<P> Admiral Janeway takes her shuttlecraft and enters the transwarp hub, finally arriving at the Unicomplex--the center of all Borg activity and the home of the Borg Queen . Janeway appears in the Queen's mind, claiming she wants Voyager towed back to the Alpha Quadrant (apparently in defiance of the younger Janeway's plans) in exchange for Voyager's armor and torpedo technologies . However, the Queen detects 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 her bloodstream that devastates the Borg and causes the queen's cyborg components to fall apart . With the deactivation of the Queen, the Unicomplex suffers a cascade failure and explodes, killing the partially assimilated Admiral . </P> <P> Meanwhile, Captain Janeway and her crew have entered a transwarp corridor and fired torpedoes at the unprotected manifolds while traveling back to the Alpha Quadrant . They are pursued by a Borg sphere that has managed to withstand the pathogen's effects and assimilate Admiral Janeway's adaptive armor upgrades . The sphere is under orders from the Borg Queen to destroy Voyager so that the Admiral (and her sabotage) will not have occurred . Unable to fight back against the sphere's defenses, Janeway takes her ship inside the sphere, where, upon its arrival one light year away from Earth's solar system, she detonates a torpedo that destroys the sphere from the inside . </P> <P> In the show's final minutes, the crew stand dumbfounded that they have finally returned home after seven years in the Delta Quadrant and are greeted by a fleet of Starfleet vessels that had arrived to fight the Borg . Settling down in her chair, Captain Janeway issues her final orders with the same words she used at the start of Voyager's journey from the Delta Quadrant: "Set a course...for home ." </P> <P> In the Star Trek franchise, a classic story plot - line is that characters from the future alter the past to change the future, as seen in Star Trek IV: The Voyage Home or "Yesterday's Enterprise". Within the Voyager series, an episode like "Timeless" also follows this narrative . This can create significant screen time of events that are destroyed as the past is altered . A review of some of the contents of a partially explored timeline before it is reduced to a seven - year journey by Admiral Janeway: </P>
