Sydney and Vaughn track Cypher, a Covenant cyber terrorist targeting worldwide medical facilities, to a Berlin club, but Lauren, disguised as a club waitress, shoots him. Before Cypher dies, he gives Vaughn the computer worm, which is designed to search genetic databases to find a specific woman, whom Dr. Robert Viadro has treated. Sloane reveals his recruitment by Sen. Reed into The Trust, a secret U.S. Government organization, to which Sloane's been tasked to provide Rambaldi information in exchange for his pardon; Diego Machuca verifies Sloane's recruitment, adding "Project Centigrade" is their black budget front. To ensure Sloane's death penalty, Jack denies the Trust's existence. Lauren tortures Dr. Viadro for the woman's identity. Losing faith in Lauren's effectiveness, Bomani Kazari plans to shoot her, but Sark kills Kazari, saving Lauren. Suspicious of Lauren, Vaughn checks her belongings, finding her gun, silencer and the wig she wore to disguise herself as the club waitresses, which unveils her as Cypher's murderer.
