Ep. 7: Kaoru crafts tools while the group searches for the missing trio who reach an island peak

7

Kaoru shapes obsidian into a spear and knife, while Chako and Shingo struggle to fish without hooks. Bell and Sharla successfully start a fire through teamwork, rubbing their hands raw. The group worries about Luna, Menori, and Howard, vowing to search at sunrise. Kaoru learns from Bell that fish must be cleaned, realizing everyone must collaborate, so he crafts bone hooks and additional knives. Meanwhile, Luna, Menori, and Howard spend the night in a cave before reaching a mountain summit, discovering they are on an island. Initially depressed by the lack of people, they recover their bearings, map the island, and collect water before heading back toward the shuttle, eventually reuniting with the others who began searching for them.
