"Okay, that's less nerve-wracking. The painkillers I am acquainted with might not work while you are being a crystalline horror but they do not themselves explode."

"Crystalline horror," he giggles.

"I did not detect signs of, like, a vascular system in there."

"I'm made of normal flesh and blood most of the time!"

"Normal flesh and blood that crystallizes at odd provocations!"

"Well, yes."

"On noncrystallizing humans I could do the chip and the wings just about risk free - although you'd have to commit to the wing design and be very sure about it compared to a demon let alone an angel adding extremities - and I am also a fully qualified medical demon."

"What wing designs are there?"

"Well, assuming you want them to work, you've basically got bird kinda wings and bat kinda wings -" Cam pulls up the catalog he selected his own wings out of.

"Oooh, I am so tempted by wings," says Tiro. "I shouldn't be this tempted, I just exploded like yesterday, normally that puts me off risky things for a while, but wings!"

"Will it slow you down if I mention it takes a while to learn to fly and you may in the interim crash?"

"It should, but it doesn't appear to be."

"Should I be enforcing some sort of waiting period?"

"Maybe. But until we know whether I can have wings, we don't know what the accessibility considerations are for where you put your house!"

"This is true!"

"It would probably be sensible to just put your house somewhere reachable without flying and then wait until I'm used to the idea before I decide whether I want to try getting wings..."

"Yeah, probably." Nudge. Now the house is a short flight of attractively tiled stairs away from Tiro's.

"Nice stairs!"

"Thank you I stole them from a park."

He cracks up.

Wag wag.

Giggle.

"Any more things to change about this mountain range before I go place it?"

"No, I think it's perfect. Where are you going to put it?"

Cam pulls up a picture he took from the air of the area. "Along here, I think."
