^Now I get it why almost all characters in Devs had this wooden acting since Episode 1. It seems the entire series was a simulation designed by the quantum machine to determine the best possible deterministic path for all characters, including that of Forest, Lily, Sergei, Jamie, Lyndon, Stewart, and even Kenton. It seemed like only Katie was the real world character who was looking into the simulation and determining the responses of each individual character. In the end, what the result of their overall interaction was resolved the many-worlds deterministic theory proposed by Lyndon and affirmed by Katie that set up the finale as it were. Great writing, Alex Garland.
