Uh I think you misunderstanding something here, I mean the dryad. Not the female knight .
If she is his wife also, looks like I missed when it happened :unsure:
I'd like to imagine what happening now is somewhat a daily occurrence during their childhood.
There is always some kind of misunderstanding and it somehow resulted in something good every time and then they would interpret it as Cry's doing it intentionally so it made sense they value him so highly.
