The Venturer's crew are amazed to find Nova in possesion of the dog tags of a Colonel Ronald Brent when they meet her. Later in the series the mystery is solved when they find the wreck of Brent's ship and find Brent himself still living inside, having met and then lost Nova's tribe many years earlier. Brent left Earth 150 years after the Venturer but arrived on the ape planet about 15 to 20 years earlier than them.
- The character of Ron Brent was created by writer Larry Spiegel.
- The character of Ron Brent is an analog to John Brent from Beneath the Planet of the Apes, in that he is an astronaut who travelled to the future and his ship was destroyed in a crash-landing.
- Oddly, Brent's dogtags gave his first name as Roland, not Ronald.
- Brent shares the same birthday as the show's director, Doug Wildey.
