Trivia--In the original draft, the character whose parents had been murdered by Kodos was named "Lt. Robert Daiken". When Bruce Hyde was cast in the role, the staff realized that he played the character Kevin Riley in "Star Trek" (1966) The Naked Time (#1.4) so the character was rewritten as Riley.
