The one spoiler I want to know is, what is with Flonne? Has she been demoted? Is this prior to her becoming an Archangel? Can she switch between forms? What?

In a way, I like her both ways, but I know a lot of people have the "she got demoted because of D4" theory... but honestly, I dislike that one, if only because it makes no sense development wise.

Why spend three games, including one of them with having her study to become an angel again as a subplot, building up Archangel Flonne, only to have her demoted off screen? It honestly seems like a huge waste of plot.
