I'm going to go back to past seasons and pinpoint the moment when Heidi learned the idiom "throw under the bus." It seems to correlate directly with her swift mental disintegration in the last couple of seasons. That said, bravado coming out on those stilts. I usually hate the partner exercises, but this one was fairly good.
Also: Eeeeeeeeeeeeeeeeeeeeee, next week is gonna be gooooood!
