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.
Entirely Unnecessary Denouement. We've arrived back at Addled Kevin's house just ahead of Addled Kevin and his angelic escort themselves, and we watch for a bit as Tiger Mother chats with Random Local Police Official Who Is So Obviously A Leviathan until Addled Kevin and his angelic escort flutter on in from the lush coastal rainforests of Montana's Rocky Mountains. Random Local Police Official Who Is So Obviously A Leviathan promptly slaughters Addled Kevin's angelic escort, then morphs into Leviathan Edgar form to pretty much go, "Muah! Ha! Ha! Ha! Ha! Ha! Ha!" until we finally cut to black.
Not bad, as far as these sorts of exposition-dump episodes go, but I can't shake the feeling that all of this should have happened a hell of a lot earlier in the season. In fact, they pretty much could have skipped every single installment between "Death's Door" and "Of Grave Importance," and I'm positive nobody would ever have missed any of it. Ever.
Next week, more late-in-the-season delays as Our Intrepid Heroes try and apparently fail to score a couple of blood vials from Crowley and that vampire guy I thought was dead. Have fun!
