I think I misread one thing before and boy, am I happy I did. Due to the hairstyle, I thought Jean-Baptiste was boning his MOM. That is MUCH better. Still a traumatic thing, but imagine your pops boning your grandma to make a better you before your very eyes! Yeah, him boning his wife is much better.
When will this misery stop? What will be the turning point for Charles? He goes on to become a legend (gruesome, but still), so something has to shift his psyche.
