Sarah opens the airlock to silence Ruth

Sarah invites the skeptical Ruth to bear witness to direct proof that the spaceship is a deception by opening the airlock. The moment demands Ruth confront her fear of catastrophe against Sarah’s confidence, testing the fragile trust between allies and exposing the conspirators’ fiction to everyone present. The gambit hinges on Ruth choosing to believe Sarah’s judgment over her own instincts, a choice that shifts the balance of power inside the ship and seals the fate of Grover’s plan. Ruth’s resistance crumbles as the airlock fails to kill Sarah, rendering the conspiracy visible and irreversible to all aboard. key_dialogue: [ RUTH: But she'll kill herself! She'll kill us all! ADAM: (Sarah is inside the airlock. She opens the outer door and nothing happens. Smiling, she returns through the inner door.) If she's wrong, she's the only one that will suffer. ]
