I guess you must be right about the deal, but earlier in the season Dean seemed to think that even knowing Sam was researching a way out could kill him...let alone helping him do the research. So they kinda changed their mind a bit. But, hey I'm a forgiving sort. :)

I never really read the episode stuff at SVS, but I'll take a peek. Was the site down yesterday or was it just me?
EDIT: It's still unavailable to me. I just get a "problem loading page" screen.
