Seriously, someone needs to make up a line diagram or something to keep track of all this stuff. Maybe Sam could do that for us, as he tries to figure out who some of these demons are and how they connect to him. The dude has demons who want to kill him, demons who want to help him, hunters who want to kill him, hunters who want to help him, and the FBI and heaven knows how many police departments wanting to throw him in jail. I'd be keeping a tally sheet in my wallet if I were him, just to keep it all straight.
