Locke arrives at Boone's funeral and is attacked by Jack. Locke asks for Shannon's forgiveness, to no avail; instead, Shannon steals the key to the gun case from a sleeping Jack, and confronts Locke in the jungle. Sayid tackles Shannon just as she fires the gun and the bullet grazes Locke's head. Sayid later tells Locke to take him to the hatch. In flashbacks, Sayid becomes an informant for the Australian Secret Intelligence Service and the CIA, which has asked him to infiltrate a terrorist cell of which his old friend Essam is a member. Sayid agrees to do it in return for Nadia's whereabouts and he betrays Essam, who kills himself.
