To answer your question: I think he is just fine, but wishes he could have stayed on longer (obviously). I'll know more when I talk to him.
Did he really like Erin or just a little upset that he did not get enough air time?
BTW, on NBC site there is a poll on which of the five eliminations was the most surprising. Chris scores 52% so far. I am still in shock after Erin took Much over Chris.
