I can't decide what my favorite part of this is. God being Dean's father-in-law? Satan his brother-in-law? The fact that that conversation could totally make for a plausible episode? Naw, let's be honest, it's the "when."
SO SAD. I mean can you imagine all the kids bullying sherlock and calling him names and going to the library to see why everyone detested him? He's a high-functioning sociopath...he did his research *goes to corner to sob*
