the Cybermen
 * Vervoid episode from Terror of the Vervoids
 * Celestial Toymaker from The Nightmare Fair
 * Auton episode from Yellow Fever and How To Cure It
 * Sontaran episode from A Fix With Sontarans
 * Epic beginning from The Twin Dilemma (with a story arc akin to Day of the Moon) (two parter)
 * Epic closer from Trial of a Time Lord, especially The Ultimate Foe (two parter)
 * Ice Warriors from Mission to Magnus (Zygons occupied this spot for a while, but they don't have such a mega fan base - I wouldn't mind seeing them though...)
 * Mechanoids from... Okay, I got nothing. Vengeance on Varos would be nice as an inspiration, as would Timelash and The Children of January. Considering these guys haven't been seen since The Chase and some spinoffs, most notably a Tom Baker era annual, we really need more Mechanoids. (two parter)
 * Four companions, and a new (male) Doctor inspired by Colin Baker in costume and personality. I wouldn't really care if it was like Amy, Rory and River with someone like Canton or The Brig in the last spot. Okay, I know people moaned about Adric, Nyssa and Tegan, but they seem to like the new companions.

Season 6's big bad is anti-Silence
The doctor said the silence are an empire, so "the Silence will fall" means their empire will fall maybe unleashing a Sealed Evil in a Can in the form of season 5& 6's Big Bad
 * Or the big bad is the Silence. When you say that Silence falls, it doesn't mean Silence is gone, but the opposite.
 * Eh? Empire? He said no such thing. The Silence is both a religious order (and series 6's Big Bad) as well as an abstract term implied to mean their downfall, the Doctor's death, or a bit of both.

The Empire of Silence probably covers planets other than Earth
Did anybody notice how other species talked about the Silence and how they were fearful of them? It could be that they are stranded dominators on Earth. Also, the only reason the other species are able to remember that they ran from the Silence is because the Silence haven't learned how to make them forget and manipulate them or it only works on certain species that includes Humans. Though I wonder what was so terrifying about them? They didn't really do much to Earth.

The company in The Rebel Flesh works for the Sontaran Empire
Think about this for a moment: Sontarans reproduce exclusively via cloning, they cloned Martha Jones in a manner very similar to The Flesh, and those Anti-Acid suits look an awful lot like a Sontaran Battle-Suit...

River Song is an older Amy. Rory is the 12th Doctor.
The Doctor and River meet each other in reverse order, with the exception of a few incidents (The second last time River ever saw the Doctor was clearly not his second time meeting her). As Amy gets older and River gets younger (from our perspective), they will gradually come to look exactly alike, revealing River to be Amy from the future. Around that time, Eleven will regenerate, and become Rory, who is actually the 12th Doctor. Therefore, The Doctor and River's relationship aren't just backwards relative to each other, but doubled back on itself into a ridiculously complicated Stable Time Loop.

This handily explains why Amy's daughter is able to regenerate. Also makes for some clever Foreshadowing when River tells Rory about when she met the Doctor. From Rory/Twelve's own perspective, it happened not too long ago, and he's just now realizing what effect it had on her. That's why he looks so upset.
 * Jossed, at least in part: River Song, aka Melody Pond, is Amy and Rory's daughter.

The Last Centurion will go on to found an Empire.
Specifically, the New Roman Empire mentioned in "The End of the World." This theory isn't mine but an idea of a poster called Necron Lord from this forum.
 * Hello bricky.

It was River who...
killed The Doctor (or whoever it may actually have been) in "The Impossible Astronaut. Seems likely. She's Amy and Rory's daughter and after firing at the astronaut, she says, "Of course...". Seems like she knows why it didn't drop dead at the very least.
 * Confirmed. Sort of.

The army in A Good Man Goes to War are actually lead by the Silence
The Silence, hundreds of years after the Doctor turned all sentient life against them, attempted to do the same to him, sending subtle psychological hints that he is a great warrior. The headless monks are the only ones who sense their presence, since they do not "see" the way normal people see. However since they do not support the army, they only host them, they do not reveal this secret.
 * It follows that eyepatch lady is either in on their secret, being more directly manipulated than the others, or is otherwise more deeply connected to the Silence than the rest of the church.
 * At the very least, the Silents are allied with Madame Kovarian. Going by the interpetation that they aren't responsible for the TARDIS exploding, this is pretty likely. The Silents have a good reason to hate the Doctor, and could see him as a menace. Plus they were looking after Melody/River as a child, so it's not a stretch to say they're part of the Anti-Doctor movement.
 * Is this even WMG? I thought that was all but said.

== Series Six will deconstruct Davies' habit of not knowing when to quit with his pet characters by having River turn out to be Not A Nice Person, Period, or perhaps just an especially persistent admirer of the Doctor's. ==

The Doctor will eventually have to reboot the Randomiser just so she'll go away and people will stop talking about her, already.
 * She's already untrustworthy, a Child Soldier and very likely killed the Doctor. Take what you will from that.
 * Plus she would have risked the whole of time and space just for him. The Doctor wasn't amused.
 * She's both insane and sociopathic, but still derided by some as a Creator's Pet and Canon Sue. Take from that what you will.


 * I see where you're going. There are also many parallels in term of character.
 * Rory and Mickey are both the main companion's boyfriend, and looked down on. While Mickey remains looked down on and loses his girlfriend, Rory became total awesomeness and gets married to his girlfriend.
 * Amy and Rose both can be jackasses to their boyfriends, and have a crush on the Doctor. While Rose chooses the Doctor and gets away with her treatement to Mickey, Amy chooses Rory, well, mostly and gets a lesson.
 * The Ninth Doctor quickly falls for Rose Tyler, however the Eleventh Doctor was repusled by Amy's attempt at "Glad to Be Alive" Sex, later trying to fix her and Rory's relationship. All three of them treat their male companion as the Nose, but 11 still likes the guy. Both are prime examples of The Woobie, however 10 over-indulges while 11 hides it. And they both have a plethora of horny fangirls.
 * I see some Mickey-Rory parallels, but not enough to call Rory a Take That to a writer and showrunner that MOFFAT LIKES. It was mostly Nine that derided Mickey. Who invited him onto the TARDIS again?

William Shakespeare has been trying to warn the Doctor about the Silence ever since they met
The Bard can't remember that he's seen the Silence, of course, but they affect his subconsciousness so deeply that he drafts Hamlet, a play about a prince who repeatedly uses trickery over actual violence, fighting an evil usurper who gains his power by pouring poison in people's ears. Then he feigns a wrist injury and asks the Doctor to transcribe the play's first draft (as mentioned in City of Death) so that he'll pay particular attention to it.

The rest is Silence.

River Song's Fate will be retconned
The doctor had said he rebooted the universe with Big Bang number 2. Who's to say he wasn't Crazy Prepare and while setting up Amy to bring him back he also set things up to save River from her death. This will lead to him meeting the adult River again after meeting the young River for the first/last time thus ensuring himself some kind of happiness.
 * Didn't he already set things up to save River by giving her the sonic?
 * Not if that River was a fake acting on orders from the Doctor and River herself

The Silence are Time Lords
Except they are Time Lords who have mutated as a result of a failed regeneration. Alternatively a dalek and a time lord got along too well at some point before the time war.
 * A cross between the Daleks and the Time Lords showed up in Evolution of the Daleks, and was nothing like them. In any case, the Silence have shown no regenerative ability and no time travel, which the Time Lords have, but plenty of energy manipulation, inherent memory manipulation and hypnotic suggestion, which the Time Lords don't.
 * However, the Time Lords DO have limited psychic abilities, which The Silence may have put to use. And they wouldn't necessarily have regenerative abilities if they were created as part of a failed regeneration, and they wouldn't have time travel because they'd have been cast out by Time Lord society. As to their inherent ability to see through time, that may well help with the memory manipulation.

== The Silence in the Library episode's title will be very much accurate, and will be revisited at some point == Not only did Moffat use this episode to introduce (and say goodbye to) River Song as well as intentionally foreshadow some of the themes of series 5 and possibly 6, the episode will turn out to have featured the Silence in a crucial role in the events(or there on a different purpose which will become apparent later) and were using their suggestion powers to manipulate the plot and ensure River Song died. The Eleventh Doctor will eventually return there due to the ongoing storyline of River being a new Time lord, and either rescue her consciousness after the tenth doctor and Donna leave(the flesh comes to mind here as a way of facilitating her return), or possibly even go back on his own time-line to save her, leading to a team up with the tenth doctor (and possibly Donna) against the Silence.


 * This will require a reason for the Vashta Nerada to turn up their nano-noses at Silence flesh.
 * And a reason for the Silents not to show up on the scans.

The Eleventh Doctor's companion(s) for Season 7 will be....

 * Rory and Amy. They'll stay on permanently for another full season.
 * Jossed. Though they are joining for some of the series.
 * Just Amy; Rory will either die permanently, or get sick of the TARDIS and leave.
 * So far as I can tell, jossed.
 * Not Amy and Rory. After the revelation that River Song is their child they will be terrified at what their life can do for the ones they love, and try to prevent anything like that again. Or, if Moffat wants to be depressing, he'll go for the death route.
 * ........the revelation from the MIDDLE of series 6? Also, they're confirmed for at least part of series 7.
 * River Song. After having her show up as a supporting character for three season, Moffat will make her a full time companion so we can finally get a better handle on who she is. Making her a constant addition will also let him better explore her childhood, especially in regards to her parents.
 * Jossed. Her role isn't stated as of March 2012, but we'd know by now if Alex was signed on full-time.
 * Canton Delaware III. He's becoming incredibly popular after the Impossible Astronaut/ Day of the Moon two-parter, and the plan may change accordingly. Besides, how would he be able to achieve an official relationship with a black man if he stayed in 1969?
 * Jossed.
 * Someone completely new. Companions rarely stay on permanently for more than a season or two, so Season 7 will give us a chance to see what other long-term companions Moffat will bring to our screen.
 * As of March 2012, confirmed. She'll be played by Jenna Louise Coleman. The character is rumored to be named Gemma Ryan, but this is apparently unconfirmed.
 * Rory and Amy for the first half (including second part of the cliffhanger) of Series 7, and leave during a transitional story featuring a new companion.
 * As of March 2012, we know Amy and Rory are leaving before the season's through.
 * Craig Owens. He had quite an adventure with the Doctor, and the makeshift TARDIS was seen again being used by the Silence. On top of that, he knows quite a bit about the Doctor, considering the telepathic headbutts.
 * Jossed.
 * Just Rory: There's starting to be something of a backlash against Amy in the fandom, while Rory has already managed to achieve Memetic Badass status. However, as she's important to his character, this may happen by having Amy get kidnapped (again) and have Rory continue to travel with The Doctor in hopes of rescuing her.
 * So far as I can tell, jossed.
 * It's going to be Alfie Owens, Craig and Sophie's baby.
 * Jossed.

Madame Kovarian's eye patch has a picture of a Silent on it.
So she doesn't forget.
 * Partially confirmed. The patches do stop them from forgetting the Silence, but in a different way.

Room 11 in The God Complex
Contains the Doctor. Or rather the Valeyard. "Who else" makes it clear he's a person, and his alternately messianic and guilt-wracked personality makes it quite likely that what he is most afraid of is himself.

The Doctor's room in The God Complex contains his most feared and powerful nemesis:
The one person with more power than the universe itself, the one person that caused him more misery than anyone in all time and space, the one person with full reign over his every move: Steven Moffat.

A 50th anniversary celebration episode will have The Doctor retrieving the lost episodes of Doctor Who or Professor X
Admit it, it would be awesome.

The 50th aniversary celebration will be an entire series, with half the series being a crossover... with Inspector Spacetime.
The Doctor's new companion will be introduced at the half-way point, where it will be revealed that she is also a companion of the eleventh Inspector, and existing simultaniously in both situations. The multiverse will take one look at the situation, say "Oh, fuck it" and merge the two universes into one. The rest of the series will revolve around the Doctor and the Inspector teaming up with each other (and their past selves) to prevent the universe from completely collapsing in on itself. They'll also receive help from Canton, and Amy's friend Jeff, who have spent the series travelling around the universe together in a NASA-built time machine, under the orders of Richard Nixon.

Amy and Rory will end up in the Two Streams Facility.
Stephen Moffat and Karen Gillan have been hinting that one of them is going to die. However, that would be very depressing, and while that wouldn't stop Moffat, he might put in something to make it bittersweet instead. So... maybe Amy or Rory is going to contract some kind of horrible disease that kills very fast. Not Chen-7, obviously, but something similarly lethal. But, before they die, the Doctor will manage to arange things so they can check into Two Streams under this disease instead of Chen-7, and therefore not have to worry about being killed by the Handbots. After all, if they've built something like that they'd probably be able to adapt it for different things. Naturally, both Amy and Rory will go in and live out their lives together, while the Doctor watches. Which would still be pretty depressing, but at least the Doctor and the viewers could know that they had full lives together.

So I know this is very unlikely, but still, it could happen.

The Doctor's encounter with the Weeping Angels in New York will be in 1977.
New York is "The City that Never Sleeps", there is always the big bright lights, Broadway, Times Square, etc. July 13th, 1977. The New York City Blackout; the night when the whole city went dark...

also: The Statue of Liberty.

The Ponds exit will involve one of them dying, but thanks to time travel, it will be a bittersweet ending.
Rory will get sent back in time by the Weeping Angels, and the bulk of the episode will cut between Rory in the past trying to get a message to Amy and the Doctor to tell them where he is, and the Doctor and Amy in the present trying to find Rory, and stop the Angels.

Rory's portion will end with him believing he's failed to send a message, at which point he will sit down on a bench, looking sad. the Doctor and Amy's portion will end with them defeating the Angels, and discovering an aged Rory. Rory tells Amy he's so happy to see her again, and that he waited for her. They have a tear filled good bye, and Rory whispers some last words to the Doctor before saying goodbye, and passing away. It's a super sad tearjerker featuring Rory's funeral and all the elements of the tragic ending.

After it's over the Doctor starts up the TARDIS and tells Amy he's taking her home, she argues that with her husband dead, and her daughter gone she has no reason to go home, and might as well stay on the TARDIS for the rest of her days. The Doctor tries to comfort her, telling her that this is a blessing, because they know Rory lives to be very old, and never dies in any alien invasions (with the Doctor commenting that there's been a few between then and now.) Amy asks what good it is knowing he grows old if she can't grow old with him. The Doctor tells her no one ever said she couldn't, and opens the TARDIS doors to reveal that he's brought her back in time to where Rory was sitting on the bench. He tells her about a house, and money waiting for them, or will be waiting once he goes back and sets it up. Amy thanks him and then realizes, since Rory has to live out the rest of his days in this time period, it means neither of them can travel in the TARDIS anymore. She chooses to stick with Rory, and the Doctor says goodbye repeating the stuff from the Big Bang ("you won't need your imaginary friend anymore. Live well, love Rory, etc...) adding that they should avoid messing with history too much. Amy says goodbye, asking that he let River know when they are so she can visit.

Amy departs and soon the Doctor is off on another adventure.
 * Interesting idea, but it won't work because the Angels were wiped from time, remember?
 * Actually, it has been confirmed that the weeping angels will return in episode 5.
