When the castaways get word of the upcoming challenge, one with a huge reward, they all work their hardest to win. The tough challenge results in a big win for Casaya, and the team collectively wins the prize, which includes immunity, the choice of which member of La Mina goes to Exile Island, and the chance to visit a Panamanian town and distribute toys and food to the children there. During Casaya's trip, the tension that occurred prior to winning, the apparent break-up of the Shane-Aras-Courtney-Danielle alliance, was forgotten, and all enjoyed the reward. Meanwhile, at La Mina, Sally, the last woman on the tribe, is saved from certain elimination when Casaya sends her to Exile Island, and while she is gone, Dan reveals his astronaut past to the rest of his tribe. Whether or not this fact has any bearing on that night's decision is trivial: Terry sides with the younger men, Nick and Austin, and Dan's torch becomes the sixth snuffed out.
