She handles these people like such a pro. You want to make a mess, fine, clean it up yourself. Want me to bail you out? Better be willing to humble yourself enough to properly apologize. Even though she's not looking out for him, in a way she's actually helping the first prince. No one's properly disciplined him nor taught him responsibility for his actions, by forcing him to face the reality that he isn't always going to be the big shot in the room and making him concede, she may help give him the push he needs in the right direction. That of course depends on how teachable this kid still is, but no one else was going to teach him how to be a proper person.
