He's not as bad as his brother, not really, but in some ways he's worse. He's very smart, good at magic, and good at physical stuff -- but he's manipulative and never tries beyond keeping himself from falling behind in the special classes. Except, when he realizes it bothers her, he decides to ace all his classes, combat exam, and magic exam just to out-do her -- except that this causes her to go hell for leather for studying / practicing / learning magic to try and show him up, which might have been his intention in the first place. IIRC he gives off the impression that he feels that anyone not a member of the royal family is a subhuman.
