The “WandaVision” finale sets up the next “Doctor Strange” movie in a big way. The Disney+ show had only one direct reference to the Sorcerer Supreme, but it’s clear that he’s connected to Wanda Maximoff’s future—but she might be the antagonist in “Doctor Strange in the Multiverse of Madness.”

“The Scarlet Witch is not born, she is forged,” Agatha Harkness (Katherine Hahn) explains to Wanda (Elizabeth Olsen). “She has no coven, no need for incantation. Your power exceeds that of the Sorcerer Supreme. It's your destiny to destroy the world.”

That climactic scene sets up quite a bit. Doctor Strange (Benedict Cumberbatch) is apparently not as powerful as Wanda, so it stands to reason that they’re either becoming allies or foes. The fact that the Scarlet Witch is preordained to bring the apocalypse makes it seem like she might even be the villain.

The end credits scene makes it clear that although Wanda let go of her hold on Westview, she hasn’t given up on her family.

Wanda is secluded in a cozy cabin in the mountains. While she enjoys her tea, viewers see that she is astral projecting in her fabulous new Scarlet Witch costume. Scarlet Witch is levitating and reading the Darkhold, a book full of the darkest magic in the universe.

As the camera zooms in on her red eyes, the audience hears the cries of her sons. It seems Wanda is looking for a way to bring her sons back—and that might lead her to the Multiverse of Madness.

“WandaVision” didn’t bring in the multiverse as expected. When Evan Peters showed up as Pietro, it seemed as though Marvel Studios was finally bringing in the X-Men from another universe. However, Peters was revealed to be Ralph, just the aspiring actor who lived next door under Agatha’s mind control.

Though the fake Pietro ordeal didn’t open the door to another universe, it did confirm that other universes can contain doppelgangers. While Spider-Man: Far From Home” confirmed that J. Jonah Jameson (J.K. Simmons) looks the same in both the Tobey Maguire Spider-Verse and the Tom Holland version, “WandaVision” seemingly establishes that this isn’t always the case. Sometimes doppelgangers are completely different people.

Pre-pandemic, “Doctor Strange 2” was supposed to be coming out in May, giving audiences not much time between “WandaVision” and the new movie. The world has changed, though, and now the sequel is set for March 25, 2022.
