List of Star Trek: Voyager episodes

"Relativity" is the 118th episode of the American science fiction television series Star Trek: Voyager airing on the UPN network. It is the 24th episode of the fifth season.

Set in the 24th century, the series follows the adventures of the Federation starship Voyager during its journey home to Earth, having been stranded tens of thousands of light-years away. In this episode, Seven of Nine (Jeri Lynn Ryan) is recruited from the future to prevent the present-time destruction of her ship.

A 29th century Starfleet vessel, the timeship Relativity, is attempting to stop the detonation of an explosive planted on Voyager during its travel through the Delta Quadrant in the 24th century, which is causing a time paradox. Captain Braxton (Bruce McGill) and his crew are unable to detect where on Voyager the explosive is located, so they recruit Seven of Nine, pulling her out of the time stream moments before Voyager's destruction, as her enhanced Borg visual sensors can aid in the device's detection. Seven is sent back in time, disguised as a Starfleet ensign, to the point where Voyager is still in drydock prior to her maiden voyage and being inspected by Captain Kathryn Janeway (Kate Mulgrew). Janeway detects Seven's anomalous presence just as Seven locates the bomb. Relativity recalls Seven before she is discovered, but the travel through time kills her on return.

Knowing where the bomb is located, Relativity recalls a slightly earlier version of Seven, and after explaining the scenario, send her back again, now to a point where Voyager has been pulled into the Delta Quadrant and fighting the Kazon, prior to when Seven had joined its crew. Seven's presence is discovered by Voyager, and she is captured; Janeway recognizes her from drydock. Seven explains the situation to Janeway, and together they locate the device, discovering that it was planted by a future version of Braxton himself.
