Cynthia explored Alicante for the whole duration of the day, not bothering with Jonathan at all. Whatever he was up to, whatever he was doing, she didn't really care. The sheer cheek of him to suggest this stay basically meant their relationship didn't exist. Cynthia had come to terms with pretending not to be in love with him for the stay, but this was too much. The bastard. Fine, if he wanted to be that way, she was going to deliberately hook up with some dashing Shadowhunter and see if it was possible for him to get jealous.

And it was the next day that that chance came.

Cynthia had a habit of wandering around the city with her camera primed. The place was utterly beautiful and gorgeous, like her most wildest of dreams. A city full of Shadowhunters here for the Accords.

She stood in Angel Square with her camera before her eyes, summery dress fluttering a little and taking a photo of the Accords Hall. It was shimmering and beautiful.

Cynthia lowered the camera now and gazed at the photo she'd taken. The Hall gazed back at her, a memento of her visit to the City of Glass. But she frowned as she gazed at the photo, cocking her head a little- why did that figure that was walking towards the Penhallows area so familiar?

And then she realized.

It was with a wide grin that she walked back to the house and pushed the door open, ignoring Jonathan who was sat upon the sofa. Her eyes were fixed upon the golden haired boy whose eyes widened in pleasant surprise at the sight of her.

Cynthia beamed and threw herself at him, wrapping her arms around him and hugging the boy tight, laughing out "By the Angel, I missed you Jace."

He chuckled and patted her back, telling her "I missed you too."

Cynthia was staring at Jonathan as he sat upon the sofa, his eyes narrowed the slightest fraction. Deadly almost.

A dark and mocking smirk spread across Cynthia's face as she continued to hug the angel boy, directed right at the demon one.

If Jonathan hadn't hated Jace before, he loathed him with a passion now.

"Bear with me just one moment." Jace told Cynthia as she let him go. "I need a word with the vampire."

Cynthia cocked a brow and caught sight of Simon, laughing out "First you were the mundane, now you're the vampire? You don't have much luck, do you Simon?"

He grimaced and nodded "I know what you mean. And thank you."

"What for?"

"For calling me Simon. You're one of the rare few."

Cynthia smiled sweetly at that, cocking her head a little "Well you're adorable, why would I pick on you?"

Simon flushed deeply at that, making Cynthia feel rather smug.

Everyone trickled from the room eventually, leaving Cynthia and Jonathan alone. The demon boy snorted as soon as they were alone, telling her "Don't you move fast?"

"Well, you made it clear nothing matters while we're here, so why are you bothered?"

"I'm not bothered. But… Jace? Really?"

Cynthia smiled sweetly once more, telling him with a laugh "Show me some jealously demon boy and I won't-"

"Show jealously? Why would I be jealous? Be a whore if you want, I don't care. You'll end up literally crawling back when you need my blood." He grinned and Cynthia scoffed. "So high and mighty, aren't you?"

"Fuck you."

"Be my guest sweetheart."

There were footsteps on the stairs and Jace called out "Cyn? Can we talk?"

She blew the demon boy a kiss and walked up the narrow stairs. She passed Simon on the stairs who walked past her, almost avoiding her eyes. She laughed internally at that- silly vampire fancied her. "Can we talk or just… something?" Jace asked her at the top, and Cynthia nodded, walking inside the room. "Of course" she assured him.

Jace sighed as he closed the door behind them, just saying "How are you Cyn?"

"Rather good. You, on the other hand, seem stressed."

He shrugged and nodded. "You try loving a girl, then finding out she's your sister."

Cynthia sighed internally- if only she could tell him. Jace stood before her and rested his forehead against her own, muttering out "How's your love life?"

"Nonexistent. My boyfriend… dumped me you could say."

"He had a good thing and lost it. The fool."

Cynthia laughed lightly at that, looking up as the boy took her face into his hands, sighing out "I need distracting. Help me?"

There was a pause and Cynthia went through the options in her head. But there was only one really… he needed distracting, and so did she. Had she have been kinder, she would have told him to accompany her around Alicante, taking more photos. But no, it was revenge on Jonathan that also creeped into her train of thought. "Gladly" she breathed out, grabbing the front of his shirt and yanking him to her, crashing her lips to his own.

It hadn't been the type of distraction Jace had meant, but he wasn't complaining as he kissed her hungrily back, allowing the girl to push him backwards until he was pressed against the closed door, their hands roving the others body freely.

Cynthia pulled away, her breathing a little heavy as she asked, gazing into the boys aureate eyes "That enough of a distraction, or do you want more?"

She could see him thinking almost as his hands held her waist, glancing down for a moment before he met her eyes again, his lips twitching into a devilish grin as he just tugged her closer, Cynthia letting out a low groan as his lips found her neck, letting her head tilt back and hands tug at the bottom of his shirt, breaking his trail of kisses as she tore his shirt off over his head, throwing it onto the floor and running a hand up his toned chest.

There was a pause in which it seemed time almost froze and Cynthia's eyes never left the golden ones as she was forced backwards until she fell onto the bed, staring up at the ceiling as she felt her dress being unzipped at the side and tugged slowly down along with her panties.

"You never came to visit me last time." Jace muttered out as he kissed up the girls' bare stomach, each time his lips came into contact with her skin, Cynthia groaned lightly and let her head tip backwards a fraction. Every kiss felt like a blast of pleasurable fire. She raised a hand and wound her fingers into his golden locks, replying breathlessly with "You actually noticed?"

"I always notice" he whispered into her neck, kissing at it hungrily while Cynthia's free hand tugged his belt open and tossed it aside, admitting to him "After this boyfriend being a dick, I wished for a distraction like this."

"Well we've both got one." Jace replied against her collarbone. Cynthia stared up at the ceiling once more as she popped open the button of his jeans open and tugged the zipper down, letting both her hands slip down under the boy and tug them down along with his boxers, flipping them over with ease and seating herself atop him with a devilish grin, letting her long honey blonde hair hang and frame her face as she leaned down until her lips touched his own, moaning audibly against his lips as his hands slid up her sides and to her back where her bra was swiftly unhooked, a moment later cast aside.

Cynthia's lips left his own now and trailed down his chest a short way with her hands catching his own, straightening up.

It hit her as she gazed down at him, squeezing his hands in her own and meeting those hunger filled golden eyes that this was the boy she had probably been destined to be with if Valentine hadn't split them up. It would have been her and Jace in that mansion, not her and Jonathan in the cottage. Cynthia laughed internally at the idea of calling this whole thing off, because what would piss Jonathan off more than finding out she'd slept with Jace? It was the ultimate revenge, and something Cynthia had actually wanted to do for a while. She loved Jace. No matter what happened, they always seemed to find their paths crossing again. Maybe she was just using him for revenge, but Cynthia didn't care. He wanted a distraction from Clary, to stop himself loving her probably, and she wanted revenge. They were both using each other in one way or another, but there was a deep seated connection between them that had never faded away.

"You can still back out." Cynthia murmured out as she leaned down and brushed her lips to his own once more, freeing up a hand to brush the stray strands of his tousled golden hair from his eyes that seemed to be fixed solely and utterly on her. He wasn't going to answer. He wasn't going to back out, and she knew it.

Well neither would she.

-LightInYourNightmare-

Jonathan noticed Cynthia's absence and asked the Lightwood girl where she was. She frowned and looked around, getting to her feet and went on the hunt for her. When she got to the upstairs level and tried a door, finding it locked, she just went "Ah. Oh." as she listened at the door and backed away, going downstairs and took her seat once more, wrinkling up her nose.

"Well?" Jonathan asked and Isabelle just went "She's upstairs Sebastian."

"In her room?" he inquired, raising his cup of tea to his lips. Isabelle nodded, raising her own drink to her lips, simply saying "She and Jace. I think they're having sex."

Jonathan choked on his tea at that, a coughing fit escaping him as he exploded with "What?"

"I know! But at least Jace is attempting to move on from Clary. And this is Cynthia. She's good to him and always been there for him. He missed her so so much when he was younger and-" her eyes widened and she hurriedly muttered out "Don't tell him I said that."

"My lips are sealed" Jonathan lied, setting his cup down as carefully as he could, his hands balling into fists in his lap as the anger and rage coursed through him.

He didn't think it possible that he could hate Jace more than he already did… but he truly did now.

The demon boy wanted to stab him right in his smarmy face for ever having looked upon Cynthia or touched her.

Jealously. Pure and utter jealousy.

Congratulations he thought sarcastically you've made me feel jealous, Cynthia.
