TL;DR – We get to see that there more going on than we first though as many questions are raised but answers as still coming.

WandaVision Review –
Well, WandaVision is one of those shows that just when you think you have a handle on what is going on, it pulls the rug out for underneath you. We saw that first at the end of Now in Color and also at the end of last week’s On a Very Special Episode…. All of this means that when you start up the episode for the first time, you have no idea where this show will go.
So to set the scene, at the end of last week Vision (Paul Bettany) had started to take note that something is wrong in this world. He cannot remember what happened of his life before he arrived in Westview, which is not good news for Wanda (Elizabeth Olsen) who is trying to keep the façade of this perfect sitcom world going. But as forces move from the outside, the question has to be asked – ‘Is Wanda in complete control of this universe?’ because while she can come and go, there are growing factors outside of her control. Now from here, we will be looking at the episode as a whole, so there will be some MAJOR [SPOILERS] ahead.
