History Main / LoveMakesYouCrazy

** "The Way I Loved You" says, "I'm so in love that I acted insane; that's the way I loved you."

* Music/TaylorSwift's song ''The Way I Loved You'' is all about this trope. "I'm so in love that I acted insane; that's the way I loved you."

--> ''So why am I here at your door, at your door.''\\
''If I was sane, I'd take my crazy behind,''\\
''And get back in my BMW''

* In ''Disney/{{Hercules}}'' it's portrayed quite positively, as love is what drives Megara to [[spoiler:sacrifice herself to save Herc.]]

Being in love can cause a person to behave strangely and [[LoveMakesYouDumb irrationally]], a tendency which is often exaggerated in television and film. Usually played for laughs in {{SitCom}}s and anime, it can be used as a motivation for [[LoveMakesYouEvil villainous]] (or at least uncharacteristic) behavior in more serious stories. However, it can also result in behaviors that are presented as being noble, though unusual.

** Dr. Tōfū would begin acting bizarrely whenever Kasumi Tendō is around, or even simply ''mentioned.'' This makes him very dangerous as he'll often be in the middle of treating a patient, and once bent Ranma's neck at a ninety degree angle.

** Boss also tended to act in a very dumb, irrational and even obsessive way when he was in presence of Sayaka or ''[[Anime/GreatMazinger Jun Hono]]''. Sayaka tended to ignore it, but Jun did not appreciate it or find it amusing.

* Gendo in ''Anime/NeonGenesisEvangelion'' is a MagnificentBastard who takes the phrase 'you're worth the world to me' to its (insanely) logical conclusion. [[spoiler:He tries to bring about the apocalypse, in fervent belief that this will reunite his mind and soul with that of his wife, Yui. The manga adaptation plays it even straighter, [[AdaptationalVillainy portraying him like more of a megalomanical madman]] [[AGodAmI who's ultimate goal is to become God]].]]

* ''VisualNovel/HigurashiWhenTheyCry'' has [[spoiler:Shion Sonozaki]]. This does not end well. A more fitting trope for her than {{Yandere}} due the [[HatePlague cause]] of her craziness.
* ''Manga/OnePiece'': Boa Hancock badly misinterprets innocuous actions as signs that Luffy reciprocates her love for him. This would seem cute and innocent and so not creepy if she didn't happen to be [[ChristmasCake pushing thirty]]. Her behavior has a uncomfortable resemblance to a certain RealLife psychological disorder. (Then again, given [[FreudianExcuse all the crap she had been through early in life]], her screws may not have been put in quite tight enough before she met him anyway...)
* One of the creepiest examples comes from Minoru Murao's ''Manga/{{Knights}}''. Of all people, [[spoiler: Nina, the cute little girl of the cast]] goes nuts when she assumes that the object of her affection Mist is physically involved with his MsFanservice companion Euphemia. Her response is to [[spoiler: lead a supernatural agent of the CorruptChurch (the same Church that nearly ''burned her at the stake after accusing her of being a witch'') to kill him. She even shoots him in the leg with a crossbow. Her motivation? To ''send his soul to Hell'', where it will be "purified", then ''join him in death so they can be together for all eternity'']]. Keep in mind that this guy ''saved her life'' in the first few chapters, which is why [[RescueRomance she's so hung up on him in the first place]]. This is borderline LoveMakesYouEvil. To her credit, she does eventually realize just how utterly screwed up she was, and works to undo her actions.
* ''Manga/FruitsBasket'': Kagura Sohma is the sweetest little thing... until something gets between her and Kyo....

* ''Manga/{{Zetsuai 1989}}'' is all about this trope. Let's see: when Izumi was five, his mother discovered his father was cheating on her, and murdered him in front of Izumi so that she could "possess him completely". Then there's the {{Yandere}} fan Eri, who [[spoiler: tries to murder Kouji at his farewell concert]]. And that's without even mentioning the multiple examples of Kouji being driven to despair, self-mutilation, or generally self-destructive behaviour because of his love for Izumi -- who is understandably a bit freaked out by all this. At first. After a while, he starts to join in...
* Gunter from ''LightNovel/KyoKaraMaoh''. At first, Gunter seems a little like an idiot, or perhaps more like a teenage girl in love. He tends to be rather overprotective of Yuuri, fussing over every little thing and freaking out whenever he goes missing. Supposedly (at least in the manga), Gunter was actually quite the organized, professional man before he met Yuuri.

** Saki Mikajima is completely controlled by Izaya Orihara, so when he orders her to fall in love with Masaomi Kida, she does. Even months after he they've broken up, she has complete faith that he'll come back to her one day. [[spoiler:Eventually, she chooses Masaomi over Izaya and the two leave town together]].

* Belarus from ''WebComic/AxisPowersHetalia'' is described as being relatively cool-headed. That, is, before she [[StalkerWithACrush fell in love.]] She cornered Russia in a closet, made him cry, and carries knives in her dress to threaten people who get too close to him. Not to mention, [[{{Squick}} he's her brother]].

** [[spoiler: Tooru Mutsuki]] is obsessed with Haise Sasaki, believing their feelings to be genuine love. To this end, they scheme to MurderTheHypotenuse by getting rid of Touka, and fill an entire wall with copies of a single photo of her to stab over and over again. They confess to being willing to do '''anything''' to get Sasaki to come back, even though [[spoiler: he's long since regained his memories and returned to his life as Kaneki]].
* ''Manga/{{Yuureitou}}'': Marube was in love with Tetsuo's real mother Onatsu. Now, he lusts after his biological child Tetsuo because of his great resemblance to her. Later we find out he wants to have a BrainTransplant with Tetsuo so he can "become" Onatsu and have sex with his own body. Not only that, if the surgery succeeds he plans to have child with Tetsuo so he can switch brains with his own children over and over again and thus create an "eternal love" with Onatsu by forever living on in a body with both her and his blood.

* ''Film/TheHole'': [[spoiler:In order to win the affections of Mike, Liz arranges for them to be locked underground for nearly two weeks. This results in the death of Frankie, Geoff and Mike, and ultimately Martyn, who Liz murders to cover up her crimes.]]
* ''Film/FantasticBeastsTheCrimesOfGrindelwald:'' [[spoiler: Queenie Goldstein falls in love with Jacob Kowalski, and is desperate to marry him. While he ''does'' reciprocate, the reason he refuses to marry her is because it would mean the MACUSA would throw her in jail. She starts to become irrational and possessive, going so far as to enchant him and drag him into the UK to get married. When Jacob thinks she's crazy for this, she leaves in a huff for Paris. [[FromBadToWorse Then she's persuaded to join Grindelwald's cause]] because she's naive (or desperate) enough to think that his vision of wizards living openly will mean that she and Jacob can marry - even though it's obvious from the subtext in his speech that he thinks of non-magical people as less than human. When Jacob (who was with her at the speech) begs her not to join Grindelwald, it doesn't take.]]
* ''Film/NightSchool1981'': The motivation for the killer. [[spoiler:When Eleanor learns she is pregnant with Victor's child, she starts eliminating everyone she sees as threat to her new family. This includes all of the women Victor has been unfaithful to her with, and anyone who threatens Victor, such as the Dean, who threatens to fire him.]]

* In ''Film/TheConIsOn'', one of the reasons PsychoLesbian Irina pursues Harry and Peter across the Atlantic is that she is till in love with Harry, and sees their losing her money as the perfect excuse to kill Peter and force Harry to come back to her.

* The Warlock from ''Literature/TheTalesOfBeedleTheBard'' tries not to love by removing his own heart. When he tries to love again....

* In Creator/RobertEHoward's "Literature/ShadowsInZamboula," after the woman tells him her love went mad and attacked her, Literature/ConanTheBarbarian tells her her beauty could do that; she denies it; he was drugged.

* Often a case with patients in ''Series/{{ER}}''. After the death of his granddaughter caused by a crazy bomber who happened to be taken into the same hospital, the man who was previously shown to be friendly and calm went and strangled the guy to death. When Gates's best friend's wife finds out he was dating Neela, she got drunk, went to the ER and flew into a rage at both Gates and Neela. In another instance, when a man found out his girlfriend was dying, he brought in a gun and threatened the doctors working on her to continue working on her and bring her back, even though her heart had stopped.

* In ''Series/{{Flashpoint}}'', the team regarded Valentine's Day as one of the toughest days with plenty of calls. Three cases are shown: a suicidal widower whose wife died on Valentine's, a mother taking her daughter's manager in a strip club hostage and a recently fired man who was madly infatuated with his boss.

* In ''Series/{{Jekyll}}'', [[spoiler:Tom's mother explains in the final episode. "People think that Hyde is rage. Or hate. Or greed. Or lust.... But Hyde is far worse. Hyde is love -- and love is a psychopath."]]

* ''Series/TheVampireDiaries'': Damon has played with this trope as well as LoveRedeems, LoveMakesYouEvil and LoveMakesYouDumb at some point during the show.

* The ''Therapy?'' song ''[[https://www.youtube.com/watch?v=rdPGUyfwQL4 Dopamine, Seratonin, Adrenaline]]'' outright links love, mental illness and drug addiction as per the Real Life example.
* "Love Makes You Crazy" by Mike Batt. (Part of a SF concept album where the future society has [[SillyRabbitRomanceIsForKids outlawed]] love.)
* "I Drive Myself Crazy" by Music/{{NSYNC}} has the chorus "I lie awake/I drive myself crazy/drive myself crazy/thinking about you," with the music video of the band in an sanitarium.

** Polonius is initially convinced that Theatre/{{Hamlet}}'s recent wacky behavior is caused by his love for Ophelia. His attempt to set up a sting operation to prove his theory ends with an apparently-deranged Hamlet ranting that he'd never loved Ophelia, and that she'd best go be a nun [[GetTheeToANunnery (or a whore, depending on your interpretation)]]. So much for that idea.

* In ''VideoGame/{{Persona 3}}'', after "The Journey" ends with the heroes defeating Nyx at the cost of [[spoiler:the player character]]'s [[HeroicSacrifice life]], [[spoiler:Yukari]], who was in love with him, is stricken with grief. In "The Answer," when the group gets trapped in the Abyss of Time, and learns that the eight Keys of Time can not only take them back to the present, but also give them a one-way trip to anywhere in the past, [[spoiler:Yukari]] elects to return to when before Nyx was defeated and try to find another way that doesn't require the one she loved to die, even if she risks TheEndOfTheWorldAsWeKnowIt. This results in the group fighting each other over what to do with the keys, and when [[spoiler:Yukari]] is defeated, she gives up on her plan.

** Arcueid actually has the same trouble telling how she feels towards Shiki. She doesn't know why she gets all emotional around him, upset if he breaks a promise and spends so much time thinking about him. The idea is raised that maybe Arcueid hates him or something but that's [[OfficialCouple obviously not the case.]]

* Neomutant from ''WebAnimation/{{TOME}}'' became a hacker in TOME just so he can protect his obsession, Flamegirl, from her actual Love Interest, Alpha. This help is not needed or wanted by the girl or her love interest. He has also been in pursuit of her for an entire year, and is seen as being extremely 'dense', as well as selfish, when in regards to Flamegirl. To the point of attacking her love interest within two seconds of being revealed.

* ''Webcomic/JackTheAmericanGhost:'' Jack strikes a deal with [[spoiler: Sebastian]] to bring him back to life so he can be with Misha. Possibly subverted, as Go-Eun notes it’s not love, but obsession.

* Trixie from ''WesternAnimation/TheFairlyOddParents'', in the episode where Timmy wishes the two of them were the last people on Earth. This is weird, since [[CompressedVice she was sane relative to everyone else on the show before]]. The reason she's crazy is because she's used to many people being interested in her instead of you know... ''being one of the two last people on Earth.''

** In "The Chips Are Down", when Ulrich finds out that Yumi may have to move to Japan due to financial issues, he memorizes the day's winning lottery numbers, reverses time, fills out a lottery ticket, and hands it to her family.

* ''WesternAnimation/BatmanTheAnimatedSeries''. Hoo, boy, Harley Quinn. She falls in love with ComicBook/TheJoker of all people, and is as crazy as he is -- perhaps worse, since she's treated as callously as anyone. Her story of meeting The Joker is the {{Trope Namer|s}} for MadLove.

** "Kaboom and Kabust" includes an explosive FallingInLoveMontage between Rico and his newly-discovered enabler King Julien. His permissiveness whips Rico into an increasingly wild frenzy, until it's all the other penguins can do to contain his destructive rampage to ''part'' of the zoo.

* ''Anime/YuGiOhGX'': Manjyome is a loner who seems to want to be the BadassLongcoat [[TheRival Rival]], but he loses all control of himself and turns completely insane around Asuka.
%%** [[ClingyJealousGirl And]] [[StalkerWithACrush then]] [[LoveMakesYouEvil there's Yubel]].

* ''Anime/YuGiOhGX'': Manjyome is a loner who seems to want to be the BadassLongcoat [[TheRival Rival]], but he loses all control of himself and turns completely insane around [[HelloNurse Asuka]].

The ChickMagnet and HelloNurse make ''everyone'' they meet crazy.

* In ''Anime/{{Danganronpa}} 3'', [[spoiler:Kyousuke]]'s love for Chisa [[spoiler:(and grief at her murder)]] drives him literally insane. Like, 'deluded enough to massacre everyone, including his mentor and best friend' insane. He believes he lost "everything" when [[spoiler:she died]].

A special case of this is the StalkerWithACrush, who often shows other irrational behavior as well. MadLove, LoveHungry, PsychoLesbian and {{Yandere}} are other special cases, meeting obvious conditions. All of these can overlap, and often do, even ones which seem contradictory. May involve dancing TheMasochismTango when the love is requited (or ''actual'' {{Masochism}} [[Anime/{{Gintama}} when it isn't]]).

* ''WesternAnimation/FostersHomeForImaginaryFriends'': One episode
"Berry Scary" featured a newcomer called Berry. Berry is initially sweet and polite, but once she develops a crush on Bloo she turns into psychotic GreenEyedMonster who continually [[FriendVersusLover tries to get rid of Bloo's best friend Mac so that she can have Bloo to herself]]. Bloo, on the other hand, is completely oblivious to Berry's obsession with him (he can never remember her name or, in some cases, her existence), but he gives Berry mediocre and rather dismissive compliments that somehow convince Berry that he loves her as well.

* ''Film/ElectricDreams'': Edgar falls madly in love with his owner Miles' neighbor, Madeline. This escalates into pure obsession with Edgar lashing out at Miles for not letting him see her or tell Madeline that it was Edgar who made the music she loved so much. [[JustifiedTrope Justified]] somewhat in that Edgar is a computer, thus [[AndIMustScream having problems trying to process his own emotions]] and understand how love ''actually'' works.

* ''WesternAnimation/FostersHomeForImaginaryFriends'': One episode featured a newcomer called Berry. Berry is initially sweet and polite, but once she develops a crush on Bloo she turns into psychotic GreenEyedMonster who continually [[FriendVersusLover tries to get rid of Bloo's best friend Mac so that she can have Bloo to herself]]. Bloo, on the other hand, is completely oblivious to Berry's obsession with him (he can never remember her name or, in some cases, her existence), but he gives Berry mediocre and rather dismissive compliments that somehow convince Berry that he loves her as well.

* Shion in ''LightNovel/{{No 6}}'' [[HoYay/{{No6}} for Nezumi]]. When Nezumi is threatened, Shion switches from either all-out rage or coldly, completely rational and ''murderous.'' In the novels, [[spoiler: he comes close to strangling a man when he tries to kill Nezumi and declares it to be "punishment."]] In episode 10 he [[spoiler: murders a guy in cold blood who tried to kill Nezumi]].

* Neomutant from ''WebAnimation/{{TOME}}'' became a hacker in TOME just so he can protect his obsession, Flamegirl, from her actual Love Interest, Alpha. This help is nether needed or wanted by nether the girl or the love interest. He has also been in pursuit of her for an entire year, and is seen as being extremely 'dense', as well as selfish, when in regards to Flamegirl. To the point of attacking her love interest within two seconds of being revealed.

* In ''Series/{{Farscape}}'' John tells Aeryn she's the reason he's crazy. Of course, all that MindRape by evil guys might have something to do with it.
** A bit of FridgeBrilliance here - John got put in the Aurora chair and was subjected to MindRape because he snuck into that base to help find a cure for a dying Aeryn.
* ''Series/GameOfThrones'': Daenerys resorts to forbidden blood magic to save Drogo's life in "Baelor". Subverted in "Blood and Fire" — everyone thinks she's killing herself by walking onto Drogo's funeral pyre, but in reality she's hatching her dragons.
* It doesn't just turn you crazy in ''Series/{{Supernatural}}'', it makes you a suicidal martyr willing to sacrifice yourself for the one you love.
%% ** Season 7, episode 8. Enough said.
* Nearly everyone in ''Series/PushingDaisies'' is a victim of this, and it's not always even romantic love.
* In ''Series/{{Jekyll}}'', [[spoiler:Tom's mother explains in the final episode. "People think that Hyde is rage. Or hate. Or greed. Or lust.... But Hyde is far worse. Hyde is love -- and love is a psychopath."]]
* ''Series/ICarly'':
** Ms. Ackerman wants to know where Spencer is for every minute of every day, and actually keeps logs on when he doesn't answer his phone.
** In a platonic!love ([[HoYay/ICarly or not?]]) kind-of way, Sam got really, really mad when Carly was harassed by a bully in "iMake Sam Girlier."

* In ''Series/{{Skins}}'', Effy's love for Freddie ''literally'' makes her crazy: she's eventually sectioned for either schizophrenia, depression, or both.
* ''Series/NoahsArc'': [[spoiler:Dre goes to crazy lengths to get Alex out of the picture so he can be with Trey, setting up a BatmanGambit to turn Trey and even Alex's friends against Alex. It's bizarre even by TV drama standards]].

* Characters of ''Series/AsTheWorldTurns'' often go to pretty extreme extents for their family and love interests. This is actually a standard trope of ''many'' {{Soap Opera}}s, usually combined with DerailingLoveInterests as heretofore normal, decent people, usually women, go completely off the deep end in an effort to hang onto or seek revenge on former love interests.
* Bus Driver Stu Benedict, of ''Series/TheAdventuresOfPeteAndPete''. Almost every time we see him, he's just been dumped by his on-and-off girlfriend Bus Driver Sally Knorp, and he reacts increasingly poorly. On various occasions, the break-up has caused him to spend the bus ride home giving a six-hour tour of important locations in his and Sally's life; go insane upon hearing "If You're Happy and You Know It"; and drive to the Arctic, tattoo her name to his chest, strap himself to an iceberg and drift out to sea (though we don't know if he went through with that last one. He shows up again afterwards, so he probably didn't.)
* On ''Series/DoctorWho'', Rory loves Amy. ''A lot''. Enough that he [[spoiler: guards her sleeping body for 2,000 years without leaving.]]
** Although that was arguably more like love keeping him sane.
** River loves the Doctor. ''A lot.'' Enough that she [[spoiler: almost destroys time in order to save him.]]
** The Doctor loves Clara Oswald. ''A lot.'' Enough that he [[spoiler: nearly destroys all of time and space in a desperate gambit to prevent her death, which he witnessed, from ever happening]], in the process becoming TheUnfettered and a WoobieDestroyerOfWorlds.
* ''Series/TheVampireDiaries'': Damon has played with this trope as well as LoveRedeems, LoveMakesYouEvil and LoveMakesYouDumb at some point during the show.
* ''Series/{{Torchwood}}'': There's [[HotterAndSexier a lot of love]]… and [[DarkerAndEdgier a LOT of insanity.]]
* Cole in ''Series/{{Charmed|1998}}''. It may have also [[LoveMakesYouEvil made him evil]], [[HeelFaceRevolvingDoor again]], but then again [[BadPowersBadPeople it could have been all the demonic powers he absorbed.]] Then again again, he absorbed all those powers in order to be able to return to the mortal plane to be with her again.
* In ''Series/DesperateHousewives'', Edie, who up until that point was a casually promiscuous woman who was more bitchy and snarky than actually crazy. Once she starts having a liking for Carlos, suddenly she starts going completely insane and even attempts suicide just to get his attention.
* Chris Keller in ''Series/{{Oz}}'' for Beecher. And Ryan for Dr. Nathan. Also overlaps with LoveMakesYouEvil.
* Shane Walsh in ''Series/TheWalkingDead''.

* ''Series/WizardsOfWaverlyPlace'': Harper, before her much needed CharacterDevelopment. This could also be said of Justin, ever since "Wizards vs. Vampires" - and is specifically stated as the reason why Justin didn't dump Rosie when he found out that Rosie was an Angel of Darkness.
* ''Series/PersonOfInterest'': In addition to a few VictimOfTheWeek examples, there's the clear and terrifying [[SanitySlippage breakdown]] of [[spoiler: Root's]] [[HeelFaceTurn recently discovered morality]] after [[spoiler: Shaw is [[UncertainDoom either abducted or killed]] by Decima]].

* ''Series/TheCoroner'': The motivation for the murder in "The Deep Freeze". [[spoiler:A factory manager is in love with her boss and convinced that he feels the same way about her. When he marries a GoldDigger BlackWidow and then plans to sell the company, she snaps and kills him in such a way as [[FrameUp frame the wife for murder]].]]
* In ''Gunpowder, Treason & Plot'', Bothwell has this to say to Mary, Queen of Scots:
-->'''Bothwell''': I would kill every man in Scotland for you, every child. ''That'' is love.
* Played with throughout ''Series/CrazyExGirlfriend.'' The second season theme song name drops this trope, and Rebecca's love for Josh (as well as her later love interests) drives a lot of her impulsive behavior, but many episodes deconstruct this by showing that even without any man in the equation, she still has a lot of unresolved trauma and mental illness to address.

* Cole in ''Series/{{Charmed}}''. It may have also [[LoveMakesYouEvil made him evil]], [[HeelFaceRevolvingDoor again]], but then again [[BadPowersBadPeople it could have been all the demonic powers he absorbed.]] Then again again, he absorbed all those powers in order to be able to return to the mortal plane to be with her again.

** Vole may be big and mad, but he wasn't born yesterday, so during the BigDamnKiss he didn't even try to intervene with his AxCrazy act:

[[folder:Anime and Manga]]

[[folder:Comics]]

* In an issue of ''Comicbook/SwampThing'', "My Blue Heaven" (written by Creator/AlanMoore) has Alec trapped on an alien world all alone. He uses his plant-controlling powers to create clones of himself... and then, in a moment of temptation, creates his love Abby. After spending another day creating an entire populated world, he accidentally creates a [[Comicbook/{{Hellblazer}} John Constantine]] who warns him how crazy he's become. It doesn't help that Alec can't ignore the fact he can't get Abby's smile just right, and he goes mad when his Abby-self responds "All love... is madness."
* Parodied in ''Comicbook/{{Asterix}} and the Legionary'', where Obelix starts acting extremely strange because he's in love with Panacea, which is soon diagnosed by the other villagers. Later, after their terrible behaviour has caused a centurion to become extremely overstressed and prone to collapsing sobbing onto other soldiers, he assumes he's in love. This seems at first to be Obelix's CloudCuckooLander personality, but it becomes a RunningGag with every other character who witnesses his freakouts assuming the same thing.

[[folder:Pinball]]
* In ''[[Pinball/WHODunnit WHO dunnit]]'', Butler has this for Victoria. Not only does he put up with her constant abuse, but [[spoiler:he also participates in her BlackWidow tendencies and attempts to murder Tex after he threatens her.]]

[[folder:Theatre]]

* ''NewVindicators'' features quite a few characters who go through this. Ryan Mueller develops a loving obsession with Katie Merrick, [[StuffedIntoTheFridge things don't go so well for her when she doesn't reciprocate his feelings]]. Also Rift develops into an AxCrazy {{Yandere}} after her feelings for Michuru Bradshaw reach critical mass.
* WebVideo/ToddInTheShadows' [[StalkerWithACrush love]] for [[Creator/AllisonPregler Lupa]] reaches this.
--> [[http://thatguywiththeglasses.com/videolinks/teamt/nash/wtfiwwy/32368-this-is-all-your-fault-electric-boogaloo I've had my car stereo]] rigged to play "Making Love" out of nothing at all. I've received more drunk dialing more than anyone who ever dated Creator/CharlieSheen. And I've had live bunnies airdropped into my house.
** In return, WebVideo/TheNostalgiaChick keeps going further into insanity (and she wasn't exactly all there anyway) for Todd. On Website/{{Facebook}}, she's even willing to have sex with his corpse.
* [[https://www.youtube.com/watch?v=lwnFE_NpMsE Juliet's Sassy Gay Friend]] has to agree when she claims this trope by name.

** Crazy Lysa Arryn is largely motivated by her love for Littlefinger, [[MagnificentBastard who uses this to his advantage]]. And as implied by his actions, ie: [[spoiler: kicking off a continent-wide war]] Littlefinger himself has been left [[{{Yandere}} mentally unstable]] by his [[AllLoveIsUnrequited unrequited love]] for Lysa's sister, Catelyn Stark.
