Lieutenant Nancy Randolph is a member of the science ship Ariel's crew in The Eye of the Beholder, kept as a zoo exhibit on Lactra VII and seriously ill when the Enterprise party arrives.
Nancy Randolph appears in the Animated Series episode The Eye of the Beholder. She is one of three survivors from the Ariel, a vessel that vanished while surveying Lactra VII, along with Lieutenant Commander Tom Markel and Randi Bryce.
The three have been collected by the Lactrans, enormous slug-like beings of great intelligence who regard humans as animals and keep them in a comfortable enclosure. Randolph has fallen ill there, and her companions can do nothing for her.
Kirk, Spock and McCoy are captured and put in the same habitat. McCoy needs his medical kit to treat her, so the humans concentrate their thoughts to coax a Lactran child into handing it over. Contact with the child at last shows the Lactrans that their specimens are thinking beings, and all are released.
