It's early in the morning of Week 16, and the camera operators can't find any of the contestants - and none of them are wearing their microphones. A few of the contestants are eventually spotted going to their rooms, closing doors. Crying, Kim shuts herself into her bathroom, and it looks like Mark is - packing his suitcase? Supervising Producer Joel Relampagos finds Bob brushing his teeth in the makeup room and explains what's happening: The show planned to bring past contestants back to give them a chance to win a place in the finals, just like they always do. The final five got wind of the plan and are now threatening to quit. Bob can't believe it - it's insane. This happens every season!
By 8:55 a.m., Buddy, Cassandra, Jeremy and Mark are telling Producer Todd Lubin they're quitting - the situation is unfair. Todd explains that the legal team will be coming out to the ranch to talk to everyone, so there's still time to think before their decision is finalized. By 9:20, Bob is delivering the news to Dolvett. They head to the pool where the contestants are gathered to find out what's going on. Bob immediately asks Kim what's happening, but she doesn't want to talk; the situation doesn't involve the trainers. Buddy explains that they understand the trainers have a different opinion, but they're going to do this their way. Bob and Dolvett are dumbfounded. Mark explains they're upset that people who have already lost the game are being brought back for a chance to win. It's not fair, and they're taking a stand. Everyone's packed and ready to leave.
Later Alison brings Jeff Friedman, the show's lawyer, into the kitchen to meet the contestants. Jeff and Alison want to talk to the contestants one by one in the living room. Jeremy thinks it's a matter of right and wrong, and he thinks this is wrong - even though bringing back former contestants was part of his original contractual agreement. Jeff pulls out the contract to show that it does definitely say that all the eliminated contestants would be brought back for a final challenge. Kim insists she's not afraid to compete against anyone, but she wants to compete against people who deserve it - the final five. Buddy claims this type of game isn't a game he wants to win. Even though there are only two weeks left, Mark tells Alison he's no longer willing to make the trade-off.
As the day wears on, Kim decides she needs time alone to try to figure out what she's going to do. It's not long before Buddy and Mark load their bags into a van. Mark's done with the twists and the turns. Buddy's upset - he never saw things ending this way - but he doesn't feel like a quitter, even though he's quitting the show. Conda respects their choices, but she decides to stay in the game, along with Jeremy and Kim. Kim feels sad to say goodbye to Mark and Buddy; she'd far prefer to compete with them. But right now she's thinking about all the hard work she's done and the hard work she wants to continue to do for herself and her kids.
The next morning, the remaining three contestants put their Biggest Loser shirts back on and head to the gym. Alison is waiting for them, with congratulations for seeing the game through until the end. This week's excuse is "I lack motivation," and Alison has something to help motivate the players through the week. She runs into the gym, then returns in a brand new Ford Escape - which one of them will win! The player with the highest percentage of weight loss is going to drive it home. This week, there will be a red line at the weigh-in, and the player with the lowest percentage of weight loss will fall below it and automatically be eliminated. The other two will have a guaranteed spot in the finals.
Bob and Dolvett are waiting in the gym, happy to see that Conda, Kim and Jeremy have decided to stay. Bob immediately takes Conda outside to check out the Ford Escape, review all its cool features and take it for a ride. He stops the car at the prison yard, on the pretext of picking up some equipment. He returns with a harness - Conda's going to put it on and pull Bob in the car. Determined not to fall below the red line, Conda puts on the harness and starts hauling. Then Bob has her run back to the gym to join Dolvett, Kim and Jeremy.
After their workout, everyone meets up in the kitchen for lunch from Subway. Bob and Dolvett wrangle the contestants and bring them to the gym for a surprise. They've got a video montage of the contestants from when they first came to the ranch, which goes on to track the progress of their last four months. Finally, it's time for perhaps the most important weigh-in of the show. Two of the three remaining contestants are going to the finals and one person is going home. Not to mention that someone's going home with a brand new SUV!
Conda's first to weigh in. She started off the week at 205 and has lost 10 pounds which puts her into the 100s. Bob remarks that Conda has battled her demons and won. Kim's up next. She started the week at 162 - and is now 147 - it's a stunning 15-pound loss at Dolvett is over the moon, complimenting Kim's inner tiger. No matter what, Kim's in the finale! This means that Conda and Jeremy will finally be split up - one of them is going home. Walking up to the scale, Jeremy's feeling that he deserves to be a finalist; he knows that he worked out harder than anybody this week. Alison informs Jeremy that he'll have to lose 12 pounds to stay in the game, but he only loses 10. Outraged, Conda starts crying - if anyone deserves to be in the finale it's Jeremy, and it's just wrong! Jeremy knows there's nothing bad about losing 10 pounds, and he's resigned to his fate. He's going home, and Conda and Kim are going to the finale.
But the show's not over yet... After congratulating Kim on her brand new car, Alison has yet another surprise in store. The doors open, and the 14 previously eliminated contestants pour through them, to take their spots standing next to Jeremy. Now what?
