Dean is kneeling at a safe, from which he pulls out the Colt. A man, Daniel Elkins, appears with a shotgun pointed at Dean's back. "Hold it right there, friend. Drop the gun, be on your way." Daniel threatens. Dean pretends to lay the Colt on the top of the safe, but instead points it at Daniel. "Can't do it, Daniel." Dean said.

"Who the hell are you?" Daniel asked him. "A hunter, just like yourself." Dean tells him. "Thief's more like it." Daniel growls. "I just need it for a few days." Dean said to him. "Not happening, mister." said Daniel. "Look, I have a chance to save my family's lives. My family. But I need this gun to do it. So if you want to stop me? Kill me." Dean said and he lowers the Colt and walks slowly toward the door past Daniel.

Then he turns to look at Daniel, who begins to lower his gun. "There's some hunters in Lawrence, the Campbells." Dean said. "Never heard of them." Daniel said. "That's where she'll be." Dean said and he begins to leave.

Meanwhile, at the Campbell house, Mary and Samuel are sitting at the dining room table cleaning guns when Mary turns to her dad. "Dean say where he was going?" she asked. "Said he was gonna kill a demon." Samuel replied and Mary chuckles. "Kill a demon? That's impossible." She said. "Yep." He dad mutters.

"Where?" She asked. "Uh...oh, I don' know, over in Haleyville, uh, Walsh's maybe." He said, shrugging, and Mary looks up at him. "Wait, not Liddy Walsh?" She asked, worried. "Well, yeah, I- I- I think so." He stutters. "Dad, she's a friend of mine! We gotta help her." She exclaims as Deanna walks to the door of the room, and sees Mary getting up.

"What's wrong?" she asked. "I'll be in the car." Mary replied as she walks off. "Hey –" Deanna said but Samuel speaks up. "I mean, she wants to hunt, she doesn't want to hunt, is this some female time of month thing?" He asked and Deanna sighs and walks back into the other room. "What?" He asked, wondering what he said wrong.

At the Walsh house, Liddy is sitting on the sofa with Dr.Brown as he looks her over. "I'm sorry, Liddy, it's metastasized." He said to her. "Where?" Liddy asked. "His liver, his lungs. It's time we talked about arrangements." said Dr Brown. "No, you have to do something, Dr. Brown." She pleads and he looks at her.

"There is one way, a cure actually, but I'll need your help." he said. "What do I have to do?" she asked. "Nothing. Just in ten years, I'm going to come to you and ask for something then." he said. "What?" she asked him. "Nothing you'll miss." Dr. Brown says as his eyes turn yellow.

The door bursts open and Samuel enters then shoots Brown in the chest while Liddy screams. Brown's eyes open and Samuel cocks the shotgun again. Brown waves his hand and Samuel's shotgun flies across the room. Then Bornw waves his other hand and Samuel flies backwards and gets pinned to the wall behind him.

"Oh, God." Liddy exclaims. "Hold that thought." Brown said and he approaches Samuel. "You son of a bich." Samuel said. Brown leans in to Samuel, but turns around abruptly. Mary is standing behind him with a raised knife. He grabs Mary by the throat.

"Hello there." he greets as Mary slices him with the knife. "Where the hell have they been hiding you?" Brown asked as Mary keeps attacking. Brown grabs her arm and she drops the knife then she punches him. "I like you. You got a lot of spunk." Brown said and Mary kicks him. He grabs her leg, then slams her against a wall.

"Mary!" Samuel shouts and Dean bursts in with the Colt drawn. Brown pulls Mary in front of him as a shield. "Let her go!" Dean yells while Brown looks at Dean, shocked.

"Where'd you get that gun?" he asked and Dean cocks the Colt and nods to Mary, who breaks away from Brown. Black smoke pours from Brown's mouth and goes out a vent in the wall. "Damn..." Dean growls.

"Mary, what else did he say to you?" Dean asked Mary as they stand out on Liddy's yard. "I told you, just that he liked me." Mary said then she looks up at Dean with fear in her eyes. "What did he mean by that?" She asked, fearfully, as Samuel joins them on the lawn.

"Liddy's a strong kid, she'll be fine." Samuel said then he looks at Mary. "Are you okay?" He asked her. "No, Dad, I'm pretty far from okay. Can we go?" Mary said as she turns and walks to the truck. Samuel turns to Dean.

"Nice job in there." he said. "I missed the shot." Dean grumbles. "Take the compliment, son. I'm saying that I was wrong about you." Samuel said and Dean looks at him, then to the truck where Mary went, and looks back at Samuel, obviously upset. "We need to talk alone." He said.

"We have to kill this thing now, or Mary dies." Dean said after they make it to Campbell's house. "What? How do you know that?" Samuel asked and Dean pulls out John's journal. "I just do, okay?" He said.

"When?" Samuel asked. "I don't know, maybe today, probably years from now, but it's happening, trust me." Dean assures. "So what, are you some kind of a psychic now too?" Samuel asked. "No. Alright, listen to me." Dean said and he goes to the table and sits down next to Samuel.

"Now, this is gonna sound a little...actually it's gonna sound massively, massively crazy." Dean said. "Okay." Samuel said, unsure. "Mary is my mother." Dean said. "Excuse me?" Samuel asked.

"And I am your grandson, and I know what the hell I'm talking about." Dean said while Samuel looks at him in disbelief. "You wanna run that by me again, son?" He asked. "My real name is Dean Winchester. I was born January 24th, 1979. My parents are Mary and John Winchester." Dean admits while Samuel gives him a funny look.

"I don't have to listen to this." he grumbles as he starts to get up. "Mary gets killed by a yellow eyed demon in 1983, and I think that this – what happened tonight – I think this is the moment that he caught her scent. Now, if we don't catch this thing now, and kill it, and it gets away? Then Mary dies. So I am asking you, please." Dean pleads to him.

Meanwhile, Mary runs up to John and throws herself into his arms. "Hey, you – you okay?" John asked her, worried. "You promised you'd take me away." She said, questioning. "Of course I did." John said. "Do it now." Mary said and John opens the door of his car. Mary climbs in, and he shuts it after her, looking concerned.

"How did I know about the Colt? Huh? How did I know about the Yellow Eyed Demon? Or where it would be? I'm not making this up, Samuel." Dean said as Samuel still looks at him. "Every bone in my body is aching to put you six feet under, but there's something about you – I can't shake it. Now, I may be crazier than you, son, but I believe you." Samuel said and Dean sighs with relief. "Thank you." He said.

"I mean, how do we find this bastard?" Samuel asked him. "Right here, the list." Dean said as he opens John's journal. "And with the Colt?" Samuel asked. Dean pulls the Colt out of his jacket and puts it on the table. "Yeah." Dean said. "Here, let me see it." Samuel asked.

Dean hesitates and then moves it further away from Samuel. "Sorry, I don't let anybody hold it." Dean said. "I'm your grandfather." Samuel said. "Nothing personal." Dean tells him. "Sure it is, especially when it's me you're trying to kill." Samuel said and his eyes turn yellow. He raises his hand and the chair that Dean is sitting slams against the wall. Dean glares, but appears unable to move.

"Future boy, huh?" The Demon said as hewalks over to Dean. "I only know one thing that's got the juice to swing something like that. You must have friends in high places. So, I kill your Mommy? That's why you came all this way? To see little old me?" He asked. "Oh, I came here to kill you." Dean growls. 

"Hey, wait a minute, if that slut Mary's your Mommy, are you...are you one of my psychic kids?" The demon asked and he leans in and sniffs Dean. "No, not you. Maybe you got a sis, or a bro. That's terrific, means it all worked out. After all, it's why I'm here." He said, smiling.

"So that's what this is about, these deals you're making. You don't want these people's souls." Dean said. "No, I just want their children. I'm here to choose the perfect parents, like your Mommy." The demon said. "Why her? Why any of them?" Dean asked. "Because they're strong." The demon said as Deanna peeks around the corner of the kitchen doorway and sees what is happening.

"They're pure, and they eat their Wheaties. My own little master race – they're ideal breeders." the demon said and Dean furrows his brow. "Oh, get your mind out of the gutter. No one's breeding with me. Though, Mary? Man, I'd like to make an exception. So far, she's my favorite." the demon said and Dean looks furious and tries to move, but can't.

Deanna watches from the next room. "So why make the deals?" Dean asked him. "I need permission." the demon said as Deanna comes quietly into the room. "I need to be invited, into their houses, I know, I know, the – the red tape'll drive you nuts, but in ten short years, it'll all be worth it. ‘Cause you know what I'm gonna do to your sibling? I'm gonna stand over their crib and I'm gonna bleed into their mouth. Demon blood is better than Ovaltine, vitamins, minerals – it makes you big and strong." The demon explains.

"For what? So they can lead your discount demon army? Is that your big plan?" Dean asked.  Please, my end game's a hell of a lot bigger than that kid." The demon scoffs. "End game? What end game?" Dean asked, confused. "Like I'm gonna tell you, or those angels sitting on your shoulder. No, I'm gonna cover my tracks good." The demon said.

"You can cover whatever the hell you want, but I'm still gonna kill you." Dean spat. "Right. Now that, I'd like to see." the demon laughs. "Maybe not today, but you look into my eyes, you son of a bitch, ‘cause I'm the one that kills you." Dean growls.

"So, you're gonna save everybody, is that right? Is that it? Well, I'll tell you one person that you're not gonna save." The demon takes out a knife. "Your Grandpappy." The demon said and he winks and plunges the knife into Samuel.

"No!" Dean and Deanna say at the same time. Then the demon  goes for Deanna, while Dean struggles to free himself. The demon sends Deanna flying and breaks her neck in the kitchen as she tries to crawl away. Dean grabs the Colt and rushes in to find her dead, and the demon gone. "Mary...Mary!" Dean shouts and he starts to run.

John and Mary were sitting in the Impala, which is parked next to a river. "I guess it's no secret why I brought you way out here." John said and Mary turns to him. "John –" she said but John continues. "I just – just let me get through this, okay?" He asked and Mary nods. "Okay, wait. There's things you don't know about me, John." She said. 

"So?" John said and he opens the ring box and shows it to her. "I will always love you for exactly who you are." He said when there is a bang at the window.

"What did I tell you?" Samuel, still possessed, asked. "Dad!" Mary shouts. "Sir, just listen!" John said but Samuel pulls Mary out of the car. John gets out the other side.

"Ow! Dad! You're hurting me!" Mary shouts as John runs over and tries to pull Samuel off Mary. "Hey, take it easy!" John said and Samuel grabs John's head and wrenches it sideways, breaking his neck and killing him instantly.

"No!" Mary screams as John falls to the ground. Mary drops to her knees to cradle him. The demon kicks John's legs. "You killed him." Mary cries as she looks up at him. "Oh, not just John, sweetie-pie. Mommy and Daddy too." The demon said and he unzips his jacket to show Mary the knife wound in Samuel's stomach.

"No..." she cries, softly. "Yup, afraid so. You're little orphan Mary now." the demon sniggers. "You son of a bitch!" Mary growls. "Oh, sticks and stones may break my bones, and they won't bring your family back either." The demon said. "I'll kill you, I swear to God." Mary spat. "Oh, let's not get nasty." The demon said and he sits down next to Mary.

"Now look, we both said some things that we regret. Let's, um...kiss and make up." the demon said while Mary is crying and holding John. "I'll tell you what, I'll arrange to have lover boy here brought back breathing." the demon said and Mary looks over at him.

"My parents too?" she asked. "Nope, sorry doll, that's not on the table. But, think about it, you could be done with hunting forever. The white picket fence, station wagon, couple of kids, no more monsters or fear. I'll make sure of it." said the demon. "What? And all it costs is my soul?" Mary asked him, scoffing. "Oh, no, you can keep your soul, I just need permission." The demon said. "For what?" She asked. "Mmm, in ten years I need to swing by your house for a little something, that's all." The demon said.

"For what?!" Mary asked, angrily. "Relax. As long as I'm not interrupted, nobody gets hurt, I promise. Or you can spend the rest of your life, desperate and alone." The demon said while Mary is sobbing. "Mary? It's a good deal. So what do you say?" The demon asked.

Dean drives up and sees demon kissing Mary and he gets out of the car. "No!" Dean shouts and he rushes forward with the Colt drawn. Before he can shoot, black smoke flows from Samuel's mouth and John comes back to life. "Mary?" John asked and Mary sobs with relief. "John." She said.

Castiel appears beside Dean and places a hand on his shoulder. When Mary looks up from John, Dean is gone and Samuel lies dead on the ground.

Dean was asleep in bed until gasps and wakes up. Castiel is standing near the foot of the bed. "I couldn't stop any of it. She still made the deal. She still died in the nursery, didn't she?" Dean asked as he sits up and Castiel nods. "W-What about (f/n)? Him and (m/n)? I need to..." Dean said but Castiel shakes his head. "They still die. (F/n) was in an accident a month after that. (M/n) made a deal with Azazel to save (f/n)." Castiel informs and Dean looks down, defeated. 

"Don't be too hard on yourself. You couldn't have stopped it." Castiel said and Dean stands up. "What?" he asked. "Destiny can't be changed, Dean. All roads lead to the same destination." Castiel said. "Then why'd you send me back?" Dean asked, angrily. "For the truth. Now you know everything we do." Castiel said.

"What the hell are you talking about?" Dean asked and  Castiel looks at the other bed, which hasn't been slept in, and Dean follows his gaze.

"Where's Sam?" Dean asked. "We know what Azazel did to your brother and your girlfriend. What we don't know is why – what his endgame is. He went to great lengths to cover that up." Castiel said.

"Where's Sam?" Dean asked. "425 Waterman." Castiel replied and Dean grabs his keys and his jacket. "You brother is headed down a dangerous road, Dean, and we're not sure where it leads. So stop it. Or we will." Castiel said and he disappears.

"Dean?" A voice asked and Dean turns to see (y/n) waking up. "You okay?" She asked, worried. "Get up, we've got to go." He said and she sits up. "What's wrong?" She asked. "It's Sam." He replied as he puts his boots on and (y/n) looks over to the other bed and sees Sam is gone. 

"Where's Sam?" She asked, worried, and Dean gives her a look. "425 Waterman." He replies. "How do you know that." She asked. "It's a long story but we need to go now." He said and (y/n), quickly, gets up and changes.
