Hi. I'm looking for a specific fic where Sam kept Dean from going to Hell. I've been searching for the fic for a couple years and haven't been able to find it anywhere. I can't remember the title or author, but I believe it was on livejournal. In the fic Sam made a deal with a demon to keep Dean safe. He had to get Dean to a specific location (I believe there was a circle involved somehow) and to do this he told Dean there was a hunt. In reality they were hunting the demon Sam made a deal with (or a cohort of said demon). This demon took Dean somewhere and used him as a cagefighter (Dean was still human I think). As Dean was fighting Sam was embracing the powers of the demon blood in his veins. He became a hot-shot powerful leader of a group of demons.
Sam and Dean eventually meet, but Sam doesn't remember Dean at all. Dean ends up going with Sam and Sam's band of demons somehow. I think Sam starts remembering Dean and this makes him angry.
As I said, it's been a while since I read so the details are kind of vague. I remember loving it and would really like to read it again. Any help would be appreciated.
