- Ass Pull: McCoy's disease is an insoluble problem for most of the show, until Spock discovers that the Fabrini have extensive medical knowledge in their archives including, rather handily, a cure for the incurable (and one that works on humans, no less). At that point it takes about one minute of screen time to fix the good Doctor.
- Narm: The good people of Yonada worshipping a doorbell.
- One-Scene Wonder: John Lormer's Old Man, whose sole scene consists of a kindly, sweet attendance on the main trio, an attempt to help give them information that gets him killed for his troubles, and the episode Title Drop. Short, but surpisingly moving.
- Theiss Titillation Theory: Natira wears a backless cut-out toga made of a green-gold satiny material. This contrasts with the psychedelic muumuus the other Fabrini wear. Whatever takes our attention away from those Highlanders meets Hell's Angels outfits the soldiers wear!
- They Wasted a Perfectly Good Plot: McCoy's illness. Just imagine what a modern day show could do with a character having a fatal disease and racing against time to find a cure, rather than knowing it'll be fixed somehow by the end of the episode.
