"Just what are you doing Cynthia?"

"Meditating."

"Looks more like-"

"You're ruining my concentration. Get lost."

Jonathan cocked a brow as the young woman sat beneath the cherry tree in the garden, her eyes closed. He folded his arms and nudged her with a foot, making her snarl out "Go away."

"But annoying you is so much fun."

Cynthia let her eyes open and narrow, grabbing his ankle and twisting it so he fell to the ground in a heap, smiling sweetly as she closed her eyes once more. "See you later Jonathan."

Jonathan snarled and pounced, grabbing her throat and pressing her head to the floor, the girl opening her eyes to gaze lazily up into his own midnight ones "Cynthia, you may have our father wrapped around your little finger, but I know differently."

With a sigh, Cynthia rolled her eyes and raised her hands to grab her blade that was sat comfortably in her pocket. She pressed it to Jonathan's side and smiled sweetly "Get off me right now, or I'll drive this into your side. Hmm, maybe then castrate you."

Jonathan chuckled quietly and got off her, kicking the blade away and watching the young woman climb to her feet.

"Did you love angel boy?"

"Shut up. You don't talk about him."

"Awwh, little Cynthy had a wittle crushy wushy on-" Jonathan stopped dead as Cynthia punched him in the nose, grabbing his throat and slamming him into the tree with her eyes dangerous. "You can't talk about him. And if you do, I will cut your damn tongue out."

He was gazing at her in amusement, shrugging a little as he replied "Anger issues, Cynthy. You have them." She let him go and turned away, turning back only once to throw the dagger she always, always kept safe in her back pocket. It embedded itself into the tree, missing Jonathan's ear by a mere centimeter on purpose.

"Your father would like to see you." Sarah the maid told Cynthia hastily as she stepped into the house. The girl blinked, but then nodded "Thank you Sarah" she replied, not smiling.

Sarah felt uneasy around Jonathan, and even more so around Cynthia. When she'd first come here, she'd been soft. Now? She was a terrifying presence to be in. She had this aura about her that seemed to radiate something sinister. Valentine had truly outdone himself.

Cynthia knocked on the study door and heard the familiar voice call "Come in." She opened the door and stepped inside, smiling at her adoptive father as she closed it behind her, walking forwards until she was stood before the man. He'd aged so much since she'd first seen him at the age of four. More lined it seemed and older looking. But he was still the man she loved and hated with equal measure.

"Good afternoon Cynthia." He said calmly, setting his pen down. Cynthia took the seat before him and cocked her head a little "You wanted to see me?"

"Indeed I did." He cleared his throat "You are almost eighteen. It's time you know… what you are. What both you and Jonathan are."

Cynthia frowned, shaking her head a little "I don't understand-?"

"Jonathan has grown up knowing what he was. But you my dear, I had to be sure of you."

"Be sure of me?"

"Of where your heart was. You were such a little timid thing when you joined us Cynthia, and I can confidently say you've grown up into a beautiful young woman who shows more than a little promise." A pause. "I wasn't lying when I said you were special. You are, truly. Demon blood runs in your veins Cynthia."

Of all things, she wasn't expecting that. Cynthia blinked a few times in surprise, blurting out "I'm a demon-?"

"No no. You just have the blood of one. Why do you think you're so much stronger and faster than a normal Shadowhunter, Cynthia my dear?"

In her head, she was adding up the evidence, laughing out "And Jonathan?"

"Jonathan was born with demon blood. You were given it from when you were four."

It hit her. "That medicine that made me ill…"

"Are you angry at me Cynthia?"

Cynthia knew she should have been, but she wasn't. She felt fine, in fact, she'd never been better. Why should she be angry? He'd… given her a gift. He'd taken her in, raised her as his own daughter, doted on her and made her even better. She could never hate him.

He was her father.

She smiled and shook her head "I'm thankful."

Valentine wasn't expecting her to be quite so placid and obedient like this, but he wasn't complaining. "You are everything I could ever ask for Cynthia, truly. It's my honor to give it to you."

She beamed and folded her arms upon the table, shaking her head a little "Don't you need help with something? You know I'm more than capable."

"I know my dear. But not just yet." But then a thought crossed his mind and he chuckled out "I do have… one request though."

"Oh?"

"My son. I want you to make my son think you're in love with him."

Cynthia had a look of utter disgust upon her face as she spluttered out "I'm sorry, but… I can't even…" she swallowed hard. "That is impossible. I can't stand him. Why would you want this?"

Valentine sighed lightly, keeping his gaze fixed upon the young womans. Her face was a mixture of horror and curiosity. "Jonathan has limited emotions, you see. I want to know everything he is capable of. This isn't something I am taking lightly, Cynthia. I am only asking this of you because I know what you are capable of. You are the only person I would ever trust to do something like this. Or at least, attempt it."

"I am not kissing him. I refuse point blank to kiss him."

"Cynthia."

She started to whine now "But I… by the Angel I could never kiss that beast."

Valentine chuckled, getting to his feet and tucking away a sheaf of paper into the draw. "You offered to help me, you can do this."

"There has to be something else. Please."

"That will be all. Good day Cynthia." He said with ringing finality and she just stared at him. She watched him cock a brow, then she cleared her throat, next to storming out of the room.

-LightInYourNightmare-

Cynthia paced her bedroom with a feeling of intense frustration. He was expecting her to seduce Jonathan? Without him realizing something was up? It was impossible. The idea of pretending to be infatuated with Jonathan was making her feel sick.

But she had her orders. And no matter what, she stuck to them. No matter how much she hated them.

With a quiet groan, she collapsed onto her bed, staring up at the ceiling. She was a warrior, destined for greatness her father had told her, and she believed him. Jonathan was always making snide little comments to her that she was the favorite of them both, and she agreed. She knew she was, whether she liked it or not.

It was comfortable here and she had no intention of leaving or changing this lifestyle. She was a dark princess, just like he'd promised her.

Cynthia curled up into a ball now, letting her eyes close. It felt like she'd grown up too fast, her childhood rushed and a total mess. It was made up of blood, training, more blood and even more training. And both her Jonathan's. She shoved all thought of that first one away, suddenly feeling lonely. There was no one to talk to now that her golden haired Jonathan was gone.

She was all alone really. And that meant she had nothing to lose. That she ran headlong into whatever her adoptive father threw at her.

Cynthia pulled the covers over herself and sighed lightly- what use was all this power when she had no one to share it with or have fun at least?

The door opened and Cynthia sat up, staring at Jonathan as he strolled into the room and over to where she kept her weapons in the corner, grabbing one of them. "Now this is mine." He growled, looking over to her. Cynthia saw the Morgenstern blade in his hand and scowled "Well your father gave it to me."

"It's mine. I am the heir to the Morgenstern title, which means this blade belongs to me. You have no Morgenstern blood. How dare you think you can keep this blade?"

This is what I have to attempt to seduce? Cynthia thought in disgust as she watched him run a finger up the edge of the blade, a grin on his face.

It wasn't that Jonathan wasn't good looking, because he was. Cynthia knew other girls her age would squabble and fight to date him. He was tall with shadowy eyes and white blond hair that was carelessly all over the place. There was a dark beauty about him that no one else could ever achieve.

He was gorgeous on the outside, but inside? He truly was a demon.

"Fine take it. You're right."

Jonathan paused at that, cocking a brow at her. "You're not mad?"

"Why would I be? You were right."

He was staring at her as if she'd grown antlers. Cynthia waved a hand, sighing out "I'm just sick of arguing with you. Can't we just start again or something?"

"Who are you and what have you done with Cynthia Darkstone?" Jonathan smirked out, flicking the hilt of the blade. Cynthia rolled her eyes and the young man raised the blade, pointing it at her "I do not trust you bitch."

"Your loss."

"I'm sick of this place. Ever since you made a reappearance here, Father ignores me. What's it like being the golden girl huh? The apple of his eye?"

"Jonathan-"

"Fuck you Cynthia."

She snapped, sitting up and growling at him "I may have demon blood like you, but even he knows I'm not as fucked up as you are. You disgust me Jonathan. So yes, please leave."

Jonathan waved a hand and laughed lightly. "Yeah. You'd love that, wouldn't you? Have the place all to yourself then."

"I tried to be nice to you Jonathan, but you threw it back in my face."

"Boo hoo. Don't care. I don't kill you because my father would be extremely mad at me. You underestimate just how much he cares about you. More than me, that's for certain. You may look and act like angel, Cynthia, but you have demon blood. Just like me-" he stepped forwards and raised the blade higher so it kissed her throat "I wonder which one of us is the bigger demon, my dear Cynthy?"

Cynthia knocked the blade away, her eyes blazing "Leave. Just get out. You're just jealous that your father wishes I was his actual daughter and not have you for a son."

He flinched at that, murder in his eyes. With a quiet scoff, Jonathan turned and walked out, leaving Cynthia to sink back down upon the bed with a sigh-

She really did hate arguing with him.

Half an hour later, her door was shoved roughly open and Valentine stood there, his dark eyes angry as he strode over to Cynthia and grabbed the front of her shirt, dragging her to her feet, asking with a snarl "What did you say to Jonathan?"

"I didn't say-"

"Because he's gone. Stole my infernal ring from my desk and vanished. Did you tell him what I asked you to do?"

Cynthia knew better than to argue and fight, for she'd lose. Instead, she muttered out "I told him to leave…" Valentine let her go where her knees buckled, crashing to the floor. She hastily got to her feet and he told her in a cold, emotionless voice "Well then. You better get going and bring him back. You lost him, so you find him."

"But he could be anywhere." Cynthia protested and the man grabbed her wrist, forcing something onto her finger with a "Now this will take you to wherever he is. A twin of the ring he stole. Don't bother coming back until you have him." He twisted the ring upon her finger and she felt herself vanish.

Cynthia blinked a few times, staring around the place she'd materialized in. She recognized it from the book of the world she had. New York. The massive park in the middle of the city, she couldn't remember what it was called. She'd look it up when she got back. Well… if she found Jonathan that was.

She looked around the park, searching for someone with white hair that would stick out a mile. But there was no one. Cynthia sighed and rolled her eyes, starting forwards-

It seemed an impossible task, looking for a demon boy in a city of concrete and glass.
