Chapter: Through the Magic door

He's always done his best to make life miserable for the humans. No matter how much he likes the individuals. Its his job to make their lives a living hell and while he's never had a problem coming up with fresh, new, inventive torments … well, they always seemed to one up him. Crowley's always said there's a flaw in the design of humans. A very real talent, one he doesn't really enjoy exploiting; what's the fun in humans being the purveyors of their own demise? And its always a surprise to them. The end, that is.

"I've said it before; this world they're born into is against them from the get go. Yet they still put all their being into making it so much worse! Its baffling, really."

"What is?" Aziraphale looks up from his tea cup. He's been half listening to what Crowley has been saying the past five hours but the chatter from Heaven has taken most of his attention.

"You've been ignoring me in favor of angel radio." Crowley states with a huff. "Don't deny it."

Aziraphale closes his mouth. He takes a slow sip of his tea and stares at the floor. Crowley isn't patient, which they both know, but even the hiss of the snakey sound doesn't penetrate the focus the angel has on Heaven.

"What is it?"

"Hmm?" Aziraphale looks up, his most innocent expression in place, and it does nothing to convince Crowley.

"Oh, bother." Crowley utters an annoyed hiss and sets his tea aside. "You're listening to the arguing up there. Aren't you?"

"How do you kn-?" Aziraphale clamps his mouth shut because he's already said more than enough.

"Its what you do." Crowley sighs tiredly. "Listen, we're not interfering in the plan. That's been in motion for… well, who knows how long this time. My point is, we've made sure they've got the book and both sides are looking for the next clue."

"Then its more reason not to get involved. We really can't, you know." Aziraphale eyes Crowley, his tone very strict, more than usual, which is a bit of a surprise to them both.

"…not…" Crowley's eyes narrow. "This bloody mess, this apocalypse is because your bloody side is 'interfering' with the ineffable plan! Which they're not supposed to do!"

Aziraphale calmly averts his gaze and takes a long sip of his lukewarm tea. He can't deny his brothers and sisters have stuck their feathers in where they shouldn't and he can't do anything about it. But if he's to believe Crowley, then they have every right and should do everything in their power to balance the scales for the final test.

"What did you have in mind?" because he rather enjoys the world as it is and he'd really like it to stay this way for a bit longer. Though, Crowley's smile is enough to make Aziraphale regret even asking that.

The patch of woods is eerily silent. Sam can't hear the chirp of birds or scuttle of rodents anywhere. Which gives him the heebies and then there's the issue of his girly-half bitching at him the entire ride, like he's to blame.

Well… So maybe some of it he should take responsibility for. But he's hesitant because they already hate him enough just for being the boy-version of their Sam. Its like he's…intruding.

Sam can remember wanting this, a family. He wanted to be a normal kid, yeah, but above all of it was the desire to have a family, to belong. Well, here they all are. His Mom and Dad, both alive and well. His grandparents, even if Samuel Campbell is still a douche. And his cousins' Mark, Gwen and Christian. They don't keep that much a distance as his grandparents. But they don't automatically include him either, it feels like he's the last one picked for the team. Always the new kid…

Henry stops, head slightly bent towards the left as though listening and Sam mimics the move. Still nothing, no other sounds and the rest of the Hunters have remained a few miles behind.

"This is the place." Henry murmurs then steps forward, hand stretched out in front of him. "Hello?" he calls out and stops again. "Cuthbert, its Henry. I wish to speak with you."

Samantha moves to stand beside her grandfather, looking around and seeing nothing different.

"Cuthbert, please?" Henry asks again. "I'm not alone but they don't mean you any harm either…" he trails off as a shimmer of blue forms a few feet ahead and shapes into a door.

"So…?" Samantha looks up at him, her brow furrowed, head tilted towards the door.

"Behave." Henry orders then glances over his shoulder to Sam. "Both of you."

Sam just frowns, then follows them both inside. He doesn't see where he needs to be told to mind his manners when its Samantha acting like a child.

"The Hunt was in a book Sam found at the Bunker." Diana shifted in her seat and avoided their eyes as she went over the information again. "The same book I found, only…" the version of the book in this verse was missing the Hunt Samantha had found. "We weren't the first or the second… She knew I wouldn't let her go alone." She sighs at how easily she allowed her little sister to play her.

"What was the Hunt?" Bobby's gruff voice breaks the momentary silence.

Diana sort of laughs. She hadn't told them what they'd been hunting when they asked her about the Hunt the first time. "You're not gonna believe me, but alright." She draws a breath and looks at them. "It's a Witchling."

"A what?" Dean frowns as he leans forward on the table.

"Witchiling. Part witch." Diana explains.

Dean stares at her when she doesn't say more. "…and what else?"

Diana shrugs. "A little of everything else. There's no specific mention of 'what else'."

"What got your sister so interested?" Bobby cut in before Dean had a chance to pick a fight, as usual.

"Sam's the curious type." Diana shrugs again and Dean is getting more annoyed. "She wanted to see it. And, find out what happened to the others that went to Hunt it before us. You know the rest…"

"No," Dean shakes his head. "I don't."

Diana rolls her eyes. "OhMyGod, dude!" she glares at him. "You and your brother were there. I got yanked here and your brother got tossed there."

Dean is nodding. "Yeah, that part I got. I don't get why the hell it happened."

"You lost me." Diana sits back in her chair wearing a slight frown on her face. "Now, huh?"

"Why the swap?" Dean repeats but her expression doesn't change much.

"What do you mean?" Diana wonders. "I'm pretty sure the others ended up swapped. Who knows who got swapped in their place but I would assume its self-defense on the Witchling's part." She arches a dark eyebrow at Dean as if that should have been clear.

Bobby waves a hand at Dean that stops whatever smart ass remark he's about to make and turns his attention to Diana. "What do you remember?"

Diana thinks back to when Samantha tossed her the book and said they had to Hunt it down. "The book was precise. The place was exactly where it was in the book. It looked how it was described." She frowned down at her hands on the table. "I don't know if the other locations where the same-."

"Other?" Dean cut in. "How many?"

"Uhm, 4 total." Diana tries to remember what else the book said-.

"4?" Dean echoes. "Why'd you pick this one?"

Another shrug has Dean gritting his teeth. "Closest 'X'." she turns to Bobby. "I'm pretty sure Sammy was going to drag me along to verify the other 3."

"And where are those?" Bobby grabs the map on the table and starts to spread it out.

She frowns. "…I…" Diana huffs in confused annoyance. "I don't…know."

"We're not fucking around, Diana!" Dean gets to his feet and starts pacing.

"Dude," she glares at him. "You yell at me one more time…"

"How don't you know where the other locations are?" Bobby leans forward and draws her glare.

"Because I don't." Diana runs both hands through her loose hair. "Its… it's a frigging blank in my brain." She's a little scared to admit it. "I can't remember the where," she looks up at them. "I just know there is."

"What the fuck…" Dean breathes out in frustration.

"Ditto." Diana nods her agreement. "So help me get Frank to find Magnus." She stands up and waits for Bobby to stand up. "Because he's the only lead I have."

Sam slowly walks down the hallway, gun held securely in his hand. He tried to listen for sounds of the others but he hadn't found Henry or Samantha since they'd stepped through.

"…if I could go back and change all of it…"

Sam paused.

"…you can't…"

He turned left and slowly went forward. At the next arch, he stopped as the voices became clearer.

"How many times have you pulled a stunt like this? Too many and every time you do…"

Sam frowned at the sound that followed; a sort of whimper and then; "I know."

He hesitated but then took a step into the room and found that Samantha was talking to Mary.

"Doesn't look that way." Mary crossed her arms and glared at Samantha. "We've been here before, Samantha. And every time there's an 'I'm sorry'. Only this time your sister isn't here. She's gone."

"I know, Mom. I know and I'm so-."

"Don't you dare, Samantha Winchester." Mary pointed a finger in Samantha's face. Sam just stared, confused as to how Mary was even there. She hadn't come along-.

"I'll get her back." Samantha promised. "I swear it, Mom."

"How?" Mary demanded. "Tell me how you're getting Diana home."

"Mom-."

"You have no idea, no clue. And if you even start with your damn 'I'm sorry' one more time!" Mary warned.

Sam frowned as Samantha ducked her face and sniffled.

"I didn't mean for any of this to happen." Samantha whispered in a teary voice. "I just wanted to see if it was still there, find out what happened to the others-."

"How many times are you going to do this?" Mary yelled as she threw her hands up in frustration. "This self-centered, selfish behavior has got to change, I'm not going to put up with it anymore!"

Sam took a step towards the pair-.

"Before you start your charge…"

Sam turned towards the man suddenly at his left.

"Don't you want to hear some more?" he smiled. "Its very interesting." He kept smiling as he turned to the pair of women. "I'm learning a lot."

"Who are you?" Sam raised his gun and glared at the still smiling stranger.

"Hello." The pasty face and frozen smile didn't waver.

Sam frowned. "Let her out… whatever that is."

"That?" the smile sort of tilted to one side of his mouth as he glanced to the women once more. "It's a very simple glamour." He turned to Sam and grinned. "It helps me get the truth. I need to know why you're all here."

Sam lost his frown and slightly lowered the gun. "You're… Cuthbert Sinclair? The Man of Letters?"

"Well, had been a long time ago." He nodded with that same creepy smile that was making Sam more uncomfortable.

"Then you know we came with Henry." Sam points out. "That's Samantha Winchester and she's a Woman of Letters."

"Yes," Cuthbert's smile lost some of its shine. "Henry did mention that…" he took another step closer to Sam, brow slightly furrowed as he studied the Hunter. "However… neither of you are telling the truth."

Sam tried to lean away from the reaching hand. "No, don't!"

Cuthbert placed his palm on Sam's forehead. "Oh…" he could see the flames and the girl splayed on the ceiling. The string of hotels and schools, long nights on the road with the sound of the engine his lullaby. The fights with his Father and sometimes with his brother. Running away and feeling like he'd just learned to breathe for the first time. The exhilaration of being alone in the field with his brother and setting off those fireworks. All the beautiful lights in the sky… walking away from them. Leaving and making his way through college, falling in love… Cuthbert could see all of it.

"Old friend…" Cuthbert glanced around Sam and gave Henry a soft smile. "You should see this." He took hold of Henry's hand and showed him everything.

Diana pulls off the road and hides her pretty black Defender in the trees. She doesn't get out right away… ever since she found Cuthbert's old files and Frank used them to locate his lair, she's been just a little afraid. What if he can't help her get home? What if she's stuck…?

And then Diana wondered if maybe it would be so bad if she didn't make it back to her reality… she guessed there would be worse places she could have ended up. Also, it wasn't like she was abandoning her sister. There were the Men Of Letters and the Hunters, plus they had all their family and friends to back up Samantha.

Who was going to be here for Dean?

After what he'd told her… well, it wasn't like his Sam was too concerned with having his brothers six, unconditionally. And isn't that what family was supposed to do? Was she really just going to leave her boy-bits to fend for himself when there were those shark fugly's to take care of?

"…Earth to Diana…" Dean shoves his hand in front of her face to get her attention.

"Alright, these are the coordinates Frank gave us." Bobby says from the back seat.

"Yup." Diana quickly jumps out and grabs her bag. She puts the strap over her shoulder and walks around to the front of her Defender.

"Baby has more room." Dean grumbles as he closes the passenger door.

Diana rolls her eyes at the old complaint. "And your Leviathan doppelganger has done an awesome job of making her too damn popular to drive."

"Alright." Bobby grumbles at them. "Lets find this magician."

"He's a Master of Spells." Diana corrects, once again. "Not Merlyn… fine." She starts walking when they just look at her like there isn't a difference.

They've all put in their two cents since she found the files on Cuthbert and asked Frank to find him. Thinking of Frank put her in mind of another genius to look up. The Bunker was seriously out of date and locating those files would have been easier if she'd had the app.

"We're lost." Dean grumbles a curse when he trips on a root.

"Not lost." Diana pushes a branch out of her way and keeps walking. All she needs is to have Frank locate Charlie-.

"How do you know?"

"There's a door here." Diana assures.

"Yeah, you keep saying that." Dean calls to her back. "Still don't see a door."

"Shut up and just follow me." Diana orders with a frown over her shoulder.

"Follow?!" Dean exclaims. "You've never even been here!"

"Shush…" Diana slows her pace and takes a closer look at the trees she passes.

"What?"

"Its here…" Diana mutters. "Somewhere.."

"Oh come on!" Dean throws his hands up and turns to Bobby. "We're in the middle of nowhere."

Bobby just shrugs. This was the location that Frank had given them thanks to the files at the Bunker.

"You're not helping." Diana snaps at her boy-version. "I know its here. I can…" she turns in a slow circle, brow furrowed. "…feel it."

"Feel a door?" Dean echoes incredulously.

"You okay?" Bobby steps closer, a little concerned.

"Maybe it's the air." Dean notes with sarcasm. "Its too thin or something."

"Just let me concentrate." She glares at Dean, turning away from him.

They watch her, head tilted as if she's listening for something… its like a soft echo, she can't make out the words but the voice is so familiar.

Henry's eyes keep sliding to Sam but the boy isn't looking at any of them. Samantha is angry, she hasn't taken her glare off Cuthbert.

"How very nice of you to visit, old friend." Cuthbert steps towards Henry with open arms and envelopes the Man of Letters in a hug.

Henry's just a bit surprised by the warm welcome and belatedly pats Cuthbert's back. "What is-."

"I do hope you all understand-." Cuthbert steps away from Henry and turns that creepy smile on the others.

"What the hell was that?" Samantha demands.

" …" Cuthbert stares at the angry girl then turns to Sam. "Now that I know why you're all here-."

"You could've just asked." Samantha yells.

"Yes," Cuthbert agrees and smiles again. "But this way I know why you are really here. And not why you want me to think you're here."

"What?" Sam frowns, not sure if the ex-Man of Letters is messing with them.

"Cuthbert," Henry steps forward. "Can you help us get my granddaughter back?"

"Well of course." Cuthbert assures. "It's a much simpler solution than the forgetting spell the witchling placed on your other granddaughter."

"Say what?" Samantha steps closer.

"It's a precaution, a way to protect itself." Cuthbert turns to Henry. "Although it seems a simple enough thing… I assure it's a lot more complicated. And I assume you would rather not kill your granddaughter."

"Kill? What the hell…?" Samantha grabs her gun but Henry raises his arm to stall her.

"Please, explain yourself, Cuthbert?" Henry sends a warning glace to Samantha but she doesn't put her gun away.

"Of course," Cuthbert nods agreement and starts walking past Sam to lead them into his living room. "Trying to break, lift, remove, alter or tamper in anyway will only serve to kill her."

Sam follows them into a room filled with cabinets and pedestals that hold all sorts of artifacts.

"Then what am I supposed to do?" Samantha demands while Cuthbert offers them drinks.

When he just smiles at them and starts pouring Henry closes the distance between them and takes the first drink.

"Old friend," Henry sets the drink down and stops Cuthbert from pouring another. "I came to ask for your help."

"I know." Cuthbert nods smiling.

"Then how do I get my sister back?" Samantha steps closer only for Sam to grab her arm. She glared at him but his eyes pointed out the gun she still held.

"Simple," Cuthbert winks at them. "Just go there."

Sam can see his girly version doesn't like that answer. He takes the gun from her and yanks her away from the ex-Man of Letters. "How?"

Cuthbert hasn't lost his smile. He turns to stare at Henry.

"What?" Henry glances at all of them, not sure what he's supposed to do when Cuthbert rolls his eyes.

"Have you forgotten everything, Henry?" Cuthbert's tone is just a little bit teasing.

"Gran-pops?" Samantha steps around Sam and waits but Henry doesn't know what Cuthbert is talking about.

"Very well," Cuthbert waves them to follow. "You need a refresher. Come along now."

"Now she's hearing voices?" Dean whispers to Bobby as they pace the clearing Diana stumbled into.

"Frank says this is the place." Bobby tells him again. "And we've got the ingredients the girl wrote down to bust the lock." He smacks a hand on Dean's chest and tilts his head to where Diana has stopped. "Just let her alone for a bit."

"Fine." Dean grumbles.

"So…" Diana huffs a breath. "My name's Diana… Winchester." She grits her teeth and almost glances over her shoulder to where Dean and Bobby are waiting. "I am a Woman of Letters." She takes another step towards the center of the clearing. "Cuthbert Sinclair? I've come to ask for your help…" she waits, shuffles from one foot the other but there's no response. She closes her eyes and takes another breath, trying to listen for that echo from before…

"A Woman of Letters?"

Bobby and Dean turn to the man walking into the clearing from their left.

"There haven't been any Men…or Women of Letter since '58." He stops a few feet away from Diana, hands crossed in front of himself.

"…58'?" Diana breathes. "Right, Mr. Sinclair," she blinks the sudden sting of tears and pushes aside any thoughts of how bad things have been on this side of the verse she's now a part of. "I need your help getting back… to my verse."

"Your 'verse'." Cuthbert repeats, grinning. "Why would you want to go back?"

"Hey!" Dean moves closer to Diana, gun in hand. "You either have a way to help or not. Which is it?"

Cuthbert takes a long look at them; he can already see that the girl and the Hunter are the same. How… is what has him curious. But its not enough to get involved.

"No."

Diana glances at Dean before turning her attention again on Cuthbert. "…no?"

"No." he repeats.
