Yeah, I was glad for the confirmation on the Meg story-point too.

I was also surprised that Sam looked into the Bobby thing - especially at the time when the beer thing happened, Sam seemed even less suspicious than Dean was.

I'm also wondering how Bobby will be used in the plot. Maybe once they figure out how to talk to him, he'll be able to tell him what those Leviathan plans were!

I think that's why I like Garth so much - and why I'm curious as to his backstory...he's such an atypical Hunter, in that he doesn't seem to be irrevocably emotionally scarred. :P
