S10, E5: Five contestants who didn’t make it to the ranch in the premiere episode now return, all vying for a spot back in the competition. Whoever has the highest percentage of weight loss wins their way back in, and also wins one of the most important, game-changing decisions of the season when the competition moves to blue team vs. black team this week. In their first challenge as blue team vs. black, they race through food stations in downtown Los Angeles, answering food trivia questions that come with a physical challenge penalty if they choose the wrong answer. And the stakes are high with the winning team getting "The Biggest Loser" meal plan by Ediets for each member, plus the always-coveted reward of letters from home. When one team proves victorious, members of the losing team get a heartwarming surprise. Later, the drama heats up when a rumor spreads of one team possibly throwing the weigh-in, and after a tense weigh-in, the players send another contestant home. Alison Sweeney hosts the series, and trainers Bob Harper and Jillian Michaels also star.
