Berserk Button: She flips out any time she thinks Mario is cheating on her. And she loses it when she thinks Mario is dishonest on her. After the prostitute tells Mario she's likely to contact his "pee-pee" for five bucks, an indignant Rosalina thinks he is dishonest on her and beats Mario up. The prostitute exhibits up a handful of seconds later on and tells Mario they talked on the mobile phone, complicated Mario and Rosalina.
