When Monica, as Geraldine, mentioned Ultron in episode 3, Wanda became furious and expelled her from her bubble. In episode 4, we get an extended look at that violent exchange, as Wanda demands to know who Monica really is. While Monica claims that she is simply Wanda’s “neighbor,” Wanda knows better. “How could you know about Ultron?” she demands. “You’re not my neighbor, and you’re definitely not my friend. You are a stranger and an outsider. Right now you are trespassing here, and I want you to leave.”
Though Wanda uses her powers to repair the damage she has done to her home and the fence beyond it, something is clearly broken inside her by this terrible reminder of her brother Pietro’s (Aaron Taylor-Johnson) killer. When Vision returns home and asks where Geraldine has gone, Wanda lies to him but can’t hide a certain truth from herself. She turns around and sees Vision’s face as it really is — desiccated and deprived of the Mind Stone, thanks to what Thanos did to him in Avengers: Infinity War. Wanda looks away from his horrifying visage long enough for him to return to his vibrant android look, and she embraces her illusion, declaring, “This is our home … I have everything under control.”
Upon returning to the other side of Wanda’s forcefield, Monica informs her S.W.O.R.D. colleagues that Wanda is indeed in control of it all, saying, “it’s Wanda … it’s all Wanda.” As Wanda then invites Vision to settle down with their twins for their nightly programs, it’s clear she’s using her little TV land to pretend Vision is not dead, even though she knows the truth.
