Star Trek: Deep Space Nine/Tear Jerker

"Sisko: So... I lied. I cheated. I bribed men to cover the crimes of other men. I am an accessory to murder. But the most damning thing of all... I think I can live with it. And if I had to do it all over again, I would. Garak was right about one thing, a guilty conscience is a small price to pay for the safety of the Alpha Quadrant. So I will learn to live with it. Because I can live with it. I can live with it..."
 * Tear Jerker: "The Visitor" is possibly the saddest thing on television that doesn't involve Fry's dog.
 * And let's not forget the end of "Duet".
 * The final monologue to "In the Pale Moonlight" sprung tears, perhaps Manly Tears.

"Lieutenant: We've got to go now, sir!
 * Suffice it to say that if Deep Space Nine wants you to cry, you will cry.
 * An unusual entry, I know, but, Nog's true reasons for wanting to join Starfleet always made me feel absolutely awful. The look on Captain Sisko's face throughout made it even worse; he almost looked ashamed of himself.
 * Oh he's utterly ashamed of himself- from the start he'd never considered Nog's request to join Starfleet as anything other than some devious Ferengi scheme for profit and in this scene he virtually bullies Nog into explaining himself, even physically grabbing and shaking him. Then he finds out that Nog's reasons are heartbreakingly personal and tragic and he realizes he's forced the young man to admit that his own father (whom Nog still loves dearly) is a failure because of his own cultural and racial prejudices. Fortunately, he does make it up to Nog.
 * It's also Hilarious in Hindsight, considering that Nog's failure of a father becomes the Grand Nagus and leads a successful top-down revolution of the way Ferengi do business.
 * Time's Orphan, 8-year old girl stranded, alone, 300 years in the past. Brought back as a feral girl 10 years (relative to her) later. Eventually, her parents have to send her BACK as her only shot at being happy. Sorry chief, looks like being The Woobie runs in the family.
 * This one ends up inverted though. Feral-Molly ends up arriving in the past mere minutes after her younger self and ends up performing a Heroic Sacrifice to send the little girl home, choosing to negate her own existence in the process. So it's a happy ending, but still tear jerking on behalf of Feral Molly.
 * That only added to the tears. Would list all the things that add to the tears but that turned into a synopsis (minus the Kirayoshi subplot). This troper would put this episode on a Tear Jerker level with Jurassic Bark (if not higher). After watching it had to go back to the Ferengi episode just prior to stop sniffling.
 * Hell, the first episode starts with a Tear Jerker as Sisko is dragged kicking and screaming from his wife's half-buried body.

Sisko: Dammit, we just can't leave her here!"

"Jennifer Prophet: It is not linear.
 * And later when Sisko meets the Prophets and has to confront his own refusal to move on because he doesn't know how to live without her:

Sisko: [sobs] No. It's not linear."

"Sisko: Do you really want to give up your life for 'the order of things'?
 * Weyoun... poor, poor Weyoun. Not just his death(s), but his entire existence, really. Particularly the "defective" one who died in Odo's arms after a Heroic Sacrifice. But even the look on one of the regular Weyouns's face when one of his Gods (who would throw away his life in a heartbeat, if she had a heart at all) refers to him as a trustworthy and loyal servant.
 * Remata'Klan's Honor Before Reason death at the end of "Rocks and Shoals":

Remata Klan: It is not my life to give up, Captain-and it never was."


 * There's also "Ties of Blood and Water" and the death of Tekeny Ghemor. Becomes bittersweet when Kira, after initially refusing to speak to him after discovering that he took part in an attack during the Cardassian Occupation (he was nineteen years old and was told that the people he killed were smuggling weapons), chooses to forgive the man who has come to think of her as a daughter and buries him on Bajor beside her real father (whose dying moments she had been unable to face, choosing instead to go out and hunt down the Cardassians who had killed him). She found the strength to stay by Tekeny's side and her description of his final, struggling breaths is heart-wrenching.
 * The episode "Life Support" forces Major Kira to deal with slowly losing the man she loves as he sacrifices himself to complete an important and symbolic peace treaty. He keeps insisting on riskier and experimental medical treatments in order to continue his work, supported by both Kira and the Kai. When the treaty is signed and all the costs and consequences catch up to him, Kira is left with only a last chance to say goodbye and tell him how much she loved him, but it's already too late for him to be able to hear or understand her.
 * "Heart of Stone" is the first episode in which Odo reveals that he has been secretly in love with Kira for years. He confesses this to her when it seems like she's trapped in a deadly situation and she's trying to persuade him to leave her behind. She tells him, "I love you too" and that she felt the same way for some time. This is the crucial mistake that tips Odo off that's an impostor Kira, he knows the real Kira sees him only as a friend and wouldn't be the type of person to lie about it in order to comfort him. Later, when Kira asks how he figured out it wasn't her, he explains that the impostor "said Something She Would Never Say."
 * The thing about this episode that made this troper cry was how Kira was slowly being crushed by the crystal around her, her voice getting more and more choked and panicky, and her heartbreaking attempts to make light of the situation and then, when resigned to death, get Odo to leave her. Odo is completely powerless to help the woman he loves and he looks like his whole world is ending. It's really distressing to watch, even if you know "Kira" is an imposter.
 * Oh god, "Crossfire." All of it. Even if you ship Kira/Shakaar, it's still sad.
 * And how has "Tears of the Prophets" not been mentioned yet. Jadzia's death was easily the saddest sequence in Trek's history. And poor Worf. Even he can't keep a stiff upper-lip about this. His roar at the end to warn the gods is concentrated tear-jerker-ness.
 * Also, "The Quickening". Bashir is trying to find a cure to a seemingly incurable disease which is present in a dormant state in all the people on the planet until the day it "quickens" and leads to their death. Shortly after distributing an antigen he thinks will cure the disease, his volunteers' conditions abruptly worsen and Bashir realises the EM fields from his instruments have severely hastened the progress of the disease. All around him are screaming patients in horrendous pain who beg for euthanasia to end their suffering. They all die except Bashir's first volunteer, who is heavily pregnant, but she has quickened which means her death is soon to come. Bashir stays with her and tries to keep her alive long enough to give birth. She lives just long enough to learn that her baby does not have the disease because the antigen crossed through the placenta and gave the baby immunity.
 * "Children of Time". The last ten minutes.
 * The death of Enabran Tain, who was not only Garak's mentor but also, in "In Purgatory's Shadow".
