I've seen that already and all of the rest of the shows. I am just missing the newest ant-man and the newest Guardian of the Galaxy. Would I miss much?
I haven't seen BP2 yet but didn't feel out of the loop during the Ross scene. But then again there may have been something deeper that I wasn't picking up on.
Not really just that Ross is 'off the grid' and not with SHIELD officially. He was arrested for having direct communication with Wakanda and charged with compromising national security by Valentine deFontaine.
