chunk: Armed with a syringe of nanites from Calvin's laboratory, the three head to VIKI's core. VIKI unleashes an army of robots to stop them. As they battle the robots, Spooner dives into VIKI's core and injects the nanites, destroying her positronic brain. Immediately, all NS-5 robots revert to their default programming and are decommissioned for storage by the military. Sonny confesses that he killed Lanning, at his direction, to bring Spooner into the investigation. Spooner explains to Sonny that he is not legally responsible since a machine, by definition, cannot commit a murder. Sonny, pursuing a new purpose, goes to Lake Michigan and becomes the leader he saw in his own dream.
