Her parents are kind of insistent about feeding people but not so insistent that she can't mostly handle this by not translating all of the insisting. They also talk about how Catherine and her husband are going to support themselves, and how and where they're going to build a house for themselves and the children, and everyone is mostly very sure that everything's going to work out, even if it might be hard feeding so many extra people for a bit.
They build a house. It's not elaborate, but it keeps the rain off for most of the year and the snow off of them in winter, and it means they have their own space. She and her children help with harvests and planting, and her family is willing to let her husband mostly help with animals. This is somewhat less objectionable if he can also be called on for repairs and construction when unfortunate things happen to any of the nearby buildings. After a while most of the extreme gratitude wears off, but so does most of the surprise at his various quirks, and they're left occasionally acknowledging that Catherine married a very strange man who in any case keeps her fed.
The Emperor is missing. There's a peasant revolt in the south. Another in long-occupied, stubbornly Catholic Ireland. Scandinavia's regent is its spymaster, a concubine she once knew, who orders what's left of the former royal family into hiding. They receive reports of civil war on the mainland that differ wildly in their specifics.
She learns to cook and sew and how to tell if plants are healthy. She gets pregnant again, because they're slow and they've had years and years to figure out how to make things not hurt, and this is sort of an obvious consequence. She learns new stories and dresses them up in poetry. She finds someone who knows French and learns it from them as well as she can. Her older children express that they will leave home as soon as they're of age. Her younger children occasionally ask her to tell them of fairy, and how they will live when they return to it.
And so they wait, together, season after season and year after year, for someone to tell them whether they have forever.
