So apparently at the Final 6 reward, Sarah/Troyzan/Brad all got talking and they were saying how they couldn't trust Sarah, so Sarah gave up her bracelet to them saying that if she lies to them they can keep it. Troyzan also gave up a bracelet. Brad had nothing on him so Sarah was like, "I want your wedding ring, and if you screw me over I'm throwing it into the bottom of the ocean."
