Episode 4, “We Interrupt This Program,” is an appropriate title because it is in fact an interruption to what has been going on, rewinding to the start of WandaVision and re-telling the story from another perspective, from the outside looking in. We have known since the last scene of Episode 1 that S.W.O.R.D. has been monitoring what we have been viewing as vintage sitcom episodes starring Wanda Maximoff and a somehow-back-from-the-dead Vision.
The episode opens in a hospital, as people are appearing from thin air, the results of the “Un-Snap” in Avengers: Endgame, restoring the lives taken by Thanos’ Avengers: Infinity War Snap five years (their time) earlier.
Other than being pretty much glossed over in Spider-Man: Homecoming, this is the first time we are seeing how people deal with the harsh reality that they’ve been gone for five years, because of what the rest of the world has been calling the “Blip.”
One of those people is Monica Rambeau, the daughter of Carol “Captain Marvel” Danvers’ Air Force pal, Maria. Monica was an agent of S.W.O.R.D. (a Space Force version of S.H.I.E.L.D.) when she disappeared five years ago. Now she is back at HQ, demoted from space duties, and being given the assignment of checking out a Missing Persons case in a town that "doesn't exist."
That town turns out to be Westview, the town in the sitcoms we have been watching. The town is surrounded by an impenetrable forcefield bubble, which unexpectedly allows/sucks Monica inside. Why her and no one else?
S.W.O.R.D. quickly assembles science experts from around the world to figure out what is going on in this town that no locals have ever heard of, and doesn’t exist on any map. One of these scientists is Darcy Lewis (Kat Dennings’ comic relief character from the Thor movies), now one of the world’s leading astrophysicists. Her analysis of the signals emanating from Westview lead her to suspect old analog tv sets might serve as monitors to what is going on inside the bubble, and help them find Agent Rambeau. Dr. Lewis is correct, and the rest of the episode is a recounting of the first three episodes, with agents attempting various ways to penetrate the bubble, and communicate with Wanda. We get explanations and clarification of many of the weird and mysterious things we and Wanda have seen and heard over the last three eps.
There are still many mysteries to be revealed over the next episodes. Why has Wanda created this perfect little world? How and why were the Westview people "chosen" to be there? How do they all seem to know they are not in the real world, but merely playing roles? Do any of these people have dark motives, like Agnes, who seemed very anxious for Wanda to have children? How did Wanda get pregnant, have an accelerated pregnancy, and give birth to twin boys, when that is a biological impossibility with a synthetic husband, even if the Vision is somehow alive and even real himself?
