Posted mine, and still sort of tweaking. Sorry for the lengthiness of it. There is a lot of backstory coming out, now, since the Romulans are very central in Kim's life. A lot more than what I can tell in just a few pages, so I might write a longer version offline.
This is more than just a simple security breach for Kim. This is a life-changing event.
Essentially, Kim is finding out that when she lived on Romulus, she might have chosen the wrong friends. Other things going on that may come in later is that it's looking like Taris tried to have Kim killed. Whether it was on purpose or not, we don't know, though it may have something to do with an alliance with Donatra.
After Kim's disappearance in 2387, Ynala became a well-loved governor of an outer colony, and then was given a Senate seat by Taris herself.
So many questions for her now: Did her Romulan wife betray her? Was there something more sinister behind Vaihuu's conception? Did Taris try to frame Sela for Ynala's murder to pit the Hvallis against Sela? Or, did Sela kill Ynala on purpose with the intention of preventing her from challenging her ascention to power?
Suddenly, Kim is questioning whether she misjudged Sela, or if Sela is a different animal altogether. Either way, it's the first time in her life she doesn't want to kill her.
Regardless of those personal truths, in the eyes of even what little allies in the RSE she had, she now looks like a traitor, especially with Taris escaping under her watch, and the only way to exonerate herself will be to find Taris and kill her.
I might post another from Vaihuu's perspective, since this is also a life-changing event for her.
