".Don't make me say. Adava Kedrava." And a stream of green light came from the tip of Alexia's wand and hit a mouse when just seconds before she had it pointed at Hermione's neck. Suddenly her eyes were empty and her face was blank of any emotion and she slowly turned to Harry and muttered something they could not understand Ron pulled Hermione away from Alexia and tried to pull Harry when Snape of all people came walking down the corridor "well, well, well, what have we here"His cold voice said. "Eve, lower your wand, although you are in my."Alexia had whipped around and shouted "Adava Kedrava" and sent Snape flying into the wall. He was dead. Killed in front of three 5th year students by a fourth year and unable to do anything about it. Alexia was now turned back to Harry and muttering the same thing as before and she slowly raised her hand to Harry's scar. As she did so he felt that piercing burn on his forehead. As she got closer it became worse, it became so bad he could not move. She finally touched her hand to his forehead and pressed it hard upon the scar. Suddenly her eyes were full of feeling and a look of pain came upon her face and she fell to the floor. She was lying there like a dead body but breathing and there on her hand was a lightning shaped scar.
