Lost Episode 2.03 Orientation

We back up in time once again to see the journey into the hatch from Kate's perspective, where she escapes the pantry that she's been locked into and overpowers Desmond using a gun found in the hatch's armory - damaging the computer in the process.

Jack demands answers. Desmond explains that he was in a solo sailing race around the world when his boat ran aground on the reef. A man named Kelvin brought him to the hatch and instructed him to enter a series of numbers into the computer every 108 minutes in order to "save the world."

Locke is intrigued; Jack is skeptical. Desmond tells him to watch a film called Orientation for answers. The film details the DHARMA Initiative, a countercultural research project begun in the 1970s. It also provides key instructions for the operation of the computer in Station Three, i.e., the hatch, and hints at an unfortunate "incident" that made necessary the institution of this protocol. But it does little to convince Jack, who thinks it's all a mind game - a psychological experiment. Desmond remains committed, however, and makes every attempt to repair the computer.

Meanwhile, Michael, Sawyer and Jin are tossed into a trap in the ground by the imposing strangers they encountered on the beach, and must try to figure out how to escape. A woman, whom we recognize from the airport, is thrown in with them, only to turn against her fellow survivors.

Unable to fix the computer, Desmond flees, leaving Jack and Locke at odds over what to do. Kate fetches Sayid, who manages to fix the computer in the nick of time. Now Locke must convince Jack to take a leap of faith and assume Desmond's job, just as in the flashbacks, where Locke's new girlfriend, Helen, convinces Locke to take a leap of faith and let go of his anger towards his father.
