While on board Voyager Tomin was guided by Neelix, whom he surprised by insisting that he wanted to try different food and beverages in order to explore different cultures. Tomin indulged this desire so much that Neelix discovered him drunk the next day in Sandrine's. Later, at a reception in his honor, Tomin made a pass at Seven of Nine who nearly broke his arm in response.
Neelix was able to sober Tomin up, and with a large hangover he was able to greet the Kadi leader who asked him how he enjoyed Voyager. Tomin lied and stated that he had stayed within the guidelines of Kadi customs, only to be surprised when his leader told him he should have indulged himself, as long as he did not make a habit of it.
