I don't own the mortal instruments characters but I do own this plot.

Clary:

I woke up at five in the morning. I always woke up earlier than anyone else did because I liked the training room all to myself. I get dressed in shorts and a tank top. I almost walk out the door when I see a note that wasn't there last night on my nightstand. I pick up the note and read it.

Dear Clarissa,

I will pick you up around six this morning. Don't tell anyone where you're going or there will be consequences.

Your brother,
Jonathan

I look at the clock it read 5:15. I put the note back down on the nightstand and go to the training room.

When I get down training it's 5:47. I take a quick shower and get dressed. I walk down the corridor to Alex's room. She's still asleep. Her red curls are in a tangled heap like my hair is when I sleep. I sit on the bed next to her. She slowly opens her sleepy eyes. I brush some hair out of her face.

"Mommy" Alex asks in a sleepy voice. "Is it time to get up?"

"No sweetheart." I said in a soothing voice. "Mommy's leaving for the day and wanted to see you before I go."

"Where are you going?" Alex asked.

I lean over and kiss her forehead. "Just promise you'll stay here at the Institute with your daddy." I said.

She nods "I promise."

"Okay. Go to sleep." I said. "Daddy will wake you up when it's time for training."

She closes her eyes and instantly falls back to sleep. I know she won't remember any of this when she wakes up. I kiss her forehead before I leave the room.

I stop at Carter's room before going back to my room to wait for Jonathan. Carter's already awake and sitting on the bed. He looks up at me.

"When are you leaving?" He asked standing up.

"Now" I said. "Make sure Alex doesn't get into any trouble while I'm gone."

"I will." He said.

"I'll be back later today." I said. "No one needs to know where I am. So if someone asks just say I had a few errands to do and I won't be back until later."

Carter nods. I turn on my heels and walk back to my room. When I get there, I'm not alone. Sebastian is sitting on the window seal. He looks over at me and smiles.

"Ready to go Clarissa" He asks. I avoid looking into his black demon eyes and nod. Sebastian goes over to the wall and draws a portal.

Sebastian grabs may hand and enter twine our fingers together. His skin was cold. It felt so wrong as if I was holding ice in my hand. I didn't want to be touching him. I wanted to rip my hand from his grasp and run away with Alex where he could never find us but he would find us and I promised I would behave for the day with him. I give a small smile and he returns it with his own. We turn to the portal and he pulls me through with him.

We landed hand in hand in the middle of a living room. It had a flat screen TV hanging on the wall in front of us. There was a black leather couch against the wall behind us facing the TV. There was a glass coffee table a little in front of the couch. There was a glass stair case behind the love seat to our right. There was a door just at the bottom of the stares.

"Where's that lead to?" I asked nodding towards the door. Sebastian turned to see what it was I nodded at.

"That going into the kitchen" He said turning back to me. "Are you hungry?"

Now that I think about it I haven't eaten all morning. I was hungry but I didn't want to eat anything Sebastian made me. I didn't want to go hungry all day though.

"I didn't eat breakfast." I said. He smiled.

"Well let me make you something to eat." He said. He turned and headed to the door.

"No eggs." I called as I followed him through the door. "I don't like eggs."

He chuckled. "I remember you saying that." He said. "Besides I don't even know how to make eggs." He chuckled again as if I should have remembered.

After he had made me waffles with bacon, he showed me around his apartment. I had to admit it was very nice. There was a hallway at the top of the stairs. Jonathan led me down the hall and pointed out each of the rooms.

"That's the office," he said pointing to the first door on the right.

"This is my room," he said pointing to the next room.

The door was open and I could see inside. The walls where black and the covers on his bed where the same night shade black. The floor was a mess. There were dirty cloths scattered everywhere on the ground of his room. I looked at him but he was moving on to the next room.

"This is your room," he pointed to the door across from his. He opened the door so I could have a look at the room.

The walls were black like Jonathan's room but the bed had a dark purple shade on the covers. There was something lying on the bed that didn't seem part of it. I stepped in the room and walked closer to the bed.

It was a black dress. It looked to be skintight. It looked like it would only reach about mid thigh. There was a pair of heels lying on the ground next to the bed. I turned to look at Jonathan. He was watching me closely.

"The bathroom is down the hall if you would like to change in there or in here," he said. "It doesn't really matter. We leave in two hours. Make yourself... Presentable" he closed the door behind him on his way out after that.

I got dressed in the black dress. I was right about it being skintight but it didn't hit mid thigh at all. I didn't feel comfortable wearing it with Sebastian around. I walked down the hall towards the bathroom when the bathroom door swung open.

Sebastian stepped into the hall with a towel around his waist. He was all wet and there was steam coming of his skin. He must have been in the shower.

He sees me standing in the middle of the hallway looking at him. I couldn't help it his chest was in full view. His muscles where dripping with water. He came closer to me. He got close enough I could feel the heat from his body.

He leaned down but I turned away. What am I doing? I asked myself. I side stepped so he could go past me into his room but he had another idea.

He pushed me against the wall with his body. It was just like in my room but I'm not the one wearing the towel this time. He leaned down again and this time I couldn't turn away. He had one hand on my wrists above my head. The other hand was holding my waist.

He smashed his lips to mine. His lips moved against mine but I just stood there trying to get my hands out of his grasp. His hand tightened on my waist so much that it started to hurt. I gasped from the pain and Sebastian took to opportunity to stick his tongue in my mouth. I was still trying to get my hands out from his grasp.

"Stop fighting it." He said against my lips. How could I not fight it? He's a demon and my brother I shouldn't be doing this. I shouldn't even be here.

His lips were still moving on mine but I hadn't realized that his hand on my waist was slowly moving down the rim of my dress. I need to get out of here before anything else happens. I needed him to let his guard down long enough so I can get my hands out of his grasp. I began to kiss him back.

"See you like it." He said against my lips before I smashed our lips back together. I could feel him letting his guard down. Just a little more and I will be able to slip away. I deepened the kiss.

He let go of my wrist and picked me up. I wrapped my legs around his waist as he carried me to my room. He laid me on the bed and got on top of me. He ran his hands up and down my body. He pressed me down on the bed with his body. I felt disgusted about doing this but it had to be done because he had let his guard down.

I brought my knee up and hit him where the sun doesn't shine. He groined and I hit him in the face before throwing him off me. He was groining on the ground when I ran out the door. I shut the door behind me. Before I ran, I locked it from the outside.

I ran into Sebastian's messy room. I looked in all his dresser drawers for a stele. I finally found one in his nightstand. I could hear him yelling and banging on the door as I ran down the stairs to the living room.

I started to draw a rune on the wall when I heard a crash and one last bang. I knew he had broken down the door. I turned back towards the wall and continued drawing the rune.

I was almost finished when something struck me in the back making me smash up against the wall. I stumbled back a little away from the wall.

I turned to see Sebastian standing with black pants and a weapons belt on. He started walking closer to me. I turned back to the wall quickly when I realized I dropped the stele. Sebastian came closer as I looked frantically for it on the ground. I finally spotted it on the floor near the kitchen door. Sebastian followed my gaze and saw it lying on the ground.

I lunged for it and Sebastian ran for it. I grabbed it from the ground and side stepped before Sebastian could run into me.

I ran back to the wall but he grabbed my waist and pulled me back. Sebastian threw me to the ground. I whimpered in pain as I stood up and looked for the stele I had lost again.

I heard Sebastian chuckle as I was looking on the floor around me. I looked up at him and saw he was holding the stele in his hand. He put it in his weapons belt he wore. I glared at him and stood up from the ground.

"Are you going to fight me for the stele, little sister?" He said chuckling.

"I will kill you for it." I said sternly "and I am no sister of yours."

I lunged at him. I threw a punch at him, which he blocked easily. He tried to throw another punch but he caught my fist and hit me in the stomach. I flew back and hit the wall. I ignored the pain and stood up.

I lunged again I got a few punches in this time and kicked him hard in the stomach. He smashed into the glass coffee table making it shatter into a million pieces.

He was still on the ground when I walked up to get the stele out of his belt. He seemed to be knocked out. His head was bleeding and so where small cuts from his arms. I reached down to grab the stele from his belt when he was no longer there.

I didn't see him move but I felt the pain shoot up my leg. There was a big piece of glass sticking out of my thigh. I screamed from the pain. I fell to my knees and pulled out the glass. Blood started gushing out of the cut that was on my thigh.

I stood up and looked around. I could barely walk but I was determined to get out of here. Sebastian was standing behind me watching me. I glared at him and if looks could kill, he would be withering in pain on the ground. This would make getting the stele a lot easier.

"Sister you don't look good." He said walking in a circle around me. He kept his eye on me though. "Why don't you just give up? I'll heal you."

"I don't want you." I said before running as best as I could towards him and throwing a punch. He blocked it and grabbed my throat. He pushed me up against the wall.

"You should have listened to your friend and been on your best behavior." He said. He was cutting of my air supply and I could feel myself slowly chocking to death. "He made me a deal; you on your best behavior for a day just so I would kill angel boy."

What was he talking about? Who made the deal? Who wants to kill Jace? Realization dawned on me. Carter convinced me to come here for a day because he made a deal with Sebastian.

Sebastian was still holding me against the wall by my throat. How could Carter betray me? How could he give me to a demon because he was jealous? How could he lie to get me to come here? Sebastian cut me out of my thoughts.

"Oh." He said faking pity. "You didn't know. Well you won't have to deal with it no more. You should have listened to us." He squeezed tighter. I started to lose consciousnesses. My hands where trying to pull his hand away from my throat but he wouldn't budge.

I gave up trying to pull him off and hit him hard in the throat. He let go and stumbled back. I took a deep breath before hitting Sebastian several times in the head. He falls on the ground.

I grabbed the stele from his belt and limped over to the wall where the unfinished rune was. I finished it and looked back. Sebastian was still groining on the ground. My vision started to go black and I knew it was blood lose. I turned back to the portal and thought of the New York Institute before falling into blackness.
