WARNING: The following contains spoilers for WandaVision episode 4, "We Interrupt This Program," now streaming on Disney+.

Few other shows are as perfectly designed to fuel fan speculation as WandaVision. With its eerie aesthetic, shifting aesthetic, and a mind-boggling number of winks and nods connecting it to the rest of the Marvel Cinematic Universe, there is unending fodder for crafting theories. Some mysteries may be hiding in plain sight, however, and it's only once one thinks about them that they become bothersome. Case in point: If everyone in Westview is a real person caught in Wanda's web, then who is playing the role of Vision?

The narrative's shift in "We Interrupt This Program" to the perspective of S.W.O.R.D., the government agency monitoring the events from the first three episodes, came with some startling revelations. But one of the most intriguing unsolved mysteries involves the backgrounds of Westview's residents. Since the altered reality of the sitcom setting already shifted the world to fit its cozy black-and-white image, it doesn't seem to be like a huge leap to assume from the outset that Wanda pulled her supporting cast out of thin air. However, when Monica Rambeau turned out to be an agent of S.W.O.R.D. and many of the others were identified in the latest episode, that assumption fell flat.

With real-life people essentially serving as actors in a sitcom Wanda forces them to be in, shifting their minds to fit their altered perspective, it's only natural to wonder who is playing the part of Vision. Murdered in Infinity War when Thanos crushed took the Mind Stone from his head, it would be a remarkable feat for Wanda to completely reinvent the one of a kind synthezoid when she needed actors to play everybody else. In that sense, Vison must be a real person, and the comics may point to their identity.

While his origins in the comics are drastically different than in the MCU, one notable element in the source material is that the Vision's brain patterns are mapped after the character Simon Williams. Williams, aka Wonder Man, was initially a mole given powers and embedded into the Avengers to betray them, but he later had a crisis of conscience and proved himself a hero. Since he was the template for Vision, there came frequent drama resulting from each man's romantic entanglements with Wanda, and how this fits into WandaVision's setting seems only natural.

It's possible that Williams is the real-life person Wanda is mind-controlling to look and act like Vision, and there's even another mystery he could slip right into in the form of Agent Woo's missing person. When Woo is first brought in on the case, it's to find an unnamed member of the Witness Protection Program who went missing. If that character is Williams, then the show would have good reason to not drop his name given the massive clue it would be to fans of the comics.

Despite the missing person case being his whole reason for investigating, Woo never identified who he was looking for as S.W.O.R.D. monitored the broadcasts of Westview. Throw in the fact that Wonder Man's design was spotted in a WandaVision featurette, and it's almost a sure bet that the character is included somehow. The show may be called WandaVision, but the more it progresses, the more it seems like it'll end up being more "WonderVision."

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. A new episode debuts each Friday on Disney+.
