Trivia: When the cloud creature threatened the populated planet of Mantilles, Kirk ordered that the ship's self destruct system be armed, and he was prepared to blow up the ship to destroy the cloud's "brain." The self detruct system was used in several original series episodes.

  • We learned that Commodore Wesley retired from Starfleet to become the governor of Mantilles, a planet with a population of 82 million. We also learned that he had an eleven-year-old daughter. Commodore Robert Wesley was first seen in the original series episode "The Ultimate Computer" and was portrayed by Barry Russo.
