but unfortunately nobody has yet written me the fic where Ekaterin gets to have a wild fling with Naismith.

I would never be the one to write it, but if I weren't writing it, Ekaterin is doing work for her PhD on some space station somewhere (because it's a lot easier to keep plants from infecting other plants with their wily pollen if you can just open an airlock if you need to), and the Dendarii come through, and Miles is wandering the halls and has a mild allergic reaction to alert him that there's Barrayaran botany nearby. And there's a woman there, dressesd like someone from home, but she's berating him like she's one of his officers because he's messing up her project.

I don't know how Lord Vorkosigan gets into this, maybe Ekaterin goes home and looks up Cordelia at Admiral Naismith's suggestion.
