Never Say Goodbye

So, the chances of survival look slim. Maybe there really is no way out. So one of our heroes tries to take a moment to let his or her companions know how much s/he loves them, and what a hell of a ride it's been, etc...

But their companions aren't having any of it. "Whoa, whoa, whoa," they will often say. Maybe because they don't want their loved one to accept death as inevitable, maybe they just find the whole idea of a touching goodbye speech embarrassing and awkward. But in any case they refuse to let the would-be speechifier continue.

But if either one of them really is going to die, the one who cut off the other will often, quite hypocritically really, deliver a speech of his own. Sometimes even immediately.

Anime and Manga

 * In Neon Genesis Evangelion, Shinji finds the tone of Rei's goodbyes so distressing that he begs her, "Don't say goodbye when you leave on a mission. It's too sad."
 * In Japanese, "sayonara" does mean "goodbye" but it generally carries the connotation that you are unlikely to see that person for a long time, if ever. "ja ne" or "ja mata ne" (or some variant) is used for a more friendly "see ya later" sort of connotation, instead. Hence, since Rei uses "sayonara", she seems to be expecting each mission to be her last. Which is pretty sad, actually.

Film

 * Titanic. As the main couple float amid the wreckage of the doomed ship, Rose begins, "I love you, Jack," and he responds, "Don't you do that! Don't you say your goodbyes," - despite immediately launching into a long speech himself about how thankful he is he met her.
 * Prince Caspian, the most recent film. During the break in the duel, Peter starts wondering what would happen if he died in Narnia. He starts to say a goodbye speech, but is stopped when Edmund pushes the armor on his bad arm hard. No speeches that time.
 * In the book, at a similar point, Peter actually does give a brief, if more indirect, farewell speech uninterrupted.

Literature

 * When Amelia Emerson, of Elizabeth Peters' series, and her husband are trapped in the waterlogged heart of a pyramid he begins a speech about 'dying in each other's arms' only to be cut off decisively by his wife. When he complains of this, after they're safe, she replies she never doubted he'd find a way out of their predicament.
 * Played with in The Dresden Files' Turn Coat.
 * In the Warrior Cats series, Fireheart finds after a fire. She starts to tell him something she wants him to hear before she dies, and he stops her, insisting she isn't going to die. She knows she's dying, though, and continues speaking.

Live Action Television
"Andros: If I don't...see you again- Ashley (cuts him off): I will see you again."
 * Supernatural, specifically Dean, likes this one a lot. In Season 1, Sam tries to thank Dean for everything before they try to kill the Big Bad, and Dean cuts him off, complete with "Whoa, whoa," explaining, "Don't say, 'Just in case something happens to you', I don't wanna hear that freaking speech, man. Nobody's dying tonight."
 * At the end of Season 3, with Dean fated to go die and go to hell at midnight, Sam tries some kind of "in case we can't win" speech, which again Dean ignores, this time because it would be "socially awkward". Sure enough he's speechifying himself before long.
 * A variation occurs in Serenity when Kaylee and Simon are saying their goodbyes before facing certain death. When Kaylee realises he's saying he's attracted to her (and more importantly, wants into her pants), she cuts short the farewells with, "To Hell with this. I'm gonna live!"
 * A surprisingly touching version appears in Power Rangers of all things, during the Countdown to Destruction two parter, when Andros prepares to confront the Big Bad and says goodbye to Ashley.


 * The Doctor has at times been reluctant to admit when he's not going to see somebody again. (Granted, he frequently does end up seeing them again anyway, so maybe at this point he's just being Genre Savvy.)
 * Parodied by Not the Nine O'Clock News with the song "Kinda Lingers," where the singer says that he finds it hard to say goodbye, so instead he'll say... "cunnilingus."
 * For years, this troper thought it was her own filthy mind that was super-imposing that over the intended Kinda Lingers. It took a while to realise she wasn't the only one...

Theater
"Officer: Goodbye, Perkins. God, I wish I was going too. Perkins: Goodbye, sir... or is it au revoir? Officer: [glaring at him] No, Perkins."
 * Parodied in Beyond the Fringe's World War II sketch, after an officer orders a soldier to go off and get himself senselessly killed for no other reason than that it will "raise the tone."

Western Animation

 * Happened on the "Max Out" episode of Ben 10 Alien Force, though there wasn't a body, so who knows...
 * Anyone who watched Season 2 and the Grand Finale knows—since it was an uncontrolled Null Void generator, Max got out of the explosion and into the Null Void.
 * The characters of He-Man and the Masters of the Universe, The Movie are always interrupting each other's farewells to say, "Don't say goodbye. Say good journey."
