More Questions About Lily Chan
Devs is about Lily Chan uncovering Amaya's cover-up of Sergei's death and discovering a machine that turns grief, prediction, and free will into a moral crisis.
Lily throws away the gun because she has seen Devs predict that she will shoot Forest and refuses to let that image determine her action.
Jamie is Lily ex-boyfriend and a cybersecurity worker who helps her investigate Amaya, then is killed by Kenton.
Jamie helps Lily because he believes her, still cares about her, and has the technical skill she needs after Amaya isolates her.
The ending means Forest's deterministic certainty fails, but Devs remains powerful enough to create a morally serious simulated afterlife.
Devs does not definitively prove free will, but Lily's refusal to shoot Forest is the strongest challenge to strict determinism.
