More info:

Everyone has their own floor, unless they are a couple.
Loki isn't bad and the team knows he was brain washed.
Thor and Loki get along.
Steve never leaves for Peggy
Peter is 18 years old.
Sam will become Captain America.
Tony isn't angry at Bucky or Steve.
Endgame will still happen but with a twist.
Loki never dies.

Eva's info I missed:
She is very powerful, she can control time, she has the same powers as Wanda put more powerful and blue but when she uses them too much it drains her and it gets hard for her to use them again.

I think that's it, if I missed anything I'll add it in here.
