Plot summary
Before his paralysis, Locke is approached by his long-lost father, Anthony Cooper. An ailing Cooper subtly guilts Locke into giving up his kidney, only to learn after the surgery that it was a con to keep Cooper alive. In the present, Locke has a nightmare about a Beechcraft crashing in the jungle and losing the use of his legs, the latter of which starts to happen as he takes Boone to find the Beechcraft. They discover the dead body of an armed Nigerian priest, leading them to the Beechcraft. With Locke unable to climb, Boone goes alone and finds Virgin Mary statues with heroin inside.
He sends a distress call out on the radio, only for the man on the other end to also identify himself as a survivor of Flight 815 crash before the Beechcraft falls, severely wounding Boone. Locke dumps him at the camp before fleeing to the hatch, where he pounds on it in frustration until a light turns on.
