There’s a chance that the events in WandaVision are just playing out in Wanda’s head and in a different reality altogether.
In the comics, Wanda is actually one of the most powerful mutants in existence, having the ability to warp reality.
Some believe that the show may be an alternate reality inside Wanda Maximoff’s head, and that she might be going insane following the events of Avengers: Endgame.
Well, that’s when we get into speculation territory.
