I see Napoleon finding a beautiful woman and drowning his sorrows in a night of food, wine, and sex. While he projects a laissez-faire attitude, I see him as needing distance and distraction between the event and his mental resolution.
I see Illya retreating to his roots and dealing with things in a different manner. And as he is the more physical of the two, I could see him re-routing his anger through the gym, the firing range or something along those lines.
What say you, cousins?
