Prince brat

Much of his behavior is actually an attempt to get his father's attention as he feels that he is too busy with being the King to notice his very lonely child. Much of it is fueled by spite and a general lack of boundaries or demands on him to treat others nicely. Although at first he does not seem smart enough to follow Jemmy's escape plan he soon realizes that he can learn a lot from his whipping boy and starts to emulate him more. Prince Brat is very lonely and does not have any friends his own age at the palace, so he really envies Jemmy his friends and their obvious liking for him. At the end of the book his character has really transformed and he becomes a much nicer person because of his adventure.
