Clary stalked back to her and Isabelle's dorm with a scowl on her face. After class, Jace was swarmed by the other girls in her class. She turned her painting in and made a run for the door before Jace could make any smartass remarks. Clary felt a sharp pain in her chest at the thought of Jace surrounded by those other girls. She told herself that it was just a pain of hate and that there was no way she'd ever be jealous of anyone who was with Jace Lightwood. But maybe….she shook her head. Don't be silly, she thought. When she finally made it to her dorm, she walked in to find Jace sitting down on her bed. "Are you fucking kidding me?!" she shouted as she looked up at the ceiling. Jace smirked and lay back on the bed, "Nice to see you too Carrot top." Clary cringed when she heard the nickname he gave her back in high school whenever they were friends, and she liked him. Before Clary could snap back at him, Isabelle came back into the room. "Oh, hi Clary. I forgot to tell you that Jace was coming over to help me study for my history midterm," Isabelle said with a grin. "I'll just go to the library," Clary said as she looked at Jace lying on her bed, "And then I'll go buy new sheets." Jace scowled at her but didn't say anything. After getting her sketch pad and some pencils, she walked to the library.

"…So Benedict Arnold was a patriot who informed on America to the British army?" Isabelle asked and looked at Jace expectantly. Jace was staring at the green pillow next to him. Isabelle hit him on the arm. "HEY! Damn, you don't have to beat me up. Yes, Benjamin Franklin helped write the Declaration of Independence," Jace said as he rubbed his arm slowly. Isabelle glared at him and threw her book down on her bed. "Okay, first of all, I said Benedict Arnold. And second, what's on your mind? You've been staring at Clary's damn pillow since she left. Spill." Jace looked at Isabelle and shrugged, "I was just thinking about what I did to Clary senior year." Isabelle thought back to prom night of senior year:

Clary and Isabelle were sitting at their table when Alec and Jace walked up. Jace took the seat next to Clary and looked out at the dance floor. Jace's date, Aline, was dancing in the middle of a group of people. Jace looked her up and down before looking at Clary. "Your cousin is extremely hot," he said with another look towards Aline. Clary rolled her eyes, "Jace don't try anything with her. She gets hurt very easily, and I will personally kill you if you hurt her." Jace smiled down at her tiny frame sitting in the chair, "You can't even reach me." She smiled back up at him and shook her head. Their friendship had been like this for years. Both of them would flirt non-stop, but neither of them would express their feelings. Sebastian Verlac, Jace's best friend walked over to the table and stood in front of Clary, "May I have this dance?" he said with a grin as he held his hand out. Clary blushed and nodded while taking his hand and letting him lead her to the dance floor. "So Clary, I've been thinking that you and I should hang out more often," Sebastian said as they moved to the beat of the song. Clary nodded, "Yeah, I mean you seem really cool, and I'd like to spend more time with you." He nodded back and twirled her around.

Back at the table, Jace stared at the way Sebastian held Clary so close to him and scowled. He should be the one holding her like that and spinning her around on the dance floor. Just then, Aline came and sat next to Jace and put her hand on his thigh, "You seem a little distracted. Are you okay?" Jace nodded, "I'm fine. I'm just bored." Aline smiled and slid her hand higher up on Jace's thigh, "I can make you not bored if you'd like." Jace looked Aline up and down. Sure, she wasn't Clary, but she did have nice boobs and that red dress was riding up a little too high on her thigh. Jace felt his pants get a little tighter. He looked back to Clary and Sebastian dancing and shook his head. "Let's go," he said. They walked out of the gym and into one of the empty classrooms.

Clary and Sebastian finished dancing, and she walked back to her table. "He's a cutie. And I think he likes you," Isabelle said with a wink in Clary's direction. Clary shook her head, "Izzy, you know I like Jace." Isabelle rolled her eyes and went to dance with Simon. "Hey Alec, where did Jace go?" Clary said as she looked around for blonde curls. Alec looked around as well, "I saw him talking with Aline and then I saw them leaving the gym." Clary nodded and went to find him. She walked out of the gym and into the hallway. She started walking towards the bathrooms when she heard moaning coming from one of the classrooms. She shook her head and thought that some freshmen must be trying to score. She continued walking past the classroom. Out of the corner of her eye, she swore that she saw golden hair. It couldn't be, she thought. She slowly walked to the door of the classroom and looked in. She gasped and threw the door open. Jace was on top of a half-naked Aline who had her legs wrapped around Jace. "This room is taken," Jace said as he put Aline down and turned around to see who had opened the door. His eyes bulged out of his head when he saw Clary standing in the doorway with tears in her eyes. Clary didn't stick around for long before she bolted out of the front doors of the school. Jace couldn't register what was happening until Aline grabbed his arm, "Now that she's gone, we can continue." Jace brushed off her arm and ran to find Clary. He ran out of the doors and into the parking lot. Clary was standing behind Alec's truck crying. Before Jace could even get to her, Sebastian was pulling her into his arms and kissing the top of her head. Jace sunk back behind a car so that they could see him and looked at his hands. "What have I done?" he whispered to himself. He slowly stood up and looked back to where Clary was and his stomach dropped. Sebastian and Clary were kissing up against Alec's truck. Jace couldn't believe it. Sebastian KNEW that he liked Clary, and he was kissing her like she was dying and needed mouth to mouth. Jace punched the car behind him and stalked back into the gym. They'll pay for this. The door slammed behind him, and Jace felt like the door slammed on his friendship with Clary Fray.
