History TearJerker / AdventureTime

** Instead of "The Island Song" playing in the credits, we get a brand new song to close out the series, entitled "Waving to You"; as you can see from the title and the bittersweet and melancholy tone of the song it's almost as if Finn, Jake and the rest of the gang (as well as the entire show) is waving goodbye to us. an absolutely beautiful and nostalgic way to wrap up the show that saved Cartoon Network from its DorkAge and kicked off a brand new era of animation as a whole.

--->'''Jake:''' What's the status?
--->'''Finn:''' Bad news, man... I... I got dumped...

-->'''Simon:''' Hello. My name is Simon Petrikov. I'm recording this tape so that people will know my story. I was studying to be an antiquarian of ancient artifacts. Now, I've never believed in the supernatural stuff myself; just had a fascination with superstitions. But everything changed when I came into contact with this item. After purchasing this crown from an old dock worker in Northern Scandinavia, I brought it home and excitedly showed my fiance, Betty, and jokingly put it on my head just for a laugh or something. And that's when it started... the visions. I fought with them; shouted at them until I realized it wasn't real! It was the crown! I quickly took it off, and saw my fiancee in front of me, looking at me with such contempt! What had I said? What had I done when I wore this crown? All I know is, I never saw Betty again. Since then, I now see the visions always, whether or not I wear the crown. They tell me the secrets... the secrets of the ice and snow... that the power of the crown will save me with its frost. I don't yet know what this means. As you can see, my skin is beginning to turn blue. My body temperature has been lowering at a supernatural rate, to what is now about 30 degrees Celsius. I don't know when it will end. I'm really scared. I know my mind is changing... but I'm already too far gone to know what to do. I want people to know that... if I do things... if I do things that hurt anyone, please, please forgive me! Just... watch over me until I can find my way out of this labyrinth in my brain and regain my sanity! And then maybe Betty, my princess... maybe you will love me again... please love me again, Betty!

* Finn and Jake's treatment of Bubblegum in "Burning Low" [[HarsherInHindsight was rather horrible and sad in hindsight]]. Neither Finn nor Jake care for what she has to say when she originally goes to them to inform them about why Finn should stop dating Flame Princess - Finn runs off to see the girl in question and Jake falls asleep. Jake then goes on to (not illogically) misinterpret PB's actions as jealousy, and informs Finn of his ideas as if they are fact, which causes Finn to shout at PB when she discusses responsibility and sacrifice to comfort him thinking that he understood. Jake later also shouts at Peebles and throws a box of pancake mix at her. All this is going on while PB knows very well that the world is at risk. The episode ends with no apologies, and Finn giving PB the "cold shoulder" while Jake jokingly accuses her of further jealousy after the nerve-wrecking experience they had just gone through.

-->'''Finn:''' BUBBLEGUM... I CAN'T ''DO'' THIS ANYMORE!\\

-->'''Princess Bubblegum:''' Oh Lady, I should’ve never put you in danger! I saw on the heart monitor. ''I didn’t know''.

--->'''Finn''': ''[[PleaseWakeUp Don't worry Jake,]] [[SanitySlippage I'll share the secrets of the ice and snow with thee...]]''

--->'''Marcy''': I love you, Simon.\\

-->'''Marceline''': But you're gonna act weird again!\\

-->'''Air''': [[DoesThisRemindYouOfAnything I've been trapped in that bubble for so long, I've forgotten who I am!]] But now, I'm ''finally home!''

-->'''Betty:''' Simon... don't leave me like this...

--> '''Flame Princess:''' You're cold PB, and it’s not because you're a scientist or leader, it's because ''you are a bad person''. Something inside you is messed up girl, and whatever it is... '''sigh''', whatever.
--> '''Princess Bubblegum:''' Alright, keep one last fire giant. I'm not a bad person... I want you to see that.

--> '''Martin''': Finn... I'll be back for you.

--> '''Betty''': When I look at you... I just see what my life used to be like through a fun house mirror!! ''([[LaughingMad laughs brokenly]] and sheds a SingleTear)'' It's driving me ''mad''!

*** The worst part of it? When BMO shows up, alive but with a cracked faceplate, Jake keeps berating himself because, from his point of view, he just let Finn die, the threehouse being crushed into oblivione and BMO being hurt. BMO's reaction? He hugs the now smaller Jake singing him ''Time Adventure'' as a final lullaby to let him sleep one last time before the possible end.
--> '''BMO''': Let me be the papa...

--> '''Finn''': I always figured I'd go out saving somebody...
--> '''Simon:''' Hey, nobody gets to choose how it happens. The only important thing is that we're here together.

--> '''Ice King:''' [[http://chuck-charles.tumblr.com/post/59332968769/reminder-that-in-the-adventure-time-comics-finn You're just as real as I--]] ''([[LiterallyShatteredLives Fake!Betty shatters into a million pieces]])'' [[TheLostLenore --as I remember.]]

** The discoveries of Marceline's past that include living in a destroyed world, she and her dad scavenging for food, and a BastardBoyfriend to add to that!. Then there's the various villains being nastier than in the previous Seasons, excluding the Lich obviously, like the brutal Fight King that made friends and [[HoYay lovers]] kill each other, Ash the asshole and possessive boyfriend, the Lubglubs that could have also eaten a load of people, Me-Mow the tiny assassin, the fruit witches and the giant shadow beast that possibly killed Joshua, Fire King and his sociopathic daughter, and finally Stag, the freak deer who imprisoned the candy people for an extended period! It's probably on its way to get [[DarkerAndEdgier darker]], until [[EarnYourHappyEnding the]] [[BittersweetEnding finale]].

[[caption-width-right:350:[[TheWoobie Poor Simon...]]]]

* "You Made Me!". Lemongrab appears to be suicidal. [[DrivenToSuicide He opens a window and tries to either jump out or smash his own head with it]], upset that his castle has no citizens. "I AM THE EARL OF NOTHING!" Of ''course'' it's [[{{Narm}} narmy]] because of his screaming and that he survives the fall and immediately opts to start running around tearing his clothes off instead, but he's obviously EXTREMELY unhappy- enough to actually end his own existence in his despair.

*** Normal Man is horrified upon seeing Betty/GOLB. His actions have cost the life of ''another'' person he cared about, and AllForNothing.

*** Happy birthday, Stormo...

* ''Ice King''. As the series progresses, we learn more and more snippets of his backstory. And man was his life sad. Turns out he's not the evil, princess stealing, cold hearted king that we all thought he was.

-->'''Princess Bubblegum:''' Oh Lady, I should’ve never put you in danger! I saw on the heart monitor.''I didn’t know''.

[[WesternAnimation/AdventureTime What time is it?]] [[TearJerker It's sad-]] [[IncrediblyLamePun venture time...]]

[[WesternAnimation/AdventureTime What time is it?]] [[TearJerker It's sad-venture time...]]

* YMMV, but Cute King's sadness over being an IneffectualSympatheticVillain.

** From the same episode, Princess Bubblegum killed a cute little jellyfish just so she could make a sandwich. Poor little thing... *sniffle!*

** YMMV, but Starchy saying, "In your ''dreams'', you ''freak''!" to Lemongrab. [[KickThemWhileTheyAreDown Just the fact that he called him a freak]] when it's clear that the poor son of a bitch is mentally unstable and terribly unhappy. It's a YMMV example, because a year ago, [[JerkassHasAPoint Lemongrab imprisoned Starchy for no reason, so he has the right to be pissed off at the yellow idiot]].

** The entire ending of this episode, the last two minutes, is one of the happiest tear jerkers in Adventure Time's history, and one of the biggest examples of ''positive'' MoodWhiplash. Princess Bubblegum introduces Lemongrab to Lemongrab 2 (a clone of himself.) They meet each other, stare at each other awkwardly for a little bit, poke each other... then they both [[WhenSheSmiles burst into the happiest grins]] and [[HeadbuttOfLove nuzzle their foreheads together]]. Lemongrab 2 cheerfully suggests that Lemongrab pardon the prisoners, and Lemongrab agrees, sounding just as happy. The episode ends with Princess Bubblegum bidding a happy good-bye to both of the Lemongrabs, who are grinning from ear-to-ear and hoping that their "Mother Princess" will stop by and visit again. Excuse me, I have something in my eye...

*** Even worse is the reactions that Marceline has while singing the song. Besides just crying, she seems shocked as well. It could just be her finding a note Simon left explaining himself, or Marceline (like I did in a moment of FridgeLogic) realizes that besides keeping himself alive, Simon wore the crown and went insane to protect her for as long as physically (and mentally) possible.

** I noticed during Ice King's "Oh Bubblegum" song that Marcy's face shows a hint of joy and amusement. Maybe it reminds her of some goofy games she played with Simon when she was younger. Or maybe it was Simon who sparked her interest in music. Maybe she had hoped it would cause him to remember... From there, however, when Ice King starts singing about Bubblegum, her face becomes angry. There is a possibility that she, as a child, had an innocent crush on Simon. It's like in Film/TheProfessional : Marcy never knew the love of a good father, her father being an obsessive demon business man. Simon, on the other hand, did his best to take care of her. She probably feels a hint of jealousy at the mention of Bubblegum.
*** Then again, she could just be jealous of the attention.

** YMMV, but there's a scene at the beginning where Finn and Jake are mobbed by starving Lemon Children, who are trying to eat them. Jake forms his hand into the shape of a large piece of cake, and says, "Hey weirdos! Get the birthday cake!" while waving his arm towards the wall. The Lemon Children run after where they think Jake "threw" the cake. It's pretty damn sick because A) the Lemon Children are very young, B) they are starving, and C) they, ironically, had recently celebrated their birthdays. The fact that this scene was meant to be funny makes it all the more jarring.

* What about what happened to Xergiok at the end of "The Great Bird Man"? Don't tell me I was the only one who felt bad for him!
** This was a pretty heavy episode. From the suicidal mermaids at the beginning, to Xergiok slapping his best friend (a bird,) to the poor, sad look on the bird's face as he leaves, to Xergiok attempting suicide. This episode should come with a [[ContentWarnings trigger warning]], for having more references to suicide than any other.
** The poor, sad look on the bird's face.

** And at the end of Betty, Betty is seen at the end, watching the Ice King imprisoning Muscle Princess. Even though he survived, he no longer remembers her anymore. And with this context, the episode is arguably sadder than Holly Jolly Secrets, because now we know it's possible there's no way for Simon to be with his princess anymore. [[WesternAnimation/PhineasAndFerb I'm not crying, I'm sweating through my eyes!]]

* "The Nemesis". My Grod, the AdultFear in this episode, it really all culminates in universe to just this one single word. "Yes..?"

** Due to Finn killing the [[SoulJar Grass Demon]], Fern slowly begins to disintegrate (in a similar fashion to a certain [Film/AvengersInfinityWar other sad ending] until he dies shortly after Betty-GOLB leaves, finally at peace with himself. His last request is that Finn and Jake plant his remains at the now ruined treehouse.

'''Moment Subpages are Administrivia/SpoilersOff. Administrivia/YouHaveBeenWarned.'''

* A lot of it in the rather dark episode "Morituri Te Salutamus". Gladiator ghosts were forced to fight in an arena [[spoiler:and either killed or were killed by their closest friends, which is why they kept screaming for forgiveness. Though this does make their liberation at the end of the episode all the more SugarWiki/{{heartwarming|Moments}}.]]

** The look on Marceline's face when [[spoiler:Finn shows her his memory of her lost memory of her breaking up with [[{{Jerkass}} Ash]]]] is just heartbreaking. Even more so because Marceline has ''never'' had such a look before and is normally far more upbeat.

--> '''Ice King:''' [[http://chuck-charles.tumblr.com/post/59332968769/reminder-that-in-the-adventure-time-comics-finn You're just as real as I--]] ''([[spoiler:[[LiterallyShatteredLives Fake!Betty shatters into a million pieces]]]])'' [[TheLostLenore --as I remember.]]

** Oh my goodness, [[AbusiveParents Jiggler's mom nearly almost KILLING him.]] (Subverted in that this was due to a sense of unfamiliarity, since the mom did not recognize the Jiggler's juices.) And Finn's outraged response indicates the guy's got some issues about being abandoned by his parents and getting taken in by Jake's mom and dad.

** The discoveries of Marceline's past that include living in a destroyed world, she and her dad scavenging for food, and a BastardBoyfriend to add to that!. Then there's the various villains being nastier than in the previous Seasons, excluding the Lich obviously, like the brutal Fight King that made friends and [[HoYay lovers]] kill each other, Ash the asshole and possessive boyfriend, the Lubglubs that could have also eaten a load of people, Me-Mow the tiny assassin, the fruit witches and the giant shadow beast that possibly killed Joshua, Fire King and his sociopathic daughter, and finally Stag, the freak deer who imprisoned the candy people for an extended period! It's probably on it's way to get [[DarkerAndEdgier darker]], until [[EarnYourHappyEnding the]] [[BittersweetEnding finale]].

* Lumpy Space Princess's {{Heroic BSOD}} after finally realising that nobody is the person they used to be is fairly distressing in it's own right. Everyone in the land of Ooo has basically become either a sad, lazy, angry or sweet shadow of their former selves except for LSP and three others, [[ClassicalAntiHero and she bemoans her ineptitude and inability to save anyone all on her own]] when even Finn falls to the influence of the elements. Of course the fact that her immunity is the key to saving Ooo is what ultimately makes her heroic action at the end of Elements so SugarWiki/{{heartwarming|Moments}}.

** Instead of "The Island Song" playing in the credits, we get a brand new song to close out the series, entitled "Waving to You"; as you can see from the title and the bittersweet and melancholy tone of the song it's almost as if Finn, Jake and the rest of the gang (as well as the entire show) is waving goodbye to us. an absolutely beautiful and nostalgic way to wrap up the show that saved Cartoon Network from it's DorkAge and kicked off a brand new era of animation as a whole.

** Oh my goodness, [[AbusiveParents Jiggler's mom nearly almost KILLING him.]] (Subverted in that this was due to a sense of unfamiliarity, since the mom did not recognize the Jiggler's juices.)
-->'''Finn:''' [[ParentalAbandonment Moms are supposed to love babies!]] [[TheWoobie They're supposed to]] ''[[TheWoobie love]]'' [[TheWoobie babies!]]

[[quoteright:304:https://static.tvtropes.org/pmwiki/pub/images/Simon_Petrikov_738.jpg]]

** It was the Mushroom War that created [[spoiler:the Lich and reintroduced magic]] with the use of some scary bombs. The Land of Ooo looks bright and cheerful but it is a total crap sack death world hidden underneath.

-->'''N.E.P.T.R.:''' Shall we capture princesses now, Papi?"\\

* An early scene of "Crystals Have Power", in which we see that Finn is still upset after [[spoiler:Tree Trunks exploded in her self-titled episode.]] At least it was comforting to see [[spoiler:that she's still alive, just mad with power as queen of the crystal people.]]

** Really, imagine how [[spoiler:terrible]] Finn felt going back home after this episode.

-->'''Finn:''' [[ParentalAbandonment "Moms are supposed to love babies!]] [[TheWoobie They're supposed to]] ''[[TheWoobie love]]'' [[TheWoobie babies!"]]

* The ending of "Susan Strong", where Finn [[spoiler:has reason to believe Susan is an actual human.]] "Susan.... [[ArmorPiercingQuestion what are]] ''[[ArmorPiercingQuestion you?]]''" She just runs off into the night.

* The title card for [[http://adventuretime.wikia.com/wiki/File:Titlecard_S2E25_mortalrecoil.jpg Mortal Recoil]]. Even if [[spoiler:Princess Bubblegum ''isn't'' KilledOffForReal]]. Finn's expression might not say much, but the way he's holding the like-like sweater ...

** The snail is frowning & waving as if [[spoiler:saying goodbye to PB]].

* In the episode "Mystery Train", when Finn thought that [[spoiler:Jake was killed by the conductor.]] It was too close to the end of the episode for comfort, and just the look on Finn's face when it first happens... he even ''sounds'' heartbroken. Then before going after the conductor in his unstoppable rage, he ever so gently places [[spoiler:Jake's skeleton]] on the ground. Finn's whole reaction is sad.
-->'''Finn:''' (''trembling, in a small voice while looking despairingly at [[spoiler:Jake's skeleton]]'') [[spoiler:J-J-Jake?]] (''carefully picks it up and hugs it'') [[BigNo NOOOO!]]

** It doesn't help that [[spoiler:Ice King used to be a young human that was cursed and is trying to find his way out of his mind.]]

* In "The Limit", Jake nearly dies. Jake says that Finn should wish for the Ancient Psychic Tandem War Elephant anyway, because that's what they wanted... that's what ''Finn'' wanted. What an unselfish guy. [[spoiler: It also turns out to be a genius move on his part since the Elephant itself also gets a wish, which is to revive Jake.]]

** Worse, according to word of god [[spoiler:they weren't just best friends. They were lovers. More specifically, ''male'' lovers.]]
* In "Memory of a Memory", we see Marceline as a cute sweet little girl, after ''the friggin apocalypse''. We see her try to fix her broken down teddy bear with her very last piece of string, and says "I'm hurting you because I love you!". What could possibly top that? [[spoiler: Her boyfriend sold the teddy bear to a witch, because it was her most valuable possession]], and [[ContinuityNod we see her dad eating her fries, which makes her cry.]]

** [[spoiler: The loss of her teddy bear]] is [[HarsherInHindsight even sadder]] after "I Remember You" [[spoiler: revealed that Simon Petrikov, (A.K.A. Ice King), was the one who gave her this teddy bear, to make her stop crying when she found herself nearly alone and helpless in the midst of the Great Mushroom War. Now that Simon has completely lost his mind and identity, the teddy bear was her last souvenir from the days when her dear friend and father figure was still himself. And that is why she loved it.]]
** [[spoiler: While Marceline's father was eating her fries, there's some money on the counter. Money that looks relatively unspoiled. The little girl was probably starving, but she apparently felt uncomfortable just taking the fries and actually paid for them, with money no one was alive to use.]]
* Finn's sadness at the end of "Too Young". If only Lemongrab never showed up, then maybe [[spoiler: Princess Bubblegum could have stayed 13 instead of having to revert back to her 18 year old self]]...
** The part where [[spoiler:she turned 18 again and told Finn to move on was made worse considering how much love she displayed for Finn before.]] Finn's dejected look after this happens, especially after Jake calls, was utterly heartwrenching.

--->'''Finn:''' [[spoiler:Bad news, man... I... I got dumped...]]

* "What Was Missing" had a few, but the ending where Bubblegum reveals that [[spoiler:what she lost was an old shirt Marceline once gave her]] was probably the biggest.

* Around the end of "Apple Thief", [[spoiler: Tree Trunks calls for the Banana Guards to come over and arrest her because she thinks she stole her own apples. Not only does she sound so distressed with a depressing look on her face, but imagine if you were one of the banana guards. How would you react if you heard an old lady over the phone tearfully explain how she did something she thought was a bad crime?]]
* In "The Creeps", everyone is seemingly killed one by one. So what's the sad part? Finn's reaction [[spoiler: when he sees PB melt. It reveals he just meant on playing a little prank on Jake after what happened in "Mystery Train", but things went horribly wrong and he feels sadly responsible for their deaths. His voice just says it all.]]

* In "Jake vs. Me-Mow", in an attempt to lull Me-Mow to sleep (though he is also fully knowledgeable of the fact that [[spoiler:he may die]]), Jake requests that Finn sings the song their mother's lullaby using her music box. Finn accepts and the result is [[MagicMusic everyone who hears the song falls asleep]]. For the fans, it means there's not a dry eye in the house.

** Finn breaking down and tearfully hugging a [[spoiler: dying Jake after the antidote breaks.]] It takes them about five seconds to realize the solution to their problem [[spoiler: which is to increase his liver to 51 times its size so that the injected poison is essentially a droplet in comparison]], but it's still a sad moment.

'''Finn:''' *holding onto Jake's leg* NO!\\

'''Finn:''' [[BreakTheCutie *crying*]] [[HeroicBSOD Please... Please...]]\\

* In the Christmas special, we finally learn [[spoiler: the Ice King's]] origins. [[spoiler: [[FromNobodyToNightmare He was just an antique dealer]] before the Great Mushroom War, until he bought a [[EvilMask crown]] off a Scandinavian merchant. He was with his fiancee when he put it on. He completely lost control, [[OutOfCharacterAlert started spewing nonsense and phrases]], but he had no recollection of it. Whatever he said or did was horrible enough to [[PleaseDontLeaveMe make her leave him]]. [[CollateralAngst He never saw his fiancee after that]]. He chronicled his transformations from the crown through the [[CaptainsLog video]], growing more and more like the Ice King each entry. We finally find out why he tries to capture princesses: he's trying to find his old fiancee, whom he never saw after he put on the crown. Arguably the worst part? He [[AndIMustScream remains perfectly aware of his transformations, never becoming completely controlled by the ice crown.]]]] [[AlasPoorVillain Holy]] ''[[PrecisionFStrike shit.]]''

-->'''[[spoiler:Simon]]:'''"Hello. My name is [[spoiler: Simon Petrikov. I'm recording this tape so that people will know my story. I was studying to be an antiquarian of ancient artifacts.

And then maybe Betty, my princess... maybe you will love me again... please love me again, Betty!]]!"
** [[spoiler: Both Tearjerker and Heartwarming when you realize after "Betty" that she never stopped loving him. She vanished from his past life because she had gone through a portal 1,000 years into the future that the Ice King (in temporary Simon form) had originally created to apologize to her, to try and save him.]]
** [[spoiler:Simon Petrikov calling his fiancee his "princess", eventually breaking down into tears, begging Betty to "please, love [him] again".]]
** [[spoiler:Simon begging the viewer to forgive him for whatever he does while he is insane, until he can manage to find his way back from the depths of madness.]]
** [[spoiler:Simon slowly losing his sanity, forgetting his past as a human, his own name, and his fiancee, soon declaring himself "too far gone" to be free of the crown's effects on him.]]
*** [[spoiler:Probably the worst part comes when you realize the Ice King is so far gone that the secret he was trying to keep was that he used to wear glasses. He just heard ''every last word'' of his story ''from his own mouth'', and he '''still''' can't seem to fully grasp the true scope of what's happened to him anymore.]]
*** [[spoiler:Even worse is that he doesn't realize the tapes belong to him when Finn gives them back. He thinks it's a nice gift, commenting how he used to have tapes like that.]]
** [[spoiler:You will never be able to laugh at the Ice King's antics ever again the same way again.]]
** [[spoiler:Pretty much anyone's first impulse after this episode is to try and give him a hug.]]
** [[spoiler:This also makes the "I'm still not happy" at the end of "The Eyes" extra tragic- at some level, he must remember what he's lost, just enough to still be unhappy even with friends at his side for a brief moment. He knows somehow that, as comforting as sleeping with friends in his arms is, something very important is still missing.]]
** [[spoiler:Suddenly, all of his powers coming from his crown (a nod to the original short) makes perfect sense.]]
** [[spoiler:As he goes mad, you can see the snow accumulating outside the window until what was once a regular city turns into the Ice Kingdom, presumably ''killing everyone there.'']]
*** The actual reason for that climate change? [[spoiler: ''It's a nuclear winter''. The knowledge of what's going on in those final tapes makes them even more bleak: this man has witnessed unimaginable horrors, dealt with everything life could throw at a person, ''survived a nuclear war'', and successfully fought to keep his sanity through it all. Now he's lost the battle, and the only thing he can do about it is plead to whoever finds his tapes for forgiveness.]]
** Immediately after the video plays, Finn gives him the tapes and he [[spoiler:doesn't remember what was on them. It's funny at first, but then it hits you that it's revealing that every wacky, goofy thing he's done on the show was really the product of his insanity and mental illness, and Finn and Jake just didn't pay close enough attention.]]

** If you pay attention to the background at the end of the episode, you'll see that Marceline isn't in the room watching videos with everybody else, instead she's floating outside, frowning. [[spoiler: After seeing ''I Remember You'', you'll realize that this is likely because at that point in time Marceline still couldn't bring herself to even be in the same room as her former father figure.]]
** Simon's despair in the final few tapes becomes even more heartbreaking when you consider that, sometime shortly before that, [[spoiler: he'd had to abandon his adoptive daughter for fear that he'd become a danger to her.]]
** [[spoiler:Compare how the Ice King acts a thousand years later, to how Farmworld Finn acts only two after two years (assuming time passed in Farmworld the same as in Ooo). The crown is driving Farmworld Finn to freeze the entire world - which Ice King hasn't even come close to doing after so much time. Simon Petrikov's noble soul is still in there, fighting off the worst whisperings of the Crown after all this time, which even the hero can't seem to do. And he's paying for it.]]

* In "Another Way", Finn's realizes that he [[spoiler: mortally injured three people]] in order to have his way. This realization comes with a sad song that marks the return of the auto-tune.

* In "Ghost Princess", [[spoiler:Clarence ''kills'' himself over Ghost Princess's death, which he himself caused.]]
** [[spoiler: Clarence]]'s facial expressions and the way he cries when [[spoiler: killing Warrior Princess, who would then become Ghost Princess as a result.]]
* In "Dad's Dungeon", Jake follows Joshua's advice and frequently insults Finn by calling him a baby, like Joshua does on the tapes. While it was originally meant to be good reinforcement for Finn, [[spoiler:it ends up making Finn want to kill himself from disappointment in himself.]]

* "Incendium" is pretty heartbreaking from the Flame Princess' point of view. Though Jake had good intentions going into it, he ''really'' yanks her chain hard by lying to her father, claiming that he's an envoy of ''Prince'' Finn sent to request the chance to woo her, [[spoiler:earns that right, then backpedals after hearing she's a PersonOfMassDestruction]]. Way to go, Jake.

* [[CerebusSyndrome Season three]] in regards to Finn if you think about it. He finally gets to be with his dream girl in "Too Young" when PB gets de-aged and that only lasts a short time. They kiss and she doesn't remember any of it and treats it like it was years ago. Then comes "What Was Missing" when he just wants to hang out with his friends Marceline, PB and Jake to form a band to get their stuff back but the three all just fight until he sings his sad little song. In "The Creeps" he apparently made PB a sweet sixteen b-day card and she doesn't remember. Then in "Holly Jolly Secrets" [[spoiler:Ice King turns out to be formerly human, making Finn and Susan Strong both alone and not alone at the same time]]. Then in "Dad's Dungeon" he feels like his adopted father never loved him. Add in the above quote from the same episode and it seems like he's having a hard time trusting people. Hopefully this [[LighterAndSofter lightens up]] for season 4.
** The discoveries of Marceline's past that include [[spoiler:living in a destroyed world, she and her dad scavenging for food, and a BastardBoyfriend to add to that!]]. Then there's the various villains being nastier than in the previous Seasons, excluding the Lich obviously, like the brutal Fight King that made friends and [[HoYay lovers]] kill each other, [[spoiler:Ash the asshole and possessive boyfriend]], the Lubglubs [[spoiler:that could have also eaten a load of people]], Me-Mow the tiny assassin, the fruit witches and the giant shadow beast [[spoiler:that possibly killed Joshua]], Fire King and his sociopathic daughter, and finally [[spoiler:Stag, the freak deer who imprisoned the candy people for an extended period]]! It's probably on it's way to get [[DarkerAndEdgier darker]], until [[EarnYourHappyEnding the]] [[BittersweetEnding finale]].

-->'''Finn:''' [[spoiler:She hugged me then left.]]\\

** The episode is just depressing. It presents a rather complicated morality issue: Flame Princess believes her only purpose is to burn and expand her kingdom, so she thinks she's justified in burning innocent people to death. This presents a problem to Finn and Jake, who are heroes, ''but'' they can't extinguish the flames without hurting her, which is a problem since Finn likes her. This entire issue is what makes him finally break down and cry. There are a couple of sad lines like "Why can't I just like a girl?" and out of nowhere, [[spoiler: NEPTR]] says "Even if everyone burns, you'll still have me, [[spoiler: creator]]," which is heartwarming sure, but it makes the possibility of everyone in the kingdom burning to death that much ''real''. And finally, the resolution to the episode (yes, even the '''''resolution''''' is depressing): Flame Princess thinks Finn is a [[spoiler: water elemental since she thinks he constantly cries]] (which is understandable since, coupled with "Incendium", Finn hasn't been having the best time in his life). Using this reasoning, [[spoiler: [[StarCrossedLovers she believes they can't be together.]] All of this quells Flame Princess's emotions and [[BittersweetEnding makes the fires burning the kingdom go away]]]].

** The ending with [[spoiler:PMW giving all her body parts back to the princesses]] has the Ice King saying [[spoiler:"She gave all my stuff away!"]]. While that may be [[MoodWhiplash poor]] [[DudeNotFunny taste]], it also means that Ice King [[spoiler:can't form long term relationships; once they're gone, he doesn't show a remote interest in them]], which is a both a tear jerker and a sign [[CallBack of sociopathy.]]
*** A note on the sociopathy. When was the last time we saw the Ice King play a major role in an episode? "Holly Jolly Secrets". At the beginning he seemed quite like his normal self, but once once we found out about [[spoiler: the crown and Simon Petrikov]], it looked like he was going to be a TragicVillain who would eventually become good. This episode wipes the slate clean, seeing that he did the one thing we never expected him to do and that is hurt a princess. This train of thought allows us to see the Ice King [[SanitySlippage slipping further into insanity]].

** The ending. [[spoiler:To defeat Goliad, PB has to make another clone, but this time she uses Finn's DNA to make a bird creature called Stormo. Finn sees the connection and thinks of him as a son. Unfortunately since Stormo and Golidad are psychic equals (and immortal), they'll be having a mind battle for eternity]].
*** [[spoiler:Happy birthday, Stormo...]]

* A short one in "Beyond This Earthly Realm" when the Ice King is explaining that with his "wizard eyes" he is able to see creatures of the spirit plane but he can't touch them, he goes from "Can't touch them..." to "can't KILL them..." and finish in a very dark tone "I hate them!", because seeing this creatures was the first transition to become the Ice King and at some level he knows it's probably the cause of [[spoiler: his break up with his fiancée Betty]]

* "Princess Cookie". In the episode, a cookie who is crazy holds the Candy People hostage to steal Princess Bubblegum's crown. Later in the episode, he is threatening PB because [[spoiler:as a child, PB crushed his dreams of being a princess (he's a male).]] So what does he do after Jake comforts him? [[spoiler:Commit suicide. [[TearsOfJoy And is happy about it.]] But [[BungledSuicide he fails at doing so]] [[DisneyDeath and ultimately survives]].]]
** At the hospital, [[spoiler:he is crowned Princess of the Grass Kingdom.]] SugarWiki/HeartwarmingMoments should have a page for this episode.
** What makes it extra sad is that [[spoiler: Princess Bubblegum's laugh wasn't cruel but more amused like she found his comment cute and could be a case of a bad misunderstanding]].

* Finn and Jake's treatment of Bubblegum in "Burning Low" [[HarsherInHindsight was rather horrible and sad in hindsight]]. [[spoiler:Neither Finn nor Jake care for what she has to say when she originally goes to them to inform them about why Finn should stop dating Flame Princess - Finn runs off to see the girl in question and Jake falls asleep. Jake then goes on to (not illogically) misinterpret PB's actions as jealousy, and informs Finn of his ideas as if they are fact, which causes Finn to shout at PB when she discusses responsibility and sacrifice to comfort him thinking that he understood. Jake later also shouts at Peebles and throws a box of pancake mix at her. All this is going on while PB knows very well that the world is at risk.]] The episode ends with no apologies, and Finn giving PB the "cold shoulder" while Jake jokingly accuses her of further jealousy after the nerve-wrecking experience they had just gone through.

** In the episode, PB was [[spoiler:forced to attempt to kill Finn in order to kill Flame Princess to save the Land of Ooo. She had Jake plug up the hole they were in so that Flame Princess would run out of oxygen to burn with. Just when you think the show can't get darker...]]
** [[spoiler:Finn giving his oxygen to Flame Princess, making himself pass out.]]

** It is heavily implied that Princess Bubblegum had [[spoiler:a failed romantic relationship in the past which she gave up because of her responsibilities]]. To make this worse, this is hinted at just before Finn goes ballistic and shouts at her at how she broke his heart.
--->Princess Bubblegum: Finn, sometimes you want someone and you ''(puts hand on Finn's left knee)'' want to kiss them, and be with them. But you can't, because responsibility demands sacrifice.

** We find out that [[spoiler:Flame Princess has been locked in a lamp for most of her life because she could destroy the world if she experiences romance]], and this is why she is so innocent and naive.
** Princess Bubblegum's talk to Finn get's yet another layer of depressing [[RewatchBonus in light of later episodes]], [[spoiler: as it becomes pretty apparent that Bubblegum is describing her own nasty breakup with Marceline to Finn.]]

** The Ice King, [[spoiler:minus his heart]], lying on the ground and getting stepped on by [[spoiler:Ricardio (A.K.A. his heart)]]. Poor thing! And at the end, when [[spoiler:Princess Bubblegum]] saves him by [[spoiler:giving him a heart transplant, complete with maracas.]] And his happiness.

** Lady at the end of the episode, when he was revealing that [[spoiler:she is pregnant]]. She looked like she was either scared Jake won't accept that or that something could've happened to [[spoiler: [[AdultFear the babies after all that beating she received]]]].
** Bubblegum every time Lady Rainicorn is hurt, especially towards the end. It's ''very'' clear she cares about Lady immensely and you can practically hear how much it hurts her to see her hurt. [[spoiler:Taken UpToEleven when she realizes that Lady Rainicorn was ''pregnant'' the entire time and just how much danger she was really in.]] Is it any wonder she [[spoiler:beat Ricardio to a pulp for what he did?]]

--->'''Lemongrab:''' "No! No more helping! YOU'RE the one who made me this way! How can YOU help?! You unload your punkest boys on me?! ''Try'' to change my ways? You're poison! YOU'RE POISON! YOU NEED RECONDITIONING!"

** The title card for [[http://images.wikia.com/adventuretimewithfinnandjake/images/7/75/I_remember_you_title_card.jpg "I Remember You"]] showing [[spoiler: Ice King looking at his reflection--Simon Petrikov in his third stage.]]
** [[spoiler: Marceline is absent from the title card, which is strange, considering the huge role she plays in the episode. Then you realize why: At that point, Simon had already forgotten Marceline completely.]]
** The rest of the episode was just as tear-worthy. [[spoiler: Especially how Marceline was so desperate for her only friend left from her childhood as well as her father figure to remember her. Especially after "Marceline's Closet", where she states that no one can relate to her because no one went through what she has... except apparently Simon.]] And the ending...[[spoiler: Marceline's most treasured possession, which she has been shown to care for as a child almost, and which she has broken up with a boyfriend over, was a gift from Simon.. .and it's implied that that's why it's so special to her.]]

** Made worse when you realize on some level, the Ice King does still care. Marceline even says he makes excuses to come see her [[spoiler: even if he can't remember her. Like when he pushes her off him after she tries to stop him acting crazy. He at once feels guilty about it, and sounds almost, ALMOST slightly sane as he apologizes! Considering he's a crazy sociopath who once said "oops I've got the dropsies!" when he almost killed Bubblegum. The scene comes off almost like the Ice King has a subconscious fear of physically hurting Marceline in anyway.]]
*** If one considers how reflexively he responded like that, they might think that it was something that came up (perhaps frequently) before. [[spoiler: The idea of a small child trying to get a grown man to control himself and for him to respond violently, before profusely trying to apologise and explain...]]
** The song they were singing. Not because of the lyrics, because [[spoiler: it was a note left by Simon trying to explain what was happening to him. Marceline freaking CRIED while singing it]].

*** Even worse is [[spoiler: the reactions that Marceline has while singing the song. Besides just crying, she seems shocked as well. It could just be her finding a note Simon left explaining himself, or Marceline (like I did in a moment of FridgeLogic) realizes that besides keeping himself alive, Simon wore the crown and went insane to protect her for as long as physically (and mentally) possible.]]

---->[[spoiler:''Marceline, is it just you and me in the wreckage of the world?\\

I swear, it wasn't me. It was the crown.'']]
*** The line [[spoiler:"Please forgive me for whatever I do when I don't remember you"]] is particularly heartbreaking; [[spoiler:it could be seen as Simon's way of [[ApologeticAttacker retroactively apologizing to Marceline if he hurts her when he slips into complete insanity]]]].
*** [[spoiler: You can even see Marceline closing her eyes as she sings the refrain a second time. Possibly pretending that it's Simon singing this with her and not the mad thing that's grinning like an idiot.]]
*** [[spoiler: The look on Ice King's face near the end when he's singing the note; he looks at first surprised, then depressed. He might actually be remembering who she is, at least while they're singing.]]
** This even makes a random silly plot point from [[spoiler: Marceline's debut episode]] depressing. [[spoiler: She has a lot of homes and keeps moving between them. Why? Because she usually leaves whenever Ice King finds her again. Why does she leave when that happens? Because she can't bear to see him like this.]]

** [[spoiler: Marceline almost sobbing as she yells at the Ice King to look at the note he wrote himself.]]

** The final scene of the episode is completely heart breaking when you realize [[spoiler: Simon was once a very kind person who looked after a helpless, lonely little girl as the world went to hell around them. The way he smiles as he wipes Maceline's tears away, then brings her a teddy bear to cheer her up is so sweet, the fact he's been reduced to a crazy, pathetic old man who has been suffering from his insanity for centuries makes you want to cry right along with Marceline.]]

** The Ice King's scribbled lyrics on [[spoiler: the old newspaper article documenting one of his discoveries]]. In brainstorming a love song for princesses, he almost writes that he's been working on his ''personality''. He ended up changing it to "working on [his] pecs". Either he gave up hope that he could change his personality for the better, or he doesn't understand that he really needs to. Tragic either way.

** As if these weren't bad enough, the original title of the episode was supposed to be, simply, [[spoiler: "Help."]]
** [[spoiler: One of the worst aspects of this episode in hindsight is the beginning, when Marceline sees the Ice King heading towards her home, all she says is a quiet and almost desperate "no" upon realizing that he's found her once again, and again she has to confront the fact that someone she cares about has been driven almost completely insane.]]
*** The Ice King trying to kiss Marceline after she says she cares about him. Wrong at first on so many levels, but the more you think about it the worse it becomes. [[spoiler: It means that the Ice King at this point doesn't recognize Marceline as different in any way to all the princesses he always tries to steal. Oh and just try and imagine the absolute {{Squick}} that must have been for Marceline to have a man she considered a father figure try to kiss her, with the added bonus that it spells out that the Ice King remembers ''nothing'' about their bond.]]
*** Alternatively, it could suggest that [[spoiler: some part of Simon still exists inside the Ice King.]] During their hug, something deep within the Ice King may have awoken, [[spoiler: reigniting the bond he once shared with Marceline. In this fleeting moment of parental affection, maybe Simon just wanted to give Marceline a kiss on the cheek or forehead as a parent would to comfort a child and reassure her that he still exists somewhere deep inside his own psyche. However, since the Ice King is completely crazy, his mind can't differentiate between parental affection and intimacy, and all he could register out of it was 'Kiss Marceline'. It's even sadder when you realize that this goes to show how any of Simon's attempts to come through will always be foiled by his own madness.]]

** Hindsight tearjerker from Holly Jolly Secrets, [[spoiler: Marceline didn't enter Finn's house, this seemed strange and now we know why. She can't bear to seeing Simon again.]]
** Ice king tends to go after younger women. Much younger women. Maybe he's not looking for a wife. [[spoiler: Maybe he wants to reclaim the happiness he had with Marcy, but, due to his insanity, cannot separate love for a wife from love for a daughter.]]
*** This makes more sense when one looks back at his interactions with most princesses: overprotective, tactful, essentially treating them like a child. Up until now, it was an example of classic chauvinism, degrading women by treating them as though they were incompetent. But after this episode...Maybe he just wants the [[spoiler: little princess Marcy]] back.
** I noticed during Ice King's "Oh Bubblegum" song that Marcy's face shows a hint of joy and amusement. [[spoiler: Maybe it reminds her of some goofy games she played with Simon when she was younger. Or maybe it was Simon who sparked her interest in music. Maybe she had hoped it would cause him to remember...]] From there, however, when Ice King starts singing about Bubblegum, her face becomes angry. [[spoiler: there is a possibility that she, as a child, had an innocent crush on Simon. It's like in Film/TheProfessional : Marcy never knew the love of a good father, her father being an obsessive demon business man. Simon, on the other hand, did his best to take care of her. She probably feels a hint of jealousy at the mention of Bubblegum.]]

* [[spoiler:Finn fighting with Princess Bubblegum for her crown during "The Lich". She accidentally cuts his face with the scissors towards the end of it, and there's this look that Finn shoots her, one of complete and utter betrayal, that's just heartbreaking.]]

** It was a frightening shock for Princess Bubblegum too: [[spoiler:She's just having a normal night of science, when out of nowhere, Finn, her trusted friend/champion, crashes through the ceiling and demands her crown's gem. When she protests, he instead goes for it like a maniac, and in trying to fight him off she accidentally slices him across his face.]] Only once she catches up to Finn does she learn the reason for his actions.
** Which leads to the real TearJerker moment for Finn, [[spoiler:all this time he was helping the Lich. And then when he tries to fix the problem by destroying the Enchiridion, [[NiceJobBreakingItHero he ends up creating the portal instead]].]]
** In the scene where Princess Bubblegum [[spoiler:tells Finn that Billy is actually the Lich]]. It isn't that sad, until one of the Gumball Guardians [[spoiler:attacks Billy aka The Lich, and Finn has this panicked look on his face while screaming his name]]. The moment was made all the more heartbreaking once [[spoiler:Finn finally realized he was being used]].
* [[spoiler: The very thought that The Lich murdered Billy and possibly the Old Lady! [[NiceJobBreakingItHero And it was all thanks to Finn giving that bear the Enchiridion]]!]]
** [[spoiler: From the same episode, a [[http://tylerkungpao.tumblr.com/post/35365952684 deleted storyboard]] ('deleted' meaning it was very likely supposed to be canon) shows that Finn's birth-father was wrongfully cast into another dimension of the Multiverse, and is fighting for his life to this day. On top of this, Finn has ''just'' figured out he's adopted, and the look on his face as the gears turn in his head...]]

* [[http://images1.wikia.nocookie.net/__cb20121109234454/adventuretimewithfinnandjake/images/thumb/3/3a/Ice_King_is_Dead.png/640px-Ice_King_is_Dead.png Here we see]] [[spoiler: that in the alternate universe Finn wished up, where the Lich never came to be, Simon died horribly, trapped under a nuke he froze mid-flight. We also see this alternate universe's Marceline, who didn't turn into a vampire and instead became [[AgeWithoutYouth a very elderly]] (and somewhat senile) woman who has spent her life guarding the crown.]]
** Even worse [[spoiler:he [[HeroicSacrifice sacrificed himself to stop the Great Mushroom War]] but nobody would even know of his sacrifice, with people believing that magic never existed.]]
** Also, [[spoiler:AU!Finn putting on the [[ArtifactOfDoom Ice Crown]] to save his family and sending them away after it drives him insane.]]
*** [[spoiler: The cries of his infant sibling snaps AU-Finn out of his insanity, permitting him time to apologize and send them away.]]
*** Even worse when you consider that due to the radiation from the bomb, they probably wouldn't have survived anyway. Thankfully, [[spoiler:Jake put a stop to that universe.]]
*** It's all made worse [[SugarWiki/HeReallyCanAct by Jeremy Shada's]] ''[[SugarWiki/HeReallyCanAct awesome]]'' [[SugarWiki/HeReallyCanAct performance.]] ''Especially'' when [[spoiler:he finds Jake in the pool of radiation.]]
--->'''Finn''': ''[[spoiler:[[PleaseWakeUp Don't worry Jake,]] [[SanitySlippage I'll share the secrets of the ice and snow with thee...]]]]''
** [[spoiler: Barnverse!Finn pulling his Jake out of the Lich's pool... only to find that his old friend is now a new Lich and, thanks to the crown, Finn is more than willing to kill him. Jake's, the one from the main timeline, reaction as he watched helplessly from Prismo's time room only makes things worse.]]
--->'''Jake''': [[spoiler: Finn wait that's not me! I'm here Finn, I'm here.]]
** In the multiverse, many different possibilities, outcomes, and differences exist. In other words, it's actually possible that [[spoiler: the universe that Finn just created is still out there. And everything probably just kept getting messed up and horrible. Plus, remember. Finn JUST put on the Ice King's crown. Which means, he may come back to himself and realized what he's done or doing. If he wins against Jake, he would've killed one of his best friends (similar to what happened to Simon with Betty in a way).]] That's straight up depressing.
** According to what Prismo said, [[spoiler:the Finn we know may not even be the Finn we've been watching all throughout these years. That Finn could probably be still stuck in the Farmworld, going crazy from the crown's influence.]]

** Even before [[spoiler:the apocalypse being started by Finn]] is that things were still sad, but still had a bit of a cheery feel to it. Alternate Finn had to [[spoiler: sell a mule named Bartram (or Barbar) he loved to help his family, but tries to avert that from happening the best he can.]] Then he encounters [[spoiler: Alternate Marceline who already had been through a lot and steals the crown from her in an attempt to sell it instead of Barbar. Then the Destiny Gang burn his hometown and steal the very mule he was trying to save. He then tries to save everyone after facing them by putting the crown on. [[NiceJobBreakingItHero It doesn't end well obviously.]] He by accident sets off the very bomb Simon stopped, making Simon's death all for nothing in the end. Then Finn kinda tries to save everyone with his ice powers only to be called insane, despite that he technically is. Then he has to watch his own loyal pet dog crawl towards him disturbingly and almost zombie-like as Jake turns on him. Then he has to fight him. And all of this from him just wanting to find another way instead of selling Barbar. Instead, all involved have SOMETHING bad happen to them. DoesThisRemindYouOfAnything From a [[CallBack previous]] episode?]] It's really depressing in hindsight since Finn didn't want this and all he wanted to do was help. Instead, [[spoiler: all hell breaks loose on what was a pretty normal day for him.]]

* Major Fridge TearJerker on someone you ''never'' thought would evoke sympathy of any kind: [[spoiler:after what happened to Farmworld Jake, we know that the Lich isn't the cause of the Mushroom War-[[FromNobodyToNightmare he's someone who just happened to be in the wrong place at the wrong time, and got turned into a living weapon.]] The guy would've had nothing to do with the Mushroom War conflict, yet he gets [[FaceMonsterTurn unwittingly warped]] into an undying, UltimateEvil OmnicidalManiac [[LossOfIdentity with nothing left of him but his mutated body.]] The Lich may be terrifying, but [[AlasPoorVillain to see why...]]]]

** The ending. [[spoiler:Ice King reveals he brought Lemongrab, NEPTR, Shelby and Tree Trunks down to the dungeon to get the magi-flame, a flame that can bring inanimate things to life which he intends to use on his omnibus collection of [[CallBack Fionna and Cake fanfiction and bring Fionna, Cake and Marshal Lee to life.]] Unfortunately the flame only brings the ''book'' to life and not anything else. [[SugarWiki/HeartwarmingMoments NEPTR then comforts his papi by telling him his characters all exist in his dreams and imagination.]]]]

* In "Simon and Marcy," there's the part when [[spoiler:Simon has no choice but to break his promise to Marceline and wear the crown that they both know is turning him into the Ice King.]]
** Specifically, [[spoiler:Marceline begging Simon not to wear the crown, because it makes him "act weird". Sure enough, when he puts it on it's like someone flips a switch and the Ice King takes over. And Marcy can't get through to him. Even after she knocks the crown off, Simon's ''still'' in Ice King mode, and doesn't snap out of it until Marcy says he's scaring her.]] For the record, Marceline is ''seven'' when these events take place.
** We find out "Gunter" is a name applied by the Ice King persona to the people he cares for. [[spoiler:Specifically, it applied to Little Marcy - but in the same vein of Ice King forgetting "Princess" applied to Betty, "Gunter" now applies to his penguins.]]

'''Simon''': I love you too... [[spoiler:Gunter.]]
*** Unless the viewers want to depress themselves further, and assume [[spoiler:he gets the name wrong because for all his good intentions, Simon's actions just fractured his mind a little more. The first time he calls her Gunter is when he's consumed by the Ice King persona, after all.]]
*** It's probably ''is'' that, because [[spoiler: when he called her "Gunter" the second time, he still had longer hair and bluer skin, instead of reverting back to how he looked for most of the episode.]]

*** This brings up the possibility that the penguins he's named Gunter are, in fact, [[spoiler:his attempts at replacing Marceline. Think about it- they're about the same size, they have the same color scheme, he treats them like they're his children...]]
*** Or that he thinks the penguins are in fact Gunter,[[spoiler: aka young Marceline. This would also explain why he remembers Marceline, but can't seem to remember who she is: he thinks Marcy aka Gunter still lives with him at his castle.]] This becomes particularly likely when you consider how the madness induced by the crown is similar to actual dementia: it isn't at all uncommon for sufferers to think their kids are still young, even if they are talking to their fully grown children. In fact, Gunter being young Marcy's nickname would also explain why her journal has "Gunter" written on it in "Marceline's closet".

** Whenever Simon [[spoiler:wears the crown, his appearance shifts closer to the Ice King (colder blue skin, longer nose, beard and hair, etc.). The first time, the changes reverse shortly after Marceline knocks the crown off. The second time, after Simon fights off the monsters, they... don't. This time, most of the physical changes seem permanent. Also, his outfit changed colors to blue, and he lost his glasses.]]

** On a more Meta level; one of the episode's writers, Cole Sanchez, revealed in a [[http://4ms.me/13wJPPn Formspring post]] that originally, [[spoiler: little Marcy was so sick that Simon legitimately believed she would '''''die''''' if he didn't get her medicine,]] but Creator/CartoonNetwork thought that would traumatize children, so it was changed to [[spoiler: her illness being less severe and the two looking for chicken soup.]] Sure, we know that either way, she would have turned out all right in the end, but the mere thought of that would make anyone's heart sink.

** Another sad thing about [[spoiler: Finn's death]] is when Bonnie, [[spoiler: his daughter]] begins to cry. There's just something so sad about seeing such a sweet girl cry like that.

** Another Fridge Tear Jerker is that Finn says to Rasheeta that he's been searching for decades. The Tear Jerker is, Quilton is probably dead and [[spoiler: Finn's pillow family]] probably never got to see his last moments, even worse, finding out he was dead when they got home.

* [[spoiler:Bubble getting popped]] in "BMO Lost". Poor BMO is [[CryCute devastated.]]
** ''[[TheWoobie Oh dear God, the bubble!]]'' The subtext of the ComingOutStory is pretty groundbreaking for a kid's show, even if it is done through DoesThisRemindYouOfAnything [[spoiler:At least, [[SugarWiki/HeartwarmingMoments up until the ending.]]]]
-->[[spoiler:'''Air''': [[DoesThisRemindYouOfAnything I've been trapped in that bubble for so long, I've forgotten who I am!]] But now, I'm ''finally home!'']]
** Too bad [[spoiler:it becomes scary within seconds after that... though at least BMO doesn't seem to mind.]]
** Honestly, everything that happens after BMO and Bubble meet. From the look of it, BMO finally got a day where he met someone who always listened to him and was always there, even when he thought he was going to be alone, like right after BMO is forced to give up Ricky/Sparkle. He'd already been far from Finn and Jake for more than a day, and considering how few times he really shows up for an adventure, it was all typical for him to be alone, but not with a complete stranger. The final moment [[spoiler:Bubble shares with BMO right before getting popped just changed everything for BMO, and it's taken away from him like that. Even worse, Finn and Jake don't realize it and are too busy laughing at him.]]

** Braco. A self-imposed LoveMartyr who is [[spoiler:burned and then mutated into a monster by the demon Ogdoad at the end of the episode]] in order to win the heart of Princess Bubblegum. [[spoiler: And it doesn´t work]]. When he asks the Princess Bubblegum to marry him, he just sounds desperate.
--->'''Braco''': I paid the price for love, was it worth it? Do you love me? \\

** At the end of the episode, when [[spoiler: Braco leaves with P-bot, Princess Bubblegum drops a tear and says in a very sad manner: "You're welcome, my love".]]

* Most of "Be More" was an emotional roller coaster. First Finn and Jake having to rush a sick BMO to the Mo Factory (and BMO almost dying,) then happy Tear Jerkers as Finn thinks he met [[spoiler: another human]], and BMO meeting his ENTIRE FAMILY. It was so sweet that it's hard not to get misty-eyed when good things happen to these characters.

* "Frost and Fire"'s ending. [[spoiler: Flame Princess finds out Finn has deliberately been trying to get her to fight Ice King. And that he [[DidntThinkThisThrough used all the personal things she revealed to him]] in the letter. She's so upset that she can't even hear Finn's attempt at an explanation. And when she leaves, you can see in her posture and hear in her voice that she's not even angry. Just hurt. [[NiceJobBreakingItHero You blew it, Finn.]]]]

** Made worse in that in the next episode, Jake mentions that Finn and FP [[spoiler: broke up]].
* What happened to Lemongrab 2. He [[spoiler: is alive, but is horribly disfigured]]. He [[spoiler: has no legs, half of his head is gone, and he's extremely thin and tired-looking]]. Made worse by the fact that Lemongrab [[spoiler: constantly abusing him and yelling at]] him. '''THAT IS TERRIBLE!'''
** Lemongrab[[spoiler: 2's facial expression. He just looks so tired, run-down, hopeless, and subdued]]. And when Lemongrab [[spoiler: yells at him, the look on his face]] is heartbreaking. He just [[spoiler: looks so hopeless]].

** The episode is absolutely '''brutal''' if your favorite character happens to be Lemongrab 1. He went from being a crazy yet sympathetic JerkassWoobie to being irredeemably cruel and sadistic. While many fans are mourning for the loss of [[spoiler: Lemongrab 2]], many of these same fans were mourning the loss of their favorite character. There is probably no way that the writers can make Lemongrab 1 sympathetic and likable/relatable again. And that in itself is just sad, seeing as how many fans really ''did'' love the character immensely.

** The scene in the dungeon in which Lemongrab [[spoiler: eats Lemongrab 2]], and we see Lemongrab [[spoiler: 2's weak, emaciated arm limply disappear inside of]] him. It's ''heartbreaking'' because less than a year ago, we ''saw'' how much he [[spoiler: adored his little brother]]. It's also heartbreaking because of how [[spoiler: weak and sick Lemongrab 2 is from lack of food and from all the abuse]].
** "Lemonbrothers, stop! It has cost me much, but I have learned lemon need not squeeze lemon to survive! Lemonhope! Go forth, grow strong and return for us!" And right after this, [[spoiler: Lemongrab eats Lemongrab 2 alive]].

** Listen carefully to what the lemon children are saying as they hoist up Lemonhope. It's a bit hard to make out because of the shouting and speech impediments, but it's one word: [[spoiler: "Hope!"]] ''Gaaah...''

** The fact that in the episode, when Lemongrab is [[spoiler: eating Lemongrab 2 for the first time, Lemongrab 2's hand is clawing desperately at his back, trying to fight back]]... but he's too [[spoiler: weak and sick, and his hand goes limp and disappears]]...

* "Earth & Water" has the Flame Princess desperately trying to figure out how to "fix" herself, to the point that she's willing to let Bubblegum [[spoiler:lock her up and experiment on her]], accepting some not very comforting {{False Reassurance}}s just because she wants to ''trust'' her.
** Her reaction when she learns that [[spoiler:Bubblegum told her father to lock her up]].
** This is made worse by the {{Flashback}} to her past, showing how that arrangement came about: [[spoiler:After hearing that she'd become more powerful than him, the Flame King cast her out into the world hoping she'd die. She accidentally burned down her adoptive parent's cottage, then PB found her wandering around the woods (setting it all ablaze because she's a baby with no self-control), and brings her back home. Her reaction to hearing the Flame King say he doesn't want to deal with her possibly usurping him? "That's YOUR problem; either find a way to contain her powers or I'll do it myself."]]

* At the end of "[[WhamEpisode Play Date]]," [[spoiler:Keeoth kidnaps Jake and the episode... just ends.]]
-->'''Finn:''' [[spoiler:...Jake??]]
** Not only that, the fact that [[spoiler:Finn ends up having to break Joshua's sword. It's one of the only things he has to remember his dad by, and in the end it didn't even save Jake from being kidnapped.]]
* Both the beginning and toward the end of James. At first you don't know what's happened, but seeing [[spoiler:Finn and Jake so broken up really tears at you.]] Then when it's revealed what happened, it all just makes it even more heart breaking.
** Adding to that, [[spoiler:Cloned!James acts like he doesn't know who Jake was or what significance the coin Jake gave him was, even though it was his special coin from his non-cloned self]].

** First is the synopsis: [[spoiler:Ice King is restored back into Simon Petrikov by a badly-aimed magical spell, and manages to get Betty back with the help of Finn, Jake, and Marceline... but if he doesn't put the crown back on, he dies.]] Yep, everyone grab the tissues.
** When [[spoiler: Ice King first turns back into Simon, he doesn't think "yay, I'm cured!" but rather, "Oh, god, what new level of insanity have I reached?!?"]]
** [[spoiler:Betty hiding from Past!Simon around the street corner. The pain of watching Simon turn into a man she hardly recognizes and not wanting her last memories of him being insane, violent, and dangerous is just heartbreaking.]]
-->'''Betty:''' [[spoiler:Simon... don't leave me like this...]]
** [[spoiler:Simon practically begs Betty to not save him. He would rather die than [[AFateWorseThanDeath turn back into the Ice King]].]]
** And at the end of Betty, [[spoiler:Betty is seen at the end, watching the Ice King imprisoning Muscle Princess. Even though he survived, he no longer remembers her anymore. And with this context, the episode is arguably sadder than Holly Jolly Secrets, because now we know it's possible there's no way for Simon to be with his princess anymore.]] [[WesternAnimation/PhineasAndFerb I'm not crying, I'm sweating through my eyes!]]
*** [[spoiler:Alternately, it can be assumed that since Betty survived by the end and wittnessed Simon's resumed insanity, that she had retreated on the carpet not out of abandonment or despair, but out of the hope of finding some way to "fix" Simon and fulfill her promise to him of breaking the crown's hold for good. [[HopeSpot There is hope that there will be a]] HappyEnding.]]
** There's something very sobering about [[spoiler:the way Gunter just turns and looks stoically at an unseen Betty as she leaves on a magic carpet]] at the end.
* The ending of "Bad Timing." To sum it up: [[spoiler:LSP might have unintentionally killed Johnny, and in her state of grief she asks Bubblegum to use her time machine to make her forget her mistake. Bubblegum does so, but LSP is still in tears and might not know why. Also, if one looks carefully, Johnny appears in the episode's odd borders.]]
** Worse, the [[http://adventuretime.wikia.com/wiki/Adventure_Time_with_Finn_and_Jake_Wiki Adventure Time Wiki]] claims that the "odd border" might be an alternate dimension. So basically, [[spoiler: Johnny is not dead, [[TrappedInAnotherWorld but instead trapped in another dimension]] [[AndIMustScream with no known way out.]]]]
*** And even worse than that, [[spoiler:Johnny is ''aware of the events happening in the real world''. You can see his expression of shock and sadness as he sees LSP erase all her memories of him and revert back to the Jerkass she previously was, and ''there's absolutely nothing he can do about it''.]]

** [[spoiler: Lemongrab 2's HeroicSacrifice. He knew full well what would happen to him if his brother exploded while he was still in his stomach, but helped make it happen anyway, even passionately yelling encouragement for Lemonhope to keep playing the harp, because he so desperately wanted to liberate his children.]]

** The end of "Lemonhope Part 1", with the horrific and depressing image of [[spoiler: a badly dehydrated and starving Lemonhope falling face-down in the sand with his hair on fire.]]
*** [[spoiler:The fact that Castle Lemongrab has remained the same suggests that it did not undergo the technological progression the Candy Kingdom went through. Castle Lemongrab will always be a type of slum.]]
*** [[spoiler:Or that it was destroyed/depopulated shortly after [[{{jerkass}} Lemonhope]] left, and left empty.]]

* At the end of "Wake Up", [[spoiler: Prismo was KilledOffForReal by The Lich. Jake's grief is just... ugh.]]
** [[spoiler: Prismo died ''twice'', first when his body woke up and then when the Lich killed that too... And he was willing to die just so Finn could meet his horrible father.]]
** Notice that minutes before this happens, [[spoiler:the Cosmic Owl suddenly leaves in a hurry, with a [[IHaveToGoIronMyDog fabricated excuse about washing his feathers]]. While it could be said that he didn't want to become the victim of whatever cosmic crime Finn and Jake would need to perform, it could also be said that he foresaw Prismo's death and couldn't stand to watch his best friend murdered in front of his eyes. No wonder he was so insistent on one more game of Card Wars...one ''last'' game...]]
* At the end of "Escape from the Citadel" [[spoiler: after seasons of foreshadowing, Finn finally loses his right arm from trying to stop his father, who clearly wants nothing to do with Finn.]] The look of total defeat and heartbreak after everything that has occurred is heartwrenching. To put it in perspective, [[spoiler: for the entire show's run, Finn has been constantly wondering about his true origins and whether or not he truly is the last human being in Ooo, if not the entire planet. Now he has finally found his birth father, which is an opportunity to gain answers for every question he's had since he could talk, only to discover that the man is a selfish intergalactic criminal who claims he can't even remember what prompted him to abandon his newborn child in a forest. And despite that, Finn still wants to connect with him in some way, only to have the guy run off into the cosmos despite how hard Finn tried to hold on to him.]] The sullen look on Finn's face just screams how much he's still processing this. Poor unfortunate son.
** After the above happens, [[spoiler: Shelby comes out from behind Jake's ear and worms his way towards Finn, and starts silently crying, being the only one willing to fully give into the gravity of the situation at the moment. Also doubles as CMOH, considering how much of a series DeadpanSnarker Shelby is.]]
** Think about Jake during this. [[spoiler: He just lost Prismo, one of his best friends, and now the guy he considers his brother ''loses his arm'' trying to communicate with his deadbeat father.]] The look on his face is just as heartrending as Finn's: he doesn't know ''what'' to do or say and spends several minutes in complete silence.
** Now think about the reaction of everyone Finn knows when he returns to Ooo, [[spoiler: coming back with a nub of a right arm.]] That in itself is FridgeHorror for the rest of the characters, who have known Finn throughout the series as this WideEyedIdealist KidHero who is always looking out for others and tries his best at everything he does, never giving up. Just imagine yourself in the position to notice one of your close friends becoming back utterly depressed, heartbroken, and gravely injured like that.
** Tree Trunks [[spoiler: wanting a divorce]] from Mr. Pig feels needlessly sad, and despite the [[spoiler: Lich baby "changing everything"]], there's no evidence that things will be okay for the couple.
* In "The Tower," Finn is clearly having trouble learning how to function [[spoiler: with only one arm]], and is having to deal with the rage he feels toward his father. This rage actually manifests into a [[spoiler: prosthetic arm]] created from [[PsychicPowers telekinetic energy]].

** Don't worry, [[HappyEnding everyone gets to be happy in the end of the episode...]] [[FridgeHorror or so it would seem.]] Finn, [[spoiler:by regrowing his arm]] gets his flower detached. [[SugarWiki/HeartwarmingMoments Breezy happily receives the flower (the thing she obsessed over and tried to keep from wilting all along), which she proceeds to kiss.]] Anyone with a second-grader's education in biology knows that a picked flower ''is a dying flower.''

* "Something Big" has [[spoiler:[[KilledOffForReal Root Beer Guy's death]]]], defending the Candy Kingdom.
** Then there's the whole deal with the Giant Darren and the War Elephant, in a unusual tearjerker, we're presented with the realization that the only concept the two understand are fighting, nothing else; So now that they've been awakened for what can only be guessed as thousands of years; theyre confused about how the world has changed so much. It then makes them realize that they would better off be dead then live anymore since they have no desire to continue living without a purpose (except for the War elephant who [[spoiler: is trying to find a new one]]) To make it more clear, when Darren dies, he says "thank you" before he explodes, grateful that he no longer has to live in a world where he doesn't belong. Now that is a special kind of sad.

--> '''Flame Princess:''' "You're cold PB, and it’s not because you're a scientist or leader, it's because ''you are a bad person''. Something inside you is messed up girl, and whatever it is... '''sigh''', whatever."
--> '''Princess Bubblegum:''' "Alright, keep one last fire giant. I'm not a bad person... I want you to see that."

-->'''Jermaine:''' "You got to be Dad's favorite! [[WellDoneSonGuy I GOT STUCK WITH HIS MESS]]!"

* In "Grables 1000+", we see the land of Ooo in the distant future. One thing that sticks out about it is that while most of the planet is now devoid of life, [[spoiler:Marceline's house is still in good condition, with the lights still on]]. This implies that [[spoiler:Marceline is still alive after all these centuries, left alone in the world [[MayflyDecemberFriendship after having outlived all of her friends]]]].

** [[spoiler: In the same episode, Betty's mental breakdown after gaining the powers of the Magic Man and having a vision of Simon telling her "You forgot your floaties"; it also means that Simon may never be cured now that Betty, too, is insane]].

* A subtle one in "Orgalorg": after Gunter [[spoiler: reawakens as [[EldritchAbomination Orgalorg]] and sends a signal to his home planet]], Gunter snaps back to normal and smashes the wooden figurines he made to send the signal, [[MyGodWhatHaveIDone looking horrified at what he's just done]]. This could mean that "Gunter" has developed his own personality, and is terrified of going back to [[spoiler: his old self]].

* [[spoiler: Moe's death prior to the events of "The More You Moe, the Moe You Know".]]

* In "King's Ransom", Ice King comes ''this close'' to remembering [[spoiler:Betty's name]].

** And then, at the end of the episode [[spoiler:the crystal housing the Finn Sword's Finn gets impaled by the grass sword, and Finn the Human faints.]]

** The revelation that Martin [[spoiler: was a genuinely loving husband and father that [[PapaWolf did his best to protect his son]], even going against the unstoppable Guardian]]. Neither Finn nor Minerva will ever know the lengths that Martin went to for his child, both believing him to be nothing but a self-serving {{Jerkass}} to his final moments.
*** It's quite likely that Martin wound up like he did when Finn met him as a result of [[spoiler: injuries he received from fighting the Guardian, as promo art for the episode shows him with severe bleeding from a ''piece of shrapnel'' that landed in his head.]]
*** The last words that Martin says to [[spoiler: Finn before they're separated]]:
--> '''Martin''': [[spoiler: Finn... I'll be back for you.]]
** Worse still, [[spoiler: he ''winks'' when he says this. When he loses Finn and is thus unable to keep his promise, he believes he lied to his son and from that point onward only ever winks when he is lying, because that's what he associates the gesture with in his mind. To sum it up, losing Finn ''broke'' Martin, irreparably.]]
* [[spoiler: While Finn does finally get to meet his mother, it takes a turn for the sadder after it's revealed that she only exists as a consciousness inside a computer and an army of helper robots in her likeness. She even has to tell one of the bots to hug Finn, not being able to physically touch him...]]
* [[spoiler: Susan/Kara is finally reunited with Frieda, only to find that she's completely given up on her dreams of adventuring (possibly due to the "re-education" she was put through). Even Kara reminding Frieda that she was the one who ruined her chances of leaving barely gets a response. Thankfully, Frieda snaps out of it after hearing Finn's pep talk.]]
** [[spoiler: Minerva has clearly suffered SanitySlippage, wanting to keep Finn with her by forcibly performing the same BrainUploading procedure on him that she went through. But it's clear that this is rooted in an incredibly real fear of losing him again if she lets him return to Ooo.]]
* [[spoiler: The last minutes of the special, when we see Finn saying goodbye to his mom, and crying when her signal can't reach him anymore]]

* Lumpy Space Princess's {{Heroic BSOD}} after finally realising that nobody is the person they used to be is fairly distressing in it's own right. Everyone in the land of Ooo has basically become either a sad, lazy, angry or sweet shadow of their former selves except for LSP and three others, [[ClassicalAntiHero and she bemoans her ineptitude and inability to save anyone all on her own]] when even Finn falls to the influence of the elements. [[spoiler: Of course the fact that her immunity is the key to saving Ooo is what ultimately makes her heroic action at the end of Elements so SugarWiki/{{heartwarming|Moments}}.]]
* Betty's frustration with Simon reaches a breaking point where she tries to recreate a restaurant they used to go to to jog his memory, but of course, it doesn't work. She suffers a breakdown and confides to Tiny Manticore about it before coming to the realization that Simon may just not exist anymore, and that she should try to accept Ice King as he is. She tries, and the two begin to get along just fine throughout Elements. [[spoiler: Despite it all, she just cannot accept Ice King, and leaves Finn to be corrupted by the Candy Kingdom while she steals their only chance of fixing Ooo in an attempt to go back in time and stop Simon from ever getting the crown]].

* In "Three Buckets", [[spoiler: Finn ends up accidentally murdering Fern after the Emissary From Beyond makes him try to imprison Finn. Just the look on Finn's face afterwards, and his silent return to the tree house is enough to make anyone weep.]]
** Made even worse in the very next episode, when it turns out that Finn feels so much guilt over what he had to do that he can't attack a monster that's killing the Banana Guards... he just sees [[spoiler: Fern's]] face when he tries.
** [[spoiler: Hell, just Fern's story in general. Way back in "Two Swords" he was confused and thought he was Finn, because he ''was'' Finn. From his perspective he simply woke up one day to find another person wearing his face, only to find out that that person was him and ''he'' was the copy made out of plant matter. Suddenly, even his own brother shies away from him, and all of his friends and people he used to know treat him like another person, when to him he was just ''Finn''. To top that off he's now made of grass, leaving him unable to perform his favorite hobbies or even enjoy food, ''and'' he's faced with a series of dramatic failures as a hero that cause him to develop an intense inferiority complex to Finn. Is it any wonder he broke down?]]

** Both Finn and Jake are at their lowest points emotionally as they find themselves helpless against the presence of [[spoiler:GOLB]].
*** Jake in a particular way is far beyond broken: still upset at seeing [[spoiler: Finn devoured by GOLB, he gets to see one the Treehouse destroyed with BMO inside, possibly killing the last living member of his extended family/gang and every single memento of their lives in one swoop. Jake is left literally speechless, then curls into a sobbing ball as he becomes increasingly smaller]]
*** The worst part of it? [[spoiler: When BMO shows up, alive but with a cracked faceplate, Jake keeps berating himself because, from his point of view, he just let Finn die, the threehouse being crushed into oblivione and BMO being hurt. BMO's reaction? He hugs the now smaller Jake singing him ''Time Adventure'' as a final lullaby to let him sleep one last time before the possible end]]
--> '''BMO''': [[spoiler: "Let me be the papa..."]]
** [[spoiler: As Finn, Simon and Betty are being slowly crushed to death inside GOLB, Finn tries desperately to use the Ice Crown to break out of the room they are held in only to finally collapse from exhaustion as the walls slowly close around them. All Simon can do is put a hand on Finn's shoulder to console him [[FaceDeathWithDignity as they await the end.]]]]
--> '''Finn''': [[spoiler: "I always figured I'd go out saving somebody..."]]
--> '''[[spoiler: Simon:]]''' [[spoiler: "Hey, nobody gets to choose how it happens. The only important thing is that we're here together."]]
** [[spoiler:Betty's HeroicSacrifice, letting herself get absorbed by GOLB as she uses the wishing crown to keep Simon safe. She ends up taking over GOLB's consciousness, leaving and saving Ooo. As she leaves, Simon breaks into tears as he begs his "princess" to come back.]]
*** [[spoiler: A brief, but heartbreaking moment during the ending montage shows that Simon travelled all the way to Prismo's time room to wish Betty back... only to end up with a [[CallBack trash]] [[Recap/AdventureTimeS6E38YouForgotYourFloaties can]] on the floor.]]
*** Before [[spoiler: Betty leaves, she disintegrates both of GOLB's monsters. Except said creatures were actually corrupted candy people, who were still alive and sentient while [[AndIMustScream unable to control their bodies]]]].
*** Arguably, you could apply "Time Adventure" to [[spoiler:Simon and Betty. The time they had together always came with some sort of catch, and now, Betty has saved her love and everyone at the cost of ever seeing them again, and she will never be able to join Simon in death. All they have now is their memories and love of each other. They could never return to the old times they had before the Mushroom War.]]
** [[spoiler: Finn and Jake's treehouse getting destroyed.]]
** [[spoiler: Due to Finn killing the [[SoulJar Grass Demon]], Fern slowly begins to disintegrate until he dies shortly after Betty-GOLB leaves, finally at peace with himself. His last request is that Finn and Jake plant his remains at the now ruined treehouse.]]
*** Even worse: [[spoiler: Fern isn't aware of the ruination of the treehouse, and his first request is being able to see it one more time before dying. As Finn rushes to reassure him he will help, Jake looks at both of them shivering and horrified, unable to break them the news. Only when Fern tells them that's too late, and he'd rather get the last seed of himself planted near the treehouse, Jake calms down]]
** Even after the happy ending, [[spoiler: an apparently calm and accepting Jake is able to see and interact with the Music Hole. If you remember the lore, the Music Hole can be seen only by people with childlike innocence, like Finn and BMO, or with great loss in their heart, like the Ice King, could see her. Jake will never let the loss of Fern and the treehouse go, no matter how much time will pass]].
** The peek forward in time showing [[spoiler:even BMO isn't immune to TheFogOfAges. He remembers the story, but has forgotten Finn's name after so many centuries.]]
*** In the intro, we briefly see [[spoiler:fallen, eroded statues of Finn and possibly Jake. A nearby sign says that these statues are of "Finn and Jer—", implying something happened to Jake that caused Jermaine to take his place. And the fact the Finn statue depicts him as young can either mean two things: that was considered his prime, and/or Finn died young.]]
*** The Ice Thing is suddenly a sadder figure after the ending montage shows why he may be acting that way. [[spoiler:His left eye gem was on [[LostLenore Turtle Princess's]] wedding ring that he proposed to her with. A thousand years later, Gibbon has it, Turtle Princess's fate is unknown, and the Ice Thing is a maniacal animal-like creature that seems to constantly attack Gibbon and the Pup Kingdom so he can have his gem back.]]
*** AllThereInTheManual revealing that [[spoiler:Beth is a fugitive from her own kingdom, and Gibbon is a tyrant that strips away his fellow pups' powers at birth all because he lost his own power. It's sad to see that this is what has become of Jake and Lady Rainicorn's Legacy.]]
*** AllThereInTheManual revealing that [[spoiler:Gibbon misses his mother, Charlie.]]

* The ending of the ''Fionna and Cake'' comics reveal the Ice Queen's origin. [[spoiler: It's just as heartbreaking as Ice King's. She used to be a kindly water nymph who became friends with the young Cake. She was fatally wounded one day and [[EmergencyTransformation to save her]], Cake gave her a magic gem she found. It turned out to be part of Ice Queen's tiara and it turned her into the Ice Queen, just like the Ice King's crown did, with the same Alzheimer's-like effects and everything.]] As if that isn't sad enough, [[spoiler: the issue ends with Ice Queen melting herself as she explains that she did everything she did because she thought it would bring her warmth. There's an implication that Ice Queen has been actively suicidal for many years now...]]

*** [[spoiler: After losing the love of his life, as well as who knows how many other loved ones, surviving the apocalypse, slowly going insane with no way to help himself, having to abandon a child in fear that he might hurt her and ending up as a pathetic shell of his former self, Simon Petrikov]] [[DeathSeeker JUST. WANTS. TO. DIE.]]
* [[spoiler: The Lich's]] LotusEaterMachine. It's basically YankTheDogsChain ''times a thousand.''
--> '''Ice King:''' [[http://chuck-charles.tumblr.com/post/59332968769/reminder-that-in-the-adventure-time-comics-finn You're just as real as I--]] *[[spoiler:[[LiterallyShatteredLives Fake!Betty shatters into a million pieces]]]]* [[TheLostLenore --as I remember.]]
** [[spoiler:Fake!Betty's]] writing on the sign that she made. Remember, this is the universe where the Ice King has his one true heart's desire granted.

* [[http://abarero.tumblr.com/post/59154069126/can-we-just-talk-about-this-panel-can-we-talk The Ice King doesn't even remember]] why he's [[spoiler: fighting off the crown anymore. Remember all that stuff from the entry above where he JUST WANTS TO DIE? Yeah, remember the crown wants [[KillEmAll EVERYBODY to die.]]]]
* [[spoiler: What happened to the first Ghost Princess after the events of "Ghost Princess". Turns out Clarence really was a donkus.]]
* [[spoiler: The fact that Root Beer Guy is starring in the Banana Guard Academy mini-series, considering he recently died in the line of duty in "Something Big".]]

* In the [[TheProblemWithLicensedGames otherwise uninspired]] licensed game, ''Explore The Dungeon Because I Don't Know'', a horrifying bit of light is shed on just how far Princess Bubblegum is willing to go [[ForScience in the name of science]]. The game revealed that after the events of "You Made Me," Princess Bubblegum [[spoiler: lured both Flame Princess and the Lemongrabs into a secret lair so she could experiment on them. When the earls recount their horrifying tale to the dumb-founded Finn and Jake, they mostly seem confused and uninterested in the earl's plight. Finn and Jake proceed to fight them, the Lemongrabs lose, and then they ask for candy.]] No wonder they wanted Finn to give them candy after that horrible ordeal... poor things...
