Vision is definitely real, but he’s nonetheless a creation of Wanda’s – her powers warp reality. I’ve a feeling the series might end with her having to come to terms with his loss though. But then that begs the question, how will their kids remain alive to feature in the no-doubt-forthcoming Young Avengers?
I don’t think Wanda is likely behind this. When would she have become such an expert on American sitcoms? Was there anything in the movies that indicated she watched all these when she was in Strucker’s labs? Also, naturally, people are observing from the outside and trying to break in to her. Her powers may be doing it, but I read all this to mean there is someone else behind it.
Existential questions are interesting here. If this is some sort of simulation or pocket reality, then what is the nature of the reality? If the format of the reality is a sitcom, then only what is on screen actually exists at any moment. So, when Vision is at work on screen, where was Wanda? When Wanda is at the pool party on screen, where is Vision? What do either of them experience “off camera”?
It’s not a question in regular stories or sitcoms because the audience can simply ignore it – they are doing “something” when you don’t see them – but since we know this must be a mediated or moderated alternate reality or simulation, then the perceptions of the prisoners of that reality must be controlled at all times. So, like in Inception, people will find themselves in places and scenes playing the role, but if they are given a second to think, they won’t know how they got there or why they are wearing the same clothes they had on yesterday or why it is suddenly lunch time and they can still taste the scrambled eggs from breakfast in their mouths.
Another interesting point, when the Harts visit, they ask the usual questions of “how did you meet? How long have you been married? Where did you live before moving here?” Of course, Wanda and Vision don’t know the answers.
My question is why would they ask that? It’s not part of the sitcom narrative that they do not know their backstories. If there was a scene in Bewitched, for example, where someone asked where she went to college, the joke would not be that she doesn’t know, but that she really went to Madame Bathory’s Academy of Demonology, but needed to come up with some suitable answer, like Radcliffe, to hide that she’s a witch, and then it turns out that the person’s sister also went there so she has to keep making things up to cover her lie.
So, it is odd that these characters would have lines that inherently call into question the simulation’s narrative.
