The final nine contestants are delighted to learn from host Alison Sweeney that the game is now going to singles and they'll all compete as individuals for the rest of the competition. Then she reveals a big surprise - the eliminated contestants have returned to try and win a spot back in the game. But for the first time in Biggest Loser history, the player chosen won't be determined by weight loss, but rather by popular vote. After that contestant is voted in, the remaining eliminated players get to battle it out for another spot back in the game - going to whoever wins a 1,000 step-ups challenge. Later, a close friendship starts to unravel, and after a tense weigh-in, another contestant is sent home.
