Plot summary
The Destiny docks with an ancient Stargate-seeding ship. Rush, Eli, and the scientists try to link the ships' power together to dial Earth, while Scott and Greer explore the ship. The group encounters an alien and tries to befriend it. When Col. Young decides to capture the alien, the alien escapes and the other aliens that were with it decide to reverse the energy transfer, interrupting the dialing and threatening to leave Destiny power-drained and adrift. Eventually Rush manages to unlink the two ships in time, but Telford is left behind.
