Doctor Doom digs the Scarlet Witch out of Wundagore, five weeks before Doomsday

The finale, "Forever," is the eighth and last episode of the Disney+ series. It went up on Nov. 10 at 6 p.m. Pacific and has two post-credits scenes. The second one goes back to the closing moments of Multiverse of Madness. Wundagore has collapsed. A hooded figure lifts the rubble off Wanda's body with magic and speaks to her, and she wakes with a gasp.⁠16⁠6⁠1⁠7

Polygon says the figure is Doctor Doom, played by Robert Downey Jr. Tonights.tv is more careful and calls it a hooded figure that appears to be Downey's Doom. Outlets don't even agree on the exact words: IGN quotes the line as "Your power will be mine," singular. The plural and the singular mean the same thing, though, and neither one is a rescue. Doom isn't saving Wanda. He's claiming her. Avengers: Doomsday opens in theaters on Dec. 18, 38 days after the finale, so Marvel has left its biggest open question hanging for just over five weeks.⁠1⁠7⁠4⁠8

The scene works because of how Wanda's last film ended. In Multiverse of Madness she was the main villain. The Darkhold, a cursed book of dark magic, corrupted her as she tried to get back the sons who had seemingly ceased to exist when Westview dissolved. She summoned demons to hunt America Chavez, played by Xochitl Gomez, so she could take Chavez's power to travel between universes. She killed nearly all of the Illuminati, a team of heroes from another universe, among them Charles Xavier, played by Patrick Stewart, and Peggy Carter, played by Hayley Atwell. Then a version of Billy and Tommy from another Earth recoiled from her in terror. She brought the mountain down on herself so that no one could ever use the Darkhold again.⁠1

That sacrifice was the only redemption the character got, and it worked because it was final. VisionQuest has taken back the death. Doom's line suggests the redemption may go too. He doesn't offer the woman he wakes a second chance. He announces that he will take what she has.

Marvel has not formally announced Elizabeth Olsen as part of the Avengers: Doomsday cast, and we found no such announcement. For now the scene itself is the evidence, and the trade and fan press read it as a tease. Variety's headline puts Olsen's Scarlet Witch in Doomsday, and the article says that although the WandaVision saga has ended, the Scarlet Witch's story seemingly continues. The Direct reports appearances by Olsen's Scarlet Witch and Downey's Doom. Deadline says only that "a major player appears to be returning to the MCU," and GamesRadar says Marvel "just resurrected Wanda." Polygon's headline goes furthest, saying the scene "officially confirms" an Avenger's return. Calling a post-credits stinger official confirmation is a stretch, but the stinger is clear about what it means.⁠3⁠8⁠2⁠5⁠1

Critics have not all been impressed. Vulture called the tease "exciting in its revelation and inelegant in its execution." TVLine said it "raises some major questions" about Doomsday. Vulture also places Doomsday "in about a month," with Secret Wars to follow "after a year's intermission."⁠9⁠10

The scene also seems to settle a puzzle Marvel set up months ago. At San Diego Comic-Con, Marvel showed three masked figures in colored cloaks over three days and called them the Latverian Witches, magic users who serve Doom in Doomsday. Those cloaks were green, purple and gold. A poster released in early October showed Doom followed by witches in green, purple and red. Polygon reads the Scarlet Witch as the red witch, which is the obvious reading now.⁠1

Marvel hasn't shown who wears the other two cloaks, so everything beyond red is guesswork, and it should be labeled that way. Polygon's pick for green is Sylvie, the Loki variant played by Sophia Di Martino. Loki, played by Tom Hiddleston, is already confirmed for Doomsday. For purple, Polygon suggests Agatha Harkness, played by Kathryn Hahn, who died at the end of Agatha All Along, or Clea, played by Charlize Theron, who has not been seen since the Multiverse of Madness mid-credits scene.⁠1

The finale's first post-credits scene goes in a different direction. Ultron, played by James Spader, holds a computer chip labeled Jocasta. Polygon explains the setup: the scientists Josephine Carrington and her husband Virgil Horton scanned their own minds to build advanced AI. Virgil was the blueprint for Ultron, and Josephine, played by T'Nia Miller, was the blueprint for Jocasta. After she died of a degenerative hereditary disease, Virgil put her mind into a synthezoid body and erased her memories of him. That synthezoid then fell in love with Ultron. In the finale, Virgil killed Jocasta with an adamantium bullet. In his rage, Ultron nearly wiped out London with nanobots until Vision, played by Paul Bettany, talked him down by trapping him in a sitcom. Ultron shut off the nanobots and fled. The chip suggests he wants her back. Nothing on screen says when, and nothing ties this scene to Doomsday.⁠1⁠17

Polygon also reports that Marvel Studios posted a message in binary code on X, and that it decodes to "We could never leave each other, even if we tried." That echoes Wanda's line in the WandaVision finale: "You know, a family is forever. We could never truly leave each other, even if we tried." The timing matters, because VisionQuest, run by showrunner Terry Matalas, ends with Vision back with Billy and Tommy. Tommy is played by Ruaridh Mollica, and Polygon names Joe Locke as Billy. Polygon reads the post as a sign that Wanda will find her way back to that family. That is a reasonable guess, but Marvel hasn't explained the post.⁠1⁠11⁠15
