She giggled a bit at the mention of cleaning spells. She supposed she might end up in the same boat as Gus, only being adept at a handful of useful spells. Billie didn't think of herself as the smartest kid. After all, most others her age could already read very well and had been writing for years before she could. She just hoped she didn't fail out of Hogwarts and become a disappointment to Gideon. Maybe he wouldn't want her around anymore after that. That was something she didn't think she could bear. "Yeah, I'll jinx everyone!" Okay, maybe that wouldn't exactly make Gideon happy, but she didn't realize that, yet.

"Did you get to see dragons in Care of Magical Creatures?" Billie suddenly blurted out at the pair of them, her own excitement about the subject not allowing her to think through what she was even saying. "And nifflers? I have a niffler friend. Her name is Ginger, and she's Mr. Scamander's pet. I hope she has babies one day 'cause I want one of 'em."

She quieted long enough to hear that creatures classes helped with wandmaking, and she tilted her head slightly. "Maybe if I'm real good at it, I can help you get your wand cores, okay?" Which could be a disaster, but all she wished to do was help repay Gideon for all of his kindness.

Her eyes widened a bit at the mention of kelpies. Even muggles told tales of them. "Yeah, that might be useful."
