well to pull from Reddit again they are saying everything after Sylvia tried to mind control Loki is actually Loki using her power against her and he’s projecting the apocalypse in her mind to make her think all is lost so she tells more about herself and what her plans were. As proof They pointed out Loki stopping the building from falling on them when he hasnt really been that powerful so far in the movies and series. I think it might be a little far fetched but don’t really see any other way they manage to get out of there that isn’t Mobious showing up an rescuing them or something lame like that.
Anyway. I’m looking forward to next week to find out!
