With the character development that Wanda had in her solo series, as well as her new official identity of the Scarlet Witch, it feels like there is still a lot left to explore with her character in the MCU timeline. Luckily for fans, Olsen’s return as Scarlet Witch feels inevitable based on recent comments from Kevin Feige and Olsen herself. There is concern that certain storylines would take away from Wanda’s legacy, and undermine the impact of her original death. However, there is one direction Marvel can go in that wouldn’t affect the character’s past.

The X-Men will inevitably make their MCU debut, and Marvel will no doubt make sure it is a grand entrance considering the audience reaction to Deadpool & Wolverine. Having a variant of the Scarlet Witch arrive with the rest of the X-Men would be a way to provide a big twist to the MCU. It would also allow Olsen to return as the character, who would be a different enough version to feel entirely different from her past MCU portrayal.

Wanda’s Death Was Her Personal Atonement

One of the biggest issues with bringing the Scarlet Witch back through reincarnation is that it would undo the impact of her death. In Doctor Strange in the Multiverse of Madness, Wanda recognizes her corruption, acknowledging all of the wrongs she did. To make up for her mistakes, she sacrifices herself to destroy the Darkhold so that no one will ever be corrupted by it again. Her choosing to destroy the cursed book at all costs felt like the ultimate atonement for her actions in Doctor Strange 2.
If Elizabeth Olsen does make her live-action return as Wanda, the X-Men route would be a unique storyline. It would allow Olsen to bring the same nuance to her character that she did before, but with a version that is clearly different. Her Multiverse of Madness death is too impactful of an event to just undo, so introducing her in a new team that she already has canon ties to could be the way for Marvel to go. Scarlet Witch has become such a popular character, and putting her with the highly-anticipated X-Men would give the studio so much potential to work with.
