Amelia had been mildly interested in the answers of her classmates, mostly because it gave her greater insight into how they felt about magic and their motivations for using it. Most of her classmates had chosen charms that were more practical, and also those which were taught at a lower level. She did not blame them for their choices; they were logical choices for those who engaged in duels or were out late at night.
Amelia had chosen the Fidelius Charm because secrets were her motivation. She worked hard to keep herself private, removed from the world. The Fidelius Charm was her favourite because it gave in to the same concept. It ensured that if she told someone a secret, it would literally go with them to the grave. It prevented the worry that often went hand in hand with sharing some part of yourself with another person.
Although she had been intrigued by the answers of her classmates, Amelia was pleased to move on to the practical part of the lesson. She was somewhat disappointed to find that the spell of the day was Mobiliarbus, for she had learned this spell before, but she supposed that for the first lesson of the semester it was somewhat appropriate. Also, she could probably stand to improve her weight tolerance for the spell, as she had only moved pebbles and the like when they learned it in their fourth year.
Amelia pulled a book from her bag on the floor and set it on her desk. Taking her wand from the waistband of her uniform-dictated skirt, Amelia pointed the wand at the book, mimicking the movement of Professor Lupin's - ahem, Khaat's - wand. The same bright light enclosed the book and she directed it across the room, above the heads of her peers. Amelia realized while doing this that Khaat had been correct in saying that heavier objects were more draining – books were nothing like pebbles. When she felt her resolve waning, she allowed the book to drop in altitude and come to rest on the desk of Albus Potter.
