WARNING: The following contains spoilers for WandaVision Episode 7, "Breaking the Fourth Wall," now streaming on Disney+.

WandaVision's latest episode, "Breaking the Fourth Wall," ended on a twist not too surprising to comic book fans: Nosy neighbor Agnes is actually the powerful witch Agatha Harkness. But the emergence of "not the only magical girl in this town" does set up some implications for the actual source of Wanda's powers, as well as her role in future Marvel Cinematic Universe films.

In "Breaking the Fourth Wall," Wanda finds Agnes' basement full of overgrown vines and a chamber hosting everything from skeletons to a mysterious golden book. Agnes then drops the facade to reveal her true identity. And as the subsequent theme song tells us, much of WandaVision's strangeness has been "Agatha All Along." The witch has been responsible for everything from the odd behavior of their neighbors to the death of their dog Sparky to even the re-emergence of Pietro, albeit with a different face.

Like Wanda, Agnes has the ability to wield magic, but they appear to come from completely different places. The MCU has the Scarlet Witch achieving her powers via experiments performed on her and her brother by Wolfgang von Strucker. The baron used Loki's scepter containing the Mind Stone, which unlocked a number of latent powers within Wanda, including telekinesis, hypnosis, and energy projection.

In the comics, though, Wanda has a completely different origin story. Initially, it's believed that she and Pietro are the mutant children of X-Men nemesis Magneto. But an issue of Scarlet Witch reveals that she actually came from magical experiments done as a baby by geneticist Herbert Wyndham. The "High Evolutionary" made her a conduit for chaos magic, which gives her the powers to manipulate, warp and reconstruct the essence of reality.

The revelation that another character in the MCU exists with reality-bending powers means that Wanda's abilities may not be completely from the Mind Stone. It's possible that some of the comics lore is now leaking into this adaptation, as Von Strucker's experiments didn't give her powers, but merely unlocked her ability to channel chaos magic. That's why, as Pietro indicated previously, her powers have grown leaps and bounds since the simple hypnosis she employed in Avengers: Age of Ultron. The ability to create and maintain a reality as complicated as the one inside the Westview anomaly can only come from a source as great as chaos magic.

If Wanda is indeed a magic user, that links perfectly with her role in the upcoming Doctor Strange in the Multiverse of Madness. Ever since Marvel Studios announced that WandaVision would tie into the film, fans have been curious as to what that setup will be. Perhaps this reveal is that setup. Up to this point, Doctor Strange was the only part of the MCU to really deal with the occult and the mystic arts. If Wanda is a magic user, rather than someone granted powers through an Infinity Stone, that easily connects her to that world. And considering the breadth of her abilities at this point, she may serve as a key friend -- or foe -- to the Sorcerer Supreme.

Written by Jac Schaeffer and directed by Matt Shakman, WandaVision stars Elizabeth Olsen as Wanda Maximoff/Scarlet Witch, Paul Bettany as Vision, Randall Park as Agent Jimmy Woo, Kat Dennings as Darcy Lewis, Teyonah Parris as Monica Rambeau and Kathryn Hahn as Agnes. New episodes air Fridays on Disney+.
