In The Avengers: Age of Ultron, we saw the newly introduced character Vision, whose creation partly involved
the Mind Stone Infinity Gem being fused to his forehead. His possession of the Gem is used to explain a number of important aspects of his behavior.
If that gem were removed, would Vision (as he exists at the end of the movie) continue to exist? Is that element required to allow his body to contain his consciousness in the first place?
