But the pressure is on when they find out their weight will be the only weight that counts for their team this week on the scale. While the chosen contestant deals with the emotional issues at home that caused them to gain weight, the remaining team members try to stay on track at the ranch without their trainer. Later, the two eliminated contestants at "Comeback Canyon" compete to stay there one more week, while the ranch weigh-in finds one player making the ultimate sacrifice for their team."
