Stewart
Stewart is an older Devs engineer who sabotages the magnetic elevator because he believes the project has crossed an intolerable line.

Episode Timeline
Sergei is invited into Devs, sees the projection system, copies code, and is killed by Kenton while Lily is told he committed suicide.
Lily rejects the suicide story and turns to Jamie, while Forest and Katie watch events with the confidence of people who believe the outcome is already known.
Lily and Jamie uncover Sergei's espionage, and Kenton tightens the cover-up around them.
Amaya uses Lily's psychiatric history to discredit her while Devs demonstrates its ability to reconstruct the distant past.
Lyndon's many-worlds method makes Devs clearer, but Forest fires him because the improved model threatens the uniqueness of Amaya.
Katie's bond with Forest comes into focus, and Lyndon dies at the dam after accepting her many-worlds challenge.
Lily reaches Devs and sees the prediction that she will kill Forest, making her knowledge of the forecast part of the event itself.
Lily throws away the gun, the elevator crashes, and Katie places Lily and Forest into simulated branches after their deaths.
