Event Year: 2004

Adama stages a boxing tournament on the Galactica to help the crew relax. The competitive atmosphere sets off a brutal match between Kara and Lee. Flashbacks from New Caprica reveal the origin and nature of their dispute.

A figure from Adama's past returns to haunt him. His return raises questions about why the Cylons launched their initial attack against the Twelve Colonies.

Lingering feelings of rage lead Saul Tigh and Kara Thrace to cause problems aboard Galactica between the survivors from New Caprica and those who stayed with the fleet during the Occupation. Baltar assists the Cylons in an attempt to stay alive and uncovers details about Cylon civilization. A Cylon baseship falls victim to a mysterious disease.

Tyrol participates in the Circle, a secret tribunal on Galactica that tries and convicts in absentia those accused of collaborating with the Cylons during the Occupation. The death sentences–administered without the knowledge of Roslin or Adama–begin to weigh on Tyrol's conscience. Baltar faces a similar jury among the Cylons, who must decide whether he is allowed to stay with them.
