For this prompt at avengerkink: "Some time after the events of the movie, somebody sits the Avengers down together to go through some standard SHEILD paperwork. Of course, because it's SHEILD, the standard paperwork goes way beyond listing an emergency contact. To whom would they give prospective consent in case of a fuck-or-die/sex-pollen situation? Who would want appointed guardian if they're de-aged? If they're permanently transformed into a housepet? And so on...
They discuss the questions and their answers with one another."
Many pairings implied/discussed.
