Awww. So, what does this clip mean? Like, presumably if Thanos’ click was to be, uh, un-clicked, returning everyone who was erased by it to existence, people/androids who died before it would still be dead.

So, the following possibilities are all that could be going on. It has to be one of these:

a) somehow, not only are the finger-click deaths reversed, the deaths that pre-dated it (to a degree) are as well

b) everyone who died by click remains dead, and the remaining Avengers just patch up the big-ass hole in Vision’s robo-skull, and he’s bored because his girlfriend remains dead

c) this is just a cute gag on the internet and not anything to do with the film

(The answer is of course c: that clip comes from the end of Captain America: Civil War, and as such tells us NOTHING other than Marvel know people are getting jittery waiting.)

(But then, why use the Vision, specifically? There’s loads of clips of loads of characters they could have used that wouldn’t lead to anyone suspecting anything re: resurrections. He’s like the thirteenth-biggest character. It could well be that they know something we don’t - Bettany is certainly listed on Wikipedia, although not IMDb, as being in the film, so dependng on which one end up being correct, some sort of mortality-based jiggery-pokery might well be taking place…)
