Kennex is then recalled to the force by Captain Sandra Maldonado ( Lili Taylor ), and partnered with a standard-issue MX-43 android, which he soon throws from a moving vehicle, when it threatens to report his unusual behavior. He is assigned a replacement android, an older DRN model originally decommissioned for police work and about to be transferred to the Space Station.  Created to be as close to human as possible, the DRN androids have trouble dealing with some of their own emotional responses, which was the reason they were replaced by the logic-based MX units.  Kennex's unit, known as Dorian ( Michael Ealy ), immediately proves himself unique, with a clear dislike of being referred to as a "synthetic", and a dry, friendly, sarcasm-oriented wit. Key to the story arc is the growth and development of Kennex and Dorian's relationship.
The eye, like a top-of-the-line modern camera, contains a self-adjusting aperture , an automatic focus system, and an inner surface that minimizes the scattering of stray light. But the sensitivity range of the eye, which gives us excellent vision in both sunlight and moonlight, far surpasses that of any film. Its neural circuitry enables the eye to automatically enhance contrast. And its color-analysis system enables it to quickly adjust to lighting conditions (incandescent, fluorescent, or sunlight) that would require a photographer to change filters and films.
