Unlike a demon I can't do format conversion, but - She offers an object which is presumably some kind of recording.

"Thanks!!!!!!"

You're welcome.

Amriac curiously converts the thing and puts it on. It's weird.

"Huh. - yours is nicer, despite there not being much reason for demons and humans to have the same musical taste."

"My Earth didn't know about daeva for a long time but daeva knew about them, and demons in particular have been able to swipe their stuff, especially since writing got popular. And daeva are psychologically pretty much human-range."

"You seem a lot nicer."

"Humans eventually suck less and then a while after that get very goody-goody, Don't tell 'em about transfiguration."

"Is that the thing with the kittens," says Amriac. "That's just wasteful."

"It's not like there's a shortage of kittens. Cats have large litters."

"Well, I bet demonic kittens would work just as well."

"Yeah, probably, but then we'd have to explain demons."

"Oh, couldn't you just say you made stupid cats by magic?"

"That'd be pretty impressive magic, if I did it from scratch instead of just making a normal cat stupid. I guess I could say I was trying to practice a new charm and now I had hundreds of brain-damaged cats, did the department want to use them."

"Why would that be impressive?"

"Some stuff is harder for us to make than others...something uniform throughout is pretty easy, something temporary is pretty easy, something biological and alive without ongoing magic intervention is hard, can't do food..."

"Food? That's kind of random."

"Magic is not a very well-understood field. Want to go back out to the lake, if we can put off shopping as long as we like?"

"Sure." She traipses, alien music still crooning from her speaker.

He lets the rock circling his brother's head fall to the floor, and then follows. 

"So, um - what's a black hole -"

"You know how things fall to the ground because the planet is really heavy?"

"- yeah -"

"Black holes are heavier."

"...ah."

"People make jokes about demons holing planets - planets with humans on, I mean, in Hell it's just a few weeks' work to make a new planet if you wreck an old one - but nobody'd ever done it."

"No one's going to be - inspired to, or anything?"
