"Downloaded" is the eighteenth episode of the second season of the reimagined Battlestar Galactica television series. It aired originally on the Sci Fi Channel on February 24, 2006.The episode takes place alongside the rest of the re-imagined series, with 49,579 human survivors left in the Fleet. The episode primarily details the lives of two specific Cylon models after their apparent destruction who were declared Cylon heroes. One model is "Caprica-Six", the copy of Number Six who was responsible for disabling the Colonial defense system prior to the events of the miniseries. The other model is Sharon "Boomer" Valerii, a sleeper agent who was a member of the crew of Galactica.The concept of a Cylon-centric episode was proposed long before the episode aired, in an episode which would have seen the Cylons discuss their equivalent of the "Final Solution". "Downloaded" instead focuses on showing the personality of the Cylon race, in particular, Caprica-Six and Boomer. The episode was universally well-received despite its unconventional format.PlotThe episode primarily takes place on Cylon-occupied Caprica. After the Fall of the Twelve Colonies, the copy of Number Six (Tricia Helfer) that was responsible for disabling the Colonial defense system (affectionately known as "Caprica-Six") and Sharon "Boomer" Valerii (Grace Park) were both "downloaded": a standard Cylon practice of rebirth which takes place if a model is to perish, and have both been hailed as Cylon heroes due to their efforts in infiltrating human society.
