A new behind-the-scenes featurette makes the case that the wild ride we’ve been on in WandaVision hasn’t even kicked into high gear yet. Showrunner Jac Schaeffer and director Matt Shakman’s patient, period-perfect series has begun to reveal some of the secrets it holds. The sitcom world that Wanda (Elizabeth Olsen) and Vision (Paul Bettany) exist in seems to be of Wanda’s creation. As we’ve seen in recent episodes, Monica Rambeau (Teyonah Parris) infiltrated Wanda’s Westview creation to find out just what the heck is going on in there. What we’ve learned thus far is that Wanda built this alternate reality in order to reanimate and live with her lost love Vision. Vision, of course, was brutally killed by Thanos at the end of Avengers: Infinity War, only he wasn’t snapped into dust, he was literally killed. This means that when the Avengers undid Thanos’s snap in Endgame, it couldn’t bring Vision back. Only Wanda could do that.

Recent episodes have pulled back the curtain a bit. We now know that S.W.O.R.D. is onto Wanda’s machinations, with Monica reporting from the inside and Jimmy Woo (Randall Park), Dary Lewis (Kat Dennings), and Director Hayward (Josh Stamberg) trying to crack the case from the outside. The end of the last episode offered the first evidence of those cracks starting to form. First, you’ve got Vision himself starting to realize something is not only wrong but that it’s Wanda’s doing. Second, you’ve got Wanda herself confronting S.W.O.R.D. in the real world, and third, you’ve got tremors within the larger MCU making things confusing for Wanda herself.

That was most evident when her brother Pietro/Quicksilver (played by the X-Men‘s Evan Peters!) shows up at the end of the episode. This was odd not only because it seems to be a bit of an X-Men crossover with Peters playing Pietro and not Aaron Taylor-Johnson, who played him in Avengers: Age of Ultron, but Pietro died in that film.

The featurette promises that Wanda’s world of Westview is about to break down. Paul Bettany himself says, “I think it’s gonna be really satisfying when people realize what is at the heart of this show.” And what will the heart of this series be? It’s anyone’s guess at this point, but you can rest assured it will have major implications for the MCU going forward.

Check out the featurette below. WandaVision‘s next episode streams on Disney+ on Friday.
