Jack escapes Fayed's men and calls CTU from a stolen car, warning that the planned strike will kill the wrong man. Wayne Palmer refuses to cancel it, doubting Jack's judgment after his captivity. Jack drives to Assad's safe house himself. He persuades Assad to search his followers for the tracking device guiding the attack, exposing Omar as Fayed's informant. The three escape moments before missiles destroy the building.
At an abandoned house, Assad explains that he came to arrange a ceasefire and needs Fayed stopped before he can announce it. Jack starts questioning Omar but cannot continue hurting him. Assad takes over, extracts a meeting location and kills Omar, leaving Jack disturbed by his inability to work as he once did. In Washington, Sandra Palmer challenges an FBI demand for records from the Islamic-American Alliance. When the agents return with a warrant, she deletes the files and is arrested with Walid Al-Rezani.
Ahmed retrieves a hidden package from his house, kills the neighbor attacking him and takes Scott Wallace hostage. Jack and Assad follow Fayed's men to a subway station, splitting up so Assad can track the handler while Jack pursues the bomber. Aboard the train, Jack fights Nasir and kicks him through the rear window before the explosives detonate. The passengers survive, and Assad continues following their remaining lead to Fayed.
