Why does Percy suspect that Ares wasn't acting alone-that he was taking orders from someone?

Percy suspects that Ares wasn't acting alone because the God of War's behavior seems unusually orchestrated, indicating that his actions might be motivated by a greater force. Furthermore, the complexity of the conflict and the specific targets involved suggest a strategic plan rather than random aggression. Percy’s instincts, honed through his experiences, lead him to believe that there is a puppet master behind Ares, manipulating events for a more sinister purpose. This suspicion is reinforced by the patterns of deceit and manipulation he has encountered in the world of the gods.
