It's amazing how some of these contestants have matured/grown up/had revelations since the last time they'd been on TV. John is one of them, but Rachel, wow. She's not that annoying. And helping Margie and Luke through the challenge. I'd like to think that Rachel's act of kindness helped her and Brendan in getting the non-elimination pass.
Interesting challenges with this ep. The bamboo trampoline and the pouring the drinks challenges were original.
