I have to respectfully disagree with the Tarzan naysayers. He is a very smart man, acting like he's a nut. Notice that his "dementia" seems to have disappeared? I guess it's a different kind of social game. I never did see the first season, but didn't Hatch disarm by walking naked on the beach? Naked, poopy pants, etc. ...it's all the same. I just do think it's all part of his game. If you listen to some of his quieter comments ... he is also pretty "wise". Not a shallow person.
Oh and who is going to F2/3? I think it might be Sabrina, Alicia and Tarzan.
