The Winchester siblings are all in Bobby's study. Dean sits with a book, not reading it. Sam sits at the table. He leafs through a book. Jamie is standing against the wall with another book. "Well, you know what, at least you tried." Sam tells Dean.

"Yeah, fat lot of good it did. Why did he even come, right?"

Sam shrugs and sighs. He looks at Jamie. "So it was Cas all along?"

Jamie looks up. "It doesn't matter." She rubs her stomach.

Sam gets up. "Yes it does. Your kid is Nephilia."

Dean looks up. "A Nephi-what?" He looks at Sam.

"He is not." Jamie shoots back.

Sam raises an eyebrow. "The child of a son of heaven and a daughter of man."

Jamie smirks. "I'm not a daughter of man; I'm the daughter of a vessel. Difference."

"Jamie."

"He's not a Nephilia!"

"Hey!" Dean yells. "Can we worry about that when the kid is born and focus on Purgatory?" Dean slams the book shut. Jamie shakes her head.

"Well we're not gonna find anything with these." She waves her hand and her book floats unto a nearby pile.

Dean nods. "Yeah, Samuel's journals are pointless. I mean, I'm sorry, but uh, Jebediah Campbell has squat to tell me about how to stop Cas from cracking Purgatory."

Bobby walks in, carrying a large envelope. "And now I know why." Jamie looks at Bobby.

Bobby looks at her. "That mind thing of yours is annoying."

"Tell me about it."

Sam walks over to them. "Uh…let us in on the big secret?"

Bobby looks at the boys. "It's not about the journals we have, it's about the one we don't."

Sam shrugs. "Meaning what?"

"Well, that's the bad news. Our pal Cas didn't stop in last night just to mend fences."

"What did he do?" Dean asks.

Jamie turns to him. "He stole something."

"What?"

"The journal of one Moishe Campbell." Bobby tells them.

"Moishe?" Sam asks.

"Of the New York Campbells."

Jamie looks at her twin. "Our family tree is a little screwed up."

Sam sighs. "Well, uh, so we gotta get it back, right? Jamie do your thing."

Jamie turns to him. "What thing? I can't just magically make it appear."

Bobby holds up the envelope and hands it to Sam. "Or just read the copy I'd already made. Hi, glad to meet you. Bobby Singer. Paranoid bastard."

Jamie smirks. "I love you, Bobby."

Bobby is reading pages of the journal. Jamie gets up and looks over his shoulder. Dean is carrying three mugs. Sam sits at a desk with another book. Outside, a train whistles. "I think I zeroed in on something."

Dean walks over to him. "What do you got?" Bobby hands him the page.

Jamie looks at her brother. "Dean, let go."

He doesn't look up. "Of what?"

Jamie holds her hand out and one of the mugs flies into her hand. "The mug." She takes a sip.

Dean walks towards Sam, reading from the journal. "Went to talk to Howard Phillips about the events of March 10th." He hands him a mug and sits on the desk.

"That's March 10th, 1937." Bobby tells him.

"Alright. So who's this Phillips guy?"

"Phillips ain't his last name."

Jamie looks at Sam. "It's Lovecraft."

"Wait, H.P. Lovecraft?" Jamie nods. "Let me see that." Dean gives him the paper.

"Am I supposed to know who that is?"

Bobby looks surprised that Dean doesn't know. "Horror writer. At the Mountains Of Madness, The Call of Cthulu?"

Dean chuckles. "Yeah, it's - no, I'm - I was too busy having sex with women."

Jamie takes another drink. "You're impossible."

Bobby rolls his eyes. "Well, anyhow. There's one notion that comes up over and over again in his stories. Namely opening doors to other dimensions and letting scary crap through."

Jamie looks at Dean. "Three guesses what his inspiration was."

"You don't say." Dean mutters.

Sam looks at Bobby. "Wait, so you're saying you think Lovecraft knew something about Purgatory?"

Bobby looks at him. "All I know is Moishe paid him a visit."

Dean is sitting on the couch reading the copied journal. Jamie is curled up beside him, reading from another book. She jolts up and grips Dean's shoulder, "Dean. Dean."

Dean cringes. "Ow. Jamie, nails. What is it?" He looks at her. Dean's phone goes off. Jamie lets go of his shoulder. Dean picks up his phone and answers. "Ben?"

"There's men in the house."

"What?"

"They killed Matt. They got Mom. They're coming, I hear them."

"What are they?"

"I - I don't know."

"Did you see their eyes?"

"No."

"Teeth?"

"No."

"This is important Ben, I need to know."

"Dean, I don't know."

"Okay, where are you now?"

Sam and Bobby look up. Jamie gets up and goes over to Sam. He holds his arms out for her.

"In my room."

"Can you get to your mom's closet? I left a shotgun in there."

"No. Dean, what do I do?"

"Okay, Ben, listen to me. Go to your window and jump."

"What?!"

"Any bones you break won't compare to what they're gonna do to you, Ben. You've got to jump."

"Okay, I'm going."

"I'm coming right now. I'm coming to get you and your mom, I promise. You with me, Ben? Ben?" There's no answer. "Ben?" Dean looks at his phone.

Jamie holds her stomach. "Crowley." Dean and Sam look at her.

"Hello, Dean. " Hearing Crowley, Dean quickly puts his phone back to his ear. "Fancy a chat? God, how long's it been, Dean? Since my so-called demise, yes?"

Dean stands up. "Crowley, let 'em go now, or I swear..."

"Right, right. You'll rip me a cornucopia of orifices. Let's get to the bit where I tell you how this goes. Your chocolate's been in my peanut butter for far too long."

"I am going to kill you."

"Oh Dean, ever the wit. I've got your uh, oh what are they? Ex lady friend and not-kid, and I'm keeping them until I'm satisfied that you've backed the hell off!"

"I'm telling you, last chance to let 'em go easy."

"You're adorable when you get all threatening. Don't worry, I won't hurt them. Provided you, the not so virgin Mary, and Jolly Green stand down. Got it? Splendid. Kisses." Crowley hangs up. Dean glares at his phone.

"What's the story?" Bobby asks.

Dean looks down. "He said Lisa and Ben keep breathing as long as we sit on our thumbs."

Sam sighs. "You think Cas knows about this?"

Jamie is pacing back and forth.

"We gotta assume he does."

"So what are we gonna do?"

Jamie looks up. "We don't have much of a choice."

Dean sighs. "I'll tell you what we're not gonna do: sit here. I'm going after 'em."

Sam nods. "I'm coming with."

Dean stops him. "No, Sam. You Jamie and Bobby stay on the Lovecraft thing, okay? Cas is already way ahead of us."

Jamie steps forward. "Dean, no. You need us."

Dean turns to his sister. "Jamie, you could go into labor any time now. And then what?"

Jamie rolls her eyes. Sam turns to Dean. "You gotta be nuts if you think I'm gonna let you do this alone. Bobby and Jamie can take care of the case."

Bobby stands up. "No, guys."

"Guys, this is a big ball, okay? We can't drop it now."

Jamie nods. "Alright. You and Sam go; I'll stay here and Bobby will take Lovecraft.

"Fine. But how are you gonna find Lisa and Ben?"

Dean, Sam, and Jamie look at each other.

Bobby drives off leaving Sam, Jamie, and Dean in the yard. Jamie mixes the ingredients to summon Balthazar on top of a car. Dean lights a match and drops it in. The lights go out and Balthazar appears, a drink in his hand. "I'm sorry boys, do I look like a man-servant to you? No? No? Then quit ringing for me, please." Jamie steps into view from behind Dean and Sam. "Well, well, well. Hello Jamie. You're looking…ripe. That due date should be any day now, correct?"

"Shut up."

"Oh."

Dean steps forward. "This is important, Balthazar."

"I was drinking '75 Dom out of a soprano's navel when you called. That was important."

"Crowley's alive." Sam nods.

Balthazar takes a drink. "Well you've been scooped. Cas already told me."

Jamie nods. "Of course he did. But nothing else."

"Well did Cas tell you that he is Crowley's butt-buddy, you smug little dick?" Dean demands.

"Excuse me?"

"Handshake deal. Go halfsies on all the souls of Purgatory. He fill you in on that?" Sam continues.

"Well, yes, yes. Yes, of course he did. Yes." Balthazar is clearly lying.

Sam snickers. "Oh, yes, of course. I - I - we can read it all over your face."

Jamie looks amused. "Liar." She crosses her arms.

Dean steps forward. "Look, Crowley and Cas took two people who are very important to me."

Balthazar turns to him. "And I care about this because?"

"Because maybe there is a shred of decency underneath this - this snarky crap." Balthazar sips his drink. "They're innocent people and I'm asking for your help."

"Hmmm. I see. Fair enough." Balthazar disappears.

"Son of a bitch!" Dean yells.

Jamie looks up at the sky. "Balthazar! Don't make me pull out the prophet crap!"

Sam moves her aside. "Jamie, no. Look, Dean. Let's just call Cas. Maybe he doesn't know anything about this."

Jamie turns to him. "No."

Dean looks at him. "We are not calling Cas."

"Yeah, but Dean."

"We're not calling Cas!"

Sam sighs. "So what then?"

Jamie and Dean share a look.

Bobby is on the phone with Jamie. He is walking down the street. Jamie is outside at the yard with Sam beside her. "Lovecraft tried to jimmy a damn dimensional door. Idjit." Bobby tells her.

"So what happened?" Jamie asks, holding the phone so Sam can hear.

"Well, nothing much. Except, I dug, and every guest invited to the hoedown, dead or disappeared inside a year."

"Wow, um, so where are you off to now?" Sam asks.

"Have a chat with one of the guests."

"Wait, didn't you just say that everyone there died?"

Jamie hits Sam lightly. "Pay attention. Everybody Lovecraft invited died. I'm betting he wasn't invited by Lovecraft. Right Bobby?"

"Yeah. Seems the maid had a nine year old boy. He was there."

Sam does mental math. "So, he'd be what, 83 years old now? Where is he?"

"Same place he's been ever since the big night. Locked in a mental ward."

Jamie nods. "Of course." A fight can be heard inside the garage behind Sam and Jamie.

"Well, keep us posted, huh?" Sam says.

"Okay, stay in touch. How's things going there? You got a lead on Lisa and Ben?"

Sam glances behind him. "Well, um, we're making a few inquiries."

"Dean's ganking demons." Jamie mutters.

"Jamie!"

"What did you say?"

"I said it's slow going." Jamie and Sam hear screaming.

"How's Dean?" Bobby asks.

"About how you'd expect." Jamie says. "See ya Bobby."

"Yeah." They hang up.

Sam looks at Jamie and then glances at the door. "I'm gonna go in. You alright out here?"

"I'm not going to randomly go into labor, okay? Go make sure Dean hasn't lost his marbles."

Jamie is still standing outside. Sam walks out and they share a look. Jamie looks away and then looks back at him. He's still staring at her. She shakes her head. "No!" He sighs. She scoffs. "You do it." She walks away.

Sam closes his eyes. "Castiel, it's Sam. Um, so look, I don't know if you're in on this whole Ben-Lisa thing, but if you have any heart whatsoever, bring 'em back to us, man. C'mon. Please. I'm begging you. I am begging you, do you understand?" Sam looks around. Nothing.

"See?" Jamie tells him. He scoffs and shakes his head. Jamie frowns. As they walk away, Castiel is standing next to Sam, unseen. Jamie stops and looks in his direction before following Sam.

Sam sighs. Jamie is sitting at the table in the kitchen, her face buried in a book. Sam walks though the kitchen and pours himself a drink. Jamie looks over at him. Balthazar appears. "Drinking your feelings, Sam? I thought that was your brother's bag."

Sam looks down. "Stressful times."

Jamie looks at the angel. "Why are you here, Balthazar?"

"We need to talk."

"Why?"

"Because - I know I'm gonna live to regret this - but I'm officially on your team. You bastards." Jamie clears her throat. "Sorry, forgot there was a whore present."

Jamie smirks. "Angel whore, thank you." Jamie gets up to go get Dean.

"And we should believe you why?" Dean asks, crossing his arms.

"Would you believe I had a shred of decency?"

Jamie snickers.

"No." Sam says immediately.

"Oh. That hurts." Sam raises his eyebrows. "Okay, you're right. It's survival. You see, I asked Cas some questions and I disliked his answers. He seems awfully sure of himself for a man who wants to swallow a million nuclear reactors. I mean, these things can get a bit Chernobyl, you know? So, voilà. Consider me your double agent. Oh, and I took the liberty of searching for your friends. Uh, took a while. Crowley's a clever one."

Dean stares at him. "You found them?"

"Well, the upside is yes, uh, the downside is no, I can't get them for you."

"Why not?"

Jamie looks at Sam. "Angel-proofed."

Balthazar nods. "Indeed, the whole bloody building. I guess he doesn't trust Cas. Seems that marriage is going swimmingly."

Dean nods. "Okay, well get us as close as you can."

Balthazar nods. "Sure. But then you're on your own." He gestures to them.

Sam gets up. "Wait. Jamie can't go."

Balthazar turns to her. "Oh right. Cassie's little bun in the oven." He gestures to Jamie's stomach. Jamie raises an eyebrow. "Yes he told me."

Jamie tries not to look worried. "Who else knows?"

Balthazar shakes his head. "Not many, yet."

"Does Crowley know?"

"I couldn't say."

"Alright." Dean points to Jamie. "Then you have to watch her, Balthazar."

Jamie protests. "I don't need Balthazar to baby-sit me."

Dean turns to her. "No you need someone here in case you go into labor, and you need an angel to protect you and that baby, and since Cas isn't doing the job…"

Jamie sighs, not wanting to hear more. "Just go." Balthazar is about to teleport them. "Dean." She tosses Dean Ruby's knife.

Balthazar pops back in after taking Dean and Sam. Jamie is laying on the couch. He turns around and leans against the door frame. "I won't stay if you don't want me too."

Jamie glances at him. "I'm surprised you came back at all."

He walks in and leans against against the desk, looking at her. "You know I suspected from the beginning that you and Cas got a little too close. But I never thought this would be the result."

Jamie scoffs. "What, you didn't think the virgin angel had it in him?"

"Ooh." He smirks.

"I guess I couldn't lie about Dean being the father forever."

Balthazar scoffs. "Might be difficult when your son is born in white light and with angel powers." Jamie raises an eyebrow and looks away. "He's so strong, you know? I can feel it just radiating out."

"He's not going to have all his powers all at once is he?"

"Oh no. He'll dabble with them through childhood, but they won't be spectacular till he's ready to impress the ladies." Jamie laughs. "You laugh now. Wait 16-17 years."

"Have you met my brother, Dean?"

"Point taken."

"Am I going to be able to survive the birth?" Jamie asks seriously. Balthazar looks at her for a moment and then walks over and takes her hand.

"My dear. There is more to you than meets the eye, and that is the answer to the riddle."

Dean carries Lisa towards the stairs. Ben follows with the shotgun. A demon rushes down the stairs. "Ben!" Just as Ben aims, a shot goes off and the demon drops to the ground, Jamie hurries down the stairs holding her own shotgun. "Jamie?" Dean asks.

"Need some help?" Another demon comes up behind Jamie and grabs unto her arms, twists them behind her. "Ugh!"

"Jamie! Ben, shoot it." Jamie twists around and Ben shoots the demon in the back. Jamie punches him so that he falls off her. She and Dean share a look and then turn to Ben. "Ben? Ben!" Ben is staring at the demon.

"Dean –"

"Come on, pull it together, do you want your mom to die? Let's go."

Jamie claps Ben on the shoulder. "Come on, kid, come on." She goes to Dean. "We gotta get Sam. This way." Jamie leads them down the hall. They walk farther. Two more demons catch them. Jamie and Ben raise their shotguns and shoot. They walk down the stairs and hear pounding on a door. "Sam?"

"Dean!" Sam yells from inside the room.

"Sam?"

Jamie points to the door. "There. He's locked in."

"I'm in here!" Dean starts to put Lisa down but Jamie stops him. She pushes Ben back and motions for Dean to step back. She waves her hand and the door slides away. Sam comes out. "Jamie?"

Jamie nods over her shoulder. "Lisa is hurt. Come on."

"Come on, we gotta get to a hospital. Ben, give the gun to him. Sam, Jamie, we need a ride."

Ben gives Sam the gun. Jamie leads them out of the building, Dean follows with Lisa, then Ben, and Sam is last looking around with the gun.

Outside the building Sam pulls up in a car he's stolen, Jamie is in the backseat. She kicks open the door for Dean. "Here."

"Go, go, go, go."Dean says to Ben. He gets in shotgun. Jamie gets Dean get Lisa in the backseat. She pulls bandages out of the med kit. Dean looks at Lisa's blood on his hand. Jamie gives him a wide-eyed look, as she hands him clean gauze. Ben turns around, worried. "She's fine, Ben. She's fine. She's gonna be just fine. Almost there." He whispers to Lisa. "Hey, hey. Stay with me." He looks up. "Sam, you gotta go faster, man!"

Sam looks back at them. "Sam." Jamie says grimly. Ben turns around and looks at them again. "Ben, face forward! Now." Jamie tells him.

Dean talks to Lisa. "You're gonna be fine. You're gonna be just fine."

Lisa is lying unconscious in her hospital bed. She is hooked up to several breathing tubes and monitors. Dean and Ben sit on either side of the bed. Dean looks at Ben. "Ben, I'm sorry." Ben gets up and goes to the door. "Ben."

Castiel appears. Jamie walks in front the hall. "Cas." She mutters.

Dean looks over and sees him there. He scowls. "What do you want?"

"Dean, listen."

He shakes his head. "What do you want me to say? She'll be dead by midnight."

"I'm sorry."

"I don't care. It's too little, too late."

Cas sighs. "Okay. Well, regardless, I didn't come for you."

Dean looks at him. "Meaning?"

Cas walks up to Lisa and places his hand on her forehead, healing her. He turns to Dean. "She's fine now. She'll wake soon. Dean, I said I'm sorry and I meant it." He glances back at Jamie. Jamie looks away.

"Thank you. I wish this changed anything." Dean is visibly upset.

"I know. So do I. All else aside, I just wanted to fix what I could." Castiel walks towards Jamie. She looks up at him. He leans down and they kiss. She pulls away and smacks him across the face, tears in her eyes. She goes outside. Castiel turns and looks at Dean.

"There's one more thing you could do for me."

Soon afterwards, Lisa wakes up. Ben is sitting on her hospital bed. "Hey, Mom."

"Hey. What - ?"

"You're in the hospital."

Outside the room, Dean walks up to the door and watches.

"What happened?"

"We were in a car crash."

"Are you okay?" She asks her son, concerned.

"Y - Yeah, I'm - I'm fine. You hit your head pretty bad, but you're okay now."

Dean knocks and takes a step inside. "Hi."

Lisa raises her eyebrows, not recognizing him.

"Who're you?" Ben asks.

Dean looks sheepish. "I, I'm Dean. Uh, I'm the guy who hit you."

"Oh." Lisa says softly.

"I just, uh, I lost control for a minute, and I just wanted to say that I'm sorry."

"Dean?" Jamie walks over to him, her hands on her belly. "What are you doing in here?"

Dean looks at her questioningly. "Uh…hi honey."

Lisa looks at Dean. "Is this your wife?"

Dean pauses. "Uh…yeah. Yeah, she is."

Lisa smiles. "Your first baby?"

"Yeah." He reaches over and puts his hand on Jamie's stomach. Jamie smiles and puts her hands on Dean's. He looks back at Lisa and Ben. "I um…I'm real happy you two are both okay. And uh, I'm just - I'm glad your life can get back to normal now." He tries to smile.

Lisa gives him a smile. "We're okay, so - so that's what's important, right?"

Dean nods. "Yeah. Anyway, uh, we'll leave you two alone." He points at Ben and then points to Lisa. "You take care of your mom."

Ben nods. Jamie waves goodbye to Lisa who waves back. Dean and Jamie walk away, and then stop once Lisa and Ben can no longer see them. Jamie frowns and looks up at Dean whose fighting back tears. She pulls him into a hug.

Dean and Jamie walk down the stairs and across the street to the Impala. Sam is standing on the other side of the car waiting for them. "Well?"

"Well nothing." Dean opens Jamie's door for her and then gets in the car. Sam looks at Jamie and they get in the car as well.

Sam sighs. "Dean, you know, you've pulled some shady crap before, but this –" he shakes his head. "- has got to be the worst." He scoffs. "Whitewashing their memories? Take it from somebody who knows –"

Dean turns sharply to him. "If you ever mention Lisa and Ben to me again, I will break your nose."

"Dean."

"Sam." Jamie grabs Sam's shoulder. "Stop."

"I'm not kidding." He glances back. "You too, Jamie." Sam is about to protest, but Dean looks at him and he sees the tears in Dean's eyes, so he nods. Jamie frowns and sits back. Sam closes his door and they drive off.
