The Blue Team has an hour to formulate their decision. They're all sick of losing. Aubrey pleads her case, saying that none of them are ready to go home, and all of them need to be there. Cathy volunteers to go home, saying that she's strong enough to do it at home. Aubrey feels bad about that. Apparently they're very close. Aubrey would never ask Cathy to leave her daughter, but at the same time she wants to stay on the ranch. Tears. Kristin doesn't want to lose her mom, who is her biggest ally, and struggles as to whether she should respect Cathy's wishes to go home.

In the judging room, Aubrey votes for Cathy, as does Ron. Kristin struggles with her decision, but in the end goes with Cathy herself. Cathy handles it all in stride, with a whole lot of grace. She hugs everyone and tells Kristin that she's in good hands. Cathy exit interviews that she's shocked she's made it this far, and is proud of the accomplishment she's made. Exercise is empowering, she says, and she's determined to not be a quitter now. Bob has shown her that she can do it, and she wants to inspire others to change their lives as well. She gives a shout out to Kristin, and tells us that she's going to be 80 pounds thinner and we won't be able to tell who's the mother and who's the daughter. At home, Cathy has developed a new addiction: spinning! Her daughters are doing it, too, and are all losing weight along with Cathy! She says that when she's done with this she'll be so powerful, because she'll be strong emotionally and physically. And it doesn't get much better than that! Cathy and her daughters have lost a total of 141 pounds.

Next week: Will it be the first time a woman loses 100 pounds? I'm guessing yes.
