He's very studious and a complete perfectionist. He tends to hole himself up and study for hours on end until he is absolutely sure that he knows everything he needs to know and will ace his classes.
He keeps to himself and often admits that he only has friends because his twin sister, Evelyn, stubbornly forces him to get out of the house and hang out with her friends.
He can be a bit spiteful of others who have things come naturally to them, because he has had to work very hard to get as far as he has.
