I kept running to the dungeons, looking for a bed where I could vent my years of suffering. Death, that's what Izzie wanted for me, death. But what I wanted for her was pain and sorrow. For her to have as much misery as possible. I wanted to gouge her eyes out of their sockets, hang them around my neck, and then cook her meat and serve it to the Slytherin table. Undoubtedly that would be very poetic, it would be poetic evil. Going down to my common room I found some snakes that had not come to eat; They were sitting there talking about I don't know who when they saw me arrive. Like a group of birds, they acted at once: their cold, murderous gaze followed me. I was already home with my dear snakes! I passed them and went up to my room, well the shared room. I looked to see if there was anyone ... No one. I couldn't control myself anymore, I slammed the door and ran to my bed to cry.
I woke up slowly. I had fallen asleep without realizing it, I really needed to sleep after so much accumulated tension. But of course I had skipped potions. Oh no, Professor Snape is going to kick me out of the castle. Damn. For the past few years, Professor Snape had been continually punishing my sister and me. More than anything, because of our fights, we were good students; Isobel was good at defense against the dark arts and I was better at potions. We always had fights over anything, even if it was a look. Snape was tired of us.
―I want her to die. I want Izzie to die.
My heart was still heavy. It seemed like I was scared to death. Rather than my sister blurting that out, in front of everyone, it had been the icing on the cake. There was no longer any hope that little Izzie still lived inside her, sweet and tender. That really hurt. Isobel was a stranger; she was a 16 year old girl, cold and calculating. She moved among the worst Slytherins and rumors said that she had hooked up with almost all the boys in our class. She was a manipulative witch. She always got what she wanted, and if someone got in the way ... Well, it was best not to, she didn't care about the damage caused, nor the corpses that she left on the way. She was a witch of care. Instead, she had been very different before coming here.
My little sister Izzie, she was the most charming girl in the whole town. She had many more friends than me. They all wanted to be with her. I loved Izzie very much, she was my beloved sister. She always had a smile for me, for all my ills. How could she have become that cruel being of now? But it had happened. I supposed that inside her, she was hiding that treacherous snake. Waiting to go out to bite every living thing. At first I insisted on making her see reason, but I only received stabs and every day it got worse. I gave up trying to bring her to the good side, because I had forgotten that she was a Slytherin in all her condition. It was useless. I had lost my sister forever.
―I have to go, it's time for punishment.
I left the bedroom heavily. Thanks to Merlin they were all in her class. I was at the door of the potions classroom earlier than expected. I knocked twice before venturing inside. Nobody answered. I opened the door slowly, though that didn't stop it from squeaking open. There was the completely empty potions classroom, well, there was Snape behind his table. Examining some jobs.
―Miss Rosenberg. What a detail that you saved me from the trouble of looking for you.
―See Professor Snape ...
―Be quiet! I don't want to hear your repeated excuse, I am ashamed of you. You know what the punishment is for missing my class.
Upon entering the room I could see some cauldrons spilled on the floor, surely they were the boys from first year. Damn kids. I already knew very well what my punishment was.
―Hurry. I have another class in five minutes.
