Admiral Janeway takes her shuttlecraft and enters the transwarp hub, finally arriving at the Unicomplexâthe center of all Borg activity, where the Borg Queen herself resides. She first appears to the Queen in her mind, claiming she wants Voyager towed back to the Alpha Quadrant (apparently in defiance of the younger Janeway's plans) in exchange for information on how to adapt to the armour and torpedo technologies. However, the Queen is quickly able to detect her shuttle and beams the Admiral to her chambers for assimilation into the Borg collective. A few minutes later, Admiral Janeway unleashes a neurolytic pathogen from within her bloodstream that devastates the Borg, physically making the queen fall apart. With the deactivation of the Queen, the Unicomplex suffers a cascade failure and explodes, killing the partially assimilated Admiral.
Meanwhile Captain Janeway and her crew have entered a transwarp corridor and fire torpedoes at the unprotected manifolds while traveling back to the Alpha quadrant, but are pursued by a Borg sphere ship that has managed to withstand the pathogenâs effects and assimilate Admiral Janeway's ablative armor upgrade. It is now following the Borg Queen's final orders to destroy Voyager so that the Admiral (and her sabotage) will never exist. Unable to fight back against the shipâs exterior defenses, Janeway takes her ship inside the sphere, where, upon its arrival in Earth's solar system, she detonates a torpedo that destroys the sphere from the inside out.
In the showâs final few minutes, the crew stand dumbfounded that they have finally returned home after seven years lost in the Delta Quadrant and are greeted by a fleet of Starfleet vessels that arrived to fight the sphere. Settling down in her chair, Captain Janeway issues her final words; the same words that she used at the start of her journey: "Set a course...for home."
