Comments:
Part 2: "The Wedding of Lara and Luthor"

Though no mention is made in this story, Luthor's time-space warp must take him to the Krypton of a parallel universe as established events are contradicted. Jor-El and Lara are married prior to the theft of Kandor, but not in this story. Nor should the Phantom Zone have been discovered at this point. Also Superman was present during Kandor's abduction. Therefore this must be a parallel Krypton and not the true Earth-One version.

Synopsis:
Luthor invents a time-space warp which allows him to travel back to Krypton before it exploded. On Krypton he pretends to be a hero and prophet. He proposes marriage to Lara before she marries Jor-El. However, before their marriage can take place his deception is found out. He flees Krypton, returning to his own time and place, without changing history including the origin of his nemesis Superman.
