We are now boiling down to a wundervision theory that makes us think that the wundervision series is trying to swing us around again.

Yes, after the wrong Pietro (Evan Peters from the Fox film "X-Men," not Aaron Taylor-Johnson from "The Avengers") in episode 5: Yes, we chose Evan Peters from "Avengers: Age of Ultron" instead of Evan Peters of the Fox film X-Men: So, after the wrong Pietro (Evan Peters of the Fox X-Men film, not Aaron Taylor-Johnson of The Avengers/Age of Ultron) appeared in Episode 5, we were in a state of "everything is happening" about the wall collapsing between Fox's X-Men movies and Disney's Avengers movies.

However, during the daytime last week, there was speculation that this might not actually be Wanda's brother Pietro. Here are the most likely candidates for his role.

Paul Bettany said on the "Lights, Camera, Barstool" podcast that there will be a surprise actor in the series, saying, "I'm working with an actor I've always wanted to work with. The scenes are great and I think people are going to be really excited."

This could be Evan Peters, but Bettany reiterates that he "always wanted to work with this guy," suggesting someone older than Peters. Magneto, played by Ian McKellen, may show up to help his daughter.

Much of this speculation stems from a theory posted by redditor TheMediocreCritic. He believes that Loki "may enter Westview and manipulate Wanda to provide what she wants, a mind stone from a different timeline. With the new mind stone, she can resurrect her visions. In return, Loki demands that she release the visions.

But why does Loki take on this pietro form? Recall that Loki is dimension-hopping and has not actually encountered the real Pietro in "Age of Ultron" because the characters have not crossed over.

And do you know who Bethany and Vision have never encountered in a Marvel movie? It's Loki, played by Tom Hiddleston. Loki makes a lot of sense as someone to pull the wool over Wanda's eyes, since he is always changing his appearance to suit his own purposes.

Besides, the Loki series will air on Disney Plus in May, which would be the perfect time to reintroduce him to the MCU.

This theory is more about the upcoming film "Doctor Strange: The Multiverse of Madness." (The demonic and deceitful Mephisto (he is not the devil himself, but he is quite evil) may have a role in that film, if not the main villain). He could easily play the role of the "fake Pietro."

Mephisto also fits the above theory, as there were rumors last summer that Bruce Campbell might appear in the film. Campbell himself even gave reason to believe that he might appear. The theory emerges more clearly when one considers Campbell's history of dealing with darkness and demons in his "Evil Dead" films.

Then again, Campbell and Bettany apparently never worked together.

Mysterio, the villain in Spider-Man: Far From Home, might work because Jake Gyllenhaal fits the above qualifications (he has never worked with Bettany and has the talent to be a chameleon). However, that character seems to have been killed off in the Spider-Man movie, so it is unlikely.

Nevertheless, it is not certain where Wander Vision fits into the overall timeline of the MCU. It may have taken place before Peter and his friends went on their school trip to Europe.
