"What do you need boy robes for?" inquires Madam Malkins.
"I'm sometimes a boy," the girl explains.
"Because if muggles find out that pointy sticks are used by magic people then they will probably try to snap pointy sticks and also kidnap people in the night while they're sleeping," he responds. "Which was three hundred years ago so I'm not sure the statute has much of a place anymore but I'm pretty sure it did."
"Then I'm not rubbing the fact that magical people are crazy and don't want spaceships in their faces either," she retorts, grinning. "Besides, they gotta make up their minds, either Middle Ages muggles were a threat to them from whom they must hide or they can take twentieth-century muggle technology from their hands, can't have both."
"Thanks," he says, moving to do as such.
To Sadde: "You're a witch – wizard? – anyway that was point two as well, and a metamorphmagus, and what I said just now, people wouldn't usually say that, and you also care about the statute." Pause. "Add a sixth, the memories thing, I think you're a bit more – definite about that than most people."
Anthony pauses, thinking, then says, almost as if he has a checklist: "Dark. Having some weird link to snakes of some kind. Typically hate muggleborns, or anyone who isn't pureblood. Sort of – uncaring about what people feel. Use bribery and extortion to get what they want, and they want to rule the world for the sake of having power."
"No, but he had–" Anthony pauses, looks around, and then continues in a lower voice: "He had like thirty direct followers in his inner sanctum, they all had their families indoctrinated, pureblood Slytherin families have high numbers of Slytherins who then try to indoctrinate others, and there are large bits of the population who were sympathetic to his goal of killing off muggles and non-purebloods?"
He nods. "Mum's not usually too fussy about when guests come around, she keeps the house sort of tidy as a general principle, so I think it'll be okay? And she likes talking to people from different backgrounds, especially since she's not really used to talking to muggles?"
"It can be quite disorienting at first, but it's perfectly safe."
She shows them the way to the public floo system and explains about the steps involved in the mechanism – grab a handful of floo powder, throw it into the flames and wait for them to change colour, step into them, and then enunciate the name of your destination clearly.
She tells them the floo address for the house.
He shows her the clock! It has some fancy animation on the hour if you set it up to do that – which they usually don't, because it sounds like it could be distracting – but they were fashionable to get a few years ago in his mum's social circle – and then he shows her the hallway and what it looks like outside so she knows what the outside of the house looks like…
The stairs seem like they go quite a ways up, to quite a few different floors, if she looks up while they're in the hall.
"I don't think magic usually makes people, though. I'm not saying it's totally impossible – but I'm pretty sure if they were people, it'd be the sort of thing people know? They're not exactly badly treated, they're usually considered antiques and stuff, but I'd expect to know."
"… The person who produced the magic for the portrait, is what I was thinking…" Blink. "This is not actually, you know, what it is – I haven't asked, it hasn't made me ask this, I just treat them, uh, as I would treat a magical portrait? Try to be polite, they vary in personality, I'm related to a couple of them?"
"… Right, uh, they–" Pause. "It's– uh. The Killing Curse, Imperius Curse and Cruciatus Curse." He looks around, possibly checking that nobody's listening, and says, "First one is, I think, clear, second is – you can control people to do what you tell them to. Third is for torture."
"That was me trying to be ridiculous – they honestly think you have impure blood because you're from a muggle family, and muggles aren't magic so they don't have the 'right blood', but purebloods do, so they think you're not as good literally because your bloodline isn't magical."
