Didn't Bettany worked with McKellan on a movie before? if not Magneto then maybe it's Stewart's Charles?

Seems Bettany hasn't work with him, Bettany is a huge fan of Star Trek, and in the House of M comic Charles does show up to try to get Wanda to fix the reality.

Of course it still could be Magneto but played by a new actor.

Oh, here's the thing I mentioned before, and I can't help but think of Magneto when looking at this.

Also after the reveal of the one who's been pulling the evil strings, maybe they got Magneto trapped, or something which could possibly explain why this maybe looks like Magneto.

Agnes who revealed herself as Agatha Harkness to Wanda, but while the who was revealed, the why wasn't revealed.

You know I think it would be kinda hilarious if they reveal MCU Agatha Harkness is a witch because she's secretly a Mutant, and then she reveals to Wanda she's a witch because she's a Mutant too.

After all even though people think the show isn't going the Mutant route with Wanda, Disney did change it where Hydra chose her for the experiment because she had the right genetic markers for it, and Feige did teased instead of giving her powers, did the stone unlocked it?

Also so far they still haven't shown the scene where it maybe showing when they did the experiment on her, like it shows her standing in front of the stone, it's glowing blue, then it turns yellow/gold, and well blue and yellow/gold are the colors of the X-Men no?

Agatha would be a Mutant, and there was also a rumor that Wanda would find out she's a Mutant, and what happened to Magneto from Agatha.

Making MCU Agatha, and Wanda Mutants could be a way for Disney/Marvel to get away with using horror stuff without it actually being full on horror witchcraft stuff, especially since it seems China is highly against horror stuff like that, and we know Disney isn't gonna do anything that would upset China.

It's the main reason why I still doubt Disney will let Marvel use Mephisto, or any character like him for WandaVision, Doctor Strange 2, etc. etc.

Wanda's OP powers, Agatha's seemingly OP powers, and Wanda/Vision's kids powers, having them as Mutants would make them/Mutants unique, and change the status quo forever in the MCU.

Like instead of having it where they got their powers from an experiment, or was taught to use magic like Doctor Strange, they can have it where they was born with it thru the lament X-gene, and after they came in contact with the Gems/Stones it unlock their powers.

Also with the mention of the Nexus which seems to have something do with the Multiverse in the comics, if Agatha and Wanda can have access to the Multiverse then making them Mutants would make Mutants even more unique in the MCU.

Another thing it seems MCU Agatha already different with her seemingly being Wanda's villain than mentor.

Also right before she revealed her true ID to Wanda, she told her you didn't think you was the only magical girl in town did you? Then after she revealed her ID to her she told her nice to finally meet you, then she used her magic on Wanda, and showed her it was her pulling all the evil strings all along.

Now there's two episodes left to reveal why Agatha is doing all this, and I just think maybe it'll have something to do with Magneto, Mutants, etc. etc. for Disney/Marvel to use as a last minute twist so they can say surprise! Bet ya didn't see that coming did ya fans?

Luke Skywalker level cameo as the top secret cameo is.

I also don't know if top secret works with him because they confirmed the new F4 movie with a director, so it's expected we'll see the F4 sooner or later.

Now, what wasn't confirmed when Marvel had their announcements at Disney's event? X-Men, and it's possible they didn't announce X-Men stuff because maybe they want to surprise fans with the confirmed arrival of the X-Men/Mutants.

Like maybe the end of WandaVision reveals the existence of Mutants, Wanda's revealed as one/Magneto's Daughter, and to top it all off she and the audience finds all this out from MCU Magneto himself.

I mean it could be possible the actor who Bettany always wanted to work with could be playing MCU Magneto.
