- Sandoval's CVI broke down and was replaced by Dr. Belman.
- Sandoval believes that Boone killed his wife Dee-Dee for the same reasons that Sandoval killed Boone's wofe in "Truth."
- Before re-implantation, Sandovals yells "Damn you, Boone!" Afterward he begins wearing his wife's wedding ring on his little finger.
- Sandoval freed Dee-Dee from the sanitarium, and the Liberation provided safe passage to a new life where she would be safe from the re-implanted Sandoval and the Taelons.
Ronald Sandoval
- Sandoval was an "eager supplicant" when the Taelons recruited him. Both he and his wife Dee-Dee believed in the Taelons. However, Dee-Dee was angry that her husband devoted himself so much to them.
- After implantation, Sandoval saw Dee-Dee as a rival to the Taelons and had her committed and medicated at The Vandewater Institute in Restin, Virginia, where he subsequently placed other "clients" (see "Truth").
- Beneath his CVI motivated personality, Sandoval regrets his ordering of Kate Boone's murder (see "Truth"). He also hates the Taelons for taking away his humanity.
Julianne Belman
- Dr. Belman has been working, unsuccessfully, to determine why the CVIs wear out and how to fix the problem.
The Taelons
- Agenda on Earth
- The Taelons apparently face a time constraint on Earth and wish their Implants to feel a "sense of urgency" about their service to the Companions.
- After his reimplantation Sandoval tells Boone, "They need us as desperately as we need them. The fates of our two races are intertwined. Without them, we're doomed; without us, they're doomed. To destroy the Companions is to destroy ourselves."
- Technology
- CVI: Further symptoms of a CVI breakdown include headaches, bleeding ears and seizures (see "Avatar" and "Live Free or Die"). Dr. Belman has developed an anti-cyber virus that seeks out and kills a CVI without harming its host. She still has made no progress in determining why the CVI breaks down, and she informs Boone that the brain cannot survive without a CVI after it has adapted to one's presence. The earliest generation of CVIs contained a supplement of information about the Taelons and their mission on Earth.
- Shuttle: The vehicle is equipped with a transponder and a radar jamming device.
