On previous Mole series they always show on the last night some not-so obvious clues that were given all along. One time it was the mole's initials on a helicopter in the background, another time they showed the mole's bag with her name on it in the opening, etc. Well, last night during the introduction, they said "Who is the Mole" and for a second they flashed on Keshia, and nobody else. This made me think that it could possibly be her, and that that was one of their secret clues.
This is, of course, purely a guess on my part. If you ask me, Dennis Rodman is too stupid to be the mole, so he could very well be it too. Stephen and Corbin would be too obvious, but maybe that's what they want you to think, so one of them might really be the mole as well.
All I know for sure is, Angie Everheart irritates the heck out of me!
