(S09E05) This was the week the Blue and Yellow teams have been waiting for. After four weeks at home, working out without their trainers, both teams were back on campus to see which would be allowed the chance to return to the show. It came down to which pair had the highest percentage of weight loss.

But before they got on the scales, Bob and Jillian treated them to their first -- and for one of them, their last -- "Last Chance Workout." I couldn't help but feel for the team that was going to be heading home again. Twice they'd come to the Ranch to participate in 'The Biggest Loser,' and twice they'd come up short. At least they still had the chance at that "At Home" prize.

This week also saw Alison handing out immunities like they were going out of style, as well as a two-pound penalty to the team to finish the week's challenge last. I'm a huge proponent of this element being added, as it keeps the incentive on the contestants to give it their all until the finish.
