She well-tempers the piano, and plays one of her relatively few memorized pieces (there are, in fact, a lot of them, but fewer than musicians of her acquaintance acquire for their repertoires) to make sure it's how she wants it.
The next morning, she draws Miles a diagram of the cascade braid and lets him practice it until he's got it down and she can wear it out. Cordelia mentions that she has invited Gregor over.
Linya tries groats with maple syrup on them for breakfast and, unexpectedly, loves them. (She does not try ethanol in any form, nor animal meat, this early in her residence.) She gets her pen to connect to the Barryaran comm networks. She meets, by comm-call, the Vorkosigan family accountant Tsipis, with whom she gets on absolutely famously; after fifteen minutes they have an enthusiastic agreement to talk thrice weekly so he can teach her economics and keep her up to date on how he's doing with errands for her nascent pen development business - sourcing materials and tools for her prototypes, materials and tools and manufacturers and programmers for scaling up when she has a solid consumer version.
She starts teaching herself the local form of Greek and has another bowl of groats in the dimness when there's nobody about but the night guard.
She slips into bed with her husband contentedly and snuggles up and goes to sleep.
If and when, the words will - if they go with the most common variant - be: "I, [full name], do take thee, [full name], to be my spouse and helpmeet, forsaking all others. I swear to stand with you, united in love; to give aid where needed, and accept it where given; to guard your honour as you guard mine, our lives intertwined, for as long as we both shall live." Charming, much more sentimental than the "genome in a pretty package as a gift for you" language of the one they've already had. She does not think she wants to recite these words this week, but at some point - perhaps.
When she has finished reading the book she takes it back to the library and attempts to figure out where it is supposed to live. Eventually she divines the organizational system, puts it in its spot, and consults the time. It is nearly noon.
She's hungry, but should probably not start lunch without the anticipated imperial guest. She goes and loiters on a couch near the entrance and studies Barryaran Greek. (She knew Ancient Greek already, but this helps surprisingly little.)
The man himself follows.
Tallish but not towering, with a serious face and slightly untidy brown hair, dressed semiformally in sober colours that correspond to neither of his official uniforms. Very unimposing, for an emperor; perhaps that's on purpose.
When he spots Linya on her couch, he gives her a cordial nod. "Lady Vorkosigan."
"Your marriage to Miles presents several... interesting complications for me on a political level," he says. "But on the personal, I'm glad he's found someone, and I hope the two of you suit each other. I'd like you to know that I don't intend to hold you to account for any trouble you cause here by the mere fact of your existence."
This plan of action having been formed, she turns to lead her guests to the table in question - a medium-sized one that lives in a lesser dining room, currently supplied with four place settings arranged in facing pairs.
And then, when everyone is winding down and Miles is occupied with a final bite but Linya is not, Gregor looks across the table and says mildly, "So. Are you some sort of spy or saboteur?"
"I have no marks that would be associated with someone physically introducing anything dangerous or spylike to my person, my personal electronics are all custom-programmed to paranoid security standards and therefore highly unlikely to harbor malicious software placed there without my knowledge, I am not missing any time - and I would notice a gap in my journal notes - to account for what would be unusually difficult attempts to psychologically or psychiatrically manipulate me, the strategem would be completely unprecedented on several levels, and I have no particular objection to ImpSec reading my every offplanet communiqué, double-checking any designs for products I intend to distribute, or, in the one case, sleeping in my bed - so no, I really don't think so."
"But, again, if my word on the matter doesn't suffice, I did not exactly land on Barrayar expecting minimal suspicion or the ability to coast without any attempts to assuage it, so you will not ruin my weekend plans if I need to have another chat with Captain Illyan or something."
"Noted. But I don't think ImpSec is going to need to watch you much more closely than they'd watch any Lady Vorkosigan. As explanations for your presence go, 'Miles did it' is an extremely compelling alternative to 'the Cetagandan Empire decided to package some subtle disaster in the form of a haut-wife awarded to a low-level intelligence agent with good political connections'."
"Almost certainly, but they're not the ones I worry about," he says. "Would-be assassins are a problem for security people. My problems are a little less direct. I can foresee three obvious categories of trouble, once your presence is widely known: quibbles about your immigration status, quibbles about the validity of your marriage, and spite-motivated voting shifts in the Council of Counts. The last problem is not really something you can affect, but the first two... well. You do exist in something of an ambiguous state, at the moment. Taking an oath of fealty as Lady Vorkosigan would go a long way toward shutting up the dissenters. It isn't strictly a prerequisite to remaining on the planet and married to Miles, but it would clarify some of those ambiguities, and it would be something to point to when people complain about your planet of origin."
"Sparing you a few hundred years of complicated legal history, the most appropriate for your situation would be one that has you swear no prior claim binds your loyalty - meaning, any other citizenship you may hold does not conflict with this oath - and then take oath as my vassal, which is another few hundred years of complicated legal history all by itself, but in summary it means that you agree I am not just the Emperor of Barrayar but your Emperor in particular, and will obey my laws and my orders. And in accepting your oath, I promise you the protection of a liege lord and Emperor, which means that if anyone threatens your safety or well-being it is my job to make them stop. Again, summarizing over the intricate details."
"The only ongoing interest Cetaganda has in me is that my constellation geneticists would probably like to continue to receive copies of my medical records, in case I turn up with an obscure allergy or something that they can rescue the next generation from. But I think I would want to better know both you and the intricate details in question before making an oath - if I am being asked to consider it any more personally involved than 'these are the magic words that make irritating political opponents less irritating and oppositional'. Not that I plan to make mischief or be particularly uncooperative, but in a context where oaths are taken with such deadly seriousness I'd like to be especially mindful."
"I like the composition of the Barrayaran ceremony very much, actually, unless there are marked differences between book and practice of which I am unaware. The way the couple marry themselves and the - sentiment in the vows, in contrast to what amounts to - 'here, have some genes; the phenotype, let alone any personal relationship, is more or less irrelevant beyond a wink and a nod'."
"They are not what you married me for, but they are technically what Lisbet offered you. Those and, by custom more than interpretation of the text of the offering, my genetics expertise. To be fair to our irritating political opponents, they may have a point about marital validity in the sense that the two customs share a name principally by historical accident. We should certainly at least discuss incorporating colorful groats."
"It's open to a certain degree of interpretation," she says. "I'm sure the book mentioned that it used to be a coded way of saying that the wife wasn't going to cheat on the husband and the husband wasn't going to tolerate adultery in the wife, but modern readings tend to be rather more open-ended... for me personally, I would say it means supporting each other in difficult decisions and helping each other find the right choices. But I'm Betan, so perhaps I'm missing something."
"The book did mention that, but since 'forsaking all others' is also in the text it seemed redundant if that was the entire point - unless, as is perhaps plausible, those composing these vows were rather obsessed with adultery. There was a footnote about someone attempting to use it as an excuse to arguably abuse his political power to protect his wife from what was either slander or substantiated rumor, the book did not opine on the veracity of the unkind words in question..."
"I think part of it might be - trying to be worthy of each other," says Miles. "Because when you're married, you're not quite entirely separate people anymore. Things one spouse does reflect on the other one. So you guard each other's honour by acting honourably. Which leads right back to 'what is honour', I suppose."
"It's certainly arguable that being forsworn is at the root of all dishonor. But there are more complex cases," says Gregor. "If I had to boil the concept down to two oversimplified rules, it would be 'behave ethically and don't break your word'. Which, if not exactly a complete explanation, does have the advantage of putting things in more galactically accessible terms."
