There Is A Light (That Never Goes Out) (слэш)

Relationships are more easily broken than Tony used to believe. Rebuilding a family for himself isn’t as easy as he hoped, as Loki and Peter - the two people he cares about most - have a hard time getting along. The ex-Avengers want to return to America, and Tony has to choose how to treat his old family as they ask for his help. It might be easier to be alone, in the long run, but the advantage of having a family that you chose for yourself is that they’ll convince you to stay, in the end.
