Ray shoots Danny much to his surprise, claiming that Zack is hers to kill and sew up. However, she remains conflicted since she has lost her faith in her God, meaning there is nobody left to forgive her for her crimes, and hesitates in shooting Zack. Pushing her down, Zack reminds Ray that he made the promise to kill her, not her God, shaking Ray back to her senses. The two swear to each other again on their vow and attempt to continue their way out. Although B1 is Ray's floor, she is unaware of its location even after knowing every nook and cranny of the place, deducing that the exit must be on B2 due to her floor being the last to be built and the strange observation that no one ever came down from above. While on the way to reactivate the elevator, she encounters Gray, with questions her intentions and her identity, telling him that she has accepted herself and will hence take responsibility for her own actions and choices from now on. Satisfied with her answer, Gray gives her a hint that the exit is behind the huge stained glass window of his floor. When Zack and Ray reunite, they try to find her gun as well but realize Danny's body is missing once again and that Ray's gun has been destroyed. Together they warily return to B2, where Zack smashes through the stained glass window to reveal a long flight of stairs leading to the surface. Just then, the building's self-destruct sequence is initiated.
