So, Ian studies accelerated math, using his magic to be sure his problems are right, so he can win the contest. So when the math contest arrives Ian wants to win badly, but he has discovered Thomas' mother is sick and Ian feels badly for him. He realizes Thomas is a real person, not just a math genius. And there is always next year.
