Not sure, I would assume so though at this point everyone is adamant against it other than Darja. I really don't like the princess character, she seems shady, so making Darja a real princess dragon maker is supposed to need some royal blood. Let's see how much...
I have a question myself. I really don't want to replay the game to see, but what happens if you don't use the breaker on Naho? IIRC if you make her your primary consort she runs away or something, but what if you don't break her, don't make her the prime consort, and then play this patch? Is she just not as messed up and still lives like a pet? Out of all the girls who's lives you make better by ruining them, she's the most pitiful, so I kind of want her to have a nicer story arc than she has now.
