I think it's Juliet Huddy, she was missing from last weekend's show, the photo of the weekend group now has Kiran and Juliet was really nasty to Kiran two weeks ago.
Juliet will be back this weekend, she was simply visiting her mother in Florida. I don't think that Fox would replace the more conservative Juliet with the more liberal Kiran. Fox has to keep a few conservatives on board, or else they'll end up like CNN.
