Jane was rather frustrated. She had written Will (her twin brother), who had said that he wanted to come see her for the summer holidays. But, her parents are being stubborn and not paying his way to get to London from California where he is staying at that very moment. She had tried to convince them to let her go to Cali and visit Will for the summer, and then fly back when School starts, but they couldn't be "away from their darling daughter" for so long. That made Jane mad.
Jane didn't understand why they didn't love Will as much as they loved Jane. Her grandmother, whom Will lives with, doesn't understand either. All Jane wants to do is see her brother. And by the looks of it, it's not going to happen. So that made Jane mad. More than mad. Jane was furious. She wanted to slap her parents in the face and run away. But she knew how much her parents loved her. And if she ran off, that would break their hearts...and she couldn't stand to see them hurt. But she also couldn't stand to see her brother hurt.
Jane was confused on what to do. She furiously went into the Slytherin Common room and threw her stuff on the floor and sat on the couch and grumbled. Jane wasn't sure what to do. She could disappoint her parents, and run away to see her brother for the summer, and come back to be miserable, or she could stay in London, and make her brother upset because she couldn't come down. Either way somebody got hurt, and she didn't like to see people she loved getting hurt. But unforuntantley that was how it was at that moment.
When she saw the younger student throw her book into the fire, she smiled. What could that little one possibly have to worry about? She seemed so simple and full of life. Her life probably wasn't as screwed up as Jane's, well, at least she hoped not. Jane looked at her and said, "Now, that's not a way to handle a book. It did nothing wrong." As Jane looked at the book, she pictured her parent's faces instead of the pages that were now turning into ash.
