Subtle again, Dean ! EDIT: episode 08x10 What happened?? Where are all the fanfics?? This is a serious issue that needs to be addressed Dean could have taken Cas out on a date and we missed it. #Destiel
You know what is really interesting? Dean doesn't put his back to John to talk to Sam. No, he puts his back to Sam and steps between John and Sam in a protective position. His body language is essentially taking Sam's side in the argument. Why? Because he knows he can continue on without John, but not Sam.
I really just love that Dean feels the need to protect Cas, even though he thinks he is still an angel. I get him protecting Sammy, it's his little brother, but him protecting this powerful angel (as far as he knows) is so sweetly silly!
I'm actually kind of afraid of this. At least when they had Dean in their lives, they stood a chance against all the Big Bads. Now he's taken himself away, and all the evil guys know about his family...and they don't know how to fight them anymore.
