( SWAN SONG )

      "On April 21, 1967, the 100 millionth GM vehicle rolled off the line at the plant in Janesville—a blue two-door Caprice. There was a big ceremony, speeches. The lieutenant governor even showed up. Three days later, another car rolled off that Same line. No one gave two craps about her. But they should have, because this 1967 Chevrolet Impala would turn out to be the most important car—no, the most important object—in pretty much the whole universe."

      "She was first owned by Sal Moriarty, an alcoholic with two ex-wives and three blocked arteries. On weekends, he'd drive around giving Bibles to the poor "gettin' folks right for Judgment Day." That's what he said. Sam and Dean don't know any of this, but if they did, I bet they'd smile. After Sal died, she ended up at Rainbow Motors, a used-car lot in Lawrence, where a young marine bought her on impulse. That is, after a little advice from a friend. I guess that's where this story begins. And here's where it ends."

      "Hey." Sam says as Dean takes a beer out of a cooler and leans against the Impala. "Dean? What's going on?"

      "I'm in." Dean says.

       "In with...?" Sam asks.

      "The whole "up with Satan" thing. I'm on board." Dean says.

      "You're gonna let me say yes?"

      "No. That's the thing. It's not on me to let you do anything. You're a grown—well, overgrown—man. If this is what you want, I'll back your play."

      "That's the last thing I thought you'd ever say." Sam says.

       "Might be. I'm not gonna lie to you, though. It goes against every fiber I got." Dean says. "I mean, truth is... You know, watching out for you... it's kinda been my job, you know? But more than that, it's... it's kinda who I am. You're not a kid anymore, Sam, and I can't keep treating you like one. Maybe I got to grow up a little, too. I don't know if we got a snowball's chance. But... But I do know that if anybody can do it... it's you."

      "Thank you." Sam says.

       "If this is what you want... Is this really what you want?" Dean asks.

      "I let him out. I got to put him back in." Sam says.

      "Okay. That's it, then."

BUILDING
[ ☼ ]

      Bodies hang upside down over a devil's trap. Sam wipes blood off a large knife. Castiel puts the lid on a jug of blood. Dean stands nearby. Sam, Castiel and Dean exit the building.

      "I still don't understand why you have to do this." Elena says to Sam.

      "It's my fault that this is happening." Sam says. "And if it means keeping you safe, then so be it." Sam, Elena and Castiel carry gallon jugs of blood and put them in the trunk of the Impala.

       Dean walks over to Bobby. "I still can't get used to you at eye level." He says.

      "So, was I right?" Bobby asks.

       "As always, Yoda. Two stunt demons inside, just like you said."

       "Did you get it?" Asks Bobby.

       "Yeah, all the "go juice" Sammy can drink." Dean says.

       "You okay?"

       "Not really." Dean says. "What do you got?"

       "Not much. These look like omens to you?" Bobby hands Dean a newspaper. "Cyclone in Florida, temperature drop in Detroit, wildfires in L.A."

       "Wait. What about Detroit?" Dean asks.

       "Temp's dropped about 20 degrees, but only in a five-block radius of downtown Motown." Bobby says.

       "That's the one. Devil's in Detroit."

       "Really? As far as foreboding goes, it's a little light in the loafers. You sure?" Asks Bobby.

      "Yeah, I'm sure."

IMPALA
[ ☾]

       Dean is driving, Sam riding shotgun. Castiel and Elena are asleep in the back seat. "Aw. Ain't he a little angel?" Dean asks.

      "Angels don't sleep." Sam says.

      "Sam, I got a bad feeling about this." Dean says.

      "Well, you'd be nuts to have a good feeling about it." Sam says.

      "You know what I mean. Detroit." Dean says. He always said he'd jump Sam's bones in Detroit. Here we are."

      "Here we are." Sam says.

      "Maybe this is him rolling out the red carpet, you know?" Dean asks. "Maybe he knows something that we don't."

       "Dean, I'm sure he knows a buttload we don't. We just got to hope he doesn't know about the rings." Sam says. "Hey, um... on the subject, there's something I got to talk to you about."

       "What?" Dean asks.

       "This thing goes our way and I...Triple Lindy into that box... y-you know I'm not coming back." Sam says.

       "Yeah, I'm aware."

       "So you got to promise me something." Sam says.

       "Okay. Yeah. Anything." Dean says.

       "You got to promise not to try to bring me back." Sam says. "And I know you'll watch out for Elena."

       "What? No, I didn't sign up for that." Dean says. "I mean, Elena yeah, but not saving you? You know I can't do that."

       "Dean—" Sam starts.

       "Your Hell is gonna make my tour look like Graceland." Dean says. "You want me just to sit by and do nothing?"

       "Once the Cage is shut, you can't go poking at it, Dean. It's too risky." Sam says.

       "No, no, no, no, no. As if I'm just gonna let you rot in there."

       "Yeah, you are. You don't have a choice." Sam says.

       "You can't ask me to do this." Dean says.

       "I'm sorry, Dean. You have to."

       "So then what am I supposed to do?" Asks Dean.

       "You go find Lisa. You pray to god she's dumb enough to take you in, and you—you have barbecues and go to football games. You go live some normal, apple-pie life, Dean. Promise me."

ALLEYWAY
[ ☾]

      Bobby looks through binoculars at a building in which a man is standing in the window. He walks over to Sam, Dean, Elena and Castiel. "Demons. At least two dozen of them. You were right—something's up." He says.

       "More than something. He's here. I know it." Dean walks to the trunk of the Impala. Sam looks at Bobby.

       "I'll see ya around, kid." Bobby says.

       "See ya around." Sam and Bobby hug.

       "He gets in... You fight him tooth and nail, you understand? Keep swingin'. Don't give an inch." Bobby says.

       "Yes, sir." Sam holds out his hand to Castiel. "Take care of these guys, okay?"

       "That's not possible."

       "Then humor me." Sam says.

       "Oh. I was supposed to lie. Uh... Sure. They'll be fine." Castiel says.

       "Just—just stop... talking." Dean says.

       "You mind not watching this?" Sam asks and Dean walks away. Sam picks up a jug.

       Sam clears his throat and closes the trunk. Dean is leaning on the side of the car. Sam takes a deep breath. "Okay. Let's go." Sam walks past Dean and after a moment Dean follows him. Bobby, Elena and Castiel watch them go.

       Sam raises his arms as he approaches the building with the Demons. "All right! We're here, you sons of bitches! Come and get it!" He yells. Two demons come outside.

      "Hey, guys. Is your father home?" Dean asks.

BUILDING
[ ☾]

       The demons manhandle Sam and Dean inside. "Hey, guys. So nice of you to drop in." Lucifer says.

       "The Impala, of course, has all the things other cars have... and a few things they don't. But none of that stuff's important. This is the stuff that's important. The army man that Sam crammed in the ashtray—it's still stuck there. The Legos that Dean shoved into the vents—to this day, heat comes on and they can hear 'em rattle. These are the things that make the car theirs—really theirs. Even when Dean rebuilt her from the ground up, he made sure all these little things stayed, 'cause it's the blemishes that make her beautiful. The Devil doesn't know or care what kind of car the boys drive."

BUILDING
[ ☾]

       Lucifer breaths on the window pane and draws a pitchfork in the condensation. "Sorry if it's a bit chilly. Most people think I burn hot. It's actually quite the opposite." He says.

      "Well, I'll alert the media." Dean says.

       Lucifer's face is covered with red sores. "Help me understand something, guys. I mean, stomping through my front door is... a tad suicidal, don't you think?" He asks.

      "We're not here to fight you." Sam says.

       "No? Then why are you?" Asks Lucifer.

       "I want to say "yes." Sam says.

       "Excuse me?" Lucifer asks as Sam takes a breath, closes his eyes and the two demons drop dead in flashes of light. "Chock-full of Ovaltine, are we?"

       "You heard me. Yes." Sam says.

       "You're serious."

      "Look, Judgment Day's a runaway train. We get it now. We just want off." Says Sam.

       "Meaning?" Lucifer asks.

       "Deal of the century. I give you a free ride, but when it's all over, I live, he lives, you bring our parents back—" Sam starts.

       "Okay, can we please drop the telenovela?" Lucifer asks. "I know you have the rings, Sam."

      "I have no idea what you're talking about." Sam says.

      "The Horsemen's rings? The magic keys to my Cage? Ring a bell? Come on, Sam. I've never lied to you. You could at least pay me the Same respect. It's okay. I'm not mad. A wrestling match inside your noggin... I like the idea." Lucifer says. "Just you and me, one round, no tricks. You win, you jump in the hole. I win... Well, then I win. What do you say, Sam? A fiddle of gold against your soul says I'm better than you."

      "So he knows. Doesn't change anything." Sam says.

      "Sam." Dean says.

      "We don't have any other choice."

      "No." Dean says.

      "Yes." Sam says as Lucifer closes his eyes and bright light emanates from him.

       Bobby, Elena and Castiel watch as the windows of the building blaze with light, then dim. Elena pushes away from them and runs inside.

      Dean looks around. Sam is motionless on the floor. Dean takes the Horsemen's rings out of his pocket and throws them at the wall, where they stick. "Bvtmon...Tabges...Babalon."
