I'm surprised that Evelyn was able to walk out of the temple without any priests stopping her. If there was anyone around, they'd have told her that she outranks the crown prince.
The temple's really been over relying on her though. It seems like the saint gig is only something you do for a decade or so before retiring to get married, but they haven't been letting her do that. She was so talented that they neglected to raise her successor or allow her to have a life. If they want to get her back to being the saint, they'd better make some concessions.
