The question there is if you get locked into what you were when you first did the quest as a male Roegadyn and then fantasia'ed into a female Lalafell, what would happen with the cutscene?
Would you be a male Roegadyn or a female Lalafell?
If it is the former, it goes against their view of fantasia - it can't be a what you always were if you appear as a different race/gender in a cutscene.
If it is the latter, what if you were wearing something with the appearance of something you can't wear as your current race? Such as an outfit locked to male or an outfit locked to Roegadyn.
