Victor inspects the rat.

Muninn also inspects the rat.

"I get a lot of my cousin Dudley's old things," says Victor, "but I had to get all new magic things because Dudley's a Muggle and didn't have any."

"Mum sorta had to raise me on her own and she doesn't make a lot of money all year. I'm gonna use magic to get rich, though. But I always knew I would."

"...You always knew you would make a lot of money with magic? How?"

"So you know how kids always have accidental displays of magic? Mine were flashier. I'm a metamorphmagus. Means I can basically look like whatever I want."

"Wicked! Show us something!"

"How about this?"

...Victor blinks. He is not sure how to respond to this.

Ron's startled. "You can change even that?"

"Mum says the first magic I did when I was one year old was shift like this," he explains, morphing back. "So I never really... you know, decided to just be a single gender."

...well, okay, that seems fairly straightforward.

"So wait, you're not a boy?"

"Right now I am. Some days I won't be."

"Can you change other things too?" he wonders hesitantly. It's an interesting power.

"Yeah, pretty much anything—" And now he has chameleon eyes.

He yelps.

"That's interesting," says Victor.

He giggles and is back to regular human. "I can't turn all of myself into an animal, though. Just bits. Not my brain, for sure."

"Really? Why not?"

"Probably 'cause if I did then I'd be that animal and wouldn't be smart enough to go back."

"But animagi can do it."

"Yeah and it's a special type of magic and they don't even get to pick the animal they turn into, it's not just regular transfiguration."

"I don't know what those are," says Victor.

"There's a type of magic you can learn which lets you turn into an animal but still think like a person. People who can do that are animagi. You don't get to pick the animal, though, and it's really hard to learn, and if you're an animagus you have to register your animagus form with the government. If you learn it you don't need to use a wand to do it and it's really easy, though."
