Clary walked into the institute holding lunch from Taki's as a surprise for Jace. She walked into the kitchen, only to find Church. "Hey Church, where's Jace?" He stood up and walked down the hall towards Jace's room. She thanked the cat and opened the door quietly in case he was asleep. What she found truly horrified her. Jace was shirtless in bed with some blond bimbo, who was also shirtless. Clary dropped the bag of food and let out a small gasp, turned and ran away.

Clary ran down the hallway and could hear Jace calling her name and running after her. She ran into her room and drew a locking rune on the door. Jace started banging on her door and yelling for Clary to let him.

"Go away Jace, I mean it" Clary yelled, hoping he would listen, but he just continued to bang on the door. Knowing she had to get away before he could get in, Clary drew a portal rune and stepped though. She landed in an alleyway near Java Jones. She slid down the wall, curled up in a ball and started to cry. It had finally hit her. How could he. How could he have cheated on her? He said he loved her. Obviously that was a lie. He said it himself, to love is to destroy, and to be loved is to be the one destroyed. Why would he love Clary? She continued to cry, and sometime while she had been sitting in that alleyway, Clary decided that she to, would not love.

Meanwhile, back at the institute, Jace continued to bang on Clary's door, begging her to let him in. If she would let him in, he could explain what was going on, that he had no choice in doing it, that Clary would be hurt, possibly killed if her did not, but he was not going to yell this though the door. He finally came to his senses and drew an unlocking rune on the door, and burst into the room, only to find it empty. He ran out of Clary's room to the library, where everyone was and whispered "Clary's gone".

"What" said Izzy, "we can't hear you Jace"

"Clary's gone" Jace yelled "and it's all my fault"

"Wait, Jace how's it your fault, what did you do?" asked Alec

"It's a long story that I'll explain later, but for now we need to find Clary. I don't know where she went, she was in her room and then I finally got in she was gone. She must have used a portal rune. It could be the only explanation, she could be anywhere."

"Okay, Jace calm down, you and Alec go get weapons, I'll go check Clary's room for any clues" Izzy ran from the Library to her room to grab whip. She then ran to Clary's room, only to find it locked once again. Confused Izzy grabbed her stele and drew an unlocking rune. She open the door quietly, to find Clary in her bed, facing away from the door. Her small frame was shaking with sobs, and the occasional gasp could be herd. She quietly closed the door, drew a locking rune and walked towards the Armory to find Jace pacing and Alec applying runes to himself.

"Well" Jace asked Izzy "Could you find anything"

"Clary's fine, she's in her room as we speak" Jace let out a sigh of relief and stated walking out of the weapon room. "That doesn't mean you should talk to her Jace. She's hurting a lot right now. Talking to her would only cause her more pain." Jace stopped walking turned and gave a slight nod. Then turned again and walked down to the hall. Izzy turned to Alec. "What do you think he did?"

"I don't know" Alec answered "but it must have been pretty bad, Clary's one tough girl, to break her like that… I don't know"

"Well, night Alec"

"Night Iz" Izzy started walking back to her room, with nothing on her mind, but what Jace could have possibly done to make Clary this sad.

The next morning, Izzy went to check on Clary, but as she approached her room, she saw that the door war partially open. Praying to the angle Raziel that Jace hadn't gone to Clary, she looked into the room, to find it thankfully, empty. She then went to the kitchen, hoping to find Clary there, but only found Church. She grabbed an apple, then went to Church and asked him where the short red head was, and after receiving a scratch between the ears, the cat stood and started walking. Isabelle found herself being lead to the training room. She looked in to see just the girl she was looking for. She was in the room with Alec who was trying, almost successfully, to teach her how to flip. The thing the scared Isabelle about this was whenever any of them had tried to teach Clary to flip before, she would scream her whole way down, fail miserably, then laugh when she finally hit the bottom. Now she was completely silent. Her eyes where red and puffy, as if she had been crying for a long time, and there was not a hint of happiness in them.

"Clary, maybe you should take a break" she heard Alec say "you've been doing this for nearly two hours."

"I've nearly got it" Clary replied, "but you can go eat breakfast if you want, I'll be done soon."

"Ok Clary, but be careful" Alec answered "and make sure you come get some food to." Clary just looked at Alec and then started to climb the ladder.

Alec turned to the door and saw Izzy and tried to smile but it didn't quite reach his eyes. They walked down the hall to the kitchen together and Alec said "I'm concerned about her Iz, I found her in there 5am and it seemed like she had been there for a while before that, she didn't eat last night, and she hasn't eaten this morning, and she didn't take one break."

"And when I found her in her room last night, and she was crying, but the redness in her eyes would have disappeared by now if she had of stopped soon after that, her eyes wouldn't still be that red" said Izzy.

When they went into the kitchen Jace was sitting at the table, eating a piece of toast. He looked like he hadn't slept at all the night before. He looked up when he heard Alec and Isabelle walk into the room. He had heard what Isabelle had said, and felt horrible. The last thing he wanted to do was make Clary sad. He had been up all night thinking of ways to explain to Clary what had happened, to apologise. "Hey guys, I was wondering if I could practise something on you"

"Sure Jace" Izzy said

"Okay" Jace took a deep breath "Clary, I'm so sorry. I never wanted to hurt you. I love you. I had to do what I did. I didn't have a choice. If I didn't, Victoria, a warlock, said she would hurt you, kill you even. I couldn't bare that. She said I had to, because apparently it makes warlocks stronger, being with a shadowhunter and I have extra angle blood, so she thought it would be more affective. I tried to tell her it wouldn't work but she wouldn't listen. You were never meant to see. I'm so sorry. Do you ever think you will be able to forgive me. Please Clary. I need you to forgive me. I can't be happy without you. You are my world, my everything." Jace looked down at the table "what do you guys think?"

Izzy a tear in her eye and smiled, "if that doesn't work, I don't know what will."

Alec looked shocked "A warlock black mailed you? Victoria you said her name was? Maybe Magnus knows her. It's illegal to blackmail a shadowhunter."

"I know that" Jace said "but I couldn't risk it. I'm going to go talk to Clary. See you guys" Jace walked out of the kitchen and walked towards the training room, only to find it empty.
