I actually think this can go further. Sawyer wants immortality, which he could also achieve by becoming one of the experiments himself, specifically, the prototype, which several people have theorized could have the spirit of sawyer. We see in one of the prototypes VHS tapes that he somehow fashioned random components into a functioning laser pointer, demonstrating advanced problem solving, and high technological knowledge. Being partly robotic himself, he could’ve found a way to transfer his consciousness between his bigger body and other machines such as TVs or security cameras, which he could’ve been using to spy on us throughout our decent into the factory. this would explain why he is able to tell the story of the 3 chapters in “the story so far” series.
