The Destiny crewmembers left behind on an idyllic planet over a year ago suddenly turn up aboard a shuttle, giving Tamara (ALAINA HUFFMAN) renewed hope of finding her lost daughter. The circumstances surrounding their surprising return remain a mystery however. Dr. Caine (TYGH RUNYAN) and the others have no memory of how they got there. Young (LOUIS FERREIRA), fearing alien involvement, isolates Caine and co. Tamara’s examination of the former crew verifies not only their identity but also that they are all in perfect physical condition. The investigation of the shuttle reveals the same: it is like new. The mystery takes an unsettling turn when one of the returned crewmembers abruptly drops dead. Wray (MING-NA) lobbies Young to let her use regression therapy in the hopes of learning what really happened back on the planet. Young agrees, but the memories stirred prove disastrous for those who’ve returned. Meanwhile, as her alien transformation progresses, Chloe (ELYSE LEVESQUE) prepares her final goodbyes.
