When Jarod and Angelo arrive at the airstrip and Jarod jumps the fence, he is wearing white sneakers. When he begins to run, he is seen wearing black dress shoes.
While Jarod is in the basement of NuGenesis, he watches a tape of himself solving the infamous "block problem". The blocks read r/(931)sqrtpi9. When Young Jarod reads it, however, he says "Pi times the square root of 931 divided by the radius of the circle," which, of course, doesn't make sense based on how he's looking at the blocks.
