Summary: John and Dean have to identify a body.
Author's Note: Based on this prompt: I just watched season 1 again, and in the episode 'Benders' I think it was practically Sam's fault that the dad died as he got out, took out the brothers and the father, whatever.
So I think that if the brothers got outta jail or escaped they would come after Sam as pay back. So they tortured Sam or they hunt him like they were going to do the first time or anything really, your call on that :). It can also be a deathfic, don't mind. Don't care what season, thou not within season three :P
The ending is open to interpretation.
