* The defining ''Lost'' death so far is still [[spoiler:Charlie's. One of the most awesome characters on the show, [[HeroicSacrifice dying to ensure everyone else lived]].]]
** His death is even worse when you know it's coming and you watch him [[spoiler: dive down into the water, and you know there's no turning back...]]
** Hurley's reaction was pretty heartbreaking as well-- when Desmond returns, and he and Sayid and Jin and Bernard all arguing about the message Desmond recieved, and then suddenly [[spoiler: Hurley: "WHERE'S CHARLIE?"]] And everyone goes silent.
*** And then again, when [[spoiler: Hurley told Claire...]]
** What really got me was the fact that even though Desmond knew that [[spoiler:saving Charlie's life again would just disrupt the course of events in his visions and possibly prevent Penny's supposed boat coming to save them, he ''still'' grabs the fire extinguisher and tries desperately to break through the window to get to him.]]
* More recently, [[spoiler: Charlotte]] dying while all [[spoiler: Daniel]] can do is watch.
** Made even worse when [[spoiler:Daniel meets an adorable young Charlotte, and she says what will eventually be her last words. It becomes clear that, as she died, Charlotte regressed back to her meeting with Daniel during her childhood.]]
** How about [[spoiler: Daniel's]] death?! Killed, no less, by [[spoiler: his own mother!]] Who later is forced to send him to the island, KNOWING that [[spoiler: he was going to be shot by her younger self in the past!]]
* Juliet's whole story is really tragic, especially rewatching the series and knowing why she does all the things she does and understanding who she is...and knowing in the end she never gets to go home.
** Especially the flashback where she sees her healthy sister and nephew for the first [[spoiler: and last]] time
** Locke's reaction - just him, pounding at the Hatch, betrayed that what he thought made him special led to Boone's death.
* Also not related to death, when Jin's story is finally told and [[spoiler:it turns out that he's not heartless and uncaring toward his wife, but actually madly in love with her and suffering horrible trials from her father because of it]]
** Then later when Jin finally reconciles with his father, admitting he was ashamed and breaks down.
* "Flashes Before Your Eyes" is one of the all-time biggest tearjerkers. Just the premise- being forced to relive the biggest mistake of your life, ''knowing the whole time that you're powerless to change anything''- is bad enough. But the end features one of the most brutal [[HopeSpot Hope Spots]] in recent memory. [[spoiler: After breaking up with Penny (again) Desmond finally manages to prove to himself that he ''has'' actually travelled back in time. He has one moment of absolute joy, thinking that he actually ''can'' manage to fix things... only to get sent back to the island seconds later.]] His subsequent breakdown when he starts begging for another chance is absolutely gut-wrenching.
* What about the flashback where Michael has to say goodbye to Walt? That definitely had me tearing up.
* I don't like Ana Lucia that much, but I ''bawled'' when [[spoiler: we see the flashback of her crying as she talks to her mom in the phone before taking the flight.]]
** Also Ana and Eko's "You waited 40 days to speak?"/"You waited 40 days to cry" scene always moves me to tears, especially on re-watches, considering that they and Libby [[spoiler: later die, leaving Bernard the only Tailie who didn't die or get abducted.]]
* [[spoiler: "I have to say goodbye to my daughter, John!"]]
* Season 4 finale. [[spoiler: Sun screaming for Lapidus to let Jin on the helicopter. The freighter blows up, and Sun just loses it.]] Oh dear sweet ''God''.
* [[spoiler: Juliet drinking on the beach after the freighter blows up because she once again dared to hope she could go home and once again had to realize the island would never let her go]]
* Most of Locke's flashbacks (even some on-island stuff) are tearjerkery. Especially his first one when that Walkabout told Locke what he can't do because of the big twist that [[spoiler: Locke was a cripple before the crash]]. There's also when Boone dies and Locke loses it on the Hatch, his father conning him for a kidney, he obsession with his father ruining the only relationship he ever had and most recently in Season 5: [[spoiler: How everyone of the O6 ridiculed him AND Helen died to the point where he broke down and was about to commit suicide.]] Dude's had it rough.
** Even more tearjerky when we get Desmond's perspective on the same scene later in the series and learn [[spoiler: that he was, if possible, even more desolate than Locke and that moment saved him from suicide]].
** Jack telling Locke that's he's nothing but a sad, lonely old man. Especially sad because the audience knows there's more truth to Jack's words than he realizes.
* The end of "Some Like It Hoth," with Miles watching through the window as his dad reads to his infant self.
** That scene was especially tear-jerker-iffic because it's when Miles realizes that his father wasn't a heartless man who abandoned him.
* The Season 5 Finale "The Incident" was a crapfest for Juliet and Sawyer as the happy couple broke up and then later when Jack caused the incident, Juliet was sucked down the giant magnetic hole of doom. Sawyer then grabbed her arm in an attempt to save the good doctor, but with the metal chains wrapping all around her lower body all they could do was tell each other they loved them and then Juliet was sucked down the hole with too many sharp metallic objects to count and Sawyer then wept. Then the audience finds out before the end of the show that Juliet is not dead, but very well on her way with blood coming out of her chest, mouth, ear and other places. Dr. Burke sees the undetonated hydrogen bomb lying next to her and then blows it up, with the final quote of "Son of a bitch!"
** Juliet seeing the unstable superstructure above Sawyer's head, telling him that she loved him, and letting go of his hand. Talk about a HeroicSacrifice.
** Worst off is the fact that Juliet had been trapped on the island for ''six years'', and never got to meet her nephew or see her sister again.
* The last scene of "?", a montage, is just dripping with emotion: Hurley sobbing over Libby's body ("I'm sorry I forgot the blankets! I'm sorry!"), Jack feeling completely helpless because he can do nothing to help her, Sawyer and Kate taking their respective guards down and losing it because of Libby and Ana Lucia's deaths, Micheal stewing in self-hatred knowing that he has crossed the line in his effort to rescue Walt, and Locke, utterly disillusioned with his "destiny". In comparison to what they would go through later, it doesn't even seem as bad, but the whole scene, especially the music, is just heartbreaking.
** Hurley in the beginning of "Tricia Tanaka is Dead" talking to Libby: "Everyone is afraid. I'm afraid too. Except when I'm with you. I miss you."
* The scene when Rose and Bernard finally reunite.
* Mr. Eko reciting the 23rd psalm while the plane in which his brother died burns.
* Some of the best parts of the series were at the end of the first season finale, when the survivors, who at this point tended to still snarl at each other every once in awhile, have to say goodbye when the group gets on the raft. It's wonderful.
* Most recently, Sawyer in "What Kate Does".
--->"It's not your fault she's dead... It's mine. She was sitting right there, right where you are now, trying to leave this place, and I convinced her to stay. I made her stay on this island because I didn't want to be alone. You understand that right? But I think some of us are meant to be alone. ...I was gonna ask her to marry me."
* On that note, "Dr. Linus". [[spoiler:Ben is on his way to the Hydra Island and holds Ilana at gunpoint. He tells Ilana that he knows how she feels because he sacrificed Alex for Jacob...then learned that Jacob didn't care about him. He asks to be let go, so he can join Locke. Ilana asks why. He says "He's the only one that will have me". Ilana, who just minutes earlier was making Ben dig his own grave, says "I'll have you" and lets him follow her back to camp.]] And at the same time, [[spoiler:flash-sideways Ben sacrifices power for Alex, succeeding where main Ben failed]].
** It's not nearly as heart-rending as Ben's, but Richard had his moment too.
--->"I devoted my life, longer than you can possibly imagine, in service of a man who told me that everything was happening for a reason; that he had a plan, a plan that I was a part of, and that, when the time was right, he'd share it with me. And now that man's gone, so... Why do I want to die? Because I just found out my entire life had no purpose."
* "Ab Aeterno", most notably [[spoiler:the end between Isabella and Richard]]. There's a reason why it's regarded as the second best episode of the series (in case you're wondering, "The Constant" is the first).
** Pretty much all of ''Ab Aeterno'', actually. Poor Richard's life ''sucked''.
* In "The Candidate" [[spoiler: Sayid, Sun, And Jin]] all die aboard [[spoiler: Widmore's]] submarine. The real tear jerker is the death of the latter characters [[spoiler:Sun and Jin as they die in a Titanic-like scene where Jin desperately struggles to save Sun while she begs for him to leave. Jin ends up dying holding hands with Sun.]] Seriously, look at the Twitter traffic at the moment.
** It's made all the worse when you realize [[spoiler:Sun]] and [[spoiler:Jin]] had only been reunited for a couple of ''hours'', and then that scene comes along...
** Even worse is that [[spoiler: Ji Yeon, the daughter of the two that Jin has never met, is now an orphan]]. I'm worried they will kill the power couple Penny and Desmond next......
** As emotionally wrecking as that scene was, what set me off was [[spoiler: Hurley's heart wrenching sob of pain.]] Just hearing that sound from the most lovable guy on the show sent me into full on sobbing.
** Even more than the deaths themselves, seeing the four on the beach--Jack, Kate, Hurley, and even SAWYER--all start crying when they realize that[[spoiler: Jin, Sun, and Sayid are dead]]...that was the worst part.
* In the final episode "The End" we have [[spoiler: Jack dying on the island. The last thing Jack sees before he dies is the plane containing his friends leaving the island. Walt's dog Vincent lays down by his side as he dies.]] *sniff*
** [[spoiler: The purgatory/flash sideways reunions of Sawyer and Juliet, Charlie and Claire, and Jack and Kate did it for me. Then the ending set in, and tears abound.]]
*** Don't forget [[spoiler: Jin and Sun remembering as they see the ultrasound of Ji Yeon in the hospital...only to have Sawyer come in, and the smiles on their faces as they recognize him...]]
** Don't forget when Hurley [[spoiler: doesn't want to take over from Jack, because it means that Jack's going to die. Also when Jack farewells Desmond for the last time. And when Jack gets soaked by the water from the source, and he's laughing, knowing that he's saved the island. It's not just the "awakening" scenes.]]
** While the GrandFinale is a major [[InnocentInnuendo jerk fest]], certain moments always get me. The first being when Kate and Claire both [[spoiler: remembering after Aaron is born. They're both so happy to be reunited, but sad at the same time because they realize that they're all dead]]. The second being when Sawyer and Juliet [[spoiler: remember when she fell down the ditch and he couldn't pull her back up, forcing Sawyer to grab her in a hug and say "I gotcha, baby. I gotcha."]]
*** Watching the extras of the final season DVD, you get to a part where Jorge Garcia (who plays Hurley) reads the script for the finale and he is left in tears and in a complete loss of words. That is reaaaaly tearjerky!
* Something about the [[spoiler:Jack/Boone]] hug in the church set me off - perhaps because this was the first character that the audience sees die, and the first character that Jack is unable to save. That knowing smile on [[spoiler:Boone's]] face just says it all: that everything's okay now. That everything was ''always'' okay, we just didn't know it.
* Kate and Claire holding hands as the Ajira takes off, and then sharing a smile when they realize that they're in the air and that they're going to make it home.
* In season 5 when Hurley [[spoiler: explains to his mom (and audience) everything that happened on the island, and she basically says "I don't understand, but I believe you," I just tear up every time, taking into account how for the past 3 years, Hurley's lost all his old friends, and has tried and failed to deal with all the trauma on his own, when he had his family with him...man oh man.]]
* A lot of credit for creating Tear Jerkers has to go to composer Creator/MichaelGiacchino. Just try to listen to [[http://www.youtube.com/watch?v=twHXrNtG-7c Life and Death]], [[http://www.youtube.com/watch?v=n2NsTFgWmsQ Parting Words]], [[http://www.youtube.com/watch?v=u8mTmjP-TJ0 There's No Place Like Home]], [[http://www.youtube.com/watch?v=NztoCfmACww LAX]], [[http://www.youtube.com/watch?v=5mOnmsw9Iv0 Moving On]], or dozens of other similar pieces without losing it.
* The scene in the Season 6 premiere when, in the FlashSideways, [[spoiler:most of the Losties are shown to be going off back to their normal lives, with their lives significantly improved by the negation of the Island. The most notable case of this is Hurley saying he is "the luckiest man alive" rather than "cursed". Locke talks to Boone about having gone on walkabout, leaving the implication his legs were never injured... until the final shot of the episode [[InSpiteOfANail shows two attendants helping him into his wheelchair]].]]
%%* "If it helps, [[spoiler: Ben]], I forgive you." "It does help, more than I can say."
* John Locke's entire story is just one big tearjerker. Abandoned by his parents, raised in a string of lousy homes, bullied in school and constantly uncertain of his place in the world. Every time something good happens to him, it is taken away in the cruelest manner possible. Life never stops relenting from piling on the misery and yet he sticks around desperately clinging to the belief that he is destined for something greater, only to end up becoming a pawn for two more powerful people. It would be almost unbearable except for the finale which says that Locke really was special and finally allows him to be happy.
* Claire's terror at giving birth is more than just fear of, well, giving birth alone on an island.
--> '''Claire:''' "It's not gonna want me. It knows I didn't want it, that I was going to give it away - babies know that stuff!"
