Jace had been racking his brain for weeks since he found out that Valentine was his father and Clary was his sister. He needed to clear his mind.

Walking out of the Institute and went for a walk.

After a while he realized he was in a part of the city he didn't recognize. He heard soft footsteps fall behind him and when he turned he saw a girl about his age.

She had dark brown hair and dark blue eyes.

She backed away and pulled the sleeves of her jacket down and zipped up her jacket and ran.

"Hey get back here!" Jace yelled.

He chased after her and tackled her to the ground. She started to squirm under his grip until she stopped when she looked into his eyes.

"I'm not going to hurt you." he said.

She looked away and pulled up her sleeves as well as his.

"I'm a Shadowhunter just like you." he said.

She pushed him off of her and stood. She pulled off her jacket revealing a tank top.

She was covered in runes from her neck to under her tank top.

"I know what you are, but I'm an outcast therefore I have no reason to be speaking with you." she said before turning away.

"Outcast? How are you an outcast?" he asked.

She stopped and turned her head slightly.

"I'm an outcast because I fell in love with another Shadowhunter who wasn't part of our group. And that Shadowhunter was you." she said.

Jace thought for a moment and it hit him.

"Nova wait!" he called running after her.

She turned and looked at him.

"What Jace?" she asked.

"Come with me. I'm taking you back home." he said stroking her face.

"Jace I can't an outcast has no priority to join another Shadowhunter group just because of love and old scars. I can never return, if I do I'll break Shadow rules. Goodbye Jace." she said moving his hand away and walking away.

Jace looked away. He decided to walk home, he knew he couldn't convince her.

Nova turned to corner and the rain started. She watched Jace walk away she hadn't cried in years and she felt a tear stream down her face.

"Jace wait!" she called.

Jace turned and looked at her. She walked up to him and threw herself into his arms.

"Take me home with you please." she said.

Jace wrapped his arms around the scared girl.

They walked home together and when they arrived at the Institute Isabelle and Alec were standing in the door way.

"Who is she Jace?" Isabelle asked.

Nova backed up slightly and looked down.

"Her name is Nova now move Isabelle I have to tend to her runes." he said.

"Jace where have you been!?" a worried voice exclaimed.

"Clary I was just out and about." he said.

The girl named Clary wrapped her arms around his neck and looked to Nova.

"Who are you?" she asked.

"Nova James Shadowhunter." Nova said.

Clary shrugged and turned back to Jace and smiled.

Jace smiled slightly in return and took Nova by the hand and led her inside.

"Looks like she's going to create a problem." Alec commented.

Jace took Nova up to his room and brought her inside.

"What is her problem?" she asked when he shut the door.

"It's Clary we're brother and sister, but we didn't know until our father said we were. We fell in love and kissed and well yeah you can see what happened from there.

Nova nodded and sat on Jace's bed.

"It's my fault for you becoming an Outcast. I should never have kissed you." Jace said.

"It's no ones fault Jace we were in love. A love that neither of us could explain." she said.

Jace smiled and sat next to her, leaning close to her he kissed her.

Nova smiled and stood up.

"So you're going to tend to my runes?" she asked.

Jace thought for a moment and nodded.

Hope you like I just watched the movie on Friday so I got the idea from this. Not to mention that I'm still reading the book. Review?
