As Locke and Sawyer trek through the jungle, Locke proceeds to reel off certain points of Sawyer's life, provoking Sawyer to attack him and threaten him with a knife. Locke admits that he cannot bring himself to kill Ben, whereas Sawyer reveals that he killed the wrong person by mistake and he didn't mean to kill the man he killed. Locke leads Sawyer to the "Black Rock", the derelict slave ship seen in a previous episode, taking him inside to the brig where a man sits chained, gagged and hooded. Locke locks Sawyer in the brig with the prisoner, ignoring Sawyer's enraged pleas to unlock the door. Danielle Rousseau (Mira Furlan) enters the Black Rock and is surprised to see Locke. She explains she is looking for dynamite. Locke does not give an explanation for his presence or for Sawyer's banging on the door, but he does point her to the dynamite; she takes a crate and leaves. In the brig, Sawyer threatens to shoot Locke through the door if he won't open it, but Locke tells him that if his gun had bullets he would have threatened him with it, and not a knife, in the jungle.
