Who is responsible for you being voted off?
Mike Skupin. He lied through his teeth to me. He was a puppy dog through the entire game, really wishy-washy. And he said he was on my side, but he really wasn't. So I blame him.
I think Penner's tribe would not be happy with him for voting with Tandang (and his ally Skupin), and voting off one of their own (Jeff), so he voted with his tribe, but made sure his vote resulted in the ousting of his nemesis, Jeff.

Somehow I'm not surprised Jeff is still bitter.
