I'm looking for a longish gen story that was posted on LJ (at least two parts, IIRC), in which Sam was recruited by a secret agency of some sort while he was in Stanford and became an assassin/spy. They've blackmailed him into it by threatening to arrest John and Dead, so Sam drops out. It's a pretty angsty story and in the end, he decides to go back to the agency and leaves John and Dean. Help plz? It's been driving me nuts and it seems my google-fu has failed me this time. *sad puppy dog eyes*
