The pacing on her quest seems shockingly good on paper. Her quest kicks in two weeks after she's joined or immediately after Lumia. So she joins, you get to know her, then you help her deal with her issues.
Then the charas involved in it appear again in the Wayfort, so a bit more reinforcement of her chara after Act 1 is over.
At this point you'd be getting to Lumia's quest, with her guest starring in it.
She even has a few bits here in there in other quests in Act 2 that are kinda interesting (helping you out in the cave of trials for the sharks and winter wolf freak out).
Kinda solid flow from playing it as a new game. Too bad this stuff wasn't there to begin with. She just needs another quest or two, really. More talk scenes at least.
