Harry has a sister
What if Harry hadn't been an only child. What if he had a twin sister and together they were supposed to fight voldemort, but they got separated. She's a metamorphagus named Jessica. Raised in Hogwarts knowing so much about the wizzarding world except for who she was and what she had to do. This will come from Jessica and Harry's pov maybe others. This will start in the first year.
PROLOUG
Jessica's pov Tomorrow's my first day of school in a place I've grown up. I already know a lot of magic. I'm a witch. Professor Dumbledor (who's like a farther to me) is telling me to calm down and get ready so I can get on the train right away once Dumbledor apparates us there after doing something. I don't know why. Probably so I can mingle. Oh well it doesn't matter. I sit down fiddle with my wand holly and pheonix feather Olivander had looked surprised and dragged Dumbledor somewhere. After I had got a cute fluffy black and white kitten. I got lost. I started playing with my appearance looking into a puddle my long black hair and bright green eyes turning amber. I looked up and was so shocked my appearance became normal right away. I saw Hagrid and a boy, it's the boy that has caught my attention for two reasons, one was that his hair was the exact same shade as hershis pale skin was the same shade and the eyes. They could have been twins. They had to be related. The second was the scar on his forehead it was the same as the one on my hand. It was Harry Potter the legend but where's his twin I thought idly. Then it hit me hard I'm his twin Hagrid noticed me staring as if I had saw a ghost. My stomach clenched I cant breath I thought I tried but it hurt as if the air was a brick. There's dots I thought detached. I felt Hagrid's arms scoop me up hear him telling Harry to hurry up. Maybe it's serious. suddenly I started trying to get out of Hagrid's arms to tell Harry the truth. Slowly I drift into darkness. (the dream is in italic)I was in somebody's arms. No my mums, she says I'm grown up for a one year old. I can see Harry playing on his kiddy broom. Dad's laughing and helping we're outside. It's Halloween. I can see someone walking towards us that isn't dressed up. I point mum calls to dad. He says he'll hold him of. Mum put's us in our cot and swings around. He's there. Mum tells him to take her instead. He holds up his wand says something. A bright green light shoots out mum falls to the ground. He's about to hurt Harry when I scream for him to stop and not hurt him. He laughed. I fling myself at him and bite down. He flings me at the wall points his wand at me and Harry all I think about is mum and dad. Harry's confused he thinks it's dad. I dragged Harry behind me and put my hand in front of my face. The light comes I let myself sink into the darkness.
