During Chapter 9.2.4, he was believed (by Agent Griffin) to have found a large cache of the Intruder's override programs, and that a close examination of the programs unphinged his mind. This resulted in him thinking that he was an Agent, even going so far as dressing up as one and patrolling around Richland and Downtown. He also sometimes saying odd things such as long binary code. When he was encountered by an operative, Agent Griffin showed up and offered an explanation for his bizarre behaviour. It was hoped by the Machinists that Murphey might be able to lead them to the locations of the rest of the overrides.
