A quote of something N has said before: "Other than ingesting their WARM, SWEET oil to avoid overheating and dying, I guess I just wanna be useful." Him talking about killing worker bots. N is kind, timid, socially awkward and caring. He wanted to be friends with or at least be accepted and acknowledged by his squad, but because of his naïve and good-natured personality, he ends up being ostracized. Disassembly Drones eat the oil of Worker bots. He only leaks oil, no blood. Nobody is human.
