Alison waits for the contestants in the living room, standing next to what looks like a voting booth, to announce that the game is about to get much harder. This week, they'll be competing in a pentathlon - all week long. If that's not enough, they're going to singles, and for the first time this season, they'll have to contend with a yellow line. Five events will be spread out over the week, and at the end, the person with the most points wins immunity - and the person who comes in last will get a one-pound disadvantage on the scale. The first event starts now, and it's a test of merit. Each player will rank the other players, and the player who comes in first will receive seven points; the next player will receive six points, and so on. They'll find out the results of the first event at the weigh-in. Vinny's up first, and he has one minute to make his decision. Every player has a different strategy, and the pentathlon is on like donkey kong.
