Castiel’s body, possessed by the Leviathans and leaking black ooze, walks over to Dean, who calls to the unconscious Bobby. As Bobby wakes up, Dean distracts the Leviathans and says that the host body will soon explode. The Leviathans say that they’ll be back for Dean and stagger out of Crowley’s lab, unaware that down the hallway, Sam is struggling with Lucifer. Lucifer tells Sam that the two of them are real, but everything else is a hallucination and Sam is still in the cage in Hell...Read the full recap
Dean: (about Castiel) So he's gone.
Bobby Singer: Yep. Rest in peace. If that's in the cards.
Dean: Dumb son of a bitch.
Bobby Singer: 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 Singer: 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 Singer: 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 Singer: 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 Singer: Well, either Sheriff Mills is having an Obamacare-insured opium dream, or something's eating folks down at Sioux Falls General Hospital.
Sheriff Jody Mills: Bobby Singer. My hero.
Bobby Singer: 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.
Bobby Singer: Whatever they're up to, it ain't--ain't about going Mothra down Main Street.
Mothra is one of the giant Japanese monsters and first appeared in the movie of the same name in 1961.
