It’s a bummer of a way to go, but there is a path that Marvel can (and should) still take with the Vision.
There’s been a lot of debate about how Avengers 4 will handle several key characters disappearing into the wind, but not everyone met their demise by The Snap.
Vision (Paul Bettany) had perhaps the most tragic death of the movie, as he convinced his love Wanda (Elizabeth Olsen) to kill him and save the universe in the process, only for it to mean nothing as Thanos simply reversed time and killed Vision himself.
There are a lot of questions left unanswered after the ending of Avengers: Infinity War, most of which has to do with the fate of the characters who were affected by Thanos’ fatal snap.
