"Heather KNEW there would be an exemption. she said so.
>WHY did she leave the game? What I mean is, wouldn't she
assume that the exemption came by being more active in the game, rather than leaving?"
I agree w/ your point. During the "Grease Your Gnome" game, she also stated an exemption would be inside the gnome. Plus, after complaining early on about NOT getting offered an exemption, she turned down her opportunity in the "prison cell" game to earn one.
"Darwin let dorothy take his turn... OR DID HE?
I think we'd all have to agree that Dorothy is either extremely smart or the mole. As such, would she really hit the ball out of turn ON ACCIDENT?"
I think this is a very valid observation. If Darwin had not been eliminated, his move would have been highly suspicious. But because he WAS eliminated, perhaps he thought he knew who the Mole was, and therefore tried to simply sabotage the game to throw suspicion his way. But...more interesting is your point that Dorothy would have KNOWN than Darwin had not taken his turn.
Notice how Dorothy manages to blow every, single "physical" game. She can handle the mental gymnastics, but "oh my heck" she can't even manage to swing a ball in proper sequence!
If she is the Mole...why would the producers make her so lame in all physical aspects?
Of course, on the other hand...other players are inept in BOTH physical and mental challenges...(Does BILL come to mind?)
So what do I know?
