Crewman Jarvin was a Maquis fighter who served on the raider Val Jean under Chakotay until 2371. In that year, the Val Jean and the USS Voyager were both stranded in the Delta Quadrant by the Caretaker's array, and the Val Jean was destroyed when Chakotay rammed it into a Kazon warship while fighting the Kazon-Ogla. As a result, the crew of the Val Jean, Jarvin included, joined the crew of the Voyager as Starfleet personnel and traveled aboard Voyager during its historic trek home through the Delta Quadrant.
