Dean spies on Sam and NuRuby as they try to interrogate a demon about Lilith; witnesses Sam conduct an exorcism via mojo, and confronts them both. Even better, he later punches Sam out for playing with fire, but it never turns into a full-blown fight. Crap. My money was on Ginormatron. Instead they talk, and Dean lectures Sam about going down a slope so slippery that even Dean's angel is worried about it. They're interrupted by a call from Travis, an old hunter friend of John's who has a busted arm and needs the boys to check out a Jack Montgomery in Carthage, Missouri. A cheer goes out from the fandom for an actual Monster of the Week episode. On the road, Dean tells Sam about his trip back in time, and Sam accidentally spills that he's known for about a year that he ingested Azazel's blood as a baby. Dean's furious that Sam's been keeping so many secrets from him. The audience is stoked that the secrets are finally coming out.
Jack Montgomery is so hungry he could eat a horse, raw beef, his wife; whatever, he's not picky. He's never felt better in his life, except for when the beast within him is trying to exit through his spine. Being a Rugaru agrees with him. He's a sure bet in bar fights and no longer needs to de-shell his peanuts. At a motel in Carthage, we learn Jack's back-story from the aforementioned Travis, who killed Jack's biological father 30 years ago. Rugarus run in Jack's biological family and come of age at 30 ["There should be genetic testing for this sort of a thing now." -- Angel], but posthumous son Jack was given up for adoption and Travis finally tracked him down. The only way to stop a Rugaru is to burn it alive. Dean is disgusted but game. Sam slams on the brakes. He finds some information to suggest that if Rugarus never take a first bite of the long pig, they can control their inner monsters. Sam wants to inform Jack of what's going on with him, and give him a chance before they roast him alive. Sam is projecting so badly, even Dean knows it.
At some point, Sam and Dean have another pissy argument, but there's no more punching. Boo! Hiss! They then confront Jack at his home and it goes just about as well as you'd expect. Later Jack stalks a pretty young woman, and almost kills her, but stops himself. Too bad Sam and Dean don't realize this until after they break down her door. When Jack gets home, Travis is there waiting for him. He's got Jack's wife Michelle tied up, and he's going to burn both of them alive, because Michelle is pregnant. Jack begs for his wife's life, but Travis won't be around in another thirty years so he intends to end Jack's line, now. Jack draws on his monster-strength to set himself free and save Michelle, but sadly, for Travis, this leaves him with a powerful hankering for… well… Travis. Raoul must be thrilled with the gore because there are already three messages on my machine. Michelle's no Raoul, so she flees the scene in terror. Dean and Sam show up and find what little remains of Travis's remains. Jack overcomes them, but he's still struggling not to let the Rugaru win, so he doesn't eat them up right away, even though they're nummy treats. This gives Sam time to break out of the closet where he's being held and save the unconscious Dean -- who wakes up just in time to see Jack Montgomery turn into Jack O' Lantern.
On the road again, Dean tries to apologize for being hard on Sam lately, but Sam cuts him off. He doesn't want to talk about it, which causes Dean to faint, crash Metallicar, and they both die. Or maybe Sam just gives a speech about dealing with this demon blood that's in him, that isn't in Dean. Sam declares he's done with his powers. Dean thanks him, but Sam says he's not doing it for Dean, God, angels, or anyone. It's his choice.
Stayed tuned, because next week we get a classic movie monster episode, and thirty years from now, we'll see Dean and Sam kill Jack's spawn.
NOW! Last week's episode ended with a "To be continued..." card, so the newcomer might be expecting the second half of a two-parter. The old-timer calls the newcomer a sucker, knowing we'll be lucky to get any continuity at all. Guess what, old-timer; it's your special day! Maybe you should play the lottery, hit a casino, or if you're feeling extra lucky, buy some stock.
At a dingy warehouse, Ruby and Sam hold a demon captive; it is tied to a chair set under a Devil's Trap. Sam wants to know where Lilith is, but his prisoner just says, "Kiss my ass." Sam tells it to watch itself. How would one watch oneself kiss one's ass, never mind actually kiss...oh. Okay. Anyhow, the demon figures it has nothing to lose, probably because it has nothing to lose. "Why, huh? Because you're Sam Winchester -- Mr. Hero, and yet here you are slutting around with some demon. Real hero." Sam tells him to shut his mouth, and I kick him, because I want this cleared up once and for all. Mr. Demon, when you say 'slutting around' are you being figurative, if crude, or is something more going on with those two than backstreet hunting? The demon completely ignores me, damn that thing, and keeps up with the non-specific taunting. "Tell me about all those months without your brother -- about all the things you and this demon bitch do in the dark. Tell me, Hero."
Sam, unlike Ruby, has several facial expressions. She's been holding the impenetrable steady deadly gaze of I Might Be Dead Inside But Who Knows. Our boy, though -- he's flaring and contracting his nostrils, so either he's incensed, or holding in a sneeze. He stretches out his enormous right hand, and the demon is exorcised from its host before we get the dirt. No fair, Sam. Hey, are your silent exorcisms in any way related to silent birth, because they are so different from other exorcisms in this series. When a demon leaves a host under its own steam, or via the exorcism rite found in the Rituale Romanum, it flies upward out of the body at great speed. During your new, improved exorcisms, the hosts appear to have the dry heaves, and the black fog of evil essence descends to the floor, and scorches it. Sam ignores me. He's "busy" or whatever. After it's over, the victim/host collapses; and Ruby smiles. Okay, that's an overstatement. There was definite eye movement, though. Sam almost smiles back, but he's still winded, and it's not like she gave him much to go on. We see something lurking in the shadows of the warehouse. That something is Dean! Sammy's in trouble, now. I ask Dean if he saw that. He doesn't answer, but from the angry look on his face, I'd say that's a yes. Crows caw, a woman screams and the wing-y title card flaps its way onto the screen.
