There are some things that I don't understand about this quest, does it have to be done in a specific order or do I just have to let the trust, respect and affection rise to a certain point?

I think it's second, though I've just seen all the scenes and left. I know the Warlock quest similarly had a bunch of scenes, but needed only her affection to go past 100 to be concluded.

ive been asking about the kylira quest for a while. I completed each scene, yet i still cant complete it.
