She spent every waking minute reading up on animagus and soulbonds, her school work could not suffer - that was not an option for her. So she created a schedule to divide her time equally. Unfortunately that meant her friends were at the bottom of the list, she even managed to talk to Theo more than Harry and Ron as she spent so much time down in their dungeon. Harry had taken to walking around the castle with his nose stuck in the map, he kept prattling on about Malfoy disappearing every time he tried to follow him anywhere. She knew that Malfoy had been spending a lot of his time in the dungeon, which mustn’t be showing up on the map - presumably un-plottable. But she couldn’t exactly say that to her friends who thought she was always studying somewhere in the castle. She had even told Harry that she uses the room of requirement now and then for the complete silence, a horrible lie but at least he then wouldn't wonder why she too did not appear on the map.
