After a week and nearing the end of their supplies, Sloan suggests heading back. As the two are packing their gear, they are suddenly attacked by Cheyenne Indians. Sloan, speaking the Cheyenne language, deescalates the situation, and the two are taken captive by Yellow Wolf. They are taken to the Cheyenne encampment in a valley accessed through a tunnel behind a waterfall, where the duo meet the village leader Spotted Elk. He tells them of the escape and salvation of the Cheyenne 128 years ago, as well as his own run-in with the "white people" when he was a child.
