Seska also expressed her disappointment in Chakotay, whom she believed naively followed Janeway, and stated that she couldn't imagine why she had ever loved him. When Chakotay confronted her, revealing the cover-up, she finally confessed to everything and openly expressed her dislike for Captain Janeway's decision, calling her a fool for having gotten Voyager stranded in the Delta Quadrant, Janeway being unwilling to give the Kazon what they wanted so that Voyager could have a powerful ally in the Delta Quadrant. Seska denied this, claiming that she had suffered from Orkett's disease as a child and received a bone marrow transplant from a Cardassian woman named Kattell to survive. The Doctor's subsequent examination revealed her to actually be a Cardassian altered to look Bajoran. Her true origins remained undiscovered until the time she helped transfer replicator technology to the Nistrim and was seriously injured during an attempt to cover-up her involvement in the transfer. She did not believe it mattered if something simple like replicator technology might shift the balance of power in this part of the quadrant, and she believed the primary goal should be to get back home and that was all that mattered.

Her disdain of Starfleet and Starfleet principles, such as the Prime Directive, led to her distancing herself from the crew further, ultimately leading to collaboration with the Kazon-Nistrim, offering them replicator technology in exchange for their help in this unknown part of the galaxy.

When their plan to steal the technology failed, she attempted a cover-up, but Torres held her back, stating that she did not want to lie anymore вЂ“ something Seska found rather disappointing. She was involved with Lieutenants Torres, Joe Carey, and Tuvok in a covert attempts to acquire spatial trajector technology from the Sikarians, behind Captain Janeway's back. ( VOY: ' Caretaker', ' Parallax', ' Prime Factors') Not very fond of the Federation, Starfleet, and their 'mighty principles', she often expressed her disapproval and annoyance with their rules and made it clear to Chakotay that if the situation ever necessitated it, she would support a Maquis mutiny. ( VOY: ' Caretaker') She was close friends with B'Elanna Torres and on Voyager was granted the field commission of Ensign, initially in the science department but later moving to engineering. She served under Chakotay aboard the Maquis raider Val Jean when it was catapulted into the Delta Quadrant by the Caretaker's array in 2371. Seska first joined the Maquis in 2370 while undercover for the Cardassian Union.
