^More like the writers just fucking forgot about her. Like, completely; I've been going through the NPCs checking their post-quest dialogues and so far you'd be excused for thinking she got deadass Unpersoned in Inazuma or something because nobody seems to remember she even exists. Even her family.
Also keep in mind that's shortly followed by one of the most glaring asspull plotholes in the entire Archon Quest so... yeah. Lots of really half-assed writing in that part.
On the upside, the Shogun does speak very highly of her in her voicelines.
