Chris Evans hints at a “dangerous” Captain America in Avengers: Infinity War.
Cap is probably the most changed Avenger since the last time people saw him in Captain America: Civil War.
Part of that is in his nature, part of that is just to keep his sanity, and that all kind of goes out the window a little bit after (2016’s Captain America: Civil War).
Cap’s new-found spontaneity may have allowed him to try the things he wants to do, but it also has some ramifications on his characterization.
