A team from Galactica boards the infected baseship and finds hundreds of dead and dying Cylons. It's an intelligence windfall. Adama (Edward James Olmos) orders the team to tap into the dying Hybrid and to return with the surviving Cylons. Adama sends Starbuck (Katee Sackhoff) in to interrogate them. The deal she offers the Cylons is simple: cooperate and you get the vaccine and live; resist and you die - forever. Simon (Rick Worthy) reveals that Baltar (James Callis) is helping the Cylons find earth and Lee (Jamie Bamber) gets an idea: if the virus is spread by resurrection, it may be possible to set a trap and use it to destroy the Cylon race. Helo (Tahmoh Penikett) is outraged - this is genocide, the extinction of his wife's race - but Adama and Laura (Mary McDonnell) take the idea seriously. Meanwhile, the Cylons hold Baltar responsible for the virus and are torturing him for more information. Number Six (Tricia Helfer) talks him through the pain, filling his mind first with pleasure and then with a warning. As Galactica's trap is sprung and the Cylons move in, Baltar must once again choose between his own people and his captors while Helo must decide how far his loyalties will go.
