I thought the exact same thing. The more he screamed to be pulled back up, the more she kept lowering him. I figured she was hoping he'd get stuck down there and she could continue the race with the guy they were rescuing instead.
Did anyone else gasp in disbelief when Kent told Vyxsin that he was always positive while racing. Seriously? He whined constantly. Not that she was terribly positive either, but she wasn't claiming to be Polly Positive either.
I will not miss them, and I'm glad their mistake saved Z/J, though I cannot for the life of me figure out why Z/J and G/M chose the obviously harder task on the mountain. Digging anything out of the snow is hard enough, but at altitude? That's way worse. Unless both members of a team were really claustrophobic, the other was a better choice.
And how come nobody played with the adorable St. Bernard at the pit stop?
