The FBI team is invited to the palace of Saudi Prince Ahmed bin Khaled for a dinner. While at the palace, Fleury persuades the Prince that Colonel al-Ghazi is a natural detective and should be allowed to lead the investigation. With this change in leadership, the Americans are allowed hands-on access to the crime scene. While searching for evidence, Sergeant Haytham and Sykes discover the second bomb was detonated in an ambulance. Fleury learns the brother of one of the dead terrorists had access to ambulances and police uniforms. Colonel al-Ghazi orders a special forces team to raid a house, managing to kill a few heavily armed terrorists. Following the raid, the team discovers clues, including photos of the U.S. and other Western embassies in Riyadh. Soon afterward, the U.S. Embassy Deputy Chief of Mission Damon Schmidt notifies Fleury and his team that they have been ordered to return to the United States.
