Superman listens to a taped diary of Jor-El’s found on the Moon years ago. In it, he hears his father speak of his early childhood, how he became a scientist and discovered a system of anti-gravity propulsion, how he met Lara Lor-Van, how he invented the Phantom Zone ray, and how he and Lara were married--an event Superman remembers, since he attended it.
