"Maybe they want to be able to have jobs besides banker." 

"Why don't they?"

"Maybe they can, and just don't want to, I haven't met any. The books don't say that, though. I think wizards don't hire them for other things, and they don't have their own economy for some reason."

She looks at Scott's father.

"I don't know any wizard this interested in goblins. I can tell you who was Minister during the last goblin rebellion, that's about it." 

"I'm gonna ask a goblin," she decides.

"I hope you two find a friend who can stop you. You can't just fight the entire wizarding world on every little thing."

"Sadde, can we fight the whole world together?"

"Of course we can."

So Scott tells Sadde about all the magical beings and beasts he's been reading about, and he tells her very excitedly that Hogwarts has ghosts, so they'll have a chance to figure out how those work (the books don't actually say).

"Ooooh that is so cool I didn't know ghosts were a thing wait does that mean souls exist is there an afterlife?"

"The afterlife exists. Ghosts reject it, in favor of staying on Earth. Usually, they have unfinished business and can't move on."

"That's what the books say. I want to meet one."

"Me, too. What's in the afterlife?"

"No one knows, people don't come back."

"We should talk to a ghost, my dad doesn't know anything." 

"Well but will they know?"

"Not for sure, but I think I should talk to one before looking for a book, it's not in one of the ones I have." 

"Yeah, we'll talk to them when we get there."

He seems content with that. 

Also biscuits. Biscuits are an important factor in how content he is. 

"What other things did you learn?"

Does she want to know about the history of wizarding transportation? Scott has notes. 

Yeah!

They have winged horses! So cool! 

Here's Apparition, works like so, needs a license. Here's the Floo Network and the messy legislative process behind its ubiquity. Here are broomsticks, which they get to learn how to fly as soon as they get to school! Also here's how wizards started using them.

Awesome! She can't wait until they can get on brooms.
