Ultimately, a compromise on the algae is reached, and Cam goes out in Komarran atmosphere sans mask and flies around deploying algal populations accordingly, in addition to some air that will sustainably permit a gas exchange with said algae, and supplemental plant life. He is ferried to out near where the second soletta is supposed to be and makes it, complete with the small propulsion mechanism it needs to begin orbiting appropriately (since he cannot appear it already in motion). There are other incidentals (refueling a generator to save some of the nice scientists expense, making a small experimental arcology dome out of diamond to see if that works well) but the whole thing doesn't take that long. Cam is the happiest waggiest demon.
Right. Okay.
It falls to Miles to issue the press release about this. Partly because he's nominally in charge of this operation, partly because having Cam do it would introduce unnecessary complications, and - he admits to himself strictly in the privacy of his own mind - partly because he can't pass up the opportunity to attach the name Vorkosigan to an unambiguous good for this planet.
He takes what might be an unnecessary amount of joy in addressing the holovid cameras.
"Citizens of Komarr, you are the first to benefit from a newly discovered rapid terraforming method. A test run, if you will. Highly respected local experts assure me that the process has worked perfectly. The final round of air quality tests will conclude tomorrow at noon, Solstice time, and after that..." He spreads his arms benevolently. "Enjoy your new atmosphere."
When he boards the courier ship to return to Barrayar, he is giggling irrepressibly.
"I just told all of Komarr that they get to have air now," he says. "Of course I'm in a good mood."
"And now back we go. Yaaaay, seeing music. Is there someplace on Barrayar proper I can go to discreetly fly around? Possibly the radioactive location? I don't think flapping around installing algae got it out of my system well enough."
"If you want to fly around Vorkosigan Vashnoi, be my guest. So to speak."
Trip proceeds. It includes a pleasing quantity of demonic food, demonic Lego, demonic violin, and demonic tail-wagging.
Miles creates some truly astonishing edifices with his Lego. It is a great way to pass the time. And work out his Cam-related frustrations.
He responsibly teases Miles with merciless accuracy only when Cam is not present.
"The tail's not a draw, huh? You are staring at it because you want to know how it attaches to his spine?"
"Why did I even bring you on this fucking trip."
"No. You were very useful. I just wish your usefulness didn't come with unsolicited commentary about tails."
"You would rather your attention be brought to how conspicuously you stare at his, ahem, tail, in some other way? Let's see, what are the other possible ways you could have come by this information..."
"Also, you do still keep doing the melting thing, I'm honestly surprised he hasn't picked up on it by now. Unless he has and he's being polite. I don't know a damn thing about twenty-second century Earth culture, let alone demon culture."
He has been toning it down.
"Yeah, but you do still melt at him sometimes. And stare at his tail."
"The tail is cute," he defends, against his better judgment.
