Sayid flies to Sydney and infiltrates the terrorist cell, telling the agents that Essam is in over his head, and that he can bring him in. The agents tell him to convince Essam to go ahead with the suicide bombing so that he will lead them to the explosives, and threaten Nadia's life when Sayid attempts to refuse. On the day of the attack, Sayid reveals he is an informant, and a distraught Essam kills himself.
