Aww, caring big sis Anna! I really want to see more of her, both of them helping each other out. I think though I almost like the human AU more, because they're allowed to care more, Anna's allowed to care a lot.

OH YEAH. Like in Mystery Spot's Trickster AU where Bobby says to Sam You gotta kill someone to get Dean back, and then You gotta kill me, and there's the Choice. DEFINITELY.
