The Purple Team is up next. Olivia goes from 228 to 224, for a loss of 4 pounds, while Hannah goes from 217 to 210, or a loss of 7. The group is now up to 33 pounds. The Aqua team is next to step on the scale. Courtney goes from 282 to 275, for a loss of 7 pounds, while Marci goes from 208 to 200, for a loss of 8. Ladies are kicking butt! Marci says that next week she'll be in "wonderland," which is code for the 100s. Also, Sami is in love with Courtney and her fantastic confidence. Courtney is in love with herself, but not in an annoying way, and says that she's lost 160 pounds on her weight loss journey. Good for her.

The Knowns have so far lost 48 pounds, with the Blue Team left to weigh in. Seems like a sure thing, but with Arthur you never know. But hooray! Arthur goes from 450 to 444, for a loss of 6 pounds, while Jesse goes from 266 to 257, for a loss of 9. That's 15 pounds total, and The Knowns have immunity with a combined 63 pounds.

While The Knowns are ecstatic about their immunity, The Unknowns look quite dour. It's time for their weigh-in. Challenge winners and immunity holders Justin and Rulon are up first. Justin goes from 308 to 292 for a loss of 16 pounds, while Rulon goes from 411 to 394 for a loss of 17. Holy shit. I guess it's amazing what people can accomplish when they have access to an elliptical machine. The Red Team is up next, and Q feels like he has something to prove. He goes from 398 to 385 for a loss of 13 pounds, while Larialmy goes from 270 to 259 for a loss of 11. Something: proven. I guess there was something to that burn theory of his. The Red Team has lost 24 pounds, or 3.59%. The Pink Team assumes that they are screwed.

Next up is the Brown Team. They need to have lost more than 24 pounds to be guaranteed safety. Austin goes from 342 to 326 for a loss of 16 pounds, while Ken goes from 335 to 321, for a loss of 14. These guys are putting up gigantic numbers. Maybe it's the strict Jennie-O and Extra Sugar Free Gum diet. The Brown Team has lost 30 pounds, or 4.43%. They're safe. The Gray Team is up next and needs to have lost more than 20 pounds to be guaranteed safety. They realize that this might be a tall order. Moses goes from 365 to 351, for a loss of 14 pounds, while Kaylee goes from 204 to 195 for a loss of 9 pounds. This is insane! They're, like, melting. Kaylee hasn't weighed in the hundreds for a long time, and is clearly very emotional to have reached that milestone. The Brown Team has lost 23 pounds, or 4.04%.
