I don't know I sure got a "but I don't wanna be king" vibe from him, while in the book he knew what he wanted and went and took it. Could just be me however.
How is not wanting to be king "whiny?" Did he ever say "I DON'T WANT TO, DAD!"
Even Bruce Campbell didn't want to save people from legions of the undead, but that doesn't make him a whiner.
