Scorpion
Summary
Voyager is approaching Borg territory. The territory covers thousands of star systems and is too big to go around, but they find a narrow path through the sector that the Borg avoid likely due to the numerous gravimetric distortions within it. The senior staff agree that it is better to ride through this path, dubbed the "Northwest Passage", than to face the Borg directly. Captain Janeway orders preparations for a Borg encounter. While helping the Doctor craft antibodies to disable Borg assimilation, Kes has a brief vision of a pile of Borg corpses. She starts to experience several more, all based around the destruction of the Borg and Voyager.
