Author's Note: Now that you know the back ground you can guess I'm changing things up just abit. This story starts right after Clary and Jace kiss at the Seelie Court and our back at the Institution in Jace's room. Also I want to thanks Burning x Impossibly x Bright for helping with this story idea and for beting it!

Disclamer: I do not own the Mortal Instrument series or Vampire Diaries they belong to the lovely writer's Cassandra Clare and L.J Smith. Also the first little bit is from the City of Ash.

It wasn't her fault that she cared about Simon. They had been best friend since they were little, of course she would worry about him, but Jace's attitude was getting on her nerves. Clary raked her still-dank hair out of her eyes. Her clothes itched where they clung to her skin, and she suspected she smelled like the bottom of a pond, and she couldn't stop seeing Simon's face when he'd looked at her in the Seelie Court-as if he hated her.

"It's your fault," she said suddenly, rage gathering around her heart. "You shouldn't have kissed me like that."

Jace had been leaning against the door frame; now he stood up straight. "How should I have kissed you? Is there another way you like it?"

"No." Her hands trembled in her lap. They were cold, white, wrinkled by water. She laced her fingers together to stop the shaking. "I just don't want to be kissed by you."

"It didn't seem to me that either of us had a choice in the matter."

"That's what I don't understand!" Clary burst out. "Why did she make you kiss me? The Queen, I mean. Why force us to do- that? What pleasure could she possibly have gotten out of it?"

"You heard what the Queen said. She thought she was doing me a favour."

"That's not true."

"It is true. How many times do I have to tell you? The Fair Folk don't lie."

Clary thought of what Jace had said back at Magnus's. They'll find out whatever it is you want most in the world and give it to you- with a sting in the tail of the gift that will make you regret you ever wanted it in the first place. "Then she was wrong."

"She wasn't wrong." Jace's tone was bitter. "She saw the way I looked at you, and you at me, and she played us like the instruments we are to her."

"I don't look at you," Clary whispered.

"What?"

"I said, I don't look at you." She released the hands that had been clasped together in her lap. There were red marks where her fingers had gripped each other. "At least I try not to."

His eyes were narrowed, just a glint of gold showing through the lashes, and she remembered the first time she had seen him and how he had reminded her of a lion, golden and deadly. "Why not?"

"Why do you think?" Her words were soundless, barely a whisper.

"Then why?" His voice shook. "Why all this with Simon, why keep pushing me away, not letting me near you-''

"Because it's impossible," she said, and the last word came out as a sort of wail, despite her efforts at control. "You know that as well as I do!"

"Because you're my sister," Jace said.

She nodded without speaking.

"Possibly," Jace said. "And because of that, you've decided your old friend Simon makes a useful distraction?"

"It's not like that," she said. "I love Simon."

"Like you love Luke," said Jace. "Like you love your mother."

"No." Her voice was as cold and pointed as an icicle. "Don't tell me what I feel."

A small muscle jumped at the side of his mouth. "I don't believe you."

Clary stood up. She couldn't meet his eyes, so instead she fixed her gaze on the thin star- shaped scar on his shoulder, a memory of some old injury. This life scars and killing, Hodge had once said. You have no part in it. "Jace," she said. "Why are you doing this to me?"

"Because you're lying to me. And you're lying to yourself." Jace's eyes were blazing, and even though his hands were stuffed into his pockets, she could see that they were knotted into fists.

Something inside Clary cracked and broke, and words came pouring out. "What do you want me to tell you? The truth? The truth is that I love Simon like I should love you, and I wish he was my brother and you weren't, but I can't do anything about that and neither can you! Or do you have some ideas, since you're so goddamned smart?"

Jace sucked a breath in, and she realized he had never expected her to say what she'd just said, not in a million years. The look on his face said as much.

She scrambled to regain her composure. "Jace, I'm sorry, I didn't mean-''

"No, You're not sorry. Don't be sorry." He moved toward her, almost tripping over his feet- Jace, who never stumbled, never tripped over anything, never made an ungraceful move. His hands came up to cup her face; she felt the warmth of his fingertips, millimetres from her skin; knew she ought to pull away, but stood frozen, staring up at him. "You don't understand," he said. His voice shook. "I've never felt this way about anyone. I didn't think I could. I thought- the way I grew up- my father-''

"To love is destroy," she said numbly. "I remember."

"I thought that part of my heart was broken," he said, and there was a look on his face as he spoke as if he were surprised to hear himself saying these words, saying my heart. "Forever. But you- ''

"Jace. Don't." She reached up and covered his hand with hers, folding his fingers into her own. "It's pointless."

"That's not true." There was desperation in his voice. "If we both feel the same way-''

"It doesn't matter what we feel. There's nothing we can do." She heard her voice as if a stranger were speaking: remote, miserable. "Where would we go to be together? How could we live?"

"We could keep it a secret."

"People would find out. And I don't want to lie to my family, do you?"

His reply was bitter. "What family? The Lightwoods hate me anyways."

"No, they don't. And I can't lie to my mom and Luke. They have given me so much already. What would we say to them? This, what we want, it would be sickening to everyone we care about-''

"Sickening?" He dropped his hands from her face as if she'd pushed him away. He sounded stunned. "What we feel- what I feel- it's sickening to you?"

Clary caught her breath at the look on his face. "Maybe," she said in a whisper. "I don't know."

"Then you should have said that to begin with."

"Jace-''

But he was gone from her, his expression shut and locked like a door. It was hard to believe he'd ever looked at her another way. "I'm sorry I said anything, then." His voice was stiff, formal. "I won't be kissing you again. You can count on that."

Clary's heart did a slow, purposeless somersault as he moved away from her, plucked a towel off the top of the dresser, and headed toward the bathroom. "But- Jace, what are you doing?"

"Finishing my shower. And if you've made me run through all the hot water, I'll be very annoyed." He stepped into the bathroom, kicking the door behind him.

Clary felt her vision swirling around her; she felt like her heart had stopped beating. Why did she have to say that? She sat down on the edge of the bed; she could feel herself sinking just a bit, but she didn't care. All she could think about was what did she just do? She pushed Jace away, that's what and now he was mad at her. She held her head in her hands, trying to calm down, but it was no use, a silent tear slipped and gently rolled down her pale white cheek. Her mind was full of wandering thoughts about her and Jace, and how they felt this undeniable connection they had. Jace's suggestion kept replaying in her head over and over again. No, they just couldn't do it, it wasn't right. No siblings should feel this way, the way they do. It was wrong, but what could they do, it's not like they could turn off their emotions, their feelings for one another.

Finally, after a few minutes of thinking, Clary made her decision. Quietly she got up and headed towards Jace's window, the one that looked over the deserted street. She could see her reflection staring back at her, she was a wreck. Her damp clothes clung onto her, making her look even skinnier then she was already was. Her hair was also still damp as it flowed over her shoulders, and as she stared at her face, it was like staring at a stranger. All of the colour was drained from her face, leaving it a pale white, and her eyes were blood shot and puffy. She couldn't stand seeing her reflection anymore, so she stared out and watched as a street light started to flicker off and on. Then she noticed there were only a few people walking now. She gave a soft sigh as she leaned against the cool glass. After several seconds of collecting herself and trying to pull herself together, she headed for the door. Before she left the room, she took one last glance around Jace's room, she was going miss it...and him, but she had decided this was for the best, for both of them, even if Jace couldn't see it at the moment, it was. Soon her feet started walking again and led her towards the room that she had been staying in over the last few weeks, since her mother and Luke had gone into hiding.

She quickly packed only the essential things that she needed. Once that was done, she found a few pieces of scrap paper and starting writing letters to Isabelle, Simon and Jace. She was going to miss them so much, but it was better this way. This way she couldn't hurt anyone she cared about anymore. After Clary finished, she laid them on the bed knowing that Isabelle or Jace would find them. She picked up her bag and swung it onto her shoulder. Silently, Clary made her way past Isabelle's room, she could hear Isabelle looking for something and she was making a lot of noise, so that was useful. But as she passed Jace's room, a tear slipped out. She really was going to miss him, but this was for the best in the long run. So she kept moving until she finally reached outside. She hailed a taxi, and it slowly pulled over. She got inside and threw her bag onto the seat.

"Airport." She ordered as she shut the cab's door. The driver nodded his head and took off. Clary turned around to see the Institute one last time, as she stared a golden blond boy caught her eye. But his back was turned to her, he was most likely getting ready to go back to Magnus'.

"Good-bye Jace." She whispered as a faint smile formed on her face. She then turned back around to stare at the traffic ahead of her. She had enough money to get where she was going, thanks to her mother and Luke. She knew she would be alright financially, well for a little while at least. Once she found a town she liked she would find a part–time job to make some extra money. Also she would have to text her mom to tell her that she wasn't living at the Institute anymore. Just to give her a heads up, she couldn't call. A call could be traced, so the only way she and her mom communicated was by texting, the good thing about that was that she didn't have to hear her mother yell at her and the bad thing about it was that she never heard her mother's voice anymore. All Clary had now, were memories. Nevertheless, now she would start a new life, a new beginning, no matter how much it killed her inside. She had to move on; it was the only thing to do.

I hope you guys. Please review and tell me what you guys think so far.
