As the sun sets, it starts raining heavily. The group takes refuge in a cave, where Plazz finds cave art. When Nikki tests the “paint”, she discovers that it is blood of some kind and only a few months old. Harlan finds a shell near the cave’s entrance that Tara wore as a necklace and the next day they search the area but don’t find anything else, moving on. After another full day of searching with no results, they set up camp near a natural hot spring. Marla talks with Harlan at the spring away from the others, revealing she knows about the project Tara had been working on and that without the prototype Tara had with her, his company is practically bankrupt. She blackmails him into keeping it quiet from B&B in return for 30 million in Bio-Comp stock. Around the fire, Clayton confronts Burg about the claims he’s made in his survivalist books, having noticed his many flaws as they have been tracking the plane’s last known movements and Burg threatens him.
