I think he did what he needed to do to advance. He came right out and said that he never felt comfortable with his own tribe, but felt an instant connection to Steph, Jamie, etc. And I liked the way he didn't try to bs Margaret, but told her that he would think about what she had said to him. Well, he DID think about it and went with the people who made him feel more comfortable. Nothing wrong with that. I think he'll make it to the final 6 or 7 [maybe further, who knows?]
At any rate, I'll bet he never lives it down over the howler monkey. His friends will probably rag him about that FOREVER!!
