I remember reading a fanfic at the beginning of last year.
It wad after CivilWar and Tony had formed new team,I think with Doctor Strang (???) Don't remember exactly.
The one thing I know 100% ist that Clint was brought back by T'Challa because Laura wanted to see him again. She talked to him and Clint signed the Accords.
Later the Ex-Avengers came back because they were pardoned (also not sure)
It would be awsome if someone find this Fic :)
