"What the hell are you?"

"Get out of the way, little girl." Doctor Osborne swatted Emily aside, with no more effort than if she were a bug. Her nose began to bleed freely as she hit the wall and sank down to the floor, in shock. Doctor Lyons rubbed her hands together, sizing up Samuel.

"Surely you knew we would find you."

Samuel backed away, pulling at the plastic strip that bound his wrists. His look was a mixture of scared and angry.

"Time to say goodbye and die, freak." Doctor Osborne sneered, raising his hand.

"If you insist." A single shot was fired, echoing in the small room. Emily watched in horror as he crumpled, bleeding. Emily looked around herself wildly, not believing that she could feel any more shock.

"Doctor STEINHARDT?!" Perhaps she was wrong.

"'Evening, Doc." Lyons lunged for him. He sidestepped and rapped her sharply on the head with the butt of his shotgun.

"What the HELL?!"

Robbie Steinhardt grabbed her wrist and pulled her to her feet. "They won't stay down for long. Get out of here!"

"You just SHOT my SUPERIORS with a GUN! Like HELL I'm going to do what you say! What's going on?"

On the floor, Osborne's hand began to twitch. "Questions later. Run now."

Steinhardt barricaded the door behind them as Emily slipped the cuffs from Samuel's wrists. She angrily turned back to the other doctor. "You have two minutes to start explaining yourself before I call this in!" She threatened.

"Two minutes." He said. "Not much time to work with."

"Enough if you know what you have to do. If you don't talk fast, you'll have even less to work with."

Steinhardt shrugged. "Sounds fair." He took hold of the sleeve of her coat and pulled her out of earshot of Samuel, who was still rubbing his wrists.

"Now don't talk and don't make a sound. Just blow this joint."

"What? Why?"

"You're not going to believe me."

"Just. Tell. Me."

"Fine." He shrugged, looking frustrated. "Fine. Brutal truth? Your little friend Sammy is possessed."

"Uh huh." Emily said, unconvinced. "Do you see Jesus? Does he tell you to do things?" Clearly all the lunatics weren't behind bars.

"I'm serious, lady! Listen, I suppose Osborne and Lyons tried to tear you apart 'cause they'd had a hard day, huh?"

"Well-" Emily stepped back. "Samuel, I think we should go."

"Don't-"

"Emily is right. I should go." And he turned to them. His eyes shimmered a pale, cold blue.

"Oh, my God." Emily gasped.

"Not quite." Samuel said. "Actually, pretty far from it." Steinhardt swung up the gun, but with a glance from Samuel, it flew out of his hands and sailed down the corridor. "I should have known." He said. "I should have known wherever this body went, you wouldn't be that far behind."

Steinhardt coughed, his face turning red. Emily glanced at him as he raised his hands to his throat, horror on his face. He sank to his knees.

"You're killing him!" She shouted, kneeling by Robbie's side.

"That's the general idea, pet." Samuel said. "I had hoped it would not come down to this. I was really starting to like you, Emily, and so was Sam."

"If you like me, stop what you're doing! He can't die like this!"

Samuel's face twisted. "You don't understand." He said urgently. "They'll find me. That's all they'll do. They'll find me and tear me apart."

"Who? Who will find you?"

"I-" He was wavering, and Steinhardt began to breathe a little easier. Keep him talking. "No!" He shouted. "I'm not going to die because of you!"

"Is that so?"

Sam spun as the water arched through the air. He gave a shout of shocked outrage as it hit his flesh and began to steam.

"Christo, you mother." The woman shouted.

Suddenly Steinhardt could breathe again. As he gulped in buckets of air, Emily just stared as Samuel and Captain Wandell began to circle each other.

"You should have stayed away, hunter." Samuel said.

"Yeah, well. Felt like I was missing out on a party."

Samuel lunged for Captain Wandell. At that moment, Doctor Steinhardt, who seemed to be running on adrenaline, sprung to his feet. Seizing one of the plastic folding chairs, he swung it over his head and smashed it into the back of Samuel's skull.

"I can't believe you just-" Emily was horrified.

"No time right now." Sam's arm jerked on the floor. "He'll be up and about in no time. Come on. You too, Kamikaze Barbie." He hustled them out the door.

"What now, genius?" The captain shouted. "What the HELL do we do?"

"I have a… well, I have sort of a plan!"

"Fantastic! Mr Wizard has a plan!"

"Ease up, GI Jane. I'm doing the best I can!"

Steinhardt lead them through the darkened corridors. Emily recognised with a shudder of revulsion the age-old instruments, out on display in their cases. He was leading them into the old wing, the area that had been converted into a museum to glorify the days when the treatment was as ineffective as it was brutal.

Steinhardt spun on the heel of his boot. It was only then that Emily noticed that he was wearing hiking boots and jeans under his long white coat.

"Who are you?" She whispered. "Who are you both?"

"It's complicated." The pair of them said at the same time.

The door blew back off its hinges. "You couldn't have just left well enough alone, could you?" Samuel, the thing in Samuel said. "They'll kill me. They've found me only because you interfered."

"No." Emily backed away, behind Captain Wandell and Doctor Steinhardt. Steinhardt flung out an arm to make sure she was backed into the shadows. "Samuel, please."

He stepped forward. "Emily." He said. "I'm sorry. I really am." Then he stopped. Looked up to the darkened ceiling. Scowled. "You insignificant, pathetic little man. You think you can hold me in something as meagre as the Key? I'll not be caught out twice."

Steinhardt shrugged, looking sheepish. "Worth a try." He mumbled. "But-"

"But what?"

"Have you looked down yet?"

There, scratched into the stone, was a circle, a circle that encompassed Samuel but excluded Doctor Steinhardt, Captain Wandell and Emily.

"No." Samuel breathed.

"Gee, old buddy. I'd say that's definitely caught twice."

Steinhardt and the captain tied Samuel to a nearby chair.

"Who are you?" Emily asked again. She had long passed denial, and was now in the phase of grim acceptance. "Tell me."

"Who I told you." The captain said. "Sally Wandell, captain. US Army."

"But this – what you do-"

"Big fan of Buffy and Rambo."

Steinhardt snorted. "And who are you?" Emily demanded. "Your name's not Robbie. Was there anything you told me that was actually true?"

"Not really." He confessed. "Not a doctor. Honestly, I never even sat my finishing exams."

"What's your name?"

"Dean." He said finally. "Dean Winchester."

"You're-"

"Yes."

"The-"

"Yeah."

"But­-"

"Yep." He ran his fingers through his hair. Glanced at Captain Wandell. "Gonna bring me in?"

"Demon in here. Two downstairs and however many more on the scent." She looked almost pained as she said it. "No."

"Thanks."

"Winchester?"

"Yeah?"

"Tomorrow it's business as usual."

As the other two watched, she pulled a small notepad out of another pocket in her cargos. "Mind if I do the honours?"

"Be my guest."

Samuel had been quiet until this moment. Now he looked up, hate in his eyes. "You think this is finished? As soon as they see that I'm gone, they'll slaughter each person in this godforsaken place."

"Sorry, pal." Dean scowled. "If they really want you that badly, they'll chase you all the way back to Hell." He glanced at Wandell. Gave her the smallest nod of the head. She began to read.

"Deus, et Pater Domini nostri Jesu Christi, invoco nomen sanctum tuum, et clementiam tuam supplex exposco-"

It was an exorcism. Not a fake-puke, head spinning 360 kind action, but a proper, honest-to-God exorcism. Emily didn't know what to do beside get out of the way and let Wandell and Winchester let loose with their mojo. And she decided that she had some major issues to work through.

Samuel was beginning to flinch, as though he was being pricked with hundreds of invisible pins.

"You could get out of him now." Dean said as his brother gritted his teeth. "Save us all the trouble. We all go home early."

"Per eumdem Dominium. Amen-"

"You don't understand." His knuckles were white as he gripped the arms of the chair. "No idea."

"Oh, I have more of an idea than you think."

"Exorcizo te, immundissime spiritus, omni incursio adversarii-"

He was beginning to shake. "You know nothing."

"Really? I know your little demon buddies aren't that happy with you right now-"

"Exi ergo, transgressor. Exi, seductor, plene omni-"

"'Cause you go ahead and find a doorway outta Hell and you don't tell any of 'em. You up and get a one-way ticket out of Dodge. You were never trapped in Glamis Castle at all. You were using the nexus of supernatural power generated by the ghosts as cover."

"Not bad." The demon Dantalion hissed. "Did you figure that out yourself or did someone have to tell you? I can help you. I can tell you things no one else knows. Show you places no one else sees. Just let me stay here. In this body."

"No chance."

"Reus es Filio ejus Jesu Christo Domino nostro-"

"Why here, then?" The demon said. "Let me tell you. All these humans. All these messed-up psyches. It was the perfect cover."

"And you would have gotten away with it too if it wasn't for us meddling kids."

"Laugh, but it scares you. How long before you end up like one of these people? How long before there's no meaning to anything anymore? How long before you're empty? They're still waiting, you know."

Dean didn't have any retort for that.

"-et crucifigere praesumpsisti-"

"They'll keep you alive just to hear you scream." The eyes were shining with pain. "Piece of advice, Deano. You don't have to sell your soul to end up in Hell. Show 'em all and live."

"What are you talking about?"

"Deus, per omina saecula saeculorium. Amen!"

Grinning widely, he threw back his head. The cloud erupted out of Sam's limp body. It billowed around him for a moment or two before rolling up on itself and vanishing.

All was silent for a long moment.

"I wonder how many people heard that?" Emily asked shakily.

"Enough." The captain said. She nodded her head at the groaning Sam. "Get him out of here."

Dean just looked at her.

"Move it, while I'm still in a good mood." She snapped.
