Due to Alison Sweeney giving birth just after the previous week’s elimination, Ali Vincent, The Biggest Loser Season 5 winner, shares hosting duties with Michelle Aguilar, Season 6 winner. As the episode begins, the three players whose on-campus partners were eliminated in the first few weeks of the season return for a chance to rejoin the ranch. The players are Estella (White Team), Nicole (Red Team), and David (Orange Team), and the person with the highest percentage of weight loss will return and have immunity for the week. Estella loses 45 pounds, or 18.59%. David loses 46 pounds, or 11.70%. Nicole loses 87 pounds, or 32.34%. Nicole is thus the winner, and in fact has lost a higher percentage of weight than anybody on the ranch with the exception of Tara. Nicole begins training by Bob, while all of the players try to win her over to their side.

Meanwhile, Ron experiences chest pains, dizziness and nausea, and is sent to the hospital. Dr. Huzienga explains that Ron is bleeding internally, but a heart attack is ruled out. Tests show that he has two bleeding ulcers. The problem is fixed, and Ron is also treated with bloat-inducing red blood cells and fluids, and released.

Bob is shown focusing his attention on Sione and Kristin, his most promising trainees; he emphasizes to them that they must never quit. The challenge this week, moderated by Michelle Aguilar, involves contestants balancing on a platform above a swimming pool, with each platform supported by 40 ropes. The ropes are cut one by one, with the last person still balancing on their platform the winner. The prize is a one pound advantage at weigh-in. Nicole, who has immunity, will instead win a one pound penalty for the person of her choice. Sione, inspired by Bob, wins.

Alison Sweeney returns for the weigh-in. To everyone’s shock, Nicole has gained 5 pounds, and because of this, she loses her immunity. The rule, already in place on the Australian Biggest Loser, is that if a person with immunity gains weight, they will lose their immunity. The rule punishes “water-loading”.

Mike is the Biggest Loser for the week, and Ron and Nicole, both of whom gained weight, are up for elimination (Laura also gained weight, but it was not enough to place her below the yellow line). During deliberations, Filipe and Mike have a confrontation over the previous week’s elimination, in which Ron had argued for voting off Filipe instead of Aubrey, which Filipe sees as a violation of their alliance. Thus, Filipe, Sione, and Helen vote for Ron, but Tara, Laura, Kristin, and Mike vote for Nicole, eliminating her for a second time from the game.

In the video update, Nicole is shown trying on a size 12 wedding dress (a contrast to her previous size 24 dress). She has lost 105 pounds and hopes to fit in a size 8 wedding dress for her wedding in June.
