18. Tempus Fugitive

The legendary author H. G. Wells ( Terry Kiser ), arrives at the Daily Planet and wants to talk to Lois and Clark. When they hear he is from the future, they believe he is crazy and try to ignore him but Wells gets Clark's attention when he tells him that he knows he is Superman. Wells leads Lois and Clark to his time machine to meet Tempus ( Lane Davies ) only to discover that Tempus likes this new world instead of his ideal one, Utopia, and decides that he wants to travel back in time to when Superman first arrived on Earth, to kill him.

Tempus and Wells travel back in time but Wells changes the date to 1866 instead of 1966 to earn some time while at the same time he leaves behind the instructions of how to build the time machine. Superman builds the time machine and Lois and Clark get to 1966 where they realize that Tempus and Wells traveled to 1866 and they head there too. In 1866, Tempus reveals the truth about Superman's true identity to Lois, before he travels with Wells to 1966, and Lois is furious with Clark for not telling her. Eventually, they all arrive in 1966 where Lois and Clark manage to stop Tempus killing an infant Superman and they make sure the Kents will find the baby.

Wells takes Tempus in Dystopia and returns to take Lois and Clark back to present but a few moments before his first arrival so they will not remember anything, including Lois not remembering that Clark is Superman. Lois writes it down before they travel but Clark finds it and takes it away before Lois reads her own note.
