Elizabeth Olsens Wanda Maximoff has always had among the most tragic tales in the MCU she was orphaned at a young age lost her brother and home became the most feared person in the world and finally lost the love of her life Vision to Thanos. That all led to her tragic arc in Phase 4 that culminated in WandaVision and Doctor Strange in the Multiverse of Madness with her villainous turn and eventual death to destroy the Darkhold.
Despite that Wanda aka Scarlet Witch remains among the most beloved characters in the MCU so fans are certain she will be back and will eventually lead her big-screen blockbuster. Ahead of that the ever popular WandaVision will soon see a spin off with Agatha: Coven of Chaos set to arrive in Winter 2023 starring Kathryn Hahns Agatha Harkness. With the series spinning out the events of WandaVision in which the Salem witch served as an antagonist to Wanda many are convinced that this will be where Olsen makes her MCU comeback. The Direct has one theory that explains why she will be back and how she fits into the puzzle.
Following the climactic battle of WandaVision, only moments after Wanda had transformed into the Scarlet Witch viewers were left with a brief tease that hinted at the reunion between the two. Just before Wanda transformed Agatha back into the nosy neighbor of Westview leaving her memory clear of magical knowhow the dark witch promised she was gonna need. Now what Agatha is referring to is Wanda having unleashed what appears to be the full power of the Scarlet Witch something that was explored in Doctor Strange in the Multiverse of Madness. Assuming Wanda did survive the climax of that blockbuster perhaps she will require expertise to clear her Darkhold corruption as she learns to properly understand her Chaos Magic.
The WandaVision spin off is even sub titled Coven of Chaos while Wanda herself famously uses Chaos Magic Agatha utilizes Dark Magic. As of now the Sokovian native is the only known Chaos Magic user to be introduced in the MCU which already creates a close connection between Wanda and the upcoming series.At the time of their encounter in WandaVision Harkness was attempting to harness Maximoffs Chaos powers for her own use and that may well be her goal once again in Coven of Chaos. Perhaps she will attempt to achieve that through the guise of helping Wanda or maybe she genuinely will have some good intentions this time around.
