In Madison's Apartment, She joins Sam in the living room, while he watches the full moon from the window.

"So, um ... I'm gonna turn in." Madison Says

"Okay, yeah. Well, I'll be here." Sam Says

"Okay" Sam Says

"You know, if you hear anything, I mean if you wake up, just – just call out." Sam Says As He fidgets awkwardly

"Okay." Madison Says

"Okay." Sam Says, She smiles uncomfortably and goes into her bedroom. Sam sighs, frustrated with himself.

Later, Sam is watching TV a 1957 Western movie in the living room. He glances at Madison's bedroom, but there's no movement.

Meanwhile, Dean and Elena are standing on the street outside Kurt's house. They see a light turn on inside the house and gets their guns ready. Suddenly, Elena hears glass shattering. She looks back up to see the lights off in the house.

"What the—?" Dean Says, They runs to the house and bursts through the door. Entering one of the rooms, They sees a woman hovering over Kurt's mauled body. She turns towards Dean and Elena . It's Madison, and she's a werewolf. Though she still looks human, her eyes have turned an electric blue, her teeth have turned to bloody fangs, and she has long claws. She growls and runs at Dean and Elena , pushing them into the wall. Dean cuts her arm with his knife – she growls in pain, and runs out the open window.

"Oww" Elena Says as she groans in pain

"You Okay?" Dean Asks

"Yeah, I Think So" Elena Says

"Come On" Dean says as he helps up Elena and they leave the apartment

It's Morning. Sam is still at Madison's apartment, awake, and getting a glass of water. He answers his ringing cell phone.

"Dean, you okay?" Sam Asks

"Yeah, now that I'm conscious. The werewolf knocked me out. Sam, it's Madison." Dean Says

"What?" Sam Says

"Yeah, awesome job of keeping an eye on her." Elena Says

Sam enters Madison's bedroom to see that she is sound asleep, apparently naked, in bed.

"Guys, I've been here the whole time. She's in bed, asleep." Sam Says

"Well, she wasn't an hour ago. Check her right arm below her elbow. I nicked her with a silver knife." Dean Says As He hangs up. Madison rolls over and wakes up, noticing Sam

"Morning." Madison Says, She sits up and he notices that she is naked, covered only by her bed sheets. and sees the wound on her arm.Um... where are my pajamas? , Sam's upset and leaves the bedroom. Sam? What's going on? Where are you going?, She jumps out of bed, wrapping the comforter around her, and follows him to the living room, where he is locking the front door.

"I'm not going anywhere. And neither are you." Sam Says

Later, Madison is seated in a chair, with her wrists bound. Sam is standing in front of her, holding a gun.

" You're psychotic. The whole "I'm a cop" trip – God, I am so stupid." Madison Says

"Well, I guess neither of us are who we said we were, huh?" Sam Says

"Sam, you're sick, okay? You're imagining things. Monsters don't exist, not really." Madison Says

"You know what? Save the act." Sam Says

"It's not an act! I am not a werewolf! There's no such thing! It's made up, all right? Th– They're not real! You know they're not real!" Madison Says

"No?!, he points to her wound,Then where did that come from?" Sam Asks

" I don't know! Sam, God, you need help. Please, don't do something that you're gonna regret. I'm not what you think I am. I'm not." Madison Says As Sam is visibly upset, hears knocking at the door. He opens it to see Dean and Elena , who enters and Dean smirks at Madison.

"How you doin'? My head feels great, thanks." Dean Says

"We've gotta talk. He brings Dean and Elena into another room. She says she has no idea what I'm talking about." Sam Says

"She's lying." Elena Says

"Or maybe she really doesn't know she's changing, you know? Maybe – maybe when the creature takes over, she blacks out." Sam Says

"Like a really hot Incredible Hulk. Come on, dude, she ganked her boss and her ex-boyfriend. That doesn't sound rash and unconscious." Dean Says

"Yeah, but what if it was, Dean? I mean, what if some animal part of her brain saw both those guys as threats? Hell, the cop, too." Sam Says

"What are you, the Dog Whisperer now?" Elena Says

"Look, I just... I don't know, there, there, there was something in her eyes." Sam Says

"Yeah, she's killing people!" Dean Says

"But if she has no control over it—" Sam Says

"Exactly. She can't control it. Even if she's telling the truth, it's not gonna change anything." Elena Says

"I'm not putting a bullet through some girl's chest who has no idea what's happening." Sam Says

"Sam, she's a monster, and you're feeling sorry for her?" Dean Asks

"Maybe I understand her. Look, there might be another way we can get the job done without having to waste her." Sam Says

"Are you thinking what I think you're thinking?" Dean Asks

"Dad's theory – "lycanthropy might have a cure if you kill the werewolf who bit you, severing the bloodline".Sam Says as he flips through John's Journal

"Might have a cure. Meaning "who the hell knows?" Dean Says

"It's worth a shot." Sam Says

"We don't even know where to start looking, all right? I mean, the puppy that bit her could be anyone, anywhere. It could've been years ago." Dean Says

"No. I don't think so." Sam Says As He leads Them back to the living room, where Madison is still seated.

"Madison, when were you mugged?, She doesn't want to answer, she just looks at him.Please. It's important, all right? Just answer the question." Sam Says

"About a month ago." Madison Says

"Did you see the guy?" Elena Asks

"No. He grabbed me from behind." Madison Says

"Did he bite you?" Sam Asks

"How did you know that?" Madison Asks

"Where?" Sam Asks

"On, on the back of my neck." Madison Says As Sam shows her that he is setting his gun down, and goes behind her, gently brushing her hair away and exposing a scarred lump the size of a golf ball on her neck.

"Oh, that's just a love bite. Believe me, that could have been a lot worse. Where were you at the time?" Dean Asks

"Walking home from a friend's loft." Madison Says

"Let me guess. Not too far from Hunter's Point?" Sam Asks and She nods.

Sam, Elena and Dean are back in the other room; Sam closes the door and turns to face them.

"The same place where those other murders happened. I'm telling you, it's a werewolf's hunting grounds." Sam Says

"Maybe, but that doesn't mean it's gonna be out there tonight." Elena Says

"It's the right time of the lunar cycle. Look, I know it's a long shot." Sam Says

"Hey, you're forgetting something. Maddie's probably gonna turn soon, all right? We can't just let her take off to an all-you-can-eat buffet." Dean Says

"I'll stay with her." Sam Says

"And if she busts loose?...Sam?" Dean Says

"I'll do it." Sam Says

"Sam." Elena Says

"I'll shoot her, all right? But Dean and Elena I need you two to go out there. At least go look for the thing. Dean, please. We can save this girl." Sam Says

"Fine." Dean Says As Sam Nods, They leave the apartment. Sam rejoins Madison, who is still crying.

"Please. Just let me go." Madison Says As Sam looks at her sympathetically and pulls up a chair to sit in front of her.

"Look ... I know you're scared. I also know that there's no way in hell you're gonna believe me. But I'm doing this because I'm trying to help you. I'm not gonna lie, all right, the odds aren't exactly in our favor. But if this goes the way I pray it does ... I'll untie you, and I'll walk out that door, and I'll never come back. You'll live the rest of your life. And I'll just be a bad memory." Sam Says he starts to get emotional, tearful, as is Madison

__________________________________

At Hunters Point, A woman, clearly a hooker, is walking the dark street alone. She stops when she hears an animal howling, and looks nervous.

In Madison's Apartment, Sam Is watching the full moon while Madison sits in the chair. Suddenly, her fingernails grow, stretching into claws. Her eyes turn bright blue and she bares her fangs. Sam turns just as she breaks loose from the chair. She knocks him to the ground, but he quickly gets up, aiming his gun.

The hooker is running down the street when suddenly, she comes face-to-face with the animal.

Sam keeps his gun aimed at Madison. Just as she lunges at him, he moves out of the way, forcing her into her bedroom. He moves the entertainment center in front of the door, trapping her inside.

The werewolf catches up with the hooker, dragging her screaming across the pavement.

"Hey!" Dean Says As The werewolf looks up just as Dean and Elena shoots him, serval times in the chest. The werewolf is Madison's neighbor, Glen. The woman stands up, frightened, and glances at Dean and Elena before running away.

"Hey, don't mention it!" Dean Says, He and Elena crouches next to Glen, who is coughing and choking. His mouth is covered in blood. After a moment, his fangs retract, and he returns to normal

"It happened ... again. Where am I? H–help me. Oh, God. Oh my God." Glen Says

"All right, easy, Glen. Just take it easy." Elena Says as they watch as Glen dies, his eyes glazing over.

In The Morning Madison wakes up as Sam opens the bedroom door.

"It should be over now. You'll never see me again." Sam Says, She Stan's Up and surveys the bedroom. Furniture is overturned, and there are claw marks covering every inch of the walls. When she turns around, Sam is gone.

The boys and Elena are parked outside Madison building.

" It was sort of sad, actually. Glen had no clue what was going on. Hey, why do you think he turned Madison instead of just killing her in the first place?" Dean Asks

"I don't know. I mean, he kind of seemed to have a thing for her." Sam Says

"Maybe his primal instinct did, too. Maybe he was looking for a little, uh, hot breeding action."  Dean Says

"Really" Elena Says

"Yeah. Something like that." Sam Says

"So?" Dean says

"So what?" Sam Asks

"Speaking of Madison ...?" Dean Asks

"Oh, whatever." Sam Says

"Don't "whatever" me, man, you liked her. Maybe, uh—" Dean says

"Dean, she thought I was a stark-raving lunatic." Sam Says

"You saved her life." Elena Says

"Yeah, but she doesn't know that." Sam Says as Madison appears at the window

"You know, for a stake-out, your car's a bit conspicuous. What are you still doing here?" Madison Says

"Honestly? Uh, we're pretty sure you're not gonna turn tonight, but we've gotta be a hundred percent, so... you know, we're ... lurking." Elena Says

"I know this sounds crazy." Sam Says

"Sure does. Well, if we're gonna wait it out... we might as well do it together." Madison Says

MADISON APARTMENT

She lets them inside

"You were telling the truth, weren't you? About everything. What you did – it was to help me." Madison Says

"Yeah." Sam says

" I did all of those horrible things ... when I turned." Madison Says

"You didn't know." Sam Says

"So, when will we know for sure? Moonrise?" Madison Asks

"No, I don't think so. You turned middle of the night last night. I think we've gotta hang in until sun-up." Sam Says

"Well, it looks like we've got ourselves a few hours to kill. Poker, anyone?" Dean Asks

Later, the Four of them watch as the sun sinks and the moon rises. Dean lays his gun on the table where Elena has her head down, Sam and Madison watch them from the couch.

"Oh, no, you guys talk." Dean Says

A few hours later, they watch from the window as the sun comes up.

"Does – does this mean it worked?" Madison Asks

"Yeah. I think so." Sam Says

"Oh, God, thank you. Thank you so much. She gives Sam a hug. Dean and Elena clears their throats, and they pull away. She laughs You, too, Dean and Elena Thank you.

"Aw, don't mention it. So, me and Elena are gonna head back to the hotel and ... watch some Pay-Per-View, or something." Dean Says

"We Are" Elena Says

"Yes" Dean says as he leads her to the door, They leaves the apartment, Dean pumping his fist in the air as he leaves.

"That was smooth, heh." Madison Says

"He means well, but..." Sam Says

"You mean, he thinks you're gonna get laid." Madison Says

"Look, I—" Sam Says

"It's okay." Madison Says

"No. I know I scared the crap out of you, all right? I–I mean, I tied you to a chair." Sam Says

"That's right up there with me scratching up your face." Madison Says

"There's just no way ... we could go back, you know? Before it happened." Sam Says

"You're right. There's just no way." Madison Says

Sam shakes his head. Then, after a moment, Madison gives in and kisses him. Sam immediately responds, pushing her against the wall. They strip each other of their clothing and make their way to the bedroom, falling back onto the bed. Throughout the night, they continue to make passionate love, letting go of all they had been holding back. Hours later, they fall asleep in each other's arms, completely content.

The Full Moon Rises

Sam wakes up and looks around. He hears a growl and turns to see Madison, who has returned to her werewolf form, eyes blue and fangs bared. Before Sam can catch her, she jumps out the window, leaving him stunned.

At The Motel, Sam runs down the hall to Dean's room, pounding on the door. Dean Answers

"She – she turned." Sam Says

"What?" Dean Says

"I couldn't grab her in time." Sam Says

"We'll find her, Sammy." Dean Says

"What Happened" Elena Asks

"Madison Turned Now we gotta go now" Sam Says

"Okay Let Me Change then I-" Elena Says

"No Let's Go Lena Now!" Sam Says

"Okay Then" Elena Says

Sam, Elena and Dean are quickly coming down the steps of the China Sea Motel

"I already called Dad. He doesn't know anything. Except he knew severing the bloodline wouldn't work. That's everyone. They all say it's impossible to reverse it." Elena Says

"How come she didn't turn when we were with her?" Dean Says

"Dean—" Sam Says

"So, what, you put her to bed and then she wolfed out? Maybe she's gotta be asleep to turn." Dean Says

"What the hell does it matter, Dean? Look, we've gotta find some way to help her, some legend we missed or something." Sam Says

"If there was, don't you think someone we know would've known it?" Dean Says

"Well, then we have to look harder! Until we find something." Sam Says

"Sammy, I don't think we've got a choice here anymore." Elena Says

"What?" Sam Says

"I hate to say it Elena's right look She's a sweet girl, but part of her is—" Dean Says

"Evil?"

"Yeah." Dean Says

"Yeah, that's what they say about me, Dean! So me you won't kill, but her you're just gonna blow away?" Sam Says As His phone rings,He answers it

"Sam?" Madison Says

"Madison, where are you?" Sam Asks

"I don't – I don't – I don't know where I am." Madison Says

"Well, do you see any street signs?" Sam Asks

"Um ... yeah, yeah, Middle Point." Madison Says

"All right, hold on, Maddie. We're coming to get you, just stay where you are." Sam Says

MADISON'S APARTMENT

The Four of them are in the living room. The gun is sitting on the table.

"I don't remember anything. I probably killed someone last night. Didn't I?" Madison Says

"There's no way to know yet." Dean Says

"Is there something else we can try to make it go away?" Madison Asks

"We'll find something. I mean, there's gotta be some answer, somewhere." Sam Says

"That's not entirely true. Madison, you deserve to know. We've scoured every source. There's just no cure." Elena Says

"Is – is he right?" Madison Asks As Sam begins Choking up, He stands and turns away.

"Well, we could lock you up at night, but ... you bust out, and some night you will, someone else dies. I'm sorry. I am." Dean Says

"So, I guess that's all there is to it, then." Madison Says

"Stop it. Don't talk like that." Sam Says

"Sam, I don't wanna hurt anyone else. I don't wanna hurt you." Madison Says As She picks up the gun and brings it to him

"Put that down." Sam Says

"I can't do it myself. I need you to help me." Madison Says

"Madison, no." Sam Says

"Sam... I'm a monster." Madison Says

"You don't have to be. We could find a way, all right? I can. I'm gonna save you." Sam Says as she begins to cry

"You tried. I know you tried. But this is all there is left. Help me, Sam. I want you to do it. I want it to be you." Madison Says

"I can't." Sam Says

"I don't wanna die. I don't. But I can't live like this. This is the way you can save me. Please. I'm asking you to save me." Madison Says As Sam shakes his head. Dean walks over to them and carefully takes the gun from Madison. Sam walks to another room.

Sam is holding back tears as Dean and Elena enters silently.

"Sam. He Holds up the gun, I'm sorry." Dean Says

"No, you're right. She's right." Sam Says

"Sammy, I got this one. I'll do it." Dean Says

"Dean-" Elena Says

"She asked me to." Sam Says

"You don't have to." Dean Says

Tears are sliding out his eyes, "Yes, I do. Please, He holds his hand out for the gun, tears streaming down his face. Dean hands it to him.Just wait here." Sam Says

He glances back at Dean and Elena shaking, tears streaming, before heading back to the living room. Dean now alone with Elena lets a tear roll down his cheek. He flinches as he hears a single gunshot from the next room.
