Olivia reveals that she's contacted the Black Team's family members, and has some special gifts. Becky gets roses from her husband, and everyone gets a scrapbook. Becky points to a photo of her wearing her wedding ring, and notes how heartbreaking it was that she got too big to wear it. One of her goals is to slim down her sausage fingers. Vinny's scrapbook was constructed by his fiancé, who looks adorable and also quite stacked. He explains that he initially told her that he didn't want to be in a relationship, both because he was a working musician on the road and because he'd had his heart broken previously. But she was convinced that Vinny was the love of her life, and wouldn't let up. Vinny tells us that he wrote a song for her on the ranch, called, "The Worst Days With You Beat the Best Days Without." He misses her lots. Antone's book was put together by his wife, and as he flips through he starts bawling. He notes how big he looks in the photos, and says he realizes that all this time he's not really been able to do things with his kids. He was an observer and a bystander, and it makes him very sad. Olivia tells the three Black Team members that the work they're doing on the show will have a ripple effect when they get home, transforming their families and encouraging others.

Meanwhile, the Blue Team is back on the tennis court. Sunny loves it, and says she'd be out there for every workout if she could. It turns out her husband was a tennis pro at the local club when they first started dating, and she always rejected his requests to play mixed doubles. She was embarrassed to go out there as his "big fat wife." But that's changing! Biggest Loser: bringing families together, on the court and off. Anna gives Sunny big kudos for her drive and commitment, and tells her to be proud that she's working her ass off. Sunny is, well, sunny. You know, happiness, what have you done today to make you feel proud, etc.

Hour two begins with visits to Dr. "Death" Huizenga. Oh, goodie. Though this is the point in the season where his news tends to be a bit less dire, at least. He has a friend with him -- it's "an unbelievably qualified expert" from Johns Hopkins named Dr. Linden. He's a brain scientist, and is interested in what happens in your brain when you get pleasure from food. By the looks of this guy, I think he's also developing sentient robots who will take over the planet. I don't know, it's just a feeling I get. He plays a little video for Bonnie that shows a creepy animated lean person smelling a hamburger. The lean person is not even that excited about it. Now, as a lean person myself, I'm calling bullshit. My brain gets PLENTY thrilled when I smell a burger. The video then shows a creepy animated obese person smelling a hamburger. The pleasure center gets all big and red in this case. Just imagine if that animated obese person had smelled an animated donut!
