During Bobby's execution he thought Paul was the mole b/c of the Apple thing. . .he was eliminated. Its safe to say that he answered Paul during his questions.
During Kristen's execution episode (in the missed clips episode) we saw Kristen suspected Clay and she was executed. Even in her confessionals she was saying she's going with her choice.
If we eliminate Bobby's guess and Kristen's guesses as Moles we are left with Nicole - Mark - Craig.
Last night's episode Alex was accusing Nicole of being the mole and even wrote it down in his journal so either A.) He missed the most questions about Nicole since only 4 people were competiting on the test or B.) He put Nicole all the way through and he was wrong.
Mark had a great chance of sabatouging the mission the other night. A.) He didn't have to help with the questions B.) He didn't have to stay on the treadmill so long. We can pretty much rule Mark out.
The Mole is probably: Craig
With a possibility of: Nicole
Slim Chance: Mark
