WARNING.

This is not a happy, lovey dovey fluffly fanfic. I'm writing this to challenge myself and I want to make it as realistic as possible. So there will be angst, and anger and conflict and hatred and feels, as you would expect when dealing with a demon ya know. I don't even know where exactly I'm going with this, it's probably not even a romance despite the pairing, it's just characters interacting and stuff. So give it a try, if you want :)

This sort of just happened. I've been wanting to have a go at writing something with a more serious undertone for a while now, and this idea has been whirring around in my head for too long.

I have literally no idea what will come of this, it's simply a one shot but if you liked it and think I should write more, I was thinking about making it into a serious of one shots. Be sure to let me know! Thank you!

The first time Clara Oswald met Hell's grand torturer she was majorly unprepared for what awaited her.

Necessary, they had said. This was all necessary, no matter how cruel or callous it appeared.

"They're angels, Clara, proper angels, not the statues who wait for you to blink to strike," The Doctor had assured her firmly, a cold storm brewing in his eyes as if he was trying to convince himself as well as his companion and carer. "If they say that this is God's will, we have to leave them to it."

Clara had attempted to protest, her compassionate heart getting in the way of what was apparently just and righteous. She couldn't help but wish the Tardis had not landed them in the midst of a place where tall, flannel-wearing men who called themselves hunters and icy-eyed people who proclaimed to be angels were in the middle of a barbaric interrogation. One the Doctor just had to accidentally get himself involved in.

"This isn't right," She had whispered under her breath, her voice soft as the breeze as she was led through the heavy metal door into a room which she felt unbearably sick at the thought of stepping into.

A large, pentagon-like structure, surrounded by strange markings and symbols on the floor in a neat circle. A Devil's Trap, they had informed her. The strongest known to the angels in question. Clara would never forget it, would never forget how foreboding it looked. She knew she should have turned back there and then, but when she caught sight of the man chained to the inhuman structure that restrained him so securely, she knew it was too late.

The slow building, sinister laughter that started soft then rose to a louder, more mocking tone froze her in place. As the man- The demon, as the angels had so kindly informed her that yes, they did in fact exist- Slowly raised his head at the intrusion of the newcomers, his eyes seemed to shift and change. Clara watched, transfixed and paralysed with fear as the demons eyes rolled and became a terrifying, translucent white. If Clara hadn't known better, she would have almost assumed he was sightless, but she was aware that this demon saw a lot more than what was right in front of him.

His cracked lips grew into a slow smile, blood dripping from his mouth. Pain, Clara thought, the one small but meaningful word filling her very pores and swirling around in her mind. The pain they must be causing him. His shirt was drenched with so much blood that it made Clara feel nauseous. A result of the barbaric torture that the Doctor had been informed they were inflicting on the demon to find out who was murdering the angels in their garrison.

The Doctor had told her she didn't have to see the effects the torture had had on the demon. He told her that she could lay low, wait until all of this was over and not have to go near the man. The eccentric Time Lord wanted to see this through, of course he did. Clara wouldn't have expected anything else of him. He was like a dog with a bone when it came to walking in on these things. Never one to leave unfinished business, but always one to find trouble.

But the Doctor wasn't here right now. Consulting with the angel who Clara now knew as Castiel, he was outside, trying to concoct a more effective plan. The torture wasn't working, they had said.

Which was why they had called him in. Dean. The man who had reluctantly allowed her access to this chamber. He was the demon's best pupil, apparently. The only one who had any chance of breaking him. Clara didn't quite yet grasp the concept of what that meant.

But she was here, now. After hours of indignant protest and angry words fired like bullets, she was finally permitted to see for herself what the Winchesters and the angels were working on.

His name was Alastair. That much she knew. But as she looked at him now, all she could see was evil personified.

He was a master of torture in Hell, that was all the information she had been given. It was enough to condemn him to this fate, as they saw it, though Clara couldn't quite wrap her head around the concept that anyone could actually deserve to endure so much torture and pain, no matter what they had done or were capable of. Still, this man was definitely no angel.

"Picasso with a razor…" She breathed fearfully without even realising she had muttered the words she had been told earlier aloud. She had spoken so quietly that she wasn't even sure Dean heard, but Alastair perked up, a sly glint in his bright white eyes. Clara had still managed to keep a good distance from him, so she assumed demons must have some sort of supersonic hearing. She gulped audibly, realising with a start that he had probably heard that too. Her suspicions were confirmed when a smirk danced around Alastair's lips.

"What a pretty little toy."

His voice cut at her like blade and sent a shiver down her spine. She hardly dared to breathe, suddenly wanting nothing more than to leave, to leave this room, this town, this country. To hop in the Tardis, shutting the door with a click of her fingers and to fly far, far away, her Time Lord friend in tow. But she was here now. Her choice, her decision. Possibly her mistake. Clara Oswald straightened her trembling figure, standing as tall as she possibly could and tried her best not to look as frightened as she felt. He's bound, completely powerless. He can't hurt you.

Alastair blinked slowly, the edges of his lips still curved upwards sadistically and when he opened his eyes again, they had returned to a relatively normal blue. Clara stifled a gasp at the unexpected transition.

"Is it for me?" The demon continued on from his previous statement, his words sending a chill colder than the most frozen winter through Clara, a slow river of ice streaming through her veins and welling up in her soul.

"Back off, Alastair," Dean growled, but Clara hardly heard him. Her stoic gaze was fixed on Alastair, she was afraid to look away.

"Would if I could," Alastair replied lazily, his voice a perpetual sneer as his eyes drifted to the chains that bound him tightly and returned to rest on Clara.

"Come on, Clara, we're leaving," Dean turned for the exit, and Clara's hazy mind finally gave the order to her legs to begin working again. The unlocked themselves from their frozen state and she took a cautious step backwards, away from the demon.

"My, my, so eager to leave," Alastair drawled, and Clara felt as if she wanted to run, to run so fast and so far away from this dangerous entity that could threaten her with a simple glare. "Something I said?"

"Clara."

Dean's voice rang out in warning as Clara realised she had halted in her tracks again, still unable to take her eyes off Alastair.

"I didn't even catch your name," The demon purred as Clara took another shaky step back. She swallowed hard, taking in his mocking eyes that she was hastily learning to distrust.

"All you need to know is that I am not your plaything," Clara finally spat in a hiss, her own boldness surprisingly her for a moment as she defied the demon's reference from earlier.

She whipped around and made to leave, but not before she caught the expression on Alastair's face.

The demon almost looked impressed.

Oh jeez I hope I kept everyone in character!

So as I said above, this is a one shot but I'm thinking of expanding it if you guys like it, so let me know what you think I should do :) Thanks my fandom friends!
