Its a week of surprises for "The Biggest Losers," and the first is the news from host Alison Sweeney that theyll start competing as individuals now instead of as teams. Then comes the surprise return of all the eliminated contestants, and the revelation that only one gets to return to the game - and that decision wont be determined by weight loss. Then the contestants get a surprise visit from last seasons "Biggest Loser" - Alison Vincent! Later, two contestants clash in a big way before the challenge, in which contestants have to stay one step ahead of the competition - literally. And after the weigh-in, the players get their last surprise - a twist in how this weeks elimination will go down.
