 Three years ago, when Ensign Lyndsey Ballard died on an away mission, Voyager gave her a traditional burial in space. Her remains were recovered by the Kobali, a race that procreates by reanimating the corpses of other races and altering their DNA. When Lyndsey flees the Kobali and returns to Voyager, Janeway is skeptical but medical scans prove she is the real deal. While The Doctor can t make her human again, he alters her appearance to look like her old self and she tries to reintegrate herself with the crew. Also in this episode, Seven of Nine is frustrated to find the Borg children act more like children and less like Borg, despite her allotting  fun  in their daily schedule.
