Inspector Spacetime/WMG

Captain James Haggard is one of the Infinity Knights
He has chunks missing from his memory, and it's not like identity crises are anything new to him. Maybe he's one of the Infinity Knights disguised as a human with the Camouflage Bend.

Constable Wrigglesworth is a Infinity Knight
He's called the Constable. Hello.

Everyone but Inspector Spacetime is one of the Infinity Knights
His parents lied to him and everything that happened in the Time Wave was a hallucination.
 * Mind = Blown.

Brooke Rhapsody is actually
Okay, she said she wasn't, but maybe she lied?]]

Inspector Spacetime will meet his imitator at some point.
Rory Williams will be the only one able to broker peace between the two.

The Instructor is a later incarnation of Susannah Overseer.
Or was assigned to the Inspector's "case" by the Infinity Knights after Susannah was recalled.

The Instructor was preparing the Inspector for being the Last of His Kind.
She knew that the war with the Blogons was coming, and how it would end.

Inspector Spacetime is a T-- BANG!
Oh my, I appear to have been shot by a sniper. Hold on, I'll try to finish: Inspector Spacetime is a T-- BANG! BANG! Inspector...Spacetime...is a...is a Tim...THUD
 * Wait, would that mean the X7 is his TAR-- *BANG*
 * No, obviously his BOWLER is his TAR-*BANG!*
 * Guys, the bowler is really a fe-BANG BANG BANG*
 * Would that mean that Brooke is a part Tim- *BANG*
 * Gee, this is turning into another Candle Jack. Why can't anyone say Inspector Spacetime is a
 * Hmmmm.. Looks like everyone needs to see the Doc--*BANG*
 * All I was going to say was that a Doc-- BANG BANG *
 * Okay, how about a Dent-BANG BANG BANG * COME ON I WAS GOING TO SAY DENTIST!

The Good Lamb isn't a sheep at all.
Its a wolf in sheep's clothing, fooling us all!


 * And going by that trope, it would be a bad wolf...

This Show isn't Real
It's just a show made up by a sitcom to parody something else... why is everyone looking at me that way? I'm not crazy! I'm not! Really! I'm not! You're the crazy ones! It's fake! Why won't anyone believe me!

The Sergeant is a future series of the Inspector's incarnations, after the Inspector's time as the Indictor.
We know that the Sergeant has been given extra incarnations; it only makes sense that he would have come from an unusual background, namely, the Inspector's court martial over which the Indictor presided. The Inspector never really got out of the court martial, but to avoid a Wibble Wobble Time Thing, he couldn't be given the demotion until the instant he became the Indictor. Once his job as the Indictor was finished, his memories were wiped and he became the Sergeant. The Sergeant instinctively understands that there is a connection between the Inspector and his demotion, or even discovered the link in the Archives of the Infinity Knights, and is futilely attempting to drag himself back up by pulling down on his past self's bootstraps.

The Sergeant is a past series of the Inspector's incarnations, from before the Inspector's time as the Indictor.
It was never really explained when the Indictor came about in the Inspector's personal timeline; "Somewhere between your twelfth and terminal incarnations" could mean he came before the Inspector's first incarnation, considering in just the previous arc ("Return of the Revenge of the Blogons", Episode 4, scene 3) the Isrever delegate referred to meeting the supposed terminal incarnation of the Inspector back in Classic Series 1. Infinity Knights' "terminal incarnations" could be their first or last incarnation. This, of course, means that the Sergeant merely got promoted, possibly as a result of his hypothetical commendation for successfully capturing the Inspector in some future episode.

The dumbing-down of the Seventh Inspector's scripts was done as a mercy.
If the weirdness trajectory of the Sixth Inspector had continued, the show would have been giving people seizures.
