Last-chance workout! Yelling, sweating, beatings. Mike is amazed at his own transformation and says that while he had no hope before, now he's bulletproof. Aw, I really love that kid and am so happy he's done so well. He's going to be the hottie who amazes everyone by busting out that he used to be 400 pounds. Everyone is working it out to increasingly furious degrees, and Jillian has her team doing two-minute sprints. Helen quits with a few seconds left, and Jillian screams at her. Helen does not quit the next time. She does, however, feel like she might die. Bob is no easier on his team members, all of whom are in some pain. However, Kristin says that she's breaking barriers every single day, which is a good feeling. If Kristin can spring with all that boobage the rest of us really have no excuse. Jillian screams at her team that if they go home and think they're going to win this show, they have to be exceptional. So she's having them do one more sprint. We cut to commercial after she says this, which actually makes me feel like someone might die.

Actually, no one dies. But Jillian tells us that these intense workouts tend to destroy all the contestants' walls and barriers. Mike is pushed beyond his limit, and tells us that he was pissed off. He punches the treadmill, which I think is probably a substitution for Jillian. Jillian interviews that Mike is always going to have a fat kid inside. Every time he fails or struggles, he thinks that he's always going to be a failure or a loser and unravels. He cries and bites his sleeve, and Jillian asks him what he's pissed about. She tells us that being 300-plus pounds as a teenager comes with a lot of heartache and a lot of anger, and is generally soul-crushing. That's been brewing inside of Mike for 18 years. She notes that when Mike got here he was almost 400 pounds, and Ron was over 400 pounds. There's obviously something going on in the family.

Mike tells us that Jillian recognized his bottled-up fury. Jillian gets right to the point and asks Mike if he ever blamed Ron. Mike says he didn't. He always blamed himself. He never thought he would get as big as his dad, but then was over 400 pounds when he graduated from high school. Jillian asks, "You don't think your family had anything to do with that?" Mike acknowledges that they'd go out to eat all the time, but he was choosing his own food. Jillian tells him that he was a child. Mike starts to defend his parents, but Jillian tells him again that he was a child. She needs him to communicate with Ron, express his feelings and anger, and know that with communication they can create a different life together. She gives Mike a big hug, and sends him off into the emotional wilderness.
