Haha!
In all of the years that I have been watching this show and paying attention to trivium, this is one trivium that completely missed me... Majel Lee Hudec Barrett Roddenberry wrote it! Or part of it, The portion that involved her conundrum.
At some point after "Fascination", she apparently had gotten married to a man named Jeyal (Michael "Kang" Ansara), a Tavnian.
Who had promised wonderful things despite his race's history of separating the sexes until the age "of ascension". A promise that he instantly reneged upon after he "took possession" of her, which is about the best way you can describe Tavnian marriages. Not unlike certain marriages on Earth. In fact the concept of "the wife as property" was only discarded recently in our history, and at that, not completely. There are still some cultures that adhere to this concept.
Meanwhile, Jake Sisko Is standing in his regular spot which he used to share with Nog, "Musing" over story ideas when he notices a very alien and enticing Meg Foster step onto the promenade... they share a brief eye contact, which tells us a lot about what is going to happen.
These two stories dance around each other, not really touching.
But in a way the stories are similar. Jake was simply looking for ideas, Luwaxana was looking for shelter. Onaya (Ms Foster) attaches herself to Jake with almost unwarranted interest, promising fulfillment of his writers block issue, while Luwaxana seeks comfort in Odo. But there are also things that Onaya wants from Jake, while Odo has actually found within himself a little bit of actual affection for Luwaxana. But we know that this has always been the case ever since "The Forsaken", where Luwaxana promises to give him something that he will appreciate.
Onaya turns out to be connected to the histories of several Federation worlds, including Earth, in remarkable ways. She needs something from Jake, but she actually provides Jake something that is very difficult for a writer or other content creator to obtain: inspiration. But the cost of obtaining this is way too high.
This very short interlude between Jake and Onaya tells us a lot about Jake that we never really knew. Mainly, that he is in fact a very talented writer. Which was the last thing to expect especially after watching the first season of the show, where he is just a kid, flicking Sand Peas with Nog upon unsuspecting aliens, or dousing couples at the replimat with "Garanian bolites".
In order to extract Luwaxana from an unfortunate alliance, Odo has to form one with her himself. But that is not the end of it, he must provide convincing reasons why he actually wants this.
And this is something that he does in a very remarkable speech. This is despite the fact that we know that he loves Kira, which Luwaxana knew even before he knew it.
Unfortunately this is the last that we will see of Luwaxana in any Trek. As far as Onaya in concerned, she turns out to be not what she appeared to be, and also leaves the vicinity. She leaves an almost tangible scar on Jake, while Luwaxana does the same for Odo.
Neither Jake or Odo are quite the same after these encounters.
