Why Aren't You Swimming?!

S13 E8: After one castaway collapses from exhaustion during the Reward Challenge, the burden of completing the challenge is left to their other tribemates. When one Survivor chooses to sit out the physical portion of the Reward Challenge, the rest of the tribe becomes resentful of this person after their loss. With little shelter available, a raging storm makes one castaway's trip to Exile Island a nightmare. And, the eighth castaway is voted off the island.
