History Heartwarming / ThorTheDarkWorld

* Frigga's relationship with Jane and protecting her from Malekith [[spoiler:to the point of sacrificing her own life]]. It's been established that Jane's relationship with Thor is futile due to her much shorter lifespan, but Thor's mother will defend her because she is the woman her son loves. Doubles as a TearJerker.

* The very fact that Loki still cares about Frigga, and was very willing to join Thor in [[spoiler:avenging her.]]

* Loki's illusion are pretty much flawless, so that isn't how Thor knows that Loki is an illusion when he visits him in prison. No, the reason is something else: [[spoiler:Thor just knows his brother ''so well'' that he knows Loki is lying when he pretends to be fine after their mother's death.]]

* During the battle against Malekith, Loki sees Kurse throw a Black Hole grenade at them. His first reaction is to push Jane aside even if it means he'll die. Heartwarming in that he had no gain in saving her; it was an instinctive reaction. He also sheltered her when the Aether appeared to explode. There are many possible interpretations of this, three of which are: he was saving the girl his brother loves, meaning he still cares for Thor despite his claims otherwise; he genuinely somewhat likes Jane, like he had said earlier; or (most probably), his mother [[spoiler:had sacrificed herself to save Jane, and out of love for his mother, he would not let her sacrifice be in vain]].

** There's also (possibly) the dialogue as [[spoiler:Loki 'dies.']] Made heartwarming as he has no reason to lie at this point, though it's Loki, so you can never really tell.
--->'''Thor:''' I will tell father [[spoiler:[[HeroicSacrifice what you did here today]].]]\\
'''Loki:''' [[spoiler:...I didn't do it for him.]]
** Thor calling [[spoiler:Loki a [[AngerBornOfWorry fool]] for not "listening". Maybe he wanted Loki to focus solely on protecting Jane, maybe Thor wanted to [[LeaveHimToMe kill Kurse himself]], but maybe he also told Loki to stay away because he wanted to make sure that Loki was safe from Kurse too.]]

* At the end, when [[spoiler:Loki is impersonating Odin on the throne, he genuinely, if he wanted, had the chance to turn the tables on Thor, and throw him in the dungeons for committing treason, and none would have questioned "Odin" on it. What does he do instead? He tells Thor he's proud of him, and lets him go. Sure, he's not really Odin, but despite finally being on top he chose not to completely screw his brother over when he had the chance, and even make him feel like he has the fatherly affection Loki never had.]]
** Also, Thor keeps his promise to Loki by [[spoiler:telling their "father" that Loki died in valiant combat like any honorable Asgardian.]]
** [[spoiler:Thor unknowingly telling Loki that he would have been a better king and praising him in front of (who he thinks is) their father. That might have helped in Loki's decision to let Thor go and even praise him as he's leaving. And even though he says "Thank ''you''" in a menacing tone, he could have partially meant "Thank you for finally acknowledging that I am worthy of something."]]
** Even if you take the most cynical approach (which [[spoiler:Loki being Loki]] you probably should) and suppose that [[spoiler:a happy Thor is a harmless Thor, while a Thor-declared-traitor might be more trouble than he's worth... he was offered Mjolnir, peacefully, as a gesture of goodwill. Though he had nothing to lose or gain, he chose not to accept it.]]

* TheStinger is very heartwarming and funny. At the beginning of it, [[spoiler:Darcy and Erik try to comfort Jane because Thor didn't come back. Then there's a storm and he arrives on the backporch. Cue kiss]].
