VOY unlike most ships, couldn't receive replacement crew e very other episodes. As such it had a chance to build up a decent secondary cast. Who we would see fairly often. Apart from Carey and Vorrik VOY failed to utilise a small number of secondary characters. Anyone remember the Transoprter Chief from TOS who was more often or not Lt. Kyle. Who was Voyager's Transporter Chief?, almost seemed to be a new one every week.
