I know I've asked for similar recs before, but does anyone know of any stories where one Winchester is possessed and infiltrates the other(s)? I love it when there's a gradual realization that something isn't right, especially if the demon messes with the others while undercover. Or just fanfic where one of them is possessed in general, I'm easy. :)

Possessed!John and/or possessed!Sam are especially love, but possessed!Dean would be nifty also. Even possessed!Mary if one knew of any! I'm a sucker for hurt!Dean, so if any of that came up during the course of the story, my week would be made.

As a second request, does anyone know any stories where Sam really seems to get how distant he and Dean have become in season five and works to make things better between them? I'm looking for some fix-it fic, I guess, but I really want Sam to make the first move at reconciliation.

Thanks in advance!!
