...the Impala, where the barmaid directs our attention to the lurid bloodstain now spreading across her white beater. "EEEEEEEEEEEEE!" "Didn't I tell you to turn back?" she asks Partially Reconstituted Sam. "That you wouldn't like what you found?" she reminds him. Partially Reconstituted Sam offers her his profuse apologies for shooting her in the stomach, but now that we know for a fact she's not real, who gives a shit? The ever-nameless barmaid dematerializes in a haze of squiggles, leaving Partially Reconstituted Sam alone.
Meanwhile, back at the ranch, Catatonic Sam reclines peacefully on the panic room's cot while Dean gets blotto on Bobby's scotch. "Atta girl! [Slurp!]" Bobby eventually returns with Belthazor in tow, and everybody's favorite Eurotrash angel makes with a few snide remarks regarding the decor before getting down to business. He passes Dean a slip of paper upon which are written the coordinates to Castle Crowley, and best as I can tell, it's some nonexistent address in Kansas, but that's not important right now because what is important right now is the fact that Belthazor refuses to flutter Bobby and Dean over there. He's stuck his neck out far enough already, thank you very much, especially considering how powerful Castiel's become, so Bobby and Dean are on their own. With that, Belthazor bids them good luck, and scrams.
Castle Crowley. Crowley himself enters and presents Castiel with a Mason jar filled with that nasty monster-and-virgin blood mix they'll be needing for their evening ritual, and after Castiel quietly thanks him for it, he announces they'll be renegotiating the terms of their agreement. Long story short, Castiel gets all of Purgatory's souls, and there's nothing Crowley can do about it, so nyaaaaah. Needless to say, Crowley does not take this news well at all, going so far as to harshly remind his erstwhile partner that Castiel is "the bottom" in their relationship. Of course, the reference goes flying straight over My Sweet Baboo's feathery head, and Castiel replies by offering Crowley one of two simple options: "Flee, or die." Crowley chooses to flee, leaving My Badass Baboo all by his lonesome down in Crowley's baroque dungeon.
