So I  highly doubt that all those characters really died at the end of Infinity War

Mostly because Black Panther did so well as a stand-alone movie with T’Challa as the main dude, that to try and have someone else be Black Panther after IW would be fucking stupid story-wise

Now I think the next big Avengers movie is supposed to be IW part 2 – so I’m betting 10$ that those guys aren’t actually dead but instead got transported to an alternate/parallel reality or some shit
