After that interview with Carver, I'm starting to have some serious Orpheus (Sam) and Eurydice (Dean) thoughts. Because what if not looking for Dean is how Sam gets him out of purgatory? Okay, it's not technically how the myth goes, but it would fit with the whole "this season people might think one way about one of the brothers in the beginning. Again, it goes along with perception. [...] What you think might be a bad thing - I don't think you'll think that as the season goes on. We are playing with expectations" thing Carver is saying. Anyway, I'm intrigued.
