The appearance of the Trill symbiont would change its appearance from when it initially appeared on this episode to how it would appear on Star Trek: Deep Space Nine
(1993). In this episode, the symbiont's appearance was made to resemble a caterpillar with the head of an octopus. According to Make-Up Supervisor Michael Westmore
, the symbiont was re-made for DS9 to be more "stream-lined" to make it easier to handle. Also the appearance of the Trill hosts would change as well. In this episode, the Trill hosts had semi-ridged foreheads and no body spots , but on DS9, they have normal foreheads, and body spots. See more
