A/n: I've explained before that Mark isn't a Nephilim because Jamie is a vessel of Michael, and vessels are different from ordinary humans because they are meant to house angels. So Mark has grace, and the powers of heaven, but his true form is human, he has no 'greater' angelic form, and more importantly he has a soul. I guess more specifically he has Adam's soul. Secondly, Mark can't be sensed by the angels because of the cloaking sigil infused with Dean's amulet, and Metatron cannot sense Jamie. He can sense her power, so he knows the Voice is on earth, but he can't tie it to her because Cas branded her ribs.

"Jamie! Could use some help!" The blonde hunter's head shoots up from the book she's reading as she watches her oldest brother half-drag half-carry his injured angel into the room, followed by her twin brother, pain and shaking, barely able to walk.

"Ah hell." Jamie is up and at Sam's side before he even registers her presence. She loops his thick arm over her shoulders and takes on most of his weight. "Put him on the table, Dean." She tells her brother, raising her hand in front of her. Instantly the books occupying the large dining table float from the surface and deposit themselves in neat stacks on the floor, out of the way. Dean heaves Cas unto the table. "I'll put Sam to bed."

She drags her 6'4 brother into his darken room at the end of the hall. "Don't need you…" Sam is muttering, but Jamie simply shakes her head and ignores him. She uses her telekinesis to flick on the light and dumps her twin unto his bed. Sam promptly passes out as soon as his body makes contact with the mattress, leaving his twin shaking her head and pulling off his boots. She un-buttons his collared shirt throws it to the floor, frowning at how limp her brother is, and then maneuvers his jeans off. She tucks his legs under the comforter and sits with him a moment before planting a cool kiss on his warm brow and turning off the light.

Back in the main room Dean is cleaning blood from Cas's skin. The angel is completely shirtless, and various medical paraphernalia is scattered on the table. "He isn't healing." Dean says gravely, not looking up from his work.

"His grace is probably damaged. Crowley shot him with an angel bullet and then reached inside his abdomen to grab the damn tablet." Jamie walked over to the table, confirming her suspicion that Cas was indeed unconscious. "Did he pass out on his own or did you knock him out?"

Dean gestured to the used syringe, and she nods. "I'm gonna try to stitch this up, but I only have so many dissolving stitches, the rest is dental floss. Do you think angels get infections? That wound is too deep to disinfect with alcohol."

"Just pack the wound. I'm going to get Mark." Jamie tells him, turning away. They don't like to rely on their son for healing. He's too young and they fear he's harm himself with the effort and focus it requires. The only times have been matters of life and death, and even then Mark did it of his own volition, not by their coaxing. "Mark." She calls softly, flicking on the light to her son's room.

"Mama?" The boys yawns sleepily, sitting up.

"Come with me, Mark." She says, picking the boy up and carrying him out to the main room.

"Daddy." The half angel reaches out to Dean, takes him in his arms. Mark wraps his arms around Dean's neck gleefully, but his smile fades when he senses his father's duress. "Daddy?"

"There's something I need you to do, Mark." The hunter tells his son. "Something important." He carries Mark over to the table and sets him next to Cas. "You remember Castiel, right?"

Mark stares at the shirtless man for a long moment. He has scattered memories of his face. He remembers going to the zoo one autumn afternoon. He remembers the man speaking emotionally with his father in a parking lot after a hunt. He remembers playing with pots and pans and his mother's keys while the man looked on. And he has memories that are not his, rather the product of the psychic connection bred by his grace. The man bleeding and begging with his mother and father in a stark white room. A voice vowing to protect his mother. And strong arms that protected his father, hands that raised him from hell. After a moment Mark nods.

"He's hurt bad, son. Can you help him?" His mother asks, almost timidly. The emotions he feels coming off his father are strong, and he recognizes love, a love different and yet the same as the kind his parents feel for him and for each other. Slowly he nods and reaches forward.

It takes a moment, it's not instantious yet. He's still too young for that. And he can't heal Cas entirely, he can only stop the bleeding. The angel blinks and opens his eyes. "Mark?" He asks, staring curiously at the boy.

"That was very good, son." Dean whisphers, taking the boy from the table and handing him to his mother. "Go back to sleep." The hunter plants a kiss in the boy's hair and then one on his mother's cheek, coaxing both of them to bed. "I'll be there soon, Jamie."

"I can sleep in Mark's bed if you want to…I mean, Cas probably doesn't need to…" There's red in her cheeks now, and there's red growing Dean's as well. She takes the hint and carries their son back to his room.

Dean turns to Cas and Cas stares at Dean with wide sapphire eyes, bluer then ocean seas, and Dean drinks it in. "How are you feeling?" He asks, almost hoarsely.

"I'll heal. It will take time. Mark merely clotted the wound, began the scarification process." Cas replies. Dean nods, turning away. "Dean." The hunter glances behind him. "I'm sorry."

The next morning Jamie and Dean both walk in carrying heavy stacks of files. Sam is sitting at the table and he watches them tiredly. "Please tell me that's everything."

Dean looks up with a grin. "Yeah." He chuckles humorlessly. "No, not even close. You see, the Men of Letters kept files on every demonic possession for the last 300 years." He picks up a file and looks through it. "I mean, we've got Borden, Lizzy, all the way to Crane, Ichabod."

"The headless horseman was a demon?" Jamie looks impressed. "Hmm."

"Aah." Sam says in feigned amusment.

Dean frowns. "How you feeling?"

Sam looks at him, and then at their sister. Jamie frowns. Sam looks back to their brother. "Honestly, um... My, uh, my whole body hurts. I feel nauseous and like I'm starving at the same time, and everything smells like rotting meat."

Jamie crosses her arms looking worried. "Rotting meat? Like charred or left in the sun too long?"

"Left in the sun too long. Why?"

"Just wanna make sure your brain isn't cooking." She tells him. He frowns.

Dean smiles to himself. "I've had that hangover. Jaeger, man." He looks towards Sam. "Maybe you should, uh, take a break, get some air."

Sam shakes her head. "Dean, the only thing that's gonna make me feel better is finishing this."

"All right. Well, I'll go get you some grub, keep your strength up." Dean leaves.

Castiel enters the room. "Morning." Jamie glances over at him and then averts her eyes. Sam glances up briefly and then goes back to the file he's reading. Cas frowns and looks around. "I like this bunker. It's orderly."

"Oh, give us a few months. Dean wants to get a ping-pong table."

Cas tries to sound amused. "I've heard of that. It's a game, right?" He steps down and goes to grab a chair, but as he does he groans. Jamie's head shoots up and she moves to his side.

"Are you okay?" Sam asks, slightly worried.

Jamie puts her hand against Cas's abdomen, her fingers ghosting the position of his wound. He gives her a reassuring smile. "My wound isn't healing as quickly as I'd hoped... But I am getting better." Jamie doesn't believe him but she moves away. Cas turns his attention back to Sam. "And you're getting worse."

"Well, two trials down, one to go."

"And the final test, do you - you know what it is?"

"I have to cure a Demon."

Cas chuckles. "Of what?"

Jamie picks up another file. "That's what we're trying to figure out."

Dean comes back in with a tray. There's three peanut butter cups, some jerky and an open beer on the plate. "Soup's on. There we go." He sets the tray in front of Sam and sips the open beer. "I think this is, uh... Oh, it's still good."

Jamie stares at the tray in disgust. Sam looks like he wants to vomit. "A half-drunk beer, jerky, and three peanut-butter cups?" he glances accusingly at Dean.

"Yeah, we're - we're running a little low." Jamie glares at him. "I'll make a run." He says defensively.

Cas gets up immediately. "Dean, I can go with you." When Dean doesn't acknowledge him Cas tries again. "Dean. I'm sorry."

"For what?" he shoots back.

"For everything."

Dean raises an eyebrow. "Everything? Like, uh... Like ignoring us?"

"Yes." He replies honestly.

"Or like bolting off with the Angel Tablet, then losing it 'cause you didn't trust me? You didn't trust me."

"Yes."

Sam and Jamie share a look, but neither say anything, both realizing that Cas has hurt Dean deeply, and he needs time to forgive. And forgiveness is not something Dean Winchester doles out lightly. ""Yeah. Nah, that's not gonna cut it. Not this time. So you can take your little apology and you cram it up your ass."

Cas sighs, resigned. "Dean, I thought I was doing the right thing."

The hunter nods. "Yeah, you always do."

Sam stares at Jamie. It takes him a moment he is able to tap their telepathic link. "Okay…time to break them up."

"Yeah, ya think?"Jamie moves to step between her brother and his angel. "Okay. Um. I'm gonna go get real food because Mark can't eat any of that. Cas, come help me." She says forcefully.

Sam clears his throat to get Dean's attention. "Hey, uh, do we have a room 7B?"

"Goddamnit, Cas." Jamie whirls around once Dean and Sam are gone. Cas looks up at her. Those damn sapphires eyes. Her son resembles her brother in every except those damn eyes. She has stared into those eyes for three long years. She frowns. "It's been a long time." She says quietly. He nods, taking a step forward. She doesn't move. He reaches her, and they stare into each other's eyes until he leans forward and she grips the back of his neck, pulling him into a deep kiss. He grabs for her shoulders, deepening the kiss. She kisses back, sloppy, needy, the response he'd get from Dean if the hunter would ever get over himself. She knows this. His kiss is soft, but firm, and she can also taste AJ on his lips. This is way it was, years ago, and she can't help but realize it's been years, long years. They've taken their toll. The first time she kissed him she was young, alert, and grieving. Now she's a mother, and her innocence is long gone. He was an obedient angel then, and now she isn't sure what he is.

"Jamie." The way he whispers her name causes goosebumps to form on her pale skin. She breaks the kiss, glancing up into his eyes again. The question in his eyes gives her pause. She considers it for a moment and then pulls away, heading in the direction of her room. After a moment he follows her.

She checks on her kids first. Emmy is asleep in her crib. Mark is awake, but he's playing quietly on the floor by his bed, his toys float in the air around his head, until he chooses the truck he intends to race on the old track that resembles his father's old toy. Jamie quietly closes his door and then opens the door to her room. Dean's room.

Cas is on her heels, his breath is hot on her neck. He pulls the door closed behind her. She turns to him and then quickly strips of her clothes. His sapphire eyes drink in her form as every inch of her pale skin is revealed to him. But it doesn't last. She mutters a few choice words and her appearance is transformed. She takes Dean's form and he relishes in the facade. An illicit appearance for an illicit affair.

He strips his clothes with angel speed and grabs her roughly. The spell bleeds every inch of Dean's skin unto her form, and he worships the idol with tongue and teeth, holding her firmly against Dean's sheets. Their affair is short lived. Nothing has changed between them. She is not the Winchester he loves, and he is not her long dead lover. The years of grieving have not ended for her, she does not want him, she just wants the feel of skin against her own. The chaste relationship with her brother can only go so far.

He watches her dress with genuine curiosity. As her form becomes her own again he takes in her true appearance, finding it almost as interesting as the desired form she had forsaken. "I've always wondered…" His voice is husky and low. For a second she craves a cigarette. "Why aren't your eyes green?"

"My mother had blue eyes." She answers quietly, pulling her hair into a ponytail and grabbing her jacket.

"I see. Is it…common for one sibling to have different color from another?"

"It just the way genes work, Cas." She's lacing her boots.

"But you and Sam…"

"Are fraternal twins, two separate sets of genes. Besides Dean and Sam don't exactly look alike."

"No. Sam seems to look more like your father, while Dean resembles your mother."

"Sam is actually a good mix of Mom and Dad, but whatever." The sounds of Dean and Sam coming down the hall cause them to turn away. "Hey guys." Jamie says softly, turning to look at them.

"Hey, we found something." Sam holds up an old roll of projector film. Jamie studies it curiously.

Sam finishes setting up the projector just as Jamie comes in with a bowl of popcorn and Mark on her hip. Dean is sitting at the table holding Emmy on his lap. Cas is seated across from him. Jamie sits down opposite of Sam. The projector starts clicking. A young priest comes into view.

"Simon, we're filming." Comes a female voice.

"Um, hello, world." The priest says nervously.

"So this new ritualwe're going to see, this new type of exorcism,h-how does it work?"

"I don't know. It's my first time."

The camera turns to focus on the source of the female voice. Jamie raises an eyebrow. "Wait, is that Abaddon?"

"Aah! Aah!" A different woman screams.

Dean glances towards his sister. "It's not killy enough. It's got to be the, uh, the chick she possessed."

There's screaming and grunting coming from a woman chained to the floor. Obviously possessed. "Hurry. We must do it now." A new priest comes on screen.

"Dead! They're all dead! Everyone you ever loved..." The possess woman hisses.

"Hey, those chains look exactly like the ones in our dungeon." Sam exclaims.

"In your what?" Cas asks.

Dean scoffs. "Demon on a leash - cool."

The screaming, grunting continue from the woman. "Aah! Aah! Aah!"

"Exorcizamus te, omnis immundus spiritus...hanc animam redintegra..." The priest cuts his own hand. "Lustra! Lustra!" He grabs the woman, putting his cut hand over her mouth and holding her down.

Suddenly her chest cracks open and she falls dead. "She's dead." The priest coughs, the camera shakes. "Where's the demon?"

"Stop filming."

"What happened?"

"Will you just stop?!"

The film strip ends. Dean looks down at her daughter and then to his brother. "Well, that was weird... With three exclamation points."

Sam shakes his head. "That wasn't a normal exorcism. They changed the words."

Jamie gets up, holding Mark. "Hanc animam redintegra means fix this soul."

"I believe "lustra" is Latin for wash or cleanse." Castiel looks to them.

Jamie shakes her head. "No, purgo is the root for cleanse. Lustra is closer to…haunts. Fix what haunts this soul or fix the soul that haunts."

Dean rolls his eyes as he gets up and hands Emmy to Jamie. "Oh, yeah, 'cause that was the most freaky thing was the vocabulary. What about the bloody high five or the chest burster? Anything else on the film, like director's commentary, sequel, maybe?"

Sam is looking through a file. "Yeah, listen to this. The older priest, Max Thompson, bit the dust in '58, but the younger one is still alive and still in St. Louis."

Dean considers. "Think this kind of weird is worth the drive?"

"Dean, everything in those folders - the possessions, the deals, all of it - we've seen that before, but that - That was all new. Yeah, it's worth the drive." Sam tells him.

"It's definitely worth the drive." Jamie agrees. "Go check it out."

"All right. Let's roll." Castiel stands up, but Dean puts his hand up. "Not you."

"Sam is more damaged than I am." Cas protests.

Dean shakes his head, not wanting to argue. "Yeah, well, you know, even banged up, Sammy comes through."

"Dean, I just want to help." He begs.

"We don't need your help. Just stay here and - and get better." Dean walks away. Sam glances at Cas and sighs. Jamie follows after Dean with their kids.

Outside Dean buckles Emmy into her carseat on one side while Jamie buckles in Mark on the other side. "Dean, Crowley is plotting something. You and Sam have to be careful." Jamie tells him.

"Yeah. Well that's why we have to get out the kids out of here." Dean puts a heavily packed bag in the back of Jamie's SUV. "Just like we planned."

Jamie nods. "I'll get the kids up to North Dakota, and then I'll be back to help with the last trial." Dean hugs her and then turns away.
