Sam is sitting at the computer desk, staring at a page in his hand; Dean bustles around behind him, cleaning up.

"How do you erase this? Huh? Sam, come on, I need your help." Dean Says

"I killed him, Dean. I just broke in and killed him." Sam Says

"Listen to me. Whoever this guy is, he's a hunter. Which means that other hunters are going to come looking for his killer, which means we've got to cover our tracks, okay?" Dean Says

"His name was Steve Wandell. This is a letter from his daughter." Sam Says As Dean looks from Sam to the letter, then makes a decision. He grabs the CPU, lifts it above his head, and smashes it to the floor, stomping it with his boots for good measure. Dean looks at Sam, still sitting there despondent, tosses a rag to him.

"Wipe your prints, then we go." Dean Says

MOTEL-ROOM

Sam precedes Dean into the motel room.

"All right, we get a couple hours sleep and then we put this place in our rearview mirror. Look, I know this is bad, okay? You gotta snap out of it. Sam, say something!" Dean Says

"Just get some sleep and leave in the morning? Murder, Dean. That's what I did." Sam Says

"Maybe. Sam Scoffs, Okay? Hey, we don't know... shapeshifter!" Dean Says

"Oh, come on. You know it wasn't, you saw the tape. There was no eye flare, no distortion,

"Yeah, but it wasn't you! All right? I mean, yeah, it might have been you, but it wasn't you." Dean Says

"Well, I think it was. He sits down on the bed
I think maybe more than you know." Sam Says

"What the hell does that mean?" Dean Asks

"For the last few weeks I've been having ... I've been having these feelings." Sam Says The Dean walks to the bed to sit opposite of Sam.

"What feelings?" Dean Asks

"Rage. Hate. And I can't stop it. It just gets worse. Day by day, it gets worse." Sam Says

"You never told me this." Dean Says

"I didn't want to scare you." Sam Says As Dean nods, slaps his knee, stands up.

"Well, bang-up job on that." Dean Says

"Dean, the yellow-eyed demon, you know he has plans for me. And we both know that he's turned other children into killers before, too." Sam Says

"No one can control you but you." Dean Says

"It sure doesn't seem like that, Dean, it feels like no matter what I do, slowly but surely I'm, I'm just becoming..." Sam Says

"What?" Dean Asks

"Who I'm meant to be. I mean, you said it once yourself, Dean. I gotta face up to who I am." Sam Says

"I didn't mean this!" Dean Says

"But it's still true. You know that. Dad knew that too. That's why he told you, if it ever came to this . . ." Sam Says

"Shut up, Sam." Dean Says

"Dean, you promised him. You promised me." Sam Says

"No. Listen to me. We're gonna figure this out. Okay? I mean, there's gotta be a way, right?" Dean Says

"Yeah there is. He takes a handgun from his duffel, shoves it at Dean, I don't wanna hurt anyone else. I don't wanna hurt you." Sam Says As Dean looks down, at the gun Sam is handing him.
You won't.

"Whatever this is, you can fight it." Dean Says

"No. I can't. Not forever. Here, you gotta do it." Sam Says as he starts tearing up, They stare at each other for a long moment; then Sam grabs Dean's right hand and places the gun in it. Dean doesn't move, just stares as Sam in shock. Sam is shaky, upset.

"You know, I've tried to hard to keep you safe." Dean Says

He Nods, "I know." Sam Says Then Dean shakes his head no.

"I can't. I'd rather die." Dean Says As he drops the gun on the bed and shoulders past Sam.

"No. You'll live. He picks up the gun as Dean turns to face him, You'll live to regret this." Sam Says As He pistol-whips Dean, who falls to the floor unconscious.

An insistent knocking begins during the blackout. Dean awakens to realize that he is on the floor of the motel room; the motel manager, who has been knocking, opens the door.

"Hey. It's past your checkout." The Manager Says
As Dean gets up, very groggy

"What?" Dean Says

"It's past checkout, and I've got a couple here needs your room." The Manager Says

seeing an embarrassed businessman with a hooker
"Yeah, I'll bet they do. What time is it?" Dean Asks

"Twelve-thirty." The Manager Says

"That guy who was with me, have you seen him?" Dean Asks

"Yeah, he left before dawn in your car, and you should have gone with him, because now I'm gonna have to charge you extra." The Manager Says

"Oh, son of a..." Dean Says

"It's just policy, sir." The Manager Says

"I need to use your computer." Dean Says

"Now, why would I let you use my computer?" The Manager Says

The Manager is counting a stack of cash, as Dean talks on the phone behind him, in front of a desktop computer.

"Hi, uh, so sorry to bother you, but uh, my son snuck out of the house last night and, uh, went to a Justin Timberlake concert. What? Yeah. No, Justin is quite the triple threat. Uh, anyway, he's not back yet, and, and I'm just, I'm starting to worry. Right. Yeah, boys will be boys. But see, Sammy is uh uh uh, a diabetic, and uh, if he doesn't get his insulin, I just, I have to find him. Please, I'm begging you. Yeah, no no no, I"m on the website right now, I just need to activate the GDS in his cell phone. entering a password; his GPS screen shows the name Dean J.Mahogoof mobile phone number 785-555-2804, Yeah, right there. Duluth, Minnesota. Yeah, that is a long way to go for a concert. I appreciate your help." Dean Says

A BAR

Jo has her back to turned and is scrubbing the bar and saying goodnight to some customers.

"Good night, thank you." Jo Says Then Sam enters and clears his throat.

"Sorry, we're closing up." Jo Says

"How about just one for the road?" Sam Asks As She turns to face him

"Well, you're about the last person I'd expect to see." Jo Says

"Well, I guess I'm full of surprises. So can I get a beer?" Sam Asks

"Sure. One beer." Jo Says, She brings a bottle of beer over and sets it down on the bar firmly, then turns away, bustling over cleaning up the bar. So how'd you find me?"

"Well, uh, it's kind of what we do, you know?" Sam Says

"Speaking of 'we', where's Dean? and Elena?" Jo Asks

"Couldn't make it." Sam Says

"So what're you doing here Sam? I mean we didn't exactly part on the best of terms." Jo Says

"Right. Um, well, that's why I'm here. He Takes off his jacket. I kinda -- I wanted to see if we could square things, you know?" Sam Says As he takes off his jacket, Jo notices a circular burn mark with a short line through it on Sam's forearm.

"That looks like it hurts." Jo Says

"No. Nah, just, just had a run-in with a hot stove." Sam Says

"So you were saying something about squaring things?" Jo Says

"Yeah. Um ... Look, I know how you feel about my dad. And I can't say I blame you. He was obsessed -- consumed with hunting. And he didn't care who got caught in the cross-fire. And I guess that included your dad. But that was my father. That's not me." Sam Says

"What about Dean?" Jo Asks

Well, Dean's more like my father than I am, but h-- . . . She looks at him, then he laughs a little, Boy You're really carrying a torch for him, aren't you?
Jo scoffs, uncomfortably, I'll take that as a yes. It's too bad. Sam is smiling tightly. Cause see, Dean, he likes you, sure, but not in the way you'd want. I mean, maybe as kind of a . . . a little sister, you know? But -- romance, that's just out of the question, he -- He laughs again, he kind of thinks you're a schoolgirl, you know?, I'm not trying to hurt you, Jo, I -- I'm telling you 'cause I care." Sam Says

"That's real kind of you, Sam." Jo Says

"I mean it. he places a hand over hers on the bar,
I care about you a lot." Sam Says

"Sam, what's going on?" Jo Asks Then She tries to pull her hand away but he holds it, won't let go.

"I can be more to you, Jo." Sam Says

"Maybe you should leave." Jo Says

"Okay." Sam Says, He then shoves her hand away and stands to leave; she turns to face the bar, leaning on it heavily. Suddenly Sam reappears, grabbing her from behind and manhandling her.

"Sam, get off me! Sam! Get off me! Let go!" Jo Says
As She closes her right hand on a beer bottle, but before she can hit him with it he grabs her wrist and slams it onto the bar, shattering the bottle.

"Jo, Jo, Jo." Sam Says, He then shoves her around until she faces the bar and pins her there, left hand over her wrist, right hand stroking her hair.

"Sam, no! No! Please! Please!" Jo Screams, Then
He slams her forehead into the bar; she is knocked out, and he lifts her carefully to lie on the bar, stroking her hair in a disturbingly gentle manner.

"It didn't have to be this way. Maybe it did." Sam Says as He gives an evil grin.

A jukebox starts playing The Doors' "Crystal Ship". Nearby, Sam is tying Jo in a sitting position to a wide wooden post. She slowly wakes up.

"What the hell is going on? What are you doing?" Jo Asks

"So what exactly did your mom tell you about how your dad died?" Sam Says

"You're not Sam." Jo Says

"Don't be so sure about that. Answer the question." Sam Says, Jo says nothing Sam sighs heavily and goes around to the other side he sits in front of her, leaning in, his expression shifting to one of open concern. He pulls out a large knife and strokes her face with it. Come on. It's me. You can tell me anything, you know that. Answer. The question.

"Fine." Jo Says

"Fine." Sam Says

"Our dads were in California: Devil's Gate Reservoir. They were setting a trap for some kind of hellspawn. John was hiding, waiting, and my dad was bait." Jo Says

"That's just like John. Oh, I'll bet he dangled Bill like meat on a hook. Then what?" Sam Asks As He gets up and goes around to stand behind her.

"The thing showed up. John got too eager, jumped out too soon, got my dad exposed, out in the open. The thing turned around ... and killed him." Jo Says

"Hmm. Not quite." Sam Says

"What?" Jo Says

"What? Oh. See, it hurt him. It didn't kill him. You really don't know the truth, do you? I bet your mom doesn't either." Sam Says As He sits facing her again, leans in close.

"Know what?" Jo Asks

"You see, Bill ... was all clawed up. Was holding his insides in his hands. He was gurgling and ... praying to see you and Ellen one more time. So my dad ... killed him. Put him out of his misery like a sick dog." Sam Says as she begins crying

"You're lying." Jo Says

"I'm not. It's true. My daddy shot your daddy in the head . . ." Sam Says

"How could you know that?" Jo Asks

"I hear things." Sam Says As He stands and stabs the knife into the pillar, just above head level.

"Why are you doing this to me?" Jo Asks

"Like Daddy like daughter. You're bait. Open up.
he shoves a knotted rag in her mouth and ties it around her neck, That's a girl." Sam Says Then
The door bursts open and Dean enters with his gun out.

"Sam!" Dean Says As Sam grabs the knife from the pillar, his calm expression shifting to one of desperate panic, and places the knife at Jo's throat.

"I begged you to stop me, Dean." Sam Says

"Put the knife down, dammit." Dean Says

"I told you I can't fight it! My head feels like it's on fire, all right?! Dean. Kill me, or I'm going to kill her. Please. You'd be doing me a favor! Shoot me.
He turns to face Dean arms are spread, Shoot me!" Sam Says As Dean stares with his gun steady, looks at Job out of the corner of his eye

"No, Sammy, come on."Dean Says as he turns away, lowering the gun.

"What the hell's wrong with you, Dean? Are you that scared of being alone that you'd rather let Jo die?" Sam Says Then Dean turns suddenly, flinging water from a flask at Sam the water hisses and steams as it strikes him.

"That's holy water, you demonic son of a bitch!" Dean Says Then Sam raises his head, his eyes are the solid black of a demon's. Dean flings more holy water at him, Sam growls, turns and runs, bursting through a window and fleeing. Dean takes the knife and cuts Jo Free she pulls the gag out of her mouth as Dean runs towards the shattered window.

"He was possessed?!, Dean turns and stares at her for a moment, then leaps through the window,Dean!" Jo Says

Dean and Possessed-Sam stalk each other through a dim, crowded warehouse, each with a handgun. During the following they never see each other directly, instead hiding stealthily behind piles and boxes and shouting at each other.

"So who are you?" Dean Asks

"I got lots of names." Sam Says

"You've been in Sam since he disappeared, haven't you?" Dean Asks

"You shoulda seen your face when you thought he murdered that guy. Pathetic." Sam Says

"Why didn't you kill me? You had a dozen chances." Dean Says

"Nah, that would have been too easy. Where's the fun in that? You see, this was a test. Wanted to see if I could push you far enough to waste Sam. Should've known you wouldn't have the sack. Anyway. Fun's over now." Sam Says

"Well, I hope you got your kicks. 'Cause you're gonna pay hell for this, I'm gonna make sure of that." Dean Says

"How? You can't hurt me. Not without hurting your little brother. Dean is putting his gun away, pulling out the flask of holy water. See, I think you're gonna die, Dean. You and every other hunter I can find. One look at Sam's dewey, sensitive eyes? They'll let me right in their door." Sam Says As He gets up, heading outside; Dean follows. They are on an open-air dock. Once Dean is out in the open, looking around at the water, Sam steps out, takes aim, and shoots Dean, hitting him in the shoulder. Dean is knocked into the water with a splash; Sam stalks to the edge and peers over where Dean fell; not seeing Dean in the water, he smiles.
