First episode, I thought it was pretty obvious that Wanda and Vision (or maybe just one of them) are in like a virtual reality thing. First episode made it seem like they were trying to get Vision to do something for them or give them some sort of information. I thought the calculation thing was the point.
Basically, like the Matrix, or that episode of Rick and Morty where those aliens try to get Rick to teach them how to make dark matter (or whatever it was).
Second episode made me doubt that just slightly, as Wanda being able to rewind wouldn't make sense.
