During his interrogation of anti-Taelon activist Nell Hagar (T.L. Forsberg), Agent Ron Sandoval (Von Flores) collapsed in intense pain with blood running from his ear. William Boone (Kevin Kilner) transported him to Dr. Belman (Majel Barrett Roddenberry) who confirmed that Sandoval's CVI was breaking down, endangering his life. Da'an (Leni Parker) gave permission for the degenerating CVI to be removed because he knew it must be replaced for Sandoval to survive. Boone worried he was facing the same fate, but was soon caught up in a violent confrontation with Sandoval, who threatened Da'an and took Captain Lili Marquette (Lisa Howard) hostage as he escaped on the shuttle. Sandoval's mind may have been freed from Taelon control, but he faced certain death without a new CVI.

Boone raced to save his fellow security agent because the Taelon Synod ordered Sandoval's "termination." The Synod knew that unlike Boone's, Sandoval's implant had given him the full picture of the Taelon presence on Earth and their plans for the future.

Sandoval ordered Lili to take him to the hospital where he had institutionalized his wife Dee Dee (Shary-Lee Guthrie) in one of his first heartless duties as a Taelon Implant. He tied Lili up in the shuttle and found Dee Dee, determined to get her to a safe place. Boone tracked Sandoval to the hospital and arrived with a SWAT team, releasing Lili from the shuttle. They confronted Sandoval as he wheeled his drugged wife out of the building and a shoot-out ensued. But Boone let Sandoval escape, even though he may only have had hours to live.

Sandoval reconciled with Dee Dee and helped her recover from the drugs in a hotel room. He then used his global to access information that would help him find Jonathan Doors (David Hemblen) and hopefully, asylum with the Resistance. Boone followed Sandoval to Nell Hagar's loft, where he told Sandoval he was part of the Resistance and offered to help. He took Sandoval and Dee Dee to a safe house, where Sandoval again collapsed. Dr. Belman confirmed that in order to save him, she had to turn Sandoval back into a full Implant with another fully-functional CVI, which would obliterate any trace of the person he was.

Dee Dee was dead, and Sandoval believed Boone had murdered her, just as he murdered Boone's wife under Taelon orders. Believing himself to be alone in the world, Sandoval underwent the operation, returning to serve Da'an and the Taelons.

In reality, Dee Dee was given a new identity by the Resistance. And Sandoval was changed, even as an Implant. He thanked Boone for saving his life, and although he no longer had full access to the truth behind the Taelon presence on Earth, he did reveal that the fate of humanity and the Taelons are inextricably linked. That they need humanity as much as humanity needs them.

Sandoval assumed Boone had only pretended to be part of the Resistance to get him back under control and still believed Boone was a full Implant like himself. But when Boone saw Sandoval wearing Dee Dee's wedding band -- a decidedly sentimental gesture for an Implant -- Boone wondered whether Sandoval might be leading his own double life.
