Passage: Henry and Delilah discuss destroying the government camp, but decide against it. As Henry hikes home, someone sets fire to the camp. The next day he uses the tracking device to find a backpack with a key to the cave. Delilah reports a figure in Henry’s tower; when Henry arrives, he finds a Walkman taped to the door with an incriminating recording of Henry and Delilah's discussion about destroying the government camp. When Henry enters the cave, someone locks the gate behind him. He escapes through another exit and discovers Brian's old hiding spot, where he went to escape his father when he tried to teach him how to climb. He goes deeper into the cave using climbing equipment left at Brian's camp, and discovers Brian's decomposed body at the bottom of a cavern. Delilah is upset by the news, blaming herself for allowing Brian to stay. The next day, the fire at the government camp has grown out of control and an evacuation order is given for all the lookouts.
