The seventh and final season of Star Trek: Voyager begins where the previous season ended, with Janeway facing a deadly encounter with the Borg Queen as she is headed towards assimilation in "Unimatrix Zero, Part II." B'Elanna faces many personal challenges this season. Her relationship with Tom is put in jeopardy when he decides to enter a race in "Imperfection." In "Lineage," she is strangely disturbed by her unborn child's Klingon traits. In "Prophecy," a group of Klingons separated from the rest of their race believes B'Elanna's unborn child is the Savior foretold in their sacred scrolls. The Doctor also faces some difficult dilemmas, including being torn between his duty to Voyager and his conscience when warrior holograms rebel against their Hirogen creators in "Flesh & Blood" Parts 1 and 2. Finally, in the series finale "Endgame," Voyager's quest to return home is aided by a visitor from the future: Admiral Kathryn Janeway. However, Janeway decides to risk Voyager's shortcut home in order to destroy the Borg and save millions of lives.
