Plot summary
Because the entity's powers allow it to access any information Claude knows, the group decides to distract him while they search for it. The investigators manage to arrange interviews with the boy who had been lured by the entity and with the boy's grandfather. The boy explains the entity's description of a potential bear cave, while the grandfather describes being unsettled by the entity's face seeming mask-like. A parallel story during the episode, about a father searching for his two boys, is revealed to occur over 70 years earlier, in 1947, when the bear cave collapsed.
The 34-man search party, which included some of Claude and Seale Bolton's ancestors, starved to death after being trapped inside the cave. Due to the location's tragic history, which also involves the Bolton family, the investigators conclude that this is where the entity is hiding. Additionally, while this is occurring, D.A. Hayes learns of another young boy who has been killed in a manner similar to Frankie. Ralph, Holly, Yunis, Alec, and Andy travel to the cave. Seale, recklessly yet intentionally, reveals the plan to Claude, immediately alerting the entity to the situation; the entity forces Jack into action. Once the five investigators arrive at the site, Jack (a trained sniper from his military past) uses his sniper rifle and begins a deadly round of shots, one of which kills Alec.
