Ep. 14: Ray and Zack swear to kill each other while navigating the building's levels and facing a self-destruct sequence.

Ray shoots Danny, asserting her right to kill Zack, but hesitates due to lost faith in God. Zack reminds her of their mutual vow, prompting them to swear again and seek an exit. Ray deduces the way out is on B2, as her floor was built last and no one descends from above. She encounters Gray, who questions her identity; she asserts her acceptance of self and responsibility. Gray hints that the exit lies behind a stained glass window. Upon reuniting, Zack and Ray find Danny’s body and Ray’s gun missing. They proceed to B2, where Zack breaks the window to reveal stairs leading to the surface. As they prepare to leave, the building initiates its self-destruct sequence.
