Speaking of the dev...I mean Amy, her tearful "confession" to Jillian that Neil "pressured" her into "watering-up" for last week's weigh-in makes no sense to me. They weren't even in the same group. And, have never been on the same team. With Isabeau his intended target, Neil caused their group to lose the weigh-in by "watering-up" first. So, I doubt that he cared how Amy's, or anyone else's group fared, as long as they all beat his.
And, what did Neil have to do with Amy, and the rest of her team, "watering-up" for their fourth weigh-in? The week they "earned" immunity. But, did they know about their immunity soon enough to "water-up" first, knowing the results wouldn't count against them? Or, were they intentionally trying to "throw" the weigh-in. If so, I'll bet Amy was the ring-leader.
Anyway, if Neil did pressure Amy into "watering-up" last week, her giving in suggests why she's so fat. Blaming others, and excusing herself, for her over-eating.
