I agree with the above poster. As a Mark-FOMO supporter, I'm really hoping that they'll show us things that none of us could possibly have caught onto, and if he's the Mole, I have a feeling that he got into some difficult situations in which sabotage would be difficult without giving himself away (and example being the treadmill position in that wine mission. I think that Craig and Nicole were testing him to see if he would pipe up with the obvious answers or not).
