Hermione Granger finds the Mirror of Erised at Hogwarts instead of Harry
Hermione Granger wandered down the corridors of Hogwarts. She was trying to clear her head so she could do her homework. She had been in the Gryffindor common room studying and she simple couldn't finish her potions essay because her thoughts were everywhere, so she decided to take a walk. She was walking without really watching where she was going when she found herself in front of a door she had never seen before. Curiously she opened it. Hermione walked into the room and saw a mirror. This mirror wasn't a normal mirror, it was so elegant and when Hermione looked in it she didn't just see herself. Hermione saw herself, except she was much older. As Hermione studied herself in the mirror she saw a beautiful young woman with her Hogwarts uniform on and her books in her arms. She was Head Girl and top in her class. She held herself with confidence and next to her were an older Harry and an older Ron both standing behind her, and having her back.
Hermione sat down in front of the mirror, just staring at it. After about a half an hour she realized she had homework to get back. She quickly finished her potions essay when she got back to the common room then went to get Ron and Harry. Hermione was going to show them the mirror that she found so fascinating. Because they were her friends after all, and friends shared thing with each other.
