Lian was working for the Chinese MSS, and Gabe saved her from an ambush. When it's Lian's turn to testify, she mentions her first meeting with Gabe during the Soviet occupation of Afghanistan. Mujari retrieved samples and gave them to Teresa. At the Pugari Gold Mine, he discovered that mining slaves had caught a deadly plague and the mine owners were covering it up. Mujari testifies next, and tells Hadden how he once worked for a resistance during the Apartheid era in South Africa. Gabe did not know back then that Benton and the Agency controlled Rhoemer, who escaped from the plane. Gabe chases Rhoemer onto an airplane despite his Agency superior Edward Benton warning against it. When they arrive, the two see that Erich Rhoemer has ordered Ellis killed, but Gabe must continue his mission and identify what Rhoemer was doing at the drug plantation. He and Lian went to Costa Rica to find missing Agent Ellis. Gabe begins by describing the first Syphon Filter investigation. The three do not realize that Hadden is involved in the conspiracy, and is looking for scapegoats.

He considers all three to be guilty, and questions them after they assassinate Shi-Hao from a hotel in Japan. Secretary of State Vince Hadden brings in Gabe, Lian, and Mujari to testify in Congress about their relationship to the Agency.
