The character of John Locke (Terry O'Quinn) is featured in the episode's flashbacks, revealing how he broke up with his romantic partner Helen (Katey Sagal).
Meanwhile, Jack (Matthew Fox) plays a card game with Sawyer (Josh Holloway) before a large package of food is discovered to have mysteriously dropped on the island.
After checking the home of Nadia, he sees the same silver car near his house, and finds that it is his father driving it, who faked his own death to escape from the two men who are trying to kill him because of a "retirement con".
After collecting the money, Locke returns home and encounters the two men from the funeral who question him about the validity of his father's death and search his work bag.
Henry Gale tries to convince Locke and a suspicious Jack that he was making a bad joke about leading Sayid's (Naveen Andrews) group into a trap.
Seconds later, a female voice counts down from ten, and the blast doors begin to shut when she reaches zero, but Locke wedges one open with a crowbar.
It appears to be a multi-layered map of the island, but it is only shown briefly before the ordinary lights turn back on and the blast doors retract to their normal positions.
On the beach, Kate sees a flashing light in the jungle, and when she and Jack investigate, they find an enormous package of food attached to a parachute.
