He shrugs. "Public transportation's pretty good."

"Where do you live?"

"London! In a teeny tiny apartment in Walthamstow."

"Oh, so it'll at least be easy for you to visit Miranda. What about you, Willow?"

"We live in Oxford, mum teaches there."

"Sadde, if you want to come over and use our Floo to get wherever else, Renée won't mind."

"I don't have anywhere else in mind, other than probably visiting Karen. Although we could all spend Christmas Eve together! Except for Willow who'll be being bored out of her mind in France."

She sticks her tongue out at him.

"We do family stuff Christmas Eve, I can't come."

"Maybe! Um, Boxing Day?"

"Oh, I won't be there that day."

"I pretty much have no plans at all, usually mum and I just exchange small gifts and such but that's mostly 'cause muggles don't typically want to befriend me."

"And you haven't turned any of them into your project like the Slytherins are?"

"I never stayed long enough in any given school for that to be feasible due to Hulk incidents."

"Remind me what Hulk is."

"Hulk is a character from a comic book, and a Hulk incident is what I named all incidents where accidental metamorphmagic was bad enough that I had to leave school."

"...What's a comic book?"

"Okay I feel like this was a personal oversight," Willow says. "It's like a book, except instead of words describing actions and locations there are drawings, so each page of a comic book has a few panels that depict a character or a scene or a character in a scene with speech bubbles shaped like so," and she draws one in the air, "indicating what a character's saying."

"...That's weird."

"Nuh uh, it's super fun! And there is a particular genre, superhero comics, that's pretty big amongst comics in general because it's so much harder to write books about superhero action. The Incredible Hulk is from one of those! It's this scientist who's nice and polite but when he gets angry he becomes this big muscled green person who smashes things up!"

"That sounds really inconvenient!"

"It is! But there's a whole lot of story there and he's actually a pretty deep and interesting character."

"And that's the inspiration of the name 'Hulk incidents.'"

"Did you smash things?"
