I'm not sure if I'm missing something here, but I did the quest in it's entirety for the most part, and I took the kid on the ship with an updated log saying something along the lines of "Perhaps we'll be able to cure her later".

Cool, figured this would be at the end game, but no where did I find anything that activated her "cure". She just sits in the corner, standing/sleeping.

Has anyone else gotten different results?
