Previously on Survivor... At the immunity challenge. Each castaway had to hold a set of ropes balancing a white ball on a platform. At different intervals, castaways extended to the next knot of the rope making it harder and harder to balance. If their ball drops, they're out. Last person with their ball on the platform wins immunity. And it was Joe who took the win guarenteeing himself a 1 in 9 shot at winning the game. At tribal it was Amber blindsided by a 7 to 4 vote making her the 3rd member of the Jury.
