A/N: This is actually a story on its way. I just don't know if it's a fanfiction or an original yet.

Nate could remember many firsts when it came to his life with Sophie Devereaux. He remembered the first time he saw her, in that red dress with her hair flowing back in the wind as her chocolate eyes looked back in time to make sure he wasn't close to catching her that day in Prague. He remembered the day they actually met, a day of sweltering heat where she seemed to be the only person unaffected by the stuffy air and he learned her fake name. He even remembered the look on her face the first time he saved her life, and the three hour tirade she had when he simply pretended nothing happened and he somehow ended up with her helping him on his very next job though he was dead positive he never asked her. But the most important first was the day he discovered she was a fairy.

He had theories of Ms. Devereaux's true nature for years. He constantly entertained the thought that she was a goddess in disguise or a siren meant to lure him to his death who never quite got that far. A woodland nymph was on the top of that list for years because he could almost swear the trees were moving to protect her in that forest in Burgundy. He thought she might have been a demigod at some point during their adventure in Moscow. Throughout their history it was mostly Greek or Roman mythology that crawled through his mind. He never expected her culture to date back to the Vikings and belong to the Scots and the Irish. He never expected her to be a member of the fae.

Her English accent should have been enough to clue him in; it was a very purposeful hint. She always seemed to be very careful when in Glasgow, Dublin, Kilkenny, Tallow, Broadway and all the other places Ireland seemed to offer them. In Scotland and Norway she was practically a national treasure the way she would constantly walk the streets as if she could never be harmed. They certainly didn't try too hard to catch either; she hadn't exactly committed any crimes there. He clued in in Switzerland when a little girl of seven ran up to her and demanded to be taken to the sea so she could be a dark one too. She definitely had the black eyes, black hair and dark skin of a Selkie. He was almost sold on the idea that she was one of the daughters of the sea, somebody whose true form is a seal. It would be very easy for her to use one of her warehouse hideouts as a place to slip out of her skin and store it away where no man could steal it from her and effectively imprison her as his wife.

Then the job came where she saved his life. How did she do that? Well, she made a whole bunch of birds attack the men with guns. Then she proceeded to use the water to heal his mortal wound. She even urged the moss to grow and make him a perfectly cushioned bed while he recuperated. Unfortunately for her, she thought he was unconscious, dazed and confused.

She was gone when he finally woke up in his hotel room later that afternoon. His nymph theory started to appear far more accurate than he expected. So he did his research and discovered something he wasn't expecting. He ran to catch her again, and to thank her for her work. A job came up and she was the perp. She ran and he chased. In fact, he chased her to Spain where she was working on a little job.

She was conning some rich man. It doesn't matter who, she never finished the job. Nate remembered the way she looked as she was conning the man. He could tell just by looking at him that her mark wasn't normal. His eyes were gold permanently and his cologne constantly reeked of sulfur. He was a demon. She was conning a demon with absolutely no fear and a firm smile on her face. When he finally got a moment to talk to her he was almost stunned into silence. Her eyes weren't the usual chocolate brown color they belonged to. No, they were glowing an earthly green and she seemed to have no idea the scent she was giving off. It was safe and smelled of the earth, covering the sulfuric smell perfectly.

"What do you want, Nate?" She asked, her eyes changing to a darker green at his appearance.

"You're a fairy," he said and that's all that needed to be spoken.

The grifter's eyes snapped back to brown and her head shot around with fear blazing in her eyes. She gripped his lapels with such intensity fear shot through him. They found their way to a closet and she turned on the light. Her eyes flashed bright green again before their conversation began.

"What do you want?" She asked, reaching into her purse in a very pointed gesture.

"Not a bribe, that's for sure," he replied, pulling her arms down with worry, "That's not why I'm here."

"You're going to report me," she said, despair vibrating through her voice, "How did you figure it out?"

"You saved my life." He grabbed her chin and forced her to look him directly in the eyes. "I thought you were a nymph until I did some research. Nymphs can only control one element of nature. You can control all of them. Plus, your eyes glowed green just now. You're a member of the fae, a fairy. A very powerful fairy, I might add."

The smile on her face tugged at his heart somehow in ways Maggie never could. There was mischief shining in her eyes and it was almost like they were playing the same old game. But Nate could sense danger lurking under the surface. He knew there was something bad lurking behind that smile.

"I always knew you were brilliant," she said, slowly raising her hand to caress his cheek, "I was hoping not that brilliant though."

Panic started to rise in the mastermind's chest. He grabbed her hand and flinched at the heat that was radiating from it. He grabbed her shoulder and pushed her back so their eyes were meeting once again.

"I have a wife and son, Sophie," he growled.

She laughed. The sound was hollow and mirthless. It even had a ring of sadness.

"I'm not going to kill you," she said, "I don't kill. It's one of the many fae rules I actually follow. I'm just going to do some harmless brain alterations."

He grabbed her hand and forced her into the wall. Then he used his body to pin her there and created the illusion of something different. He even placed a stray hair behind her ear just to stick with it.

"You're not going to wipe my memory of you," he said.

"No," she smiled and shook her head, "Just this moment and every moment of your discovery. You'll thank me for it later."

His grip on her hand tightens. Her eyes widen with surprise and turn green with anger. He smiled and continues to shake his head.

"Your secret is safe with me, Soph. Please… don't take them away."

"I can't trust you, Nate." There was pain in her eyes, forcing them to a more violet green. She looked so saddened by what she was about to do that Nate could have sworn his heart stopped. For just one moment he was allowed inside the mind of Sophie Devereaux; all the secrets, all the lies. No wonder her list of friends was so easily made on a couple of fingers.

He grabbed her hand and smiled. Then he cupped her cheek and forced her to see something no one else could ever know of.

"I swore an oath to the Fae Coven a long time ago that I would never give away the true identity of any of its members," he said, "and I swear on the royal family to uphold that promise."

The smile that cracked upon her face was that of a child on Christmas morning. She even had a few tears of happiness sparkling in her eyes. He'd never been so relieved to see her beautiful brown orbs return.

"You're not human either," she said.

He put a finger to his lips and that was the end of it.
