"That wasn't supposed to happen," Hank says. "I mean, it was, but not at that scale."

"I guess you need to work on them a little more, then," says Serafin.

"Apparently," he says, pushing up his glasses again. "...Before I do, are there any shapes I should be accounting for besides various sizes of humanoid and dragon?"

"Yeah, I can do a bunch of animal and part-animal forms too. Wolf, cat, otter, orca, horse, snake, bear. I'm probably forgetting some, and there's plenty I haven't tried."

"Snake," he says despairingly.

He laughs.

"Oh, and some birds, too."

"How often do you use these forms?"

"Not that often."

"Okay," he says, "then I think I can make you a garment that will stay on most of the time. But making pants for a snake is beyond even me."

He laughs. "Fair enough."

"Ideally the pants would be opaque all the time when you're humanoid and invisible when you're a dragon," he says, scribbling at his notes.

"Yeah, a dragon wearing pants would look a bit silly."

"What I'd like to do is arrange for the stretching to be evenly distributed so that the added surface area the dragon's tail provides triggers the invisibility, but I can see I'm going to have to condense the polymer matrix in order for it to get that far..."

"I have no idea what that means," he says cheerfully.

"He gets like that," Raven says.

"Clearly!" He grins at Raven.

She smiles back. "Your shapeshifting is really cool."

"Thank you!"

"Can you turn into anything?"

Shrug. "It's - complicated."

"Oh?"

"...If I say 'anything I want' you'll probably get the wrong idea."

"I don't think I understand," she admits.

"Yeah. Like I said, it's complicated."

She worries her lip for a moment. "Maybe Charles could help," she suggests.
