Dean: So (Castiel's) gone.
Bobby: Yep. Rest in peace. If that's in the cards.
Dean: Dumb son of a bitch.
Bobby: Well he was friends with us, wasn't he? Can't get much dumber than that.
Dean: Wait, I got it. Why did the Devil holodeck you a whole new life when he can just kick your ass all over the cage?
Sam: 'Cause, as he puts it...
Sam and Lucifer: You can't torture someone who has nothing left for you to take away.
Lucifer: Very good, Sam.
Dean: Okay, fine. But this Malibu Dream Manson that he--he--he makes for you to take away is this post-apocalyptic mess?
Lucifer: It had to be a mess, Sam. Or you wouldn't believe it was your life.
Bobby: Of course, lost one of the best friends you ever had. Your brother's in the bell jar. And Purgatory's Most Wanted are surfing the sewer line. But yeah, yeah, I get it, right. You're--you're fine.
Bobby: Of course, if at any time you want to decide that's utter horse crap, well, I'll be where I always am. Right here.
Dean: Well, you want to do couples' yoga or you want to get back to hunting the big bads?
Bobby: Shut up. Idjit.
Edgar: You got yourself an awfully small body.
Annie: Too small. She didn't know anything. Can't even see over the counter.
Edgar: This one, Edgar, Edgar worked on something called a demolition crew. Watching things blow up is apparently very satisfying.
Annie: Annie knows where baby comes from. Disgusting, by the way.
Sam: Okay, if this is some dream and you got power over it, why don't you just end it?
Lucifer: End it? This? You not knowing what's real, the paint slowly peeling off your walls. Come on, man, this is the sweet spot. Why would I end it? Not like we got HBO in the Pit.
Bobby: Well, either Sheriff Mills is having an Obamacare-insured opium dream, or something's eating folks down at Sioux Falls General Hospital.
Sheriff Mills: Bobby Singer. My hero.
Bobby: That's the roofies talking.
Dean: (to Sam) Hey, I am your flesh and blood brother, okay? I 'm the only one who can legitimately kick your ass in real time.

Referencing the giant moth-like Japanese monster first seen in the 1961 movie Mothra. The monster is occasionally seen as a mammoth egg, which hatches into a giant web-shooting larva, and eventually matures into the familiar moth-like form. Originally she could generate gale-force winds and lift other monsters into the air. Later in the 90s, she was given additional powers to fire energy beams from her antenna and generate electricity.
Dean: Why did the Devil holodeck you a whole new life...?
