I’d hate for Wanda to end the series alone as much as the next person, but I’m also a stickler for stories sticking to their established lore. If Vision is resurrected completely,
WandaVision better have a decent explanation as to how it won’t mess up the established timeline. Not to mention, it would undercut the series main message about grief.
Will Billy And Tommy Get To Stay?
There are so many questions surrounding how Billy and Tommy even exist, let alone if they will be able to maintain this existence. It was established in the Halloween episode that Vision can’t leave the Hex because, as we now know, Wanda created him inside it. By that same logic, and I really hate to say this, Tommy and Billy probably can’t survive outside the Hex either. This is probably why Wanda consistently warned them to not go past Ellis Avenue, which marked the boundary.
