The Pink Team is next, and go for the immunity. There is one spot left with the unknowns. The Red Team takes it. This means that Orange, Blue, and Black go with Bob and Jillian by default. If I were them I'd pretend that I would have chosen them anyway. It might fend off the rage momentarily.

After a commercial break, the six lucky teams meet Bob and Jillian in the gym and explain the situation with the mystery trainers. Bob and Jillian seem kind of surprised, but they had to know about this going in, right? Bob actually wonders what the teams who chose them were thinking, since four weeks of immunity is a giant gargantuan mondo prize. The biggest in Biggest Loser history, in fact! Add this to your at-home drinking game: a shot whenever someone says "in Biggest Loser history." Bob and Jillian's reaction freaks Courtney out, and makes her rue her natural loyalty. Bob tells the contestants that unfortunately, no matter how hard they work, four people are going home in the next four weeks. So from here on out, Bob and Jillian are going to prep them for everything and anything.

With that, it's Bob and Jillian's day one workout! Jillian says she doesn't want to yell, which is a lie. Basically, when she tells someone to do something, she wants them to do it. Not because she yelled, but because she said so. Bob doesn't buy it, either. He says that asking Jillian not to scream is like asking the grass not to grow, and the fish not to swim, and the lions not to roar, and the recapper not to eat cookies to make it through the second hour of this fucking show. Basically, Jillian is always going to yell at people.

Ana of the Orange Team says that she was very nervous, and hadn't been on a treadmill before their challenge. She has bad arthritis in her knees, and doesn't know how she's going to get through it. Arthur is almost 80% body fat, and is going to need a lot of attention. He squats and gets stuck for a minute. Arthur tells us that it's daunting and frustrating to have so far to go. He has to lose 300 pounds, which is the weight of his awesome and adorable father. Jennifer of the Green Team says that she and her dad didn't want to go to the unknown trainers because Bob and Jillian have a proven track record. Also, they will yell at you. Jennifer is sort of scarily intense. I hope Dr. Phillian gets a round with her. Bob tells us that Courtney is a machine. She keeps going and pushing, and does everything that Bob asks. He thinks that Courtney can go all the way. Courtney agrees. She says she wants her competitors to know that if the biggest girl in the house can do it, they can do it too. Jillian screams at Dan/Don that she wants to see agony. I certainly see it.
