Nooo, don't go otter! Leah was staaaring at the thing when it disappeared. She turned her attention to the Professor as he explained what they were learning today. Something that Dark Wizards could not do... she thought about the Patronus that was present in the classroom just a moment ago and a smile stretched across her face. She was SO excited for this. Unless she was a Dark Witch herself? No way.

A hundred things about Patronuses appeared in her mind at the question. She picked one of them and raised her hand. "A Patronus can be used to drive off Dark creatures," she said. It was like a guard. But much cooler.
