Ali meets the teams at the start and tells them this week is about choices. Then she gives all the teams an offer: first to step over the line loses their trainers for the week but gets a 2 pound advantage. If no one takes it, “the stakes will go up.” Most of the teams don’t look very interested, but then suddenly Tracey from purple team steps over without ever consulting her teammate. She says it was to prevent others from getting a bigger advantage. Coach Mo looks shocked and reveals to the camera that he’s unhappy about it.

Later, when Bob and Jill arrive, they’re pissed as well. They discuss how tons of people are willing to do anything to spend just one day with Bob or Jillian, and she threw it away for 2 pounds! They talk to her about stopping and thinking, staring fear in the face and not panicking.

Dr. H. meets with Abby and tells her she has a stress fracture in her knee; she can do swimming but no land-based exercise until the pain goes away.

Ali next arrives with a temptation: you can choose to control your diet or control the game. She then reveals a cupcake to each of them and says it has 100 calories. The players are all in booths so they can’t see each other, and she informs them that only one person per team gets to weigh-in this week, and it will be decided by the winner of the temptation. The temptation is to eat the most cupcakes in ten minutes. Antoine is the first to eat one at around 4 minutes and Ali tells the rest of the players that “someone is now winning this game.” Tracey totally freaks out and starts chowing. Towards the end, she tells the camera that she’s feeling sick and just wants the challenge over. When time expires, Ali reveals that only Antoine and Tracey participated. She says Antoine didn’t win, eating two cupcakes; Tracey ate four and wins control. When Bob and Jillian find out, Jillian is furious and basically says she’s done working with Tracey. She says she wants to go over there and throttle her, and Bob later laughs about it with the camera.

For the challenge, the winning team will get immunity. The task is to carry 500lbs up a ramp with either 2 x 5lbs per trip or 1 x 25lbs from farther away. Tracey and Abby have to sit out because of injuries, and the single players (Mo, Julio, and Allen) will each do half the weight. The competition really isn’t that close, and the 25lbs weights end up being slower it looks like. Green (Allen) wins by a couple trips over the next team, but all the teams complete the challenge. Everyone helps Mo finish his load at the end, and it looks like he still had quite a few trips left.

A few of the teams speak with Tracey in private and look to get some sort of confirmation on who she’s planning to have count. Orange (Daniel and Shay), pink (Amanda and Rebecca), and brown all talk with her. She doesn’t really give a clear view of where she’s going, although she does agree with Daniel that “Shay has to be here.”

At the weigh-in, Jillian rips on Tracey again, and chastises Mo for offering her any support. She accuses Mo of just letting it happen and not letting her know how it affects him, which from the episode appears accurate. As the teams weigh in, Tracey betrays all the teams that confided in her and chooses the opposite of what they wanted. It greatly affects the results for a couple teams, and Jillian comments to the camera that it’s one of the nastiest examples of game play the show has ever seen. Ultimately, all but purple have weighed in, and Tracey chooses her weight to count. In a surprise result, she loses 11 pounds, making her the biggest loser of the week – even before the 2lbs bonus. (No one cheered for her) Red team and orange team end up below the yellow line. (Note that had Tracey not been ruthless, i.e. if she had selected the “better” player from each team, brown and orange would have been up for elimination.)

Going into the voting, Antoine and Sean say they have a good support system and are willing to go so that Shay can stay. There are lots of tears at the voting, but the first three teams respect their wishes. Tracey/purple is the last vote shown, and she says two teams still would have fallen below the yellow line, with or without her, and someone would have been making the decision. She then says, “I told you I wanted Shay to stay here, and I wasn’t lying.” Then she reveals that she also voted to send red home.
