"Son of a bitch!" Dean growls roughly. Castiel just stands there nose to nose with him, blinking, like he really doesn't understand about personal space.

Or blind spots.

Dean doesn't like surprises. Never has. Sam thinks it's something Dad trained into Dean. It's not. Surprises usually mean blood, pain, and screaming. Broken bones, more scars. That's the best case scenario.

Cas means well, Dean knows he does, but he can be nerve wracking sometimes.

One of these days, that dark little voice inside Dean's head says, you'll wish it was Cas standing there.

One of these days it won't be.
