Since Vision and Wanda were lovers before the Snap, it would make sense for Wanda to be aware of his living will, so part of her reasoning for taking his body from S.W.O.R.D. If anything, Vision would likely leave his body with Tony Stark, who has similar anti-weaponry ideals and would have the resources to make sure that Vision's body is buried in a place that nobody with ill intentions could ever find. Not to mention that we learn about the will from Hayward (who seems dead set on painting Wanda as villain and would have no reason not to leave out any inconvenient truths that could jeopardize his plans) telling Monica about it. It doesn't make sense that his body ends up with S.W.O.R.D., which is an organization he'd reasonably know nothing or next to nothing about.
It also makes sense that he'd want to stay dead—in Avengers Ageof Ultron one of the differences between Vision and Ultron is that Vision isn't really concerned with the ide of living forever. Vision's living will has more stipulations to it than we were told, which is part of why Wanda stole his body.It does make sense that Vision would want to keep his body from being used as a weapon in the event that he dies given his pacifistic nature. What are the chances this is going to bite Hayward in the ass? The revelation of our Vision being a construct and White Vision having been created from his actual remains may play into this.and he's unlikely to be some part of her subconscious manifesting itself either, as it's implied that she's fully aware of what's going on while he's very much not. All in all, he seems to behave a lot more like the people trapped in Westview, like Geraldine/Monica, than he presumably would if he were simply a figment of Wanda's imagination. This explains his acting and thinking seemingly independently (and, more tellingly, outright questioning things) without her presence or awareness, being rewound the one time she does notice. Infinity War makes a point to mention how the Mind Stone isn't the sole component of Vision's consciousness and could theoretically be removed safely, and while this obviously didn't happen, some part of his AI did indeed survive and remains aware enough to break through Wanda's puppeteering.Vision hasn't been revived, but nor was he entirely dead to begin with. SWORD!Vision is driven only by his programming (to kill Hex!Vision) until Hex!Vision presents him the Theseus' Ship Paradox, and which point SWORD!Vision allows Hex!Vision to restore his memories. SWORD still have the original body, and reactivate it using the power Wanda threw at the drone, where it is, indeed, colourless. Hex!Vision has been the right colours all along as he's a wholecloth recreation by Wanda. He still retains his regular colors when he talks to Agnes in episode 6. The footage shown in the trailer with him in his original form, talking to Agnes was color-corrected so as to not spoil anything. When he is inevitably brought back, he will still be colorless and will have no memory of Wanda. When he died in Infinity War, we saw him turn gray and lose his color.
Vision will be colorless and an amnesiac when he returnsIn the comics, Vision died and returned as an all-white version of himself without memories. If he is rebooted, then he's underground, off-world, or otherwise believed by the general public to be dead. Vision is listed among the fallen heroes in the school news show. Spider-Man: Far From Home takes places about eight months afterwards. By all accounts, WandaVision takes place shortly after Endgame.
Maybe S.W.O.R.D got a hold of it, and eventually find a way to bring him back to life. The real Vision will return by the end.We never found out what happened to his body, but I doubt it was left lying around in the Wakanda jungle for five years.
