FAYETTEVILLE, NORTH CAROLINA

Scene opens with dripping water in an unknown location. Then we see hair hanging down, with a woman hanging upside down, watching a man come toward her down the hallway. The camera switches back and forth from her struggling and panicked eyes to the man coming down the hallway. He places a bucked underneath her, then slices her throat open with his bowie knife. He catches some of her blood in his hands, and we assume, drinks it.

BUNKER

In the library Sam is on his computer and on his screen, where he's researching "Biblical and Far East Studies." Dean and Elena enters and Sam quickly closes his computer.

"Hey, check it out." Dean Says

"Hey." Sam Says

Elena and Dean looks at the laptop then back at Sam.

"Porn?" Elena Says

"What? No. l-it's nothing." Sam Says

"Hey, look, no judgement from me. Just, you know, not where we eat." Dean Says

"Dude, it wasn't porn." Sam Says

"Okay, "erotica." Whatever. Zip it up. Check this out." He hands Sam his tablet with an article about a soldier who has died "The vic was trained in Krav Maga and jiu-jitsu. Still ended up with her organs drained, and the marrow was sucked completely out of the bones." Dean Says

"So...cannibalism. You guys thinking a Rugaru?" Sam Says

"Or a God, maybe." Elena Says

"I'Il go dig up my pencil-neck suit." Dean Says

"Wait, wait, wait. W-what?" Sam Says

"What, is this not weird enough for you?" Dean Says

"Well, yeah, it's weird, but, um, l mean, we..we..mean..." Sam Says

"What?" Elena Says

"Nothing." Sam Sighs

"Great. 10 minutes. I'Il meet you guys in the car." Dean Says

"Great." Sam Says

IMPALA

Dean's driving, and Sam's on his cell phone, Elena looks over his shoulder and looks at his phone.

"Sam!" Elena Says

"Huh what?" Sam Says

"Your so nose deep in your phone, like your texting someone and god knows you ain't texting anyone." Elena Says

"I was texting someone." Sam Says

"I know what you're doing over there, and it ain't porn. Look, man, we have checked every website, okay? We've checked it twice. Sammy, when we work a case, there's always that..that point..when we have to face the truth, right? Even if we don't like it. Well, truth is..."He holds his arm out, indicating the Mark of Cain "There's no way around this. We saw what happened to Cain, okay? I'm not happy about it. But I got to move on. So l'm gonna keep doing what we do...while l still can. And l'd like you both to be there with me." Dean Says

FAYETTEVILLE POLICE STATION

Dean, Elena and Sam enter through a door. A group of police officers are standing around talking and enjoying pieces of cake.

"Agents, I gather." Sheriff Says

"Uh, was it the suits, or do we give off some sort of a Fed stench?" Dean Says

"I-it's the suits. What can l do for you gentlemen and lady?" Sheriff Asks

"Well, uh, we are here investigating the death of private Jackie Prescott." Elena Says

"Shoot. You drove all the way down from D.C.?" Sheriff Says

"Mm-hmm." Dean Says looking at the cake

"Yeah, we did." Sam Says

"Well, then sorry to waste your time, agents, but we wrapped that one up. Guy that did it was a special forces officer: Rick Willis." Sheriff Says bringing over a file

"What makes you so sure it was him?" Elena Asks

"His fingerprints were all over the storage room out on the base where he did it. He even left his dog tags by the body." Sheriff Says

"So, is he in custody?" Sam Asks

"No, bastard drank a boatload of gasoline, then lit himself on fire." Sheriff Says

"Well, that's a hell of a way to go." Dean Says

"No kidding. Left a wife and a baby. Third suicide we seen in six months. Military town. Would you like some cake?" Sheriff Says

"Mm. Yeah." Dean Says

Sam cutting off Dean's access to the cake "No, uh, y-you know what? Uh, we're okay."

"No, it's really good. My partner made it." Sheriff Says

"It looks great, but we're...no, we're all right." Dean looks on upset "Uh, we do have one more question. Were there any bite marks found on the body?" Sam Says

"No. Vic was killed with a Bowie." Sheriff Says

"Well, sheriff, thank you for your time." Elena Says

"Yeah." Sam Says

Sam, Elena and Dean leave the police station. The rest of the conversation is held in the hallway and the way out to the Impala.

"No bite marks. That rules out Rugaru. So what? A God?" Sam Says

"I don't like the sound of that. The guy Molotov-cocktailed himself. That's bonkers. That's like demon-possession bonkers." Dean Says

BETH AND RICKS HOUSE

Beth is in the kitchen with Sam, Elena and Dean sitting on the other side of the island from her.

"Rick did it. I'm not trying to say that he didn't. But..I mean, he just got back from deployment, and we've all seen what it can do to a soldier's mind. My Rick...when he's home and good...I have to kill the spiders, you know? Rick was a kind soul. He never took more life than he had to." Beth Says

"Did you, um, notice anything strange, weird, like, uh . . . violent mood swings? Or weird smells?" Sam Asks

"No. But..Rick was...he was so...He was thirsty." Beth Says

"Thirsty for what?" Dean Asks

"Water. He'd spend half the day drinking from the garden hose. And then, one night, I caught him in the tub drinking the bathwater. When l told him to stop, it was like he couldn't even hear me. And his skin, it got so dry it bled." Beth Says

"Did he see a doctor?" Elena Asks

"I took him to the V.A., but he just got on a list to get on a list. And then, he stopped talking...And just wasn't himself. I thought maybe it was PTSD." Beth Says

"Uh, we're very sorry." Elena Says

"You said that Rick was recently deployed. Do you have any idea where?" Dean Asks

"No, that stuff is classified. They don't even let the wives in on it." Beth Says

"Right. Okay, well, we'Il, um . . . We'Il leave you alone now, but if something comes up, anything at all, just give us a call." Sam Says

"There's one other thing. I ran into my friend Jemma at the supermarket. She's married to Kit Verson, a guy from Rick's team. She thinks Kit came back different this time. Kind of felt like we were dealing with the same thing." Beth Says

"Thank you." Sam Says

KIT AND JEMMA'S HOUSE

Sam, Elena and Dean are seated opposite Jemma in the living room.

"Kit's been going through some stuff for sure. Um, you know, it takes him a while to get back to normal, but he always does." Jemma Says As She hands both Sam and Dean a beverage

"Thanks." Sam Says

"And what about you? How are you holding up?" Dean Asks

"I'm okay...For the most part. You know, what happened to Rick and Beth, it...It's been hard. "There but for the grace of God," you know?" Jemma Says

"Um..May we speak with your husband?" Elena Asks

"He, um...He went out last night, but he should be back any minute. You know, Kit, he comes back from these deployments, and he needs his space." Jemma Says

"So he's been out all night?" Dean Asks

"Well...Yeah" They share a look "..God. I can't even convince myself. Um..I'm worried. This isn't like him." Jemma Says

"Has he been thirsty? Like "drink out of the dog bowl" thirsty?" Sam Asks

"How did you know?" Jemma Says

As Sam, Elena and Dean leave the house, they notice Cole is leaning against their car out front.

"Recognized your wheels." Cole Says

"What the hell are you doing here?" Dean Asks

"Jemma called me in. I've known Kit since we were military brats raisin' hell on the same base. He's a good man." Cole Says

"Well, no one's saying he's not." Dean Says

"Oh, really, now? So, what are you three, uh, here for, Jemma's sweet tea? You want to tell me why you're really here?" Cole Says

"We're working a case." Elena Says

"Oh, Kit's case?" Cole Says

"Honestly, we're not sure just yet, but, um, it's looking like it." Sam Says

"Mm. Says you." Cole Says

"There's a murder-suicide in town. Your buddy Kit? Same unit as the killer. Same whacked-out antics. So.." Dean Says

"Look, we're not going anywhere, all right? And if you care about your buddy, you'Il let us handle this." Sam Says

"Mm. Nah, l think I'm gonna be coming with you." Cole Says

"Oh, the hell you are." Dean Says

"I got contacts. I can help." Cole Says

"You really can't." Dean Says

"For example, a friend of mine works military intelligence..owes me a favor." Cole Says

"Would he know what Rick and Kit's mission was?" Elena Asks

"Sure. And he'd tell me all about it." Cole Says

"Okay, fine." Dean Says

"No, it ain't. You know, l figure what's going on here..I stick to you three like flies on roadkill, make sure my buddy comes home in one piece. Look, l know what you three are thinking, but we are not gonna hunt my best friend, who happens to be a friggin' war hero, by the way. We are gonna find him. And that's the difference." Cole Says

"Hey, man, we're right there with you, okay? Kit's a hero, but..." Dean Says

"But you got to prepare yourself. Kit might not be Kit anymore." Sam Says

GAS N SIP

The scene opens with a man staggering into a Gas'n'Sip, grabbing a bottle of water, guzzling part of it, then throwing it down in favor of a larger bottle in a cooler at the back of the store. The man looks extremely sick, and the clerks are unsure of what to do.

"Uh, sir? Sir, you have to pay for that first! Hey!"He Knocks the water bottle out of his hand "Now, look what you ma . . .Whoa!" He Says

Kit, smashes a wine bottle and cuts the clerk in the neck with it. Kit smashes the store clerk into the cooler, then lick his blood up off the gas station floor, The other clerk dials the police while watching Kit.

"This guy just came in. Get to the store, man." He Says

SAMMY'S HIGHWAY CAFE

Sam is at the food truck and the vendor hands him his food, he walks over to the table where Dean, Elena and Cole are sitting and tosses Elena, Dean and Cole their food.

"Yo. Sustenance." Sam Says

"Thanks." Elena Says

"Listen, I got nothing on cattle deaths, freakish weather none of it." Dean Says

"So Probably not a demon." Sam Says

"So maybe it's just not your kind of thing at all." Cole Says

"Well, when in doubt eat." Dean Says

Cole gets a notification on his phone "Okay, here we go. I got an encrypted e-mail here from my friend at the M.I."

"And?" Elena Says

"Well Kit and Rick were sent to rescue an American P.O.W. Being held in Iraq the Najaf cemetery." Cole Says

"Cemetery?" Dean Says

"Bastards use 'em as a, uh as a prison. I got some footage here from the camera on Willis' helmet during his last mission with Kit." Cole Says

In the video, the camera shows two soldiers enter a mausoleum and find the soldier they were supposed to rescue, who aggressively attacks them.

"Okay, go! Down. Get down. Clear. Major Jones?! Major Matt Jones? Hey, right here. Hey, Major Jones, is that you? Hey. Hey, I'm captain Kit Verson. We're here to bring you home, man. Oh, what the hell?! What the hell was that?!"

"I'm guessing that didn't have a happy ending." Elena Says

"No, it did not. Mission failed. And that P.O.W. got shot by guards." Cole Says

"Really? That's what happened?" Sam Says

"That's the official story." Cole Says

"All right, so, Kit and Rick came back screwed-up. We know that much." Dean Says

"Well, and then Rick jumped the high dive. God, Kit." Cole Says

Dean referring Sam's phone ringing "What was that?"

"I set my phone to get local alerts." Sam Says

"Is it bad?" Cole Asks

"It's bloody." Sam Says

"All right, let's get out of here." Dean Says

GAS N SIP

Back At the Gas'n'Sip where Kit ate the store clerk. Sam, Dean, Elena and Cole are in the parking lot near the Impala.

"He licked the blood off the floor?" Cole Says

"Yeah, the soda jockey back there seemed pretty shook up by it." Dean Says

"Now, the description he gave medium build, brown hair that sound like the Kit you know?" Sam Says

"Yeah, it does." Cole Says

"Great." Elena Says

"This still sound like it ain't our kind of thing?" Dean Says

Coles phone rings and he answers "Hey, Jem."

"Cole, uh, the news said someone was killed at the Gas'n'Sip on Kenton." Jemma Says

"Yeah, I know. I'm here right now." Cole Says

"You are? W-what are they saying?" Jemma Asks

"Not much. Look, Jem. Um, I really can't talk right now. I'm sorry." Cole Says

"Wait. Do they think that he..that that Kit..did this?" Jemma Asks

"I don't know." Cole Says

"If he did, he isn't in his right mind, and you know that, Cole. You got to save him." Jemma Says

"I will." Cole Says

"I know. And, uh...And that's the only thing keeping me sane right now. I was thinking, you know, sometimes, when Kit wanted to be alone, he would head up north to his dad's old cabin. Maybe you could go check it out, and...and..and l'Il stay here
in case he comes home." Jemma Says

"Right." Cole Says

"Hey, Kung-Fu grip, you coming?" Dean Asks

"Hey, Jem, I got to go." Cole Says

"So, what next?" Elena Asks

"We hit every cop shop within a 10-mile radius, put the word out, see if we can't track him down." Dean Says

"And if you find him, what then? Kit needs help. He doesn't need a bullet, and he doesn't need a knife." Cole Says

"Okay. You know what, Cole? We know you want to protect your buddy, but..." Sam Says

"If he's a monster...we got to put him down." Dean Says

"That's the way it's gonna have to be, huh?" Cole Says

"That's the job. So, you in or out?" Dean Says

JEMMA'S HOUSE

Sam, Elena and Dean drop Cole off at Jemma's house. Cole exits the car "Thanks for the lift."

"It's better this way, all right? You keep her calm. We'Il keep you posted." Dean Says

"Yeah." Cole Says

"Hey, Cole. He shows up, don't try and be a hero. Call us." Dean Says

"You got it." Cole Says

Cole waits until the Winchesters and Elena drive away, and then he gets in his truck and leaves Jemma's. Sam, Elena and Dean hide in the Impala in the trees and watch Cole's truck drive past. Then they pull out and follow him.

"And you bought him dinner." Dean Says

KITS CABIN

Cole pulls up to the cabin and goes inside, searching for Kit. We see the Elena and the brothers pull up outside and quietly gather their gear before following Cole inside. Cole pulls out a flashlight and searches around the cabin, following a trail of torn apart rodents.

"Kit? Hey, Kit? Are you here? It's Cole. There's some real serious people looking for you, Kit. And they won't just want to talk. It's bad, Kit. And it's either me or them." He sees Kit sitting in the corner, with his back to the room "Hey, Kit. Hey. Hey, Kit." Cole Says

"I'm sorry. l can't stop." Kit Says

Kit attacks Cole just like the soldier from the video, We see Khan worms drop out of his mouth. Cole Screams while swallowing a Khan worm from Kit, Sam, Dean and Elena enters the cabin and rushes over to Cole and Kit.

One of the Khan worms falls to the grounds, Sam tries killing it with a machete but Elena steps on it with her boot. Then Kit throws Dean across the room and runs out of the cabin

"Wait, wait, wait!" Dean Says

"Oh, god. Oh, God. Ew. Something went down my throat." Cole Says

"All right, Cole, just try and stay calm." Elena Says

"Oh, God." Cole Says

"Cole?" Sam Says

"Something moved. It's alive, Sammy." Cole Says

"All right, well, we're gonna get it out of you, okay?" Sam Says

"How?!" Cole Says

"We'Il figure it out." Elena Says

Dean renters the cabin "Man, that was a dumbass move coming here alone. You know that, right?"

"Oh, l'm sorry. I should have let the machete buddies cut my friends head off." Cole Says

"Well, if you did, maybe you wouldn't be chokin' down a damn Khan worm right now." Dean Says

"What's a Khan worm?!" Cole Asks

"You think that's what it is?" Sam Says

"Or some sort of freak cousin." Dean Says

"Oh that's just peachy." Elena Says

"Freak cousin of what?" Cole Asks

"A couple years back, Dean, Elena and I worked a case. We got stuck in a cannery with this worm. It would get into people's bodies and.." Sam Says

"It was freaking awful." Dean Says

"Yeah." Elena Says

"All right, so you've been to this rodeo before. How do we kill it?" Cole Asks

"Worst case headshot the person it's in. Worm crawls out, we stomp it like a bug." Dean Says

"Is there a version where you don't cap me?" Cole Asks

"Yeah, uh, last time, electrocution made the worm leave the body." Elena Says

"All right, fine. Electrocution it is. I'm game." Cole Says

"All right. You two get to work, Elena and I'll go look for Kit." Sam Says

"Hey, hey, Sammy?" Cole Says

"Yeah." Sam Says

"If we can fix me, we can save Kit, right?" Cole Asks

"That's the idea." Sam Says

"Mm." Cole Says

Sam and Elena sighs then leaves the cabin, Dean looks over at Cole.

"You know that this is gonna hurt like a son of a bitch?" Dean Says

"Hell, I have a wife, a kid, and an upside-down mortgage to get back to. Whatever it takes, Dean-o." Cole Says

"Okay." Dean Says

A few moments later Dean and Cole carry in some car battery's and they set them on the table.

"Mm. So, last time you saw this thing, it turned people into killers, too?" Cole Says

"Yeah, except that one did a mind-control number on us." Dean Starts putting jumper cables on a car battery

"Damn. Day in, day out, you, Elena and Sammy saving people from things they just can't wrap their minds around...Hell, and nobody even notices it. Hell, at least I get a medal for my efforts. But you I tried to kill your ass." Cole Says

"Yeah, well, good times." Dean Says

"I almost took you off the map. Who would be saving me now?" Cole Says

"Yeah, well, let's not get too sentimental about it. All right, let's fire this puppy up." Dean Says

"Well, you say that like it's just another Tuesday." Cole Says

"Oh, buddy, it's only Monday." Dean snaps the jumper cables together so they spark

Cole puts the spoon in his mouth, leans back in the ragged recliner, and nods his head at Dean. He takes a deep breath, and then presses the jumper cable clamps onto Cole's forearms.

"Anything?" Cole Asks

"Last time, it came out of our ears." Dean Says

"And?" Cole Says

"I'm not seeing anything yet." Dean Says

"Do it again." Cole Says

Dean presses the cables to Cole's forearms shocking him, then he stops shocking him "All right, that sucker should have crawled out by now."

"Again." Cole Says

"I keep going, this is gonna kill you." Dean Says

"Again!" Cole Says

Dean looks away while he electrocutes Cole. His eyes role back and his jaw slackens on the spoon. Dean notices and immediately stops. Dean Starts taking Cole's pulse, and then slapping his chest to get his heart started again

"Cole. Hey, hey. Cole! Come on. Come on. Cole! Hey." Dean Says

"Hey! Hey! Okay! Hey. All right. Again." Cole Says

"No. No, we're done playing "Operation." I zap you again, you're toast. Just take a knee." Dean Says

IMPALA

Elena is driving the Impala, Sam is sitting in the passenger seat and his phone rings, he puts it on speakerphone.

"Dean. How did it go?" Sam Asks

"Worm was a no-show." Dean Says

"That doesn't make any sense. Last time.." Sam Says

"Well, this ain't the last time. I mean, maybe this is a whole new species, you know? All I know is that sparky struck out." Dean Says

"Well, there's got to be something. I mean, everything has a weakness, right?" Elena Says

"Well, what about you guys Any luck?" Dean Asks

"Were on my way to Kit's. Thought we'd check there first." Sam Says

"All right, well hurry up." Dean Says

"You got it." Elena Says As Sam hangs up

KITS CABIN

"You okay?" Dean Asks

"So this is what in over your head looks like." Cole Says

"Just got to keep your head in the game. Okay, what do we know about this thing?" Dean Says

"Uh, sucker dries you out. I'm thirsty already, man." Cole Says

"It likes water. Then when that's not enough..." Dean Says

"Blood. l don't know. Maybe lack of fluids makes the thing hostile." Cole Says

"So it's like a parasite. It wrings you dry, and then it moves on." Dean Says

"So if I dry myself out, the son of a bitch wouldn't like that very much, now, would he?" Cole Says

"No, he'd want the hell out. You'd be a hostile environment well, more than you already are." Dean Says

"Well, to be fair, you really haven't seen my chiller side." Cole Says

"What do you think about rapid dehydration?" Dean Asks

"Big fan. Just make sure you squash that sucker when it goes AWOL." Cole Says

"Sounds like a plan." Dean Says

"All right. Nothing like a sweat lodge in the woods, huh?" Dean Says while starting a fire
