Joleg's brother Edit
After Neelix transmitted the letter, by the following day, Joleg inquired if his brother had responded. When Neelix stated that he had not, Joleg stated that his brother was "never good at corresponding."
Shortly thereafter, a Joleg's brother's ship attacked Voyager, attempting to free the prisoners held in Voyager's cargo bay. During the attack, Joleg took the Nygean warden Yediq hostage, but was stopped from killing him by Iko.
Neelix was outraged by his betrayal of their trust, but Joleg maintained he had no idea of his brother's intentions and that he might simply be sick, just like Iko, but Neelix refused to trust him anymore. (VOY: "Repentance")
Power plant supervisor Edit
This supervisor worked at the primary power plant on Quarra. She oversaw the section in which Kathryn Janeway, Jaffen, Tuvok, and Annika Hansen worked for a short time in 2377. She often ate at Umali's bar in her off time. (VOY: "Workforce")
These four prisoners were transported on a Nygean prison ship in 2377. When the ship had a cascade core breach they were beamed aboard the USS Voyager along with warden Yediq and two security officers. One of them was directly beamed into the sickbay together with the Nygean prisoner Iko.
When the Voyager crew learned that they were prisoners they were held in detention cells in a cargo bay from which they tried to break out after the force fields went down. Their breakout was unsuccessful and they were returned into their cells awaiting the death penalty. (VOY: "Repentance")
