When Louis tells Mr. Lopez he doesn't understand the algebra lesson, the equation written on the chalkboard behind the teacher changes from one shot to the next.
Louis is suspended for a week beginning on the day before the track meet, but the next day he shows up at school, in his algebra class, and at the track meet. Shouldn't he still be at home?
Principal Wexler says that Louis has been suspended, but it's only for a week. So why would they be cleaning out his locker?
