Late in the war, it is revealed that Sikozu is a spy for the Scarran Empire in exchange for a promise from them to free her people from servitude. Scorpius assaults her after revealing his knowledge about her betrayal and leaves her to die on the water-planet, Qujaga. This development is foreshadowed in several earlier episodes: At their first meeting, Chiana thinks that Sikozu is a spy because she has Scarran currency and speaks Scarran. Sikozu explains this by saying that her people are from Scarran-controlled space. In a visit to an unrealized reality, Crichton — in that reality, a ranking Peacekeeper officer — is forced to execute Sikozu after she is revealed to be a Scarran spy.
