I don't know why they want to sell Kathryn in this way , she is just a hot girl for the show, any personality. For a love interest, the show must have deepen in her interests, opinions, skills, she is just there to kiss Liam and Robert. if Liam became King, she would be the queen? That girl without personality, show us the greatness that she has because there must be something for making two brothers to fight for her or inspiring a man as robert to be rescued.
