The 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), after being shot by Specialist Cally ("Resistance") 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.
