We are heading into Week 4 on The Biggest Loser 2013 tonight and out of the three weigh-ins this season, only one of the trainers (Jillian Michaels, Dolvett Quince and Bob Harper) has their Trainer Save left to use, but will Bob be forced to use it tonight? I think the save has come into play many times on different shows, but it is a tough one to use on The Biggest Loser Season 15. Why? Because no one wants to see these contestants go home so early, especially when they have been kicking butt at the gym. We get another weigh-in tonight on Biggest Loser 2013, so who goes home tonight? Check out our thoughts in our Biggest Loser 2013 spoilers that follow!
