I'm looking for a sad story where Sam became a lawyer and is with Jess, but he still occasionally sleeps with Dean, who visits him and insists on Sam going hunting with him. Finally, when their father goes missing, Dean gives Sam an ultimatum, Sam says "no" and he never sees his brother again. I remember that the last scene of the fic was set some years in the future when Sam thinks of his twisted relationship with his brother and wonders whether he should tell Jessica about it because (as far as I remember) he imagines that she would understand. This is all I can recall, except for the fic being rather agsty, depressing and sad. I've been looking for it for a really long time. Please, help!
