I'm not really buying that Alex could be the mole. I have no clue who the mole is, but I have some good ideas on who the mole isn't. I obviously could be wrong, but the guy with the blue fire tattoo (Paul?) is NOT the mole in my opinion. I don't think Bobby is the mole either because he has not been subtle at all in sabotaging challenges. You're really supposed to have to look to find someone screwing up. He's been blatant in almost every challenge. And I don't want to think that history teacher guy is the mole after his little breakdown in episode 1 about his wife. It would be pretty dumb if he was the mole after that.
I personally think since the group has been doing so poorly in challenges, the mole probably isn't going to sabotage much, the other players are already doing a great job. So why expose yourself when other people are doing the mole's job of keeping the pot low?
coolarmydudeAlso, the ransom letter was signed el topo (the mole); therefore, the mole is male. If the mole were female, it would have been signed la topa.
At first I thought that was very clever that you caught the el topo/ la topa thing. But I ran topa through a translator, and it doesn't mean mole. Topa in the places I checked it meant "runs into" or "it runs into."
The mole could still very much be a man, but I don't think it HAS to be a man because of that clue. Personally, I think any of the women could be the mole except for Nicole.
