Ok so I’m 4 drinks in so excuse typos but here’s my new theory is that the events of last week will affect Wanda but also vision. He’ll acknowledge that he’s as much a prisoner as anyone else there because if he leaves, he dies. He tells Wanda as much and basically says he’d rather die then let all those people stay under her thrall. Wanda, knowing she can’t let him die but that she’s gone too far, decides to expand the bubble across the world (and I assume she’ll do it “with the help of family” as the twins and pietro and vision and her all hold hands). Now vision gets to go anywhere he pleases but also isn’t dead.

Also her bubble “activates” all the dormant mutant genes in the world, making mutants.
