Congratulations, Bull. You've just unlocked Hermione's true passion: talking about elves and how unfairly they're treated and how awesome they are and elves in general.

She's happy to listen to anything Bull can tell her about elves and their history, but he doesn't exactly leave off on a high note. More than a little aghast, she starts for a moment before asking, "So they just... kicked her out? Because she's a mage?" That frown returns as she looks down, feeling a little sick.

"But... what about her family? Her friends? They just turned their backs on her because she happens to be able to use magic?" Granted, she supposes there is a fair amount of danger in keeping an untrained mage around, more so than an untrained witch or wizard, but even then, wouldn't setting up magic schools be simpler?

"I don't-... don't understand. It sounds so cruel."
