Hallucination or not, Dean's presence feels like a very real thing. "Gonna be honest. Not feeling my best right now," is his tired reply. He looks over at his brother (his hallucination or whatever, it doesn't matter because it's Dean) and for a second he's right back at that church, being dragged across the ground and propped up against the Impala.

He brings a hand up to shove the hair out of his face, inhaling deeply. Okay, he needs to focus, dammit.

Glancing back at Dean, he knows a good way to set his mind at ease. "Got holy water and some silver?"

First things first. It's still so ingrained after all this time, the gamut of tests to prove that neither one of them is some kind of supernatural dick trying to play body swap.
