Nora: Your number is not working, by the way.
Sam: Right, we, uh, we've had some technical difficulties, phone issues.
Dean: It's a monster problem, really.
Lucifer: Oh well, that's every cell phone Dean's got. One of them should have picked up, right? Big brother's probably dead.
Sam: Shut up.
Lucifer: He said "shut up" to me.
Lucifer: That's what I'm talking about, Sam--real interaction again. I miss that. The rapier wit. The wittier rape.
Sam: Yeah, well, new plan. Tracking spell. Bavarian, Egyptian, I don't care. Dealer's choice. Use the flesh of the body to find the body. And Dean. Do you want the ear, or the kid?
Lucifer: You're giving me chills.
Dean: (to demon) Is this what you do? Find postal workers, make them go postal?
Jeffrey: (to Dean) You were so desperate to fix the world back then. It kills you that people keep getting hurt. And you just can't stop it.
Dean: (before falling asleep) Screw consciousness, that's what I say.
Lucifer: (to Sam) You let me in. You wanted me, partner. So you think you can use your little tricks to banish me again, like that? No. I do believe I've got you, bunk buddy. Got my finger wiggling around in your brain pan.
