The Serpent of Doom
- Thor keeps trying to sacrifice himself to save earth and his friends because he thinks it's the only way, Tony however continually disagrees.

- Doom finally relenting when he sees the damage that he's done to his own kingdom.
- OK, so Loki does end up betraying Thor in the end, but just look at the expression on his face when Thor saves him from the serpent.
- And then he saves Thor moments later. Heartwarming when you consider that he was planning on Thor being killed.
- Thor declaring himself and Loki as 'the sons of Asgard', affirming that he'll always see Loki as his brother. Although Loki corrects him snidely with 'adopted brother', he does pause and look surprised at the sentiment.
- Even when Loki turns against him. Thor insists that he will save his brother, even if it's from himself. It's nice how their brotherly relationship seems to take a lot from the movies.
- Loki screams for Thor to help him as he's floating in space in the Destroyer suit and Thor does, when he could've easily left him to rot on the throne.
Hulked Out Heroes

- Even better, when Fury calls up to ask about her progress on developing a contingency plan in case The Hulk goes out of control, she basically tells off Fury on Hulk's behalf.

- After Thor returns to Avengers Tower after destroying Doom's time machine to prevent him from taking over the world, all the other Avengers are fighting over minor things like training, ice cream makers, and Hulk's glass figures. Thor just laughs, glad to have everything back to normal.Hulk: Think this is funny Goldilocks? Go back to Asgard!
- When Odin starts to get a little to mouthy demanding that Thor ceases his "fun" on Midgard and return to Asgard. Hulk takes preemptive action, by sending Odin into the nearest wall, hard. Instead of angering him, Odin is impressed with Hulk and instantly decides to be his friend.
- Thor is very protective of Odin throughout the episode.

- What was Tony's Halloween costume when he was eight? None other that Captain America.
The Dark Avengers

As Tony himself put it:Villain!Tony: We're all on the "most wanted" list but have any of us actually taken a life? (everyone else goes silent) I'm guessing we're not very good at being badguys.
- Cap fails to do anything villainous throughout the episode. Even protecting Falcon simply out of habit.
Back to the Learning Hall
- Watching Thor enjoy playing fetch with his pet Bilgesnipe, surprisingly adorable.
- Falcon telling Thor that he isn't useless.
- Despite the infinity stones constantly trying to corrupt her, Natasha lasts longer than anyone else (save Doctor Strange) against their influence.

- Tony apologizing to Hulk for blaming him for the havoc Speed Demon caused throughout Avengers Tower.
- From the start Ant-Man argues that Doctor Spectrum, who was one of the people he'd sold his technology to really isn't all that bad.

- At the beginning of the episode, Steve has two pictures. One is of him and Bucky. The other is of a woman, who we can all assume is none other than Peggy Carter, his first love. Pretty Heartwarming in Hindsight, considering that in the MCU, both of them keep pictures of the other to remember them by, showing how strong their love was.
- At the end of the episode, Cap has one more picture next to his bed of the other Avengers. It's pretty apparent that Steve thinks of the Avengers as his only friends in the modern era, if not his family.
- Most of the Thunderbolts aside from Zemo reforming is pretty heartwarming on it's own. But the real stand out among them is Beetle, it's outright shocking considering his previous characterization in Ultimate Spider-Man that he figured out Good Feels Good.
Into the Dark Dimension
- Even though the Avengers were concerned over the Thunderbolts stealing their (ahem) thunder, it appears the most common Halloween costumes are still The Avengers.
- A subtle one, but still. Captain Marvel (Carol Danvers) apparently is an active hero, with quite a few kids dressing up as her.

- Apparently Tony had made upgrades for his friends. This is sweet on it's own, but there's no indication that he would have known he'd find them in the pyramid, or on Battleworld period, so he was just carrying around upgrades for them while lost in a desert.
- All the Avengers are so happy to have Tony back.
- A small moment at the beginning: when all the Avengers are trying to attack him, Loki hides behind Thor. He still has faith that Thor will care enough to protect him, and while Thor isn't happy to see his brother, he's notably the only one who doesn't try to attack him.
- The talk Tony has with Thor about Loki is so sweet:Thor: Loki. I've always tried to help him, in case he ever truly had a change of heart. I've long given up hope that Loki will ever change.Tony: You can't fix other people. When someone like your brother is flailing, it's not your job to rescue them from themselves. It's your job to be there for them when they're ready to get their life together.
- Especially touching given Tony's struggle with alcoholism is a big part of his character in the comics and other media.
- This line from Tony:"When I was lost in another dimension, I never lost hope in the people I care about. Don't you lose hope, Thor. Sometimes hope is all we've got."

- Loki actually manages to pull a HeelFace Turn over the course of the episode. He starts off by simply wanting to go against the Beyonder because the latter double-crossed him and took apart Asgard, but throughout the episode Loki gets more and more heroic.
Loki: I'm an Avenger now- (gets interrupted by Enchantress blasting him back)
- Despite questioning the concept of saving people, Loki learns quickly and proceeds to block off the trolls' access to New York so they can't come back. Thor even compliments him on it.
- And even though they've been arguing with each other up until now, Loki purposely makes Hulk angry in order to help him out of the cave-in (since his anger makes him stronger).
- The moment towards the end where Loki doesn't double-cross them.
Loki: I can save Asgard and Earth!
- At first Loki is only concerned about saving Asgard. But when he's trying to activate the Bifrost, what does he tell Thor?
Beyonder: They're not my planets, they're not my people.Loki: No. They are ours.
- And to top it all off, he begins the episode repeatedly saying "MY Asgard". But at the end, when he faces the Beyonder with the other Avengers, who asks why he should care about the lives of others:
