I still think Wanda pulled Peter through the Nexus and Agatha seized the opportunity to possess him. He's still wearing his colors in the post credits scene. Either Agatha is too busy with Wanda at the moment and he was able to snap out of it (being the only other actual super human individual there besides Monica), or Vision will get to him too. If Disney were to go meta with this it would be a giant lost cause and make no sense to open up to the Multiverse of Madness. I also think if he were bad, we would have seen him knock Monica over the head and then cut the scene.
A few things:
-Agatha's house is literally the Bewitched house.
-Scratchy is an amalgamation of her son from the comics, Nicolas Scratch and her shapeshifting black cat
-One of the circus tents was "Fool the Guesser"...another Fourth Wall break
-The book in the basement appears to be the Darkhold
-The licence plate shown during the
Office-style opening shows the number 122822 – which is S.H.I.E.L.D.’s designation for the planetary event known as “The Pulse” in the video game universe featuring Reed Richards.
I still think the people in the commercials are her parents and that Dottie could be Clea?? There's a theory going around that some of the other women at the 60's pool meeting are also witches, and that Agatha is their coven leader. Clea is a sorceress, so it lines up with meeting Doctor Strange.
The films he played Magneto in were set in the 60s/70s. In Dark Phoenix, which was set in the 90s, he was supposed to be in his mid-60s.
Those were technically set in the 80's, hence the clothing and "Sweet Dreams", as well as Jubilee. Peter was pulled in during the 80's episode...
They can retcon the earlier X-men, saying that they were in the future, to understand the age-up of Prof. X and Magneto.
Paul Bettany just came out again and said he doesn't know why people keep thinking the person he's refering to is Doctor Strange, but that it is an "actor I've wanted to work with my whole life."
...McKellan or Stewart. Doesn't appear that he's worked with either.
PS: Who the hell was talking back to her in the fourth wall scene towards the end?? "You aren't supposed to talk..."
