After seeing how much Loki's grown in his series, I really hope we see him return to the movie series. He doesn't have to be the main focus for a whole film, but a few scenes where he's important would be good.
Maybe, there can be a movie where Loki and Thor reunite. From what I remember, the original Loki (the one killed by Thanos) and Thor didn't outright say they loved each other. Of course, you can still express love without saying it but, after seeing them fight for years and resolving it right before Loki's death, seeing them say that they love each other.
I imagine that they see each other, and freeze (Thor because of shock and Loki feeling nervous about what to say), but Thor immediately snaps out of it, runs towards Loki, and bear hugs him. Though shocked, Loki hugs him back, and the brothers start crying. Loki starts apologizing for all the pain he’s caused Thor, to which the latter responds, “I’ve already forgiven you, brother. I missed you so much.” Loki smiles and says, “I missed you too brother.”
Later on, when he has to return to the TVA, Loki and Thor say their goodbyes. Thor tells him that he’s proud of how much he’s changed and is happy he has friends there for him. In turn, Loki tells Thor that he’s proud of him too and jokes about how they are no longer the arrogant fools they used to be. They wish each other happy lives and say, “I love you.” Then it flashes back to them playing as children and being happy.
I think this would be a very sweet way for Thor to move on from the pain of losing Loki. I wish it was acknowledged more in Endgame and Love & Thunder, but his depression was mostly played for laughs instead of developed into a full character arc. It also gives Loki the chance to apologize for some of his mistakes and have a nice reunion with Thor, unlike in his timeline where he was still a villain and Thor disliked him.
Bucky and Steve both know a lot about stylizing and brushing hair - Bucky ‘cause when his three little sisters needed help with hair, he was always the only one who had time to helpto them, and Steve because his hair was, before war, long and blonde cute waves. Anyway, they both know a lot about hairtyles and this stuff.
Who is, opposite of them, absolutely helpless with hair is Natasha. Her childhood was red room, she must learn somany things, like fighting styles, languages, shooting, hacking, psychology, etc etc... and she just never had time to just sit down and learn all these complicated hairstyles or anything else.
So, at any time when she needs help with her hair, she goes to Steve and Bucky. They both are her friends and are always absolutely prepared to help her. So, it will usually ended up as Natsha Romanoff, the deadliest Avengers ever, sitting on couch with JAmes Buchanan Barnes, the howling commando, the fist of HYDRA, deadliest assasin in USA history, brushing her hair and Steve Rogers, Captain America, America’s golden boy, the leader of the Avengers, putting sparkling rubber bands in them.
