"Got it," says Trouble. "Can I hear your list of bright ideas?"

"Check speeds, check healing tolerances, check if we can control the order of operations at all, figure out just how tiring it is and how many times in a row we can pull it off, you already checked if we come with knowledge of how to move around in morphed bodies but I'll double-check with the butterfly, same with thoughtspeaking, it made some noise so I'll want to see if we can cut down on that for stealth. That's what I've got so far."

"Yeah," says Trouble. "And I can't thoughtspeak when I'm human - I tried. Forgot to say."

"Good to know. Pity, that would have been tactically precious."

He shrugs. "Yeah. Oh well, I guess."

"Yes. Let's go catch me a butterfly, and I can go practice with Andi supervising while you find Robin?"

"Sure."

"There should be some in the garden. Little drab ones."

Within five minutes, Trouble has a little white butterfly caged in his hands. He brings it to Bella.

She accepts it, acquires it to keep it from escaping, and carries it in in case Andi wants it too.

Andi does want it too!

"You guys are gonna be a cute butterfly," says Trouble, admiring the original.

"Yep!"

"So I guess we'll see you later, Trouble?"

"Yep. Hug?"

The twins play with the butterfly until he comes back.

He returns about an hour later, accompanied by Ethan and a map. A really good map.

"Hi, guys. It turns out Andi is some kind of morphing prodigy. She can include clothes, and control order of operations, and she's six times faster than me at the butterfly. She also figured out how to stop in the middle, but I can do that too, now."

"How about clothes, can you do those?"

"Working on it."

"I can't do just any clothes, they have to be pretty snug," says Andi, who is in fact wearing a tube top and leggings. "But they just sort of come along, if I want them to - not when I'm turning into Bella, though, then I want them to stay where they are."
