Arthur really tried to figure out what she was talking about, but he did not know how not to be proud of being the prince of Camelot. His father and everyone else were always telling him how fortunate he was, and how his duty was to try to be as good a king as Uther. Maybe if he thought it over later, he would know what she meant.
"Gwen, if we get back to Camelot, will you visit me?" She was nice, and pretty, and explained things to him. Mostly.
