Ivan must be drunker than he thought he was. He could have sworn he knew his way around Vivienne's parents' house, since she wanted to introduce him last week and showed him the place, but maybe they have a... secret... upstairs... bar? where Vivienne's room is supposed to be? And most certainly was last time he checked? He's never going to find the sweater she sent him up looking for here, anyway. Why is there a secret upstairs bar in Vivienne's parents' house?
"It's creepy," says Ivan. "Stalas is bad enough, at least he's taller."
"Annoying you is a bonus. I wanted to see the dwarf. And I missed Ivan, of course."
He laughs. "Yes, of course, I'll just go get lost in the mysterious cave, never to be seen again."
"True. Then again, so would loitering in the bar and following you all out when you leave."
"Think I can get off-planet without anyone noticing? You did all come from Barrayar, did you not?"
"We came from my girlfriend's parents' house. Maybe you could get off planet without anyone noticing if we didn't warn anybody and nobody at the party saw count 'em one two three of Miles leaving when only one came in."
"Well, he'd have to emerge from the cave instead of never being seen again, first, but it's an idea."
"Unless it turns out the space warps so that the cave opens into the lake on the other end, and the giant squid eats him."
"I think Bar would have warned us if the giant squid were prone to eating people."
"Well, then I'm not telling you, because ImpSec is off my back for once and I'd like to keep it that way as long as possible."
