"And the old Transfiguration teacher was an Animagus!" Dimitri told Zhenya, reading to her from Hogwarts, a History.
Her eyes widened, "What's thaaaaaaaat?" she asked. She thought, was it a monster? A job?

Dimitri laughed and said "It's when someone can transform themselves into an animal. She was able to transfigure herself into a cat," he explained.
She was very impressed. "Are you an Aminonin?" she asked.
He laughed again, "It's A-NI-MA-GUS. And no I'm not, it takes a lot of practice to become one," he said.
"I'm going to be an owl," she said to herself.
