Ok, I have to start by saying I usually can never find the clues, but last night something jumped out at me as a clue. However, I must preface by saying I am a die-hard bribsfomo, I definately think it's him.
What I thought was suspicious was near the very end of the episode, when Al was talking about that he has felt like he was being played because it seemed the Bribs and Darwin were so chummy and maybe had an alliance, then he said since Darwin hit the bricks "maybe he was the one being played after all"...who would be playing Darwin?? The mole, which is Bribs. After all, if Bribs is the mole, even if he cared about Darwin, he would have to lead him toward someone else, as he is not allowed to give himself away. Does anyone else think this is weird, or have I been watching too closely?
Btw, I also noticed it was funny that Bribs said he thought it strange Al did not go for the mechanical game, as he was good at mechanics. But Al never knew there was another game, as soon as AC mentioned there was a liquor game, he was out the door.

Also, it seems to me the code has def been cracked as far as the order of the players leaving. So the question is: its down to Al, Heather, and Bribs. Any bets on who wins?? Thats a tough one for me, cause every clip of Al looks like he's clueless, and I think he's too loud and stupid to be the mole, Heather-how can she win if she had a coalition w/katie ..who I thought they were after Bill as the mole???And from day1, I thought she couldn't be the mole cuz she reminds me too much of Kathryn. They want to have someone at least a little different. Wouldn't they? And Bribs, he seems smarter than everyone else, but also seems unbelievably moley to me. As well as that clue in the crack code about him being the mole.
