If you can't choose to do what you want then power be damned anyone can do it and no one will. She could pardon Kevin and not a single person would think or feel any single way about it because frankly doing so would be treason. Someone going "well why can't I be pardoned then?" Just means straight to the gallows.
Also some lil nun thinking her actual queen and saintess might disappoint her is frankly absurd.
This is really starting to just feel like extension for extensions sake. The reality is that anyone in this position would have already mass produced all of the technology she's been having people work on yesterday. Dragon calamity? More like target practice.
