Dean watches curiously and a little warily. He's used location spells before though he hates using them as he hates pretty much all other magic. Humans used magic and humans were crazy sons of bitches in his book and he'd rather deal with a frigging pack of Wendigos than a human with a magic book. It takes him a moment but he realizes that James means to find Sam and Dean doesn't know if he likes that at all. He'd planned on getting to Bobby's then ditching the guy to haul ass and find his brother.

But this guy who he doesn't know and certainly doesn't trust knowing where Sam is? Yeah no, Dean no likey. He has little time to say anything, though when the knife spins and pulls from the man's grasp and slams into the map and the table. It's sudden enough that he sits up sharply and stares at it, then jerks back himself when it lights up.

Dean snatches the picture back, smooths it over to make sure there are no scorch marks, then glares at James. "The fuck was that? What the fuck just happen? What does that mean? And the next time you want to use that witchcraft fuckery you let me know so I can get the hell outta Dodge. I don't deal with witches."
