The ending of Avengers: Infinity War was groundbreaking in many respects.
(This is something that we have previously scene within Avengers: Infinity War proper.)
So just what does the post-credit scene for Avengers: Infinity War mean?
And if it does go that way, and it can pull what seem like all the disparate parts together, there is a very good chance that when Marvel Studios unleashes The Avengers 4, it will be even more groundbreaking than Avengers: Infinity War.
