Raoul! "Yes?!" I'm giving you your cue, you dizzy little lizard. "Ooops!" Rrrrgh.
So, ANY-way, aside from the... "GOOOOOOOOOOOOOOORE!" ...there's little else inside the coffin. Well, except for the rapidly decaying corpse of Mother Milligan, of course! DUN!
La Casa Del Crap. The already-tense situation rapidly escalates into one of mad panic on all sides as "Mother" "Milligan" pleads with her "son" to believe her and Crazy Sammy hisses, "Get away from her!" from the other end of the room and Secretly Evil Adam waffles and vacillates between the two until Adam snatches the sawed-off shotgun from Crazy Sammy's hands and starts flailing around with the thing until Crazy Sammy bays, "SHOOT IT IT'S NOT HUMAN!" And then? Why, only the most awesome moment of the entire episode when first it aired: The frightened, frantic expression on Adam's face melts into a smirk of conspiratorial glee, and he lightly admits, "I know," right before bashing Sam's face with the butt of the gun!" "VIOLENCE!" shrieks Raoul, in such a tizzy at this point that he's forgotten for whom he's meant to be rooting. "WANTON ACTS OF UNREPENTANT VIOLENCE AND EEEEEEEEEEEEE!" And as Raoul collapses into a temporary faint upon his overstuffed armchair, Openly Evil Adam smiles sideways at his "mother." Dun-dun-DUN!
Meanwhile, back in The Underground Chamber Of Super-Smart Morons, Dean hoists another coffin lid to find...Real Adam's rapidly decaying corpse! By the way, it looks like the poor kid is missing most of the lower half of his body, a development Raoul would no doubt find positively enthralling had he not passed out from all of the generalized excitement and awesomeness sixteen seconds ago. In any event, Distressed El Deano stifles a gag and whips his horrified head around directly into the penultimate METAL TEETH CHOMP!
Sidebar: Seriously, I had no idea that particular twist was coming when this episode first aired last Thursday evening, and the way it played out was just ridiculously awesome, mainly because of Jake Abel's unexpectedly adept performance throughout the evening, so bravo to him. Unfortunately, because I now know of the twist's existence, recapping the earlier Adam scenes has been both a chore and a bore, because as I noted several paragraphs ago, it makes no sense for Adam and his "She's My Mother AND My Sister!" beastie-thing to string Our Intrepid Heroes along the way they did for the better part of the hour. Why not just kill Sam the instant Dean leaves them alone with each other, and then go after Dean later? Why wait? It reminds me of the first time I realized the idiot demons on Charmed should just take out The Glamorous Nitwits from afar, with high-powered sniper rifles. And it's always a bad thing when Supernatural reminds me of CANCELLED!
