While giving viewers insight into the not-so-exiting former life of the mysterious Locke (Terry O'Quinn), flashbacks in this episode also reveal one shocking secret about the circumstances of that life. Elsewhere, the island continues to be a source of wonder and bafflement as the survivors are "introduced" to its daunting variety of wildlife. And while trying to deal with the corpses of those who didn't make it, Jack (Matthew Fox) sees -- or thinks he sees -- someone who wasn't on the flight.
