While aboard the transport, he enjoyed telling Trip Tucker his stories, ranging from Fluvian fungus, to the tastes of Melvaran mud fleas and Cardassian tojal, to his encounter with an Orion slave girl. Zoumas also had a knowledge of the other aliens on the Transport. He helped break up a fight between Trip and a Nausicaan prisoner and he warned Archer about Kuroda Lor-ehn. (ENT: "Canamar")
In the final draft script of "Canamar", Zoumas was described as "a thin, nervous alien." During a scene in which Jonathan Archer is informed he is about to be released, Zoumas was scripted to be sleeping "fitfully". However, he is clearly awake in the final version of that scene. Similarly, a line of dialogue that wasn't in the episode's final draft script features Zoumas, speaking to Tucker, react to a Nausicaan prisoner who sarcastically apologized to Tucker, Zoumas stating, "That was nice. It reminds me of the time I was on..." before Tucker shuts him up, which was also not in the final draft teleplay.
