You know, if I had the choice. I would've erased the Duke's son to begin with. No matter where you look. You cannot and I repeat cannot find a good solution to reforming his character. The only way you could is having that brat pared with a women that doesn't give a fuck. And even if you find a way to decrease his playboy ways. He is going to be a terrible leader and I repeat a terrible leader for his household. And I bet that he is going to drag his household into poverty for just associating with evil people. Srsly I feel bad for the brat's dad. From the little info we have so far. He seems like a average person.
