Samuel is a puzzle to me. And it REALLY bugs me there hasn't been a 1973 reference- surely meeting your yet to be born grandson and hunting with him right before you died would deserve a mention? I really hope more goes into his backstory, especially a mention of Deanna and more explanation as to how he showed up in 2010 and whatnot.

I'm glad Bobby blew off Dean too, given the circumstances, but I still hope it's brought up.
