After the Black Team's devastating loss of Sarah, Ali acknowledges it's been a tough week - but the good news is this week, they'll have a little help. She brings in the Red Team to explain - this week there will only be one team: the Blue Team! The scale will be their one common enemy, and they'll have a chance to keep everyone safe. If as a group they can lose more than 64 pounds (the total of what everyone just lost), then they'll all have immunity. Hannah's not sure she wants to stop being competitive. Austin knows how hard they all worked last week. He's not sure they can make it over 64 pounds.
The next day, Dr. H comes to the ranch, and Marci and Courtney are the first to visit with him. The last time they spoke to Dr. H. nine weeks ago, Marci was shocked by what he said about Courtney. Now that mother and daughter have lost 158 pounds as a team, they hope Dr. H has better news. And he does! Midway through her journey, Courtney has only body fat, just like an average American woman, though ideally she'd be at less than Dr. H is happy to tell Marci that she's erased all her risk factors; her body fat is down to and in less than three months, she's at her ideal weight! Now it's time for her to go on a whole different plan.
Next to meet with Dr. H. are Moses and Kaylee, who last saw him in Week 2, when they had a real head-to-head. Back then, Moses didn't realize that what he was doing to himself was affecting everyone around him. The good news is Moses has gained 19 years of his life back; his risk of stroke and diabetes is almost nil. Luckily Moses isn't done; this is only the beginning! Dr. H asks a favor - will Moses do his part to help change the "eating-is-everything" Tongan culture? He will.
Ali meets with the Blue Team to announce a pop challenge, which will involve teams of two, one player from the former Red Team, one from the Black Team. The goal? Cook the best dish in 30 minutes. Two of the best chefs in the world (and from NBC's "America's Next Great Restaurant") are on hand to judge the competition: Curtis Stone and Lorena Garcia. Hannah is over the moon to see Curtis, claiming he's the only reason she wears makeup to the grocery store. This is her one chance to dazzle Curtis with her cooking! The winner will take home not Curtis, but The Biggest Loser Meal Plan, from the time they leave the ranch until the finale. And the players recipes will be posted on The Biggest Loser website!
The pop challenge competition is tough, and the judges are torn between Moses and Olivia's Baked Cod with Asparagus and Jenn and Kaylee's Turkey Tostadas. In the end, Olivia and Moses win the prize - and The Biggest Loser Meal Plan! Curtis claims their dish was just like something a chef would prepare.
Later on the Blue Team heads to the gym to surprise the trainers with this episode's twist. If they can lose 65 pounds combined, no one goes home. Bob loves it. The whole house will have to pull together as one, so no more games, just hard work. The trainers decide to split the group. Bob and Jillian take the guys and Brett and Cara take the girls. Cara immediately puts gloves on the girls and gets them boxing.
Finally, it's the day Bob's been waiting for. He's getting his hands on Rulon, and plans to "bury" him in the gym. On a break, Bob asks Rulon about why he's on the ranch. Bob explains that in order for Rulon to get his life back, he's got to regain balance. Rulon resolves to do it for his wife. After a talk with Cara, Hannah decides to let the word "redemption" carry her through her journey. Meanwhile, Marci overcomes her reluctance to box, realizing that with Cara, she actually likes it. And Jillian puts Austin through his paces on the treadmill. Afterwards, they discuss his potential. Justin's not sure what's standing in his way, but when he talks about his trip home, he breaks down. He feels selfish because he's on the ranch and his mom is not. However, Austin knows he can't fix his mom; he can only fix himself.
Later, the Blue Team heads downhill into a rock quarry for yet another challenge. They're going to follow a yellow rope buried underground across a rocky plain. As they follow the rope, they'll uncover trivia questions to be answered in teams of two. At each question post, another pair will join the group until all the questions are answered and the entire Blue Team crosses the finish line together. If a question is answered incorrectly, they'll have to go back and try again. The kicker? If they can complete the challenge in less than an hour and a half, they'll gain a five-pound advantage at the weigh-in. If it takes longer - they'll start the weigh-in at plus five. Knowing that it's a test of endurance, Marci and Rulon offer to go first.
The challenge turns out to be much tougher than anyone imagined - especially when Hannah injures her hand while digging and is pulled out. Ali sends Justin in to sub for her. Just as the clock hits an hour and 18 minutes, everybody's in for the final pull to the end of the course. But all of a sudden the rope starts turning - why's it taking them back to the start? Amazingly, the Blue Team makes it across the finish line with only six seconds to spare!
Later, Brett meets with Marci and Courtney to ask what they've been eating for dinner. Luckily, there are leftovers from last night - brown rice, salmon and vegetables - packed in Ziploc three-in-one VersaGlass containers - store heat and serve!
The trainers get deadly serious for the Blue Team's last-chance workout, and the players are pumped to be working together as a single team. They've got to beat 59 pounds!
Ali reminds the players that they have to lose a total of 59 pounds at weigh-in, which averages out to five pounds per person. If they fail to meet that goal, two people will fall below the yellow line, and the rest will have to vote to send someone home. Jen's up first, and she's thrilled to have lost five pounds after only losing one pound last week. Hannah's disappointed with her four-pound loss, but Bob assures her she's right on track. Still, he's shocked when Olivia has only lost three pounds - making the total so far 12 pounds. Everyone's hoping the big guys will pick up the slack, but surprisingly, Justin only loses five pounds. He wanted an eight, but he knows there's nothing more he could have done. Luckily, both Ken and Rulon lose seven pounds.
With half the players still waiting to weigh in, the Blue Team is more than halfway to 59 with a total of 31. Determined to help his team, Austin's hard work pays off with the biggest loss of the night - eight pounds! Still, the five remaining players need to lose four pounds each. Courtney's hoping to lose six, which would take her weight loss to 200 total pounds since beginning her journey. Courtney's not too disappointed to be two pounds shy of her goal - next week, she'll be there. Irene loses two and Moses loses six. This means two of the smallest women, Marci and Kaylee, have to lose four pounds apiece to achieve the Blue Team's goal. But Marci hasn't lost any weight! Courtney's freaked out, fearing that her mother may be going home.
Now all the pressure rests on Kaylee's shoulders - she has to lose eight pounds to keep everyone on the ranch. But somehow, Kaylee's gained two pounds! Bob and Jillian try to soothe her, promising they'll help even her weight loss out. Still, she's freaking out because she's not ready to go home. The Blue Team has missed their goal by 10 pounds, and since Marci and Kaylee are below the yellow line, they're both up for elimination. After the judges say goodbye, Bob tells the camera he hopes Kaylee gets to stay. For her part, Marci tells the Blue Team that it's her time to go; Kaylee needs to stay, and Courtney needs to stay focused. Moses promises to watch over Courtney like she's his own as Marci and Kaylee leave to await the Blue Team's final decision... which is the exact decision Marci asked them to make.
