Ridiculously Scenic Rustic Homestead. Aftermath. Castiel declines Anaias's kind invitation to rejoin the garrison just as Addled Kevin finishes translating The Metatron Stone. Our Intrepid Heroes thank the kid kindly for his efforts, and then Anaias orders his two remaining gentleman colleagues to escort Addled Kevin back to his home, where a squad of angels will watch over him until this goddamned season finally ends. And once all of those guys have departed, and after Meg's temporary and never-explained absence is duly noted, Sam reads the following from Addled Kevin's translation: "'Leviathan cannot be slain but by a bone of a righteous mortal washed in the three bloods of the fallen.'" "A bone of a righteous mortal," huh? Dirty! Also: A typically simple and straightforward vanquish for this show, right? "It says we need to start with the blood of a fallen angel," Sam eyebrows, and My Giddy Baboo happily obliges them with a magically-appearing vial he presents to Dean. And with his work here done -- for now and only now, I hope -- Castiel flutters off towards points unknown.
