"Hello, Ivan," he says brightly. "Care to come for a visit? There's someone I'd like you to meet."
"Mysterious top-secret doings which present no danger to your life or limb and which I will explain in full when you show up."
"Because you're terribly uncreative and the only things that I might regret coming to have a look at are the ones that result in me hopping home on one leg? Well, that's me wholly reassured."
"I asked Gregor if I could borrow you and he said yes. Consider yourself officially reassigned to Whatever You Say, Miles duty for the forseeable future."
"...whatever you say, Miles. Does this mean I'm begging off work now or merely that I'm turning up for dinner?"
Miles greets him at the door, just as suspiciously cheerful as he was around lunchtime.
Miles takes Ivan up to Cam's room - Cam has been pre-warned; Miles is not totally without mercy - and knocks.
"I swear on my name's honour that I did not have any reasonable way to predict that screwing around with some crappy chalk drawings in a public park would result in this," says Miles. "But anyway. Cam, this is indeed Ivan, on whose behalf I apologize for all the screaming, I actually didn't expect that. Ivan, this is Cam, who is very nice and has impressed both Illyan and Gregor with his general benignness, and who is going to accelerate the terraforming of Komarr with magic because he is a magical demon from another universe. Did you hear what happened to Cockroach Central? That was him."
"I heard, I thought it was - I don't know what I thought it was - you summoned a demon?"
"Yes, demons in general are apparently very scary, but this demon in particular is just adorably enthusiastic about public works projects," says Miles.
