So they wouldn't be talking about the history of Halloween. Sad. Halloween excited Maddie, because of all the free candy, but she could deal with talking about the Battle of Hogwarts. It was a really big important part of their history, and of course she'd grown up hearing all about it. "There were over fifty people that died, some of them children!" she said, raising her hand and looking at the professor with a horrified expression. No matter how many times she thought about children her age fighting and dying in a war, it still freaked her out.

Also...

"Wasn't there a Battle of Hogwarts, because Voldemort figured out Harry Potter was in the castle to destroy the last of his horcruxes?" she asked. "What's inevitable mean, Professor?" Was she asking if they thought the battle HAD to happen or not? Maybe had heard the word, but she hadn't used it much at all. Maybe not even once in her life.
