The teams are roughly neck and neck at the last challenge. Ada takes it for the Black Team, and has to guess, within 100 calories, how many calories are in a big hunk of lasagna. She guesses 1850. This is incorrect, and the Black Team learns that they must run 21 flights of stairs. Mark takes it for the Blue Team and guesses 1300 calories. This is also not close to the actual calorie count of 804. The Blue Team thinks this is where they can catch up. They're on the second floor while the Black Team is on the sixth. Anna tells us that there's no way she can make it up twenty-one flights. Ada makes it up to the top first, while Liz is way behind. Frado hopes she isn't having an asthma attack or stuck somewhere. Ada takes action and runs down to help her. And then the Black Team makes it to the finish line first and rings a bell made of letters. Despite all the talk of the Blue Team being close, they're nowhere in sight. They finally make it to the top, dejected. Lisa cries because she wants her damn letters. Ada is pained to see that the others are in pain. Brendan says that he wants his letters really badly, but he wants Lisa to have her letters. He knows how much she loves her kids, and he doesn't love his mother and father nearly as much. Anna volunteers to give up her letters, as does Ada. Her parents would only insult her anyway. Frado follows suit. What an odd gesture of kindness just as they're planning sabotage!

Cut to the gym, where Rick and Brendan try to convince Jillian that Bob told his team that the Black Team would throw the weigh-in and thus they had to do what they had to do. Which I guess means also throwing the weigh-in? In any case, Jillian did not just fall off the organic turnip truck. She says, "I'm not an idiot. You're throwing the weigh-in. You got caught. Don't treat me like I'm stupid, I've been doing this forever." Too true. Jillian says she can't tell the guys how to play the game, but reminds them that they're in this to get healthy and should try to stay focused on why they're there. As Brendan tells us about the importance of strategery, Jillian complains to Bob that he usually gets the big doofuses, but they are hers this season. Bob simply says, "You can have them." I can't believe that Brendan was once my favorite. I feel so duped. Jillian says she'll be pissed if their plan is throw the weigh-in and get rid of Anna. Bob is all, "Who else are they going to get rid of?" Jillian looks pre-emptively pissed. She and Bob seem to employ a similar strategy, which is: beatings of their lives.
