Clace - TMI AU

11

Clary opened her room door and saw Izzy lay on the floor, unconscious. Any excitement had fled her body and was replaced by fear. She checked her pulse and felt it beating under her fingers. Relief washed over her instantly. Just then the door slammed shut and she felt something hit her chest, sending her flying across the room. She looked up in surprise and saw two people walking towards her.
"Sebastian, what are you doing?" She croaked.
"Don't worry darling, i'll explain. All in due time." He turned to the man next to him, "Bind her hands and feet."
The man clicked his fingers and Clary's hands and feet were tied.
"Don't shout or Isabelle dies."
"I'll do whatever you want, just leave Isabelle out of this."
"I will, once we are out of the institute." He turned to the warlock he had come with. "Remove anything from her pockets." The warlock went over to Clary and emptied her pockets. He took her stele and phone and threw them aside.
"Now portal us back to my place."
Her head was throbbing and she felt like she might pass out. She closed her eyes and when she opened them she was in an apartment, presumably Sebastian's.
"Clary, Clary, Clary. I'm shocked you didn't figure out who I was."
"What are you talking about?"
"Don't you feel a special connection between us? Like a familiar, Sorry familial connection?"
Clary looked at him blankly. He sighed.
"My name, is Jonathan Christopher Morgenstern, do you know what that means?"
Clary's eyes widened with shock and understanding but she didn't say anything.
"I am your brother."
"No, that can't be true, that's not possible," she whispered.
"Ah but it is true."
"But it can't be, Jonathan died, that's why my mom left Alicante. Valentine fed my mom demon blood whilst she was pregnant with him and he couldn't handle it when he was born. He died a few months after birth."
"Well clearly not. I'm right here."
"You can't be Jonathan."
"I have green eyes, just like you."
"But there was a baby and she buried him."
"Emphasis on a baby and not me. Valentine tricked her. He stole someone else's baby and sent me to Edom be raised by my real mother, Lilith. How do you think I burnt your arm with only my hand?"
She looked down at the faint scar that was left on her wrist.
"You kissed me! Why did you kiss me?!"
She felt sick to her stomach and made sure Sebastian could tell.
"Why is that an issue?" He demanded. "Egyptian siblings had romantic relationships. In fact I believe King Tutunkhamen's parents were siblings and married one another."
"You're disgusting. You're revolting."
"Well I knew why I needed you, I just thought I'd have my fun with you first." He said mocking her. She made a gagging noise and he went red with anger.
"What do you need me for?" She asked quietly,
"What?" He barked. She repeated what she had said a little louder and slower.
"I said, what do you need me for?"
"I need you so I can ressurect Valentine."
Her jaw dropped.
"You want to ressurect that monster? Why? He's been dead for almost 20 years, how are you going to do it?"
"Easy, one of his loyal followers found a way to preserve his life but he is practically dead, just not completely. They also froze his body. To revive him his own flesh and blood needs to be used. So, you."
"Why can't you be used?" She asked worriedly.
"Two reasons; one because my blood isn't pure, it has demon blood but yours, oh yours is perfect. It has extra angel blood so it's more concentrated and powerful in the sense that is could bring him back to life and he would be strong, not need too much time to recover." He paused.
"What's the second reason?" She asked through gritted teeth.
"The second reason is, whoever does it dies." He said bluntly.
She stared at him.
"Just kidding, gosh you're so gullible, lighten up! Whoever does it is bound to Valentine. Whatever happens to you happens to him and vice versa, etcetera etcetera. " Her head throbbed as she processed what he said.
"You're not going to get away with this you know. Jace is going to come looking for me an-"
"Ah Jace, you were in love with him every though you were dating me, I could tell by the way you looked at him. Pretty rude if you ask me."
"He's gonna come for me and stop you before you can ressurect him. Just you watch. He'd never let me down. Unlike you, who clearly isn't a very reliable person."
Sebastian started at her. He clicked his finger and gestures to the warlock who snapped his own fingers knocking Clary out.

She woke up several hours later. Her head ached and there was a dull throbbing in her left ear. Her hands were bound in the air to what seemed like invisible chains. She was standing up, barely. She couldn't move or speak. Her energy was draining out of her like water running from a tap. She tugged her arms but couldn't break free. Sebastian came into the room and shook his head at her.
"Those aren't going to come loose. You may aswell give up. Francic, knock her out again and make sure she doesn't wake for a long time."
She began to panic as her vision blurred and before she knew it she fell into a deep slumber.
