[ Having Castiel pass out on him is bad in a couple ways. One, he's completely on his own with this new guy and by the looks of him, Dean figures he could use backup, even if it's by way of a religious freakazoid. Two, Dean isn't super sure Cas passing out right now is the right thing to do - yeah, he needs rest so his blood count will slowly replenish, but Dean can't be sure of just how much was lost, so it's also possible Castiel just slid into a coma that he won't wake up from.

So, that's worrisome.

Mostly though, with Cas on the outs, Dean's by himself in this predicament and it looks...well. Bad. Like Dean just tortured him or something, which isn't the case, at all.

More like they tortured each other by way of trying to play combat medic in the backseat of an ugly ass car. ]

What can I say, I like to stay out of sight out of mind.

[ Dean likes this guy even less than he initially liked Castiel. There's something slimy about him, something that's ersatz in the way he smiles and speaks to Dean. It makes his skin crawl far more than Castiel ever did, the knot in his stomach swelling in size. ]

He's alive. I stitched him up, but he needs a blood transfusion, soon. You don't happen to have a field kit in that fancy car of yours, do you?
