Maybe we have a simple clue that has been right under our noses from almost the very beginning.From Priscilla and Fleet's peculiar actions and mutterings, especially while at the funeral in Atlanta, it is obvious they have a disdain for "fatcats".

Their actions over time have only reenforced the need for looking at these people, seriously.
