The Mortal Instruments

[you will have to have read the mortal instruments trilogy to know what I'm talking about]

You may know that their is a book trilogy called the Mortal Instruments: City of Bones, City of Ashes and City of Glass. Well I once had this fantasy, story type, daydream:

Jace and Clary were walking (somewhere) and I came out and stopped them. I explained this (the truth) to them: I am their half sister and my mum is Jocelyn, but my dad isn't Valentine. They asked me who my father was and I said he was Luke. I then said they never knew of me because when I was younger (a year younger than Clary) a warlock stole me and did experiments on me. [clary was to young to remember me]. As Valentine did experiments on Jace and Clary, the warlock (which was Renwick) did experiments on me giving me warlock powers making me the ultimate weapon as I still had shadowhunter skills etc. We went on a kind of mission to save Jocelyn...

I couldn't finish this ultimated daydream as I was interupted to go to lunch.
