>>48438229She was Lillie's (and probably Gladion's) confidant and moral support when Lusamine was going insane, maybe even more of a mother figure than their actual mother. She was also Lusamine's confidant and close friend while she was going insane. She kept an eye on Faba and gave the Aether members someone to look up to in a different way than Lusamine, always smiling to the camera, and trying to make the best out of the situation. And she assists the protagonists and the special forces to stop the ultra beasts without skipping a beat.
She isn't explored at all, all of this is convenient for the player, but it still also hints at her carrying A LOT of weight and baggage on her shoulders, and she is either strong enough to not break or very good at pretending.
One has to wonder how she copes with it all, what she does in her free time. She does seem to be passionate about the ultra beast in a purely academic sense, unlike Lusamine who was obsessed.
There is enough about her to wonder and headcanon even if the games don't do much with her.
