(S09E12) Is there any point in saying it was a crazy week in the house anymore? The producers seem determined to make every week more intense and stressful than the week before, and that's exactly what happened.

Right off the bat, Alison Sweeney announced that contestants would have a chance throughout the week to earn immunity. They stuck a button in the middle of the gym. The first person to hit the button opened the scale. If they lost at least 2% of their total body weight, immunity was theirs. If they didn't, they were out of the hunt for that week.

Right away, the queen of gameplay, Melissa, was gunning for that button. With no allies in the house, she would need it to save her bacon should she fall below the yellow line. And then there was the challenge.
