There is no food and Lock goes with Michael and Kate to the jungle to hunt boars. John has a case full of knives and the passangers are already afraid of him. While out there in the jungle they are attacked by "the monster" and Locke looks into the eye of the island. Jack starts having an illusions while Claire holds a memorial service for the dead and they are burned inside the fuselage. FLASHBACK LOCK:
We see that Lock was constantly mocked by his boss Randy and that he took all of the games to serious. He also has a love of his life but it turns out that she is his psychiatrist. Lock goes to Sydney so he can attend Aboriginal walkabout but he is rejected because of his "condition" and that is when we find out that he was in a wheel chair and when he crashed on the island he was heald and he can now walk again.
Absolute classic of the show!
