William suffers from a slight resentment, inherited from his father, that he actually has to work for a living. He sees himself as the equal of everyone and better than most.
He has no interest in becoming popular or part of a clique, he prefers total independence.
His most precious assets are his belief that he can persuade anyone to do whatever he wants and then his ability to succeed in doing this.
He watches everyone, continually accessing their strengths and weaknesses, storing the information away for a time when he can use it to good effect.
His father thought that being in Occitan with the Black Prince might give him the opportunity to marry the daughter of a southern lord but he has ambitions on a much higher plane.
