It would not do to leave Nikolai Vorsoisson out of his calculations. "I gather then that the retro-genes took, and he's in no more danger of developing the symptoms of Vorzohn's Dystrophy?"

A smile of deep maternal satisfaction softened her face. "That's right. I'm so pleased. The doctors in the clinic here in Vorbarr Sultana report he had a very clean and complete cellular uptake. Developmentally, it should be just as if he'd never inherited the mutation at all." She glanced across at him. "It's as if I'd had a five-hundred-kilo weight lifted from me. I could fly, I think."

So you should.

Nikki himself emerged from the house at this moment, carrying a plate of cookies with an air of consequence, followed by the Professora with a tea tray and cups. Miles and Ekaterin hastened to clear a place on the table.

"Hello, Nikki," said Miles.

"Hi, Lord Vorkosigan. Is that your groundcar out front?"

"Yes."

"It's a barge." This observation was delivered without scorn, as a point of interest.

"I know. It's a relic of my father's time as Regent. It's armored, in fact—has a massive momentum."

"Oh yeah?" Nikki's interest soared. "Did it ever get shot at?"

"I don't believe that particular car ever did, no."

"Huh."

When Miles had last seen Nikki, the boy had been wooden-faced and pale with concentration, carrying the taper to light his father's funeral offering, obviously anxious to get his part of the ceremony right. He looked much better now, his brown eyes quick and his face mobile again. The Professora settled and poured tea, and the conversation became general for a time.

It became clear shortly that Nikki's interest was more in the food than in his mother's visitor; he declined a flatteringly grownup offer of tea, and with his great-aunt's permission snagged several cookies and dodged back indoors to whatever he'd been occupying himself with before.
