my life as Jane the killer's sister

As another light dulled in one of my victims eyes, I pulled out my stainless steel knife slowly down making the cut widen and made the blood gush faster from both the wound and mouth. "would you hurry up the cops are coming!" My sister Jane sneered as she wrote her infamous "don't go to sleep you won't wake up" trade mark on the white plaster wall. Yes I know what you're thinking and yes Jane the killer is my sister, even though in her story it said that everyone in the family except Jane was killed. The reason why I'm still alive is because 4 years ago when me and Jane were about 16, I was experiencing weird feelings until I found out they were powers, where I could start anything on fire if I was mad and the list of strange powers goes on and on. One day after school I was being bullied by the same group of girls that had picked on me and Jane for the last 11 years they were the populars as the school had named them , they painfully shoved me into a locker and slammed the door behind. To make a long story short when they did that to me I exploded with anger and lets just say the girls and the school are no longer on this planet. When the news broke that the school was burned down and the girls were no where to be found,  my parents questioned me since I came home three hours later with my charred school outfit and ragged hair with bits of debris tangled into it, I tried to tell them that it was self defense but nothing worked. The next day they forced me into an insane asylum after I finally told them what really happened. I didn't know that it was the last moment I would spend with them or see there faces before they were slaughter by the grease head that Jane has been going crazy trying to find , though I don't even  know his name but I would have told them I loved them and would have never told them to go to hell. After four years of torture and straight jacket hell the people that held me in this place had let me out after all my parents put me in there till they released me and now that they were no longer living they saw no point in keeping me in the place,  when I left out of the heavy metal asylum doors  I met up with Jane in the waiting room and the rest is history. I took the knife out of the man and tagged up with Jane who was already at the back window that was broken since that was the way we got in from, we both carefully got ourselves out of the broken, jagged window as we heard the blazing police sirens come closer to the scene. I followed Jane who was running full speed but was staying low till she stopped abruptly. I stopped short kicking up dirt Jane turned around and looked me in the eyes and I looked into her black soulless eyes. Then  said " I think it's time you met a few friends of mine."
