AU Meme: After Sam falls into the cage, Dean asks Cas for one more favor. On Dean’s days off, he visits Sam in different time periods, even if only for an hour or two. Sam never tells Dean about these visits.
bettythetl has written a wonderful, short-ish fic for this post-season 5 AU. Very interestingly from Sam’s/Adam’s point of view in the cage, which I thought was awesome!
There’s also a “The Time-Traveler’s Wife” inspired AU Wincest fic that I saw circulating around very similar to this AU that can be found here: [x]
