Loki seems like he’s coming back, but not present Loki. Loki from Avengers 1 is in the leaked set pics.I really hope they aren’t bringing Loki back, as much as I love the character. We need more permanent deaths, especially in big, universe-changing movies like this.
I’m personally hoping both Iron Man and Captain America get clapped in Avengers 4 to really give the movie some gravity. You can’t just undo half of the universe being erased without some sacrifice.
The best idea I’ve heard about how mutants will be introduced without having to say why they weren’t there before is that the snap introduced the mutant gene to people assuming that they come back.They are already laying the foundations to including Mutants with a slight tweak to Scarlet Witches backstory
