"Did you want anything to eat, Sadde?"

"Sure!"

In which case he brings out the crisps, and gets the tea started.

"Did you know you're a Metamorphmagus? That's what it's called, the thing you do where you're a boy and then you're a girl. On the outside, I mean."

"I started shifting—morphing?—when I was one. I didn't know what it was called, though, Professor Flitwick told us."

"What else can you do? Can you turn into animals? Maybe that's why they don't like you."

"I can turn bits of me into animals, not all of me."

"Can you fly?"

"No, I looked it up, humans are too big and clunky to be carried by wings."

"Can you make yourself less clunky? Why are we too clunky, is it all the bones and organs? I don't think it's safe to morph those away..."

"Scott, don't tell your friends to get rid of their organs."

He brings over biscuits and tea cakes while they wait for the tea.

Biscuits!

"I think it's all the bones and organs, and I can't morph them away even if I try. I can only do safe things."

"That's pretty convenient. There aren't a lot of good books about Metamorphmagic. Maybe you're all too different, but maybe none of them thought of it. You could probably make a lot of money that way."

"Oooh, that's a good idea! But maybe I should meet other metamorphmagi and ask if they're different, first."

"They're rare, but I can try to get you in touch with one."

"She can ask a professor." 

"Or she can ask a professor."

"Or both!"

He pours them all some tea.

"Sadde, Scott told me you're expecting Slytherin house already. Anything I can do to change your mind?"

"I didn't choose Slytherin, I just think I might end up there. Or Ravenclaw. One of those. Why?"

"Sorting is about where you'll do best; the more you like a house, the more the hat wants to put you there." 

"Right but why do you think I shouldn't be Slytherin?"

"Slytherin has been churning out murderers and terrorists for fifty years, thanks to one of its worst members. A Muggleborn won't be very comfortable there." 

"What happened fifty years ago? Why is being a muggleborn important?"

"Wizards are racist against Muggles."
