I KNOW. I am so proud of Sammy right now. Like, bursting with it. And I love how we got that little contrast between Dean and Sam in the panic room, where Dean said he'd left Sam to rot in there. Sam goes to Ruby to kill Lilith, thinking he's doing the right thing (though he's not) and Dean freaks out, fights him, doubts whether or not he's his brother, and just basically pushes him into it. Then Dean tries to go off and say yes to Michael, thinking it's the right thing (though it's not) and Sam tell him that he still has faith in him, and that Dean is still his big brother---and drags Dean from the edge.

That's my Sammy!!

I hope this means the boys have grown and learned from this. Better together, boys, better together. Especially since you're soul mates and all. :D
