Sure as he is about the momentary safety of this place, Dan's still speaking softly, right against Marcus's ear. "Think of it like turning a wheel," he says. "The demon's trapped in the middle, can't leave without someone inviting him, to a certain extent. You and I are on the wheel, though. And we're going to turn it until you're outside, where you can tell Sam the name and catch your breath."

He leaves the part where he stays inside with the demon unspoken, though it's not like he thinks Marcus won't understand.

"An hour, and you come back to me and we turn the wheel again. You're the one that knows how to beat this thing the best. You're the exorcist. Get ready to fight."
