No Win Scenario

With only a few hours of power remaining on the Titan, Riker admits Picard was right and suggests he spend his last moments bonding with Jack. In the holodeck, Picard and Jack tell each other some of their experiences. They are joined by Shaw who bitterly recounts his experience as a Starfleet engineer during the Battle of Wolf 359, when Picard had been assimilated by the Borg and was attacking the Federation as "Locutus of Borg". Vadic, who is a Changeling, is ordered to pursue the Titan at all costs. Doing so within the nebula requires disengagement of the portal technology. Jack, Riker, Beverly, and Picard form a risky plan to use an energy pulse from the nebula to recharge the Titan systems. Shaw and Seven help them succeed, and Seven identifies and kills the Changeling impostor.
