* Thor and Jane's reunion, after she stops slapping him.
* Meta example: Natalie Portman wanted to return for this movie and signed on, but couldn't work on it at the time due to being on Maternity Leave. What did the production team do? Why, hold off on making the movie until she could participate, of course!
* Another meta example: is [[http://www.youtube.com/watch?v=rfJjB43AE9E director Alan Taylor's apology to James Gunn.]]
* 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.
* Sif and Volstagg being protective of Thor was just precious.
* In the scene where Jane is being examined, Jane and Thor keep exchanging smiles.
** More specifically, when Jane correctly guesses that the tech above her is a quantum generation field, Thor's proud that's-my-girlfriend smile is just ''adorable.''
* When Odin takes Thor and Jane into the library, explaining about the Dark Elves, Thor recalls the story in saying, "Yes, Mother used to tell us stories as children." '''Us''', as in, he and Loki. It's small, but it shows that Thor hasn't forgotten his brother or the times they spent together.
* The very fact that Loki still cares about Frigga, and was very willing to join Thor in [[spoiler: avenging her.]]
** Frigga and Loki's entire relationship - she begs Odin to spare him, and then visits him in his cell against her husband's wishes, bringing him books and trying to make him comfortable. She's the only one in the movie Loki seems to value and doesn't lash out against. It's also very telling that she's the one who taught him magic - young Loki must've felt very insecure under his father and brother's shadows, and Frigga gave him something that was his own.
* When they're in the Dark Realm and Jane is still unconscious, Loki starts to question Thor on him choosing her; he says that she's like a moment in their long lives, and will be gone before Thor knows it. What makes this heartwarming is that Loki appears genuinely concerned about his brother, knowing that Jane will only cause him heartbreak.
** In the same scene, after Thor and Loki have an argument about Frigga, this exchange happens which is both heartwarming and giggle-worthy:
--->'''Thor''': No... (Mother) would not want us to fight.\\
'''Loki''': ...Well, she wouldn't exactly be shocked.
*** Right after that, Thor gives him a small fond smile. And if you look close enough, you would see ''Loki'' giving him an even smaller one.
*** Despite everything, Thor says "I wish I could trust you." And Loki seems affected by it.
* 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 like an instinctive reaction. He also sheltered her when the Aether appeared to explode.
** Then Thor saves Loki. Most importantly of all; in spite of all his claims to have severed kinship with him like Odin has, Thor ''still'' loves Loki dearly in spite of himself.
** Then Loki saves Thor. Watch his expression when he sees Kurse beating up Thor. It's a 'nobody gets to attack my brother except me!' face.
** 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 you [[spoiler:died with honor]].\\
'''Loki''': [[spoiler:...I didn't do it for him.]]
* 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 kept his promise to Loki by [[spoiler:telling his "father" that Loki died in valiant combat like any honorable Asgardian.]]
* 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]].
* In its way, the [[VillainousFriendship relationship]] between [[BigBad Malekith]] and [[TheDragon Algrim]] is pretty sweet and caring. They're clearly fire-forged companions and while Algrim's self-sacrifice is ultimately for a pretty terrible cause, his total trust is pretty touching.
* When celebrating the recent victory, Volstagg is shown surrounded by adoring children and holding a young girl on his lap. The credits list the children & woman as his family, which makes it all the more heartwarming.
* Hogun the (normally) Grim smiling happily when Thor tells him he should stay on Vanaheim for a while with his people.
* Odin being a ShipperOnDeck for Thor/Sif. It seems he approves of ladies being fierce warriors ([[AmazonChaser which makes sense, since Frigga is shown to be pretty badass herself]]).
* Not in the movie, but [[http://marvel.com/news/story/21573/lady_sif_visits_the_childrens_hospital_los_angeles Lady Sif herself visiting a child's hospital]]. Jaimie Alexander is very cool.
* The way Loki still calls Thor "brother" despite claiming that Odin is not his father and being still pretty messed/torn up by TheReveal.
* Sif is strongly implied to be in love with Thor, who loves Jane. However, Sif never lets any jealousy influence her, and during the escape from Asgard, she is the one who gets Jane out of where she's being kept and later escorts her.
* Jane tries to drag an unconscious Thor out of the path of a giant falling spaceship, but he's too heavy to move away in time. At the last minute Jane throws herself on top of Thor: shielding him with her body as much as she can while ensuring that they'll die together.
