In the year 2375, Ensign Jenkins was serving as the night shift flight controller under the command of Ensign Harry Kim when Voyager answered a distress call by a Druoda warhead, a sentient alien missile. The warhead took over The Doctor but the situation was resolved with the help of Ensign Kim. Jenkins thanked Kim on behalf of the junior officers, and in return he asked her for no more distress calls tonight. (VOY episode: "Warhead")
In an alternate timeline where the Voyager crew remained in the Delta Quadrant and formed a new coalition of worlds against the Borg and Species 8472, Ensign Jenkins became Voyager's new senior flight controller when the newly-minted Delta Coalition starship launched from the Kosnelye spaceport hub in November 2374 to defend the Vostigye Union against a Voth attack led by Sanctioner Haluk. Jenkins piloted Voyager close to Haluk's city ship to save Ambassador at Large Neelix.
In September 2375, Jenkins was at the helm when Voyager entered the extra-dimensional fluidic space in order to stop Kilana from collapsing that universe. (VOY - Myriad Universes novel: Places of Exile)
Ensign Jenkins was played by Mackenzie Westmore. Author Christopher L. Bennett named the ensign Tricia after Westmore's great-aunt Patricia Westmore, a hairstylist working for Star Trek: The Original Series.
