"What do you need boy robes for?" inquires Madam Malkins.
"I'm sometimes a boy," the girl explains.
"What?"
"Look—"
"… If you go doing that I probably want more details on what you mean by 'fix'."
"Well, you know, make them not be evil nor hate muggleborns and half-bloods?"
"The whole world, meaning the whole magical world? And – 'evil' is – like it's really clear in my head what's evil but people seem to struggle following that and have different opinions so there is probably something going on."

"It does, and a lot of people fail at that, but that is – probably a good first step, if 'hurting' is clear?"

"He's nice and he knows a lot of stuff and I haven't even interrogated him much yet!"
"It's fine," he says. "I don't usually get to explain quite so much to people unfamiliar with the context."
"Just outside a small city in the south-west? I don't know if you'll have heard of it – Wells?"
"Wow you live even farther away than we do. How'd you get here?—was it by brooms, that'd be so cool if it was brooms."
"It was by floo!" he says. "– You might not know what that is, uh, throw powder into a fireplace and arrive at the destination you say?"
"I wasn't questioning the ability so much as wondering about the method. How exactly does that work, you throw powder in a fireplace and then...?"
