I'm looking for a specific story that hopefully I didn't just imagine. Sam (somehow--I can't remember) escaped from the cage and returned to earth. Because of his trauma, he had amnesia and basically wandered around homeless. Somehow Dean found him (I don't think he was looking for Sam, possibly crossed paths while hunting something with Bobby). And I vaguely remember Sam and Dean staying in the same motel, but different rooms. I couldn't say whether Sam was staying there and that is where Dean found him, or if Dean found him and gave him a place to stay and rest up. Thanks for your help! I know that if this is a real story, that someone knows about it. I am positive that this is a gen story and probably was on ff.net.
