2. I remember that it was one of those Steve having trouble adjusting fic. He has good days and bad days. I remember after he has a bad day and the Avengers have a bad day, he doesn't want to be around them because he doesn't want to drag them down (he shouts at them, specific Tony, who probably takes it the wrong way/personally). Then he trashes his apartment and Bruce comes by and cleans up the glass and checks up on him. I think it might have been Steve/Tony, but I can't be sure, and if it was it was still pre-relationship/slow build (in the chapters I've read). Fairly certain that it's a wip, and not complete.
3. The scene that stands out to me is: the Avengers (plus Fury), have gathered for a meeting/debrief? and there is some tension/back-and-forth/comments between Steve and Tony which Steve reacts strongly to, stunning everyone when he gets up asks Natasha for the notes (which she silently agrees to do for him) and leaves before the meeting/debrief ends/possibly before it starts. I don't remember if it was shippy or not.
