I can't remember if there were pairings for the second fic or not. For the part I remember, Clint was living in a conference room at SHIELD because he couldn't get back into the barracks until he was cleared as not being a danger anymore. I think he had made a blanket nest on a table and was eating Cheetos or something when Tony found him and brought him back to the tower. I believe this was the start of one of those "the Avengers all come to live together at the tower" fics. Found. Link in comments.
And finally any other fics with Tony & Clint friendship, specifically Clint being kind of a mess after Loki and Tony helping him out.
