Oh, I think we as the audience have seen plenty about how much Sam cares for Dean through the whole show. Sam's concern, his "nagging" is mostly what Dean sees though. But lately yeah, not so much while they've been fighting, Sam's been holding back. Except for caring that Dean's in immediate physical danger.

I liked that the Crowley and Sam interaction was so murky, full of possibilities.

Hey, maybe they can get Jesse the AntiChrist to do the Magnus zoo cleanup for them? That'd sew up two plot holes at once! I'll add that to my tatto/painting the Impala fic, fix it all up at once...(maybe/not maybe kidding)
