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

In WandaVision's fourth episode, the Marvel Cinematic Universe show reveals more about what's going on at Westview, the sitcom reality in which Wanda Maximoff is living with Vision. As the FBI and S.W.O.R.D. investigate what's going on from outside the alternate reality bubble, Monica Rambeau confirms this town is indeed a fake world Wanda is creating to deal with her past trauma. And to illustrate that's just what's going on, Wanda has a brief flashback to Avengers: Infinity War's most tragic -- and futile -- moment.

After realizing Monica/Geraldine isn't her friend, Wanda violently expels the S.W.O.R.D. agent back into the real world. Right after this happens, Wanda repairs the damage she's done to the neighborhood in the process. Vision then enters their home and greets Wanda. However, as he steps into sight, she's shocked at his appearance. In this instance, Vision is the gray, damaged husk that he was at the end of Infinity War when he died. Wanda quickly resets him back to his usual red-and-green appearance, but this underscores Monica telling the authorities that this alternate reality is indeed Scarlet Witch's creation.

Vision's death in Infinity War is one of the MCU's most tragic events. In that film, Wanda first blasted the Mind Stone from his head so Thanos couldn't get it, killing the android in the process. However, this death proved irrelevant, as Thanos then used the Time Stone to bring Vision back and pluck the restored gem from his forehead. This event was the perfect dark, exclamation mark on the Mad Titan getting all the Infinity Stones at last, and as Wanda stared at the bot's empty shell, it was obvious neither her heroism nor Vision's attempt at a sacrifice mattered.

Seeing a re-creation of one of the most traumatic events in her life -- especially after Monica has just mentioned the death of Pietro Maximoff/Quicksilver, Wanda's brother, at the hands of Ultron -- is sure to have a major effect on Scarlet Witch. This whole sequence of events also goes to show just how fragile Wanda's emotional state is right now, and that could lead to bad things when it comes to someone with her powers.

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+.
