I Don't own the mortal Instruments Characters but I do own this plot.

Clary:

I went down to the dining hall for dinner. Maryse sat at the front of the table, Alec and Izzy sat on each side of her, Simon was next to Izzy, Jace sat next to Alec with Alex on his other side, and Vic sat two seats down from Simon. She had saved seats for Carter and me. Where was Carter? I thought. Vic looked at me as if she was asking the same question in her head. I walked over and sat in the seat next to her. She leaned over and whispered in my ear.

"Where's Carter?" She asked.

"I don't know." I said.

"I thought he was with you." She said.

"We had a fight earlier this morning. He stormed out the training room. I haven't seen him since." I whispered to her.

Just then, Carter walks through the door. He hangs his head as he comes and sits in the seat next to me. He doesn't say anything or give me a glance. I sit there quietly. What was wrong with him? I asked myself. We had fights before but he has never ignored me before. We didn't talk to each other all during dinner. I went up to my room alone to go to bed. There was a soft knock on my door after I changed into my pajamas, which was just a pair of shorts and a tank top. I opened the door to see Carter standing there. I started to shut the door. I didn't want to talk to him not after what he's been treating me like today. Carter's hand stopped the door from closing on him. I glared at him. He sucked in a breath.

"Can I talk to you?" He asked. I opened the door wider to let him into the room. He stepped into my room and I shut the door behind him before turning to him.

"What you want?" I asked.

"I wanted to say I'm sorry for calling you stupid." He said. "You're not stupid you're one of the smartest people I know."

I gave him a little smile. "It's okay." I said. "I know you where mad that's all. You didn't mean any of the things you said."

"I meant everything I said this morning." He said. "Except for saying you are stupid."

That really didn't make me feel better. He was jealous of Jace because Alex wanted daddy daughter time with him. Carter has been a father to her and he always will be to her.

"That's not what I came to talk to you about." Carter said pulling me out of my thoughts.

"What is it?" I asked. I could see he was nerves. He messed with a bracelet around his wrist that Alex had made him when she was six. He always messed with it when he got nerves.

"I wanted to talk to you about the situation with Sebastian." Carter said. I didn't want to think about him after what he almost did to me this morning after Carter and I had our fight. What would Carter want to talk about him for? I haven't told him about what happened with Sebastian.

"What about him?" I asked.

"How would you feel if you got to spend a day with him and I could promise you, you wouldn't be hurt?" Carter said. I froze at that. Why would he think I would want to spend time with Sebastian?

"I wouldn't go still." I said. "I wouldn't want to go in the first place."

He looked worried. "I would be good to spend time with your brother."

"He isn't my brother!" I yelled. "He's a demon, Carter! Do you not understand that? You've never really talked to him. You don't know what he's like."

"It was just a suggestion." He said quietly. "You can sleep on it and give me your final answer in the morning."

"No I don't want to think about it again cause the answer will always be no." I yelled. "What's wrong with you today?" He stayed quiet. I walked over to the door and opened it indicating that he should leave. He walked out my room and I slammed the door behind him. I put a lock rune on the door so he couldn't get in while I was sleeping. I walked over to my bed. I climbed under the covers and let sleep engulf me.

Carter:

I felt so guilty about what I was doing but it had to be done right? I went back to my room after Clary had gotten upset about going with Sebastian. I aid on my bed and thought about everything that happened. She really hated him. How was I going to get her to agree to spend one day with him? Maybe if Jace had told her to do it then she wouldn't be too quick to say no.

"She said no that quick?" A voice said from the window. I turned to see Sebastian sitting on the window seal.

"How did you get in here?" I asked. Sebastian looked at me and chuckled.

"You're not that bright are you?" He said then chuckled again. "I don't know what my sister see's in you."

"She's mad at me right now." I said.

"Oh she didn't like the idea of spending a day with me?" He asked with a wicked grin on his face.

"You knew she would refuse?" I asked glaring at him.

"I knew she wouldn't want to at first." He said. "That is why I came. I won't wait forever. I'll give you three days and two nights to convince her to spend one day with me."

"What happens if she doesn't agree?" I ask.

"You wouldn't fulfill your part of the deal so I would not do my part." He said. "I would not touch Jace for your own need for him to be gone."

"I can understand that." I said.

"But… If you don't fulfill your part. I will take my only family that I have left with me and you will never see them again." He said with a wicked smile on his face before disappearing.
