#1. OmniscientPhoenix has an excellent (heartbreaking) WIP, updated pretty regularly, THE COLDEST CIRCLE IN HELL. (Sam/Lucifer, Sam/Dean) http://archiveofourown.org/works/4820024/chapters/11036540
Summary: Sam Winchester returned from the Cage barely held together by Death's wall. No one knows that there shouldn't have been anything left after 18 months in hell. Lucifer offers Sam a deal on his first night in hell; if Sam stops fighting and becomes Lucifer's plaything, Lucifer will give him a reward. One day a year Sam gets to relive his best and brightest memories. Sam takes the deal and never regrets it. That is until he goes home and Castiel shatters the wall. He's left with horrifying memories and guilt over his deal with Lucifer. He believes he deserves everything that happened in the pit and he regrets the day he was ever weak enough to give into Satan. Unable to forgive himself, the hallucinations are closing in and Sam is prepared to end it all. Only Dean can save Sammy now and he's not about to give him up when he just got his baby brother back.
