That year, during the Voyager's shakedown cruise, a system malfunction necessitated the assistance of the USS Hood. The Hood's first officer, Dina Voyskunsky, was a woman with whom Cavit had a romantic relationship with early in his career, before an acrimonious breakup in 2359. The two agreed to a get-together shortly after the end of their cooperative mission. (VOY - The Brave and the Bold, Book Two novella: The Third Artifact)
During the mission to locate a missing Maquis starship in the Badlands, Cavit showed a great deal of contempt for Tom Paris. Believing the man to be a disgrace to the Starfleet uniform, Cavit made his dislike of Paris so obvious that Janeway made a mental note to talk to him later about the need to behave professionally even with Paris.
In an alternate timeline in which the Cardassian Union did not withdraw from Bajor in 2369, Cavit was the first officer of a version of Voyager which was not stranded in the Delta Quadrant by the Caretaker in 2371. He and Captain Janeway typically had a drink in the mess hall after their duty shifts ended. Janeway reflected that she could not imagine running the ship without him.
He was killed in 2373 when Voyager was destroyed in the Dorvan sector by a fleet of Cardassian Galor-class warships armed with phased polaron beam weapons, which they had procured from their newfound Gamma Quadrant allies, the Dominion. (TNG - Myriad Universes novel: A Gutted World)
