I really love the idea of Dean having to follow Sam around as Sam's inquisitiveness got him into all kinds of scrapes. I could see Dean being outwardly irritated, and probably inwardly, too, lol, but deep down being glad Sam had that yearning for knowledge outside their given track.

Yeah, Bella (I was spelling it Bela after the Bela Lugosi reference :D) is not high on my awesome list, but she's not low on the suck list either. I do like her better than Ruby, I suppose, so I guess we'll see.
