Lily Evans-Potter twin sister

Chapter Four:11 Years Later

I was wearing a beautiful emerald green dress that ended at my knees. I was in my apartment in the heart of London. I was actually making potions for Madame Pomfrey until I heard a light knock on my door. I waved my wand and disguised my potions. I slip my wand back into my hooker boot. I walk to the door and opened it to see the one and only Albus Dumbledore. I smile my hair was bright blonde today and had a braid on the side of my head. "Why hello Albus!" I chirp and gave him a light hug. "Hello Alexandrite my dear. Would you do the honor of being the potions master's apprentice?" I smile slightly. "Could I also be head of Slytherin with the head of Slytherin today?" I asked. He nods and I wave my wand and everything is packed and infront of us. I grabbed my trunks and apparate to Hogwarts with Albus. He lead me down to the dungeons and to a portrait of me, Lily, Severus, Bellatrix, Narcissa and Lucius. I smile. "Best Friends for centuries." Dumbledore says the portrait swung open. I grin it was elegant green black and silver. "Look at the time students must be wandering were I am. Come along dear it's just after sorting." Dumbledore says slightly smiling. I wave my wand and my dress turns into a tank top dress with the top silver and the skirt emerald that's short in the front and long in the back, a pair of ballerina flats and the black school robes. I had my hair natural again. I walk with Albus to the great hall. Once we entered everything was silent. I look at the staff table and saw a greasy hair and hooked nose man. Severus Snape. "Alright this is Alexandrite Evans she will be Professor Snape's apprentice and co head of Slytherin!" Dumbledore says. I walk slowly up to the table and sit in the empty seat beside Severus and some other teacher. "Alexandrite..." Severus whispers. " I stare at him blankly. I'm not as hyper as I used to be after Lily's death. "Come with me." Severus says grabbing my arm and pulling me out of the great hall. He took me to the dungeons and potions classroom. Once inside he locked the door and casted a silencing spell. I stare at him my eyes meeting his. "Where did you go?" Severus asked. I tilt my head. "When you left in our 3rd year." "France." "Why?" "Why what?" "Why did you leave?!" He screamed tears pooling in his obsidian eyes. "You called Lily a mudblood when we are not we are half bloods!! We were adopted Severus!" I scream. "Do you know your parents?" He asked. I nod looking down. "Only my father Severus. I'm shocked you didn't recognize me Severus. Cissy,Bell and Lucius did." "What do you mean?" "Me and Lily real names are Lily Madison Riddle and Alexandrite Pansy Riddle. And Albus is the one who killed Lily!" I say lowly. "How do you know?" "I was with my father Voldemort the day Lily and Potter died!" I say and Severus pulled me into a kiss. I wrapped my arms around his neck. Once we pulled away he smiles lightly. "Be mine?" He asked. I nodded. I then look at him. What house did Harry get put in?" "Lily's." I smile. "I'll be back!" I say and quickly walk to the great hall. I walk to the Gryfindor table. "Mr. Potter may I speak with you?" He stands up I then go to the Slytherin table. "Pansy, Draco, Vincent, Gregory,Blaise come with me and Mr. Potter." They all get up and follow me.
