Teddy sat, scribbling a rough drawing of the girl he had seen by the lake. It started animating itself almost immediately after he lifted his quill from the parchment. The girl kept tossing rocks into the lake, then turning to face him, before going back to throwing more rocks, to turning to face him again. But she was faceless. Teddy stared at his drawing and sighed.

Professor Bell, the DADA teacher, was reading out of one of their textbooks about werewolves. They had spent a couple of lessons on werewolves, and Teddy couldn't stand it - everything Professor Bell was saying made Teddy's father seem like a horrifying, man-eating monster.

Suddenly, Teddy jumped to his feet and shouted, "My father was a werewolf! He fought in the Second Wizarding War! He helped defeat Voldemort!"

The class was completely silent. Some of his classmates stared at him, obviously shocked at his words. Others avoided eyecontact, feeling sorry for him or feeling guilty about what the teacher had been saying about werewolves.

Professor Bell looked at him sadly. Alright, 'sadly' was a gross understatement - she looked as if she were about to cry. After a couple of minutes of silence, she whispered, "I know. He was my teacher." The whole class stared at her as if she had sprouted another set of arms. She nodded quietly. "He taught Defense Against the Dark Arts for a little while when I was a student here. He was the..." She paused, looking upwards and blinking. After a little while, she continued. "He was the best teacher we ever had."

Teddy stared at her, tears starting to well up in his own eyes.

Suddenly, she picked up the textbook she had been reading out of, walked to the rubbish bin and dropped it in. Then she returned to the front of the class and asked her stunned students, "Who knows the difference between an animagus and a werewolf?"

Teddy's hand shot up. She smiled at him and nodded. "An animagus is a wizard that elects to become an animal. A werewolf has no choice."

Professor Bell's smile grew. "Exactly. And who knows how one becomes a werewolf?"

The class was silent. Teddy didn't know. He had never even thought about it. He supposed that he had just accepted it as part of his father, as if it was hereditory, like being a metamorphmagus.

The professor looked around the class before saying softly, "By getting bitten by a werewolf."

The tears that had started to fade away came back, falling steadily.
