Recovery One (2) - S0.E41

Washington attends to a dead soldier who put out the distress call. There is also a female soldier named Sally at the scene. Washington refers to them as "North" and "South" respectively for North and South Dakota,[4] indicating that they too are among the AI-implanted soldiers. Through their conversation, it is revealed that the female and the deceased male are twin siblings and that the brother's AI, Theta, is missing. Washington receives an order from his command post that the recovery of Theta is top priority and that the current situation was "Priority Zero," and had to be contained. He hesitantly accepts the order, and appears to have killed South with a pistol shot to her head.
