Battlestar Galactica

About the series

Contains story spoilers.

Battlestar Galactica begins with civilisation reduced to a travelling remnant. The Cylons’ nuclear attacks leave fewer than fifty thousand human survivors, gathered in a fleet whose military protection rests on Galactica. Their search for somewhere to live is also an argument about what kind of society can survive aboard those ships. President Laura Roslin represents civilian government, while William Adama commands the battlestar; neither role removes the need to negotiate with the other. Humanoid Cylons make the enemy harder to identify than an attacking spacecraft. The reimagined series uses that uncertainty inside its most practical problems: who can be trusted with a ship, a weapon, an investigation or the next decision that might keep the population alive.

The first regular episode, “33,” puts exhaustion at the centre of survival. Every thirty-three minutes the Cylons return, forcing another jump and preventing meaningful rest. When the civilian liner Olympic Carrier fails to arrive with the fleet, the attacks stop. Its eventual return brings the pursuit back, and a radiation alarm reveals a nuclear weapon aboard. Adama wants the ship destroyed, but Roslin must weigh the threat against the uncertainty over its passengers. Lee Adama and Kara Thrace carry out the order after she agrees. The next jump finally breaks the cycle. The respite comes through a decision none of them can turn into a reassuring certainty about who was still alive on the liner.

“Water” makes the ship’s basic infrastructure a target. Sharon “Boomer” Valerii wakes disoriented and finds explosives among her belongings; discovering more detonators missing sends her to Chief Tyrol for help. During a water transfer, explosions tear open Galactica’s tanks, depriving the fleet of much of its reserve. Tyrol identifies sabotage but hides Boomer’s involvement, believing someone is framing her. Adama orders flights to find another source and privately acknowledges the possibility of a humanoid infiltrator aboard. Boomer locates water, yet struggles to report it while her sleeper personality tries to activate explosives in her seat. She finally brings back the discovery and is welcomed as a hero. The person helping solve the emergency is also entangled in the force that created it.

Getting that water turns into a political crisis in “Bastille Day.” The replacement supply is ice that requires a large mining workforce, and Lee proposes recruiting volunteers from the prison ship Astral Queen with a chance to earn freedom. Tom Zarek instead takes control of the ship and holds the delegation hostage, challenging Roslin’s unelected government. Lee recognises that a bloody military assault could give Zarek the scandal he wants. He negotiates control of the prison ship and a guarantee of elections in exchange for supplying the fleet with water, then protects Zarek from Starbuck’s shot. Roslin and Adama dislike the arrangement, but Lee points out that the prisoners still depend on fleet supplies and elections are already required by Colonial law.

The shortage of trained pilots has its own history in “Act of Contrition.” A loose communications drone kills thirteen pilots during a celebration and injures seven more, leaving Kara to train replacements without simulators. Her harsh decisions are connected to Zak Adama, William’s dead son and the man she loved. She had passed Zak through flight training despite his failure, allowing personal attachment to override her judgement. The new assignment forces that secret into the open when Lee challenges her handling of the recruits. William’s earlier reassurance that Zak’s death was not her fault becomes impossible to accept once she tells him what she did. He orders the trainees reinstated, and the practical need for pilots exposes a wound inside this surrogate family.

Kara’s disappearance immediately tests how far that family feeling can govern the fleet. After she is shot down, William and Lee keep expanding the search, eventually drawing combat patrols away from protection duties. On the moon, Kara finds a damaged Cylon Raider and discovers that it is partly biological, with organs and tubes inside. She uses its oxygen supply to stay alive and works out how to fly it. Roslin finally confronts the Adamas over the risk to everyone else, and William calls off the search. Kara returns in the enemy craft just before Galactica departs, identifying herself with tape on its underside. Lee escorts her home, and William’s visit to sickbay offers an indirect forgiveness for Zak without undoing the danger the search created.

Suspicion also changes the way the crew judges its own conduct. In “Litmus,” an Aaron Doral copy detonates a bomb aboard Galactica, and Sergeant Hadrian investigates how he reached the munitions store. Conflicting accounts of Tyrol’s movements are attempts to hide his forbidden meetings with Boomer. Socinus accepts blame for leaving a hatch open, but Hadrian continues pressing toward a wider conspiracy until Adama stops the inquiry. That does not free Socinus: Adama tells Tyrol that his secret relationship damaged his leadership and left him unable to account for his subordinate. Tyrol ends the relationship, while Roslin reveals the humanoid threat publicly. The investigation exposes genuine failings even as its methods turn increasingly indiscriminate.

Gaius Baltar’s case in “Six Degrees of Separation” makes evidence itself unstable. Shelly Godfrey, a visible copy of Number Six, produces an image supposedly showing him sabotaging Colonial defences. The accusation interrupts his Cylon-detector work and sends him into increasingly desperate attempts to avoid exposure. He tries to destroy the photograph, is arrested, and even Roslin treats her suspicion as sufficient reason to condemn him. Gaeta’s examination eventually establishes that the image is forged, and Baltar is freed and publicly cleared. Godfrey vanishes, leaving only her glasses behind. The Six who appears privately to Baltar then presents the ordeal as something that has strengthened his position. Being exonerated has not clarified whom he can trust, or what the people guiding him actually want.
