I have a feeling that Tracey Gold is the mole. One, she went with the correct answer in the "whose lying" game, then switched her decision because everyone was going for the other one. Two, she didn't go and help Keshia when she felt "sick". I may be wrong
Well, whoever the mole is, he/she has not done a good job screwing up the game cause they already have $30,000. Thats too much money for the first day.
If I was playing the game, I would make it seem like I was the mole, even if i was not, so that everyone would concentrate on me and fill out their quizzes based on what I have done. Surely, their scores would me lower than mine
