It's been a good month or so for Paul Bettany because the actor not only had a starring role in Avengers: Infinity War as The Vision but also showed up as the main villain in Solo: A Star Wars Story. Based on what happened in the former, it appears as if the android's story arc has reached its end and while it's possible that the character could return in a different form, that's not clear right now.
After all, he died twice first at the hands of the Scarlet Witch and then again when Thanos used the Time Stone to bring him back and tore the Mind Stone from his head, leaving him a greyed out shell.
Asked during a recent interview which of his deaths was his favourite, he replied: "Ooooh, I don’t know. I think that being murdered by the love of your life [Scarlet Witch] because you’re asking them to is pretty moving stuff that they wrote for us." He's clearly happy with how things ended for The Vision then but there's a theory going around that he could actually return during Avengers 4.
That points to the android coming back as a greyed out version of himself with no emotions, similar to what happened in a West Coast Avengers story arc many years ago. What do you think could happen?
