EPISODE RECAP
Mark infiltrates Lumon's Testing Floor to rescue his severed wife Gemma, using violence and deception to access the Cold Harbor chamber where she has been repeatedly recreated as different versions of herself. After a climactic confrontation where Mark kills Drummond and retrieves Gemma, she briefly reintegrates with her outie self before Mark chooses to abandon her escape to run away with his colleague Helly instead, triggering a facility-wide alarm. The episode ends with Mark and Helly fleeing together through Lumon's halls while Gemma is left behind calling after Mark, their fates uncertain as the company's operations descend into chaos.
