Corrected entry: When John first tries his newly acquired powers out, he is on a cliff and looks down to the rock he's going to back-flip onto. However, in the overhead shot while he is in the air the rock is not visible in the water until he lands on it.

Correction: His body obscures it when he jumps. It's also hard to see it because the water (and the rock) is in the shade BUT it is there.
