There is friction aboard the Destiny as well as on Earth when a team of Earth-bound scientists think they've found a way to bring everyone on the Destiny back home. Col. Young isn't too keen on the procedure since it's not foolproof and even dangerous. With Young, Eli and Chloe visiting Earth, their replacements set about implementing the plan. Dr. Rush is dead set against it, but is he also putting a stick into the spokes to make sure the plan fails? On Earth, Young tries to reconcile with his estranged wife; Eli can't quite bring himself to tell his mother that it's actually him in someone else's body; and Chloe is hurt when she realizes her ex-boyfriend and best friend have hooked up.
