After hearing that the people recorded on previous experiments are dead, one of the tourists guesses correctly they will die, too. The meeting ends abruptly as Morel leaves in anger. The fugitive picks up Morel's cue cards and learns the machine keeps running because the wind and tide feed it with an endless supply of kinetic energy. He understands that the phenomena of the two suns and two moons are a consequence of what happens when the recording overlaps reality — one is the real sun and the other one represents the sun's position at recording time. The other strange things that happen on the island have a similar explanation.
