Thank you! I have no idea, either *peers at LJ warily*

*nodnods* Fair! I guess I think of backstory as...before canon, and "canon" is really the movies, not just Avengers, as Natasha is in IM2 and Clint in Thor.

I think "fall out" works, but I suspect how it is tagged is up to the author, like the other tags are. I'd go with "immediate fall-out" and "consequences of the events are dealt with" - just refereed to would be general post-canon work.
