and six other victims: Xavier, Jonas, Laura, Addison, Obi, and Gus. A nerve agent filling the house will kill them all within two hours, but John assures Matthews that if he follows the rules of his own game, he will see Daniel again. At Kerry's urging, Matthews agrees to buy time for the tech team to arrive and trace the video signal. During their conversation, John reveals to Matthews that his main motivation for his games was a suicide attempt after his cancer diagnosis, which led to a newfound appreciation for life; the games are intended to help his victims develop the same appreciation.

Xavier enters the room and leaves her to die after reading her number. Amanda and Daniel find a tunnel from the first room leading to the dilapidated bathroom. After Xavier corners them, Amanda taunts him by implying that he will not learn
