Their partnership was an odd one, most would expect it to have failed a long time ago. A known android hater being willing to work with an android is unlikely, but they made it work. RK900 was happy to let Detective Reed lead, simultaneously assuring the human that he wasn’t going to be replaced and allowing the android to do his work with as little social interaction as possible. Detective Reed seemed to perceive him as just being a tool he could use at a crime scene or in an interrogation, but RK900 didn’t mind. One wouldn’t try to have small talk with a piece of equipment.
