Mortal instruments and Infernal Devices mash up

The war has been started will Jace, Alec, Magnus, Will, Jem, and the others survive or will Sebastian win the war?

CLARY

"Sebastian, no. I'm not helping you" I told him. He nodded like he understood but I knew otherwise; Valentine did the same thing. Sebastian fixed his dark eyes on me

"Clary, my dear sister. you don't have a choice" We were standing in luke's apartment, circling the couch. Sebastian did something to Jace, making him as still as a statue. I silently prayed to the angel that someone would walk in and save us. That's when Sebastian launched himself at me. He had me pinned, my arms under his knees. "Clary, I have been waiting so long for us to be together. Valentine's children, finishing what he started" he was smiling as he spoke. I closed my eyes and tried to wiggle my way from underneath him.

"You're crazy!" As I spoke, liquid dropped onto my lips and into my mouth. I looked up at him to see the mortal cup in his hands. Oh my angel, Please someone save me. I closed my mouth tight, no letting him pour anymore. He got a hard grip on my mouth, prying it open enough to slowly pour it in. He kept his hand on my chin, keeping my mouth shut so I couldn't spit out whatever he wanted me to drink. I looked to Jace willing him to move, yell stop, or something but he stood motionless. Tears sprang into my eyes as Sebastian's grip only got tighter my lip began t bleed fromt eh force of the cup causing me to gasp and the foul tasting contents of the cup to burn my throat. I closed my eyes willing just to end it all and let out one loud scream. I felt Sebastian's weight move off of me from his heavy breathing I guessed he had a hard time.

"Get up...now"

Obediently I got to my feet without calling him a dick or a bastard and knew instantly what he had done. He came to my side and I felt the cold steel against my palm, looking down I saw the sword and felt a sense of power. Sebastian moved Jace so he was kneeling in front of me and just grinned

"Kill him"

The only instruction I received and was so egar to obey. Raising the sword I positioned it to rest above the blood rune and looked into his eyes. I could have sworn I saw a bit of remorse or something in those golden eyes but it was quickly replaced by a glazed over look. By the angel! my brain screamed Don't kill him! You love him!

"Not anymore"

I responded out loud much to Sebastian's confusion and raised the sword. Hearing a door slam Sebastian looked out the window and promptly slammed his fist against the radiator. He glared at Jace who held his stele in his left hand a small smirk came into view before disappearing. Boots thundered up the steps followed by shouted instructions. It was now or never and I brought the sword down as Alec burst through the door. Yells errupted as blood painted the cover of his bare chest. Everything seemed to move as slow as it could, but inside my head was faster than ever. The two sides of my thoughts were screaming

"You killed him! You loved him! Sebastian should be proud. I did what he asked"

"Let's go" My brother growled in my ear as he pushed me away. The sword dropped from my hand, next to Jace who was face down on the ground. Sebastian pushed me to what was my room. I looked around and I suddenly felt like I was drowning. Emotions swimmed my head, drowning me in mixed thoughts and feelings. Hatred for Jace won it's way to the top. Hatred for Simon and Isabelle, For Alec and Magnus. Why did they think fighting against Sebastian is good thing? Sebastian pulled on my wrist, leading me out the window, and onto the fire escape.

ALEC

"Stop them! Around the building!" I screamed as I ran to Jace. I fel on my knees next to him. Rolling him onto his back I saw all the blood coming from the big gash on his chest.
