I think our "missing" host Alex McLeod is lying on the cutting room floor, dieing the death of a thousand cuts. Which she deserves. I think FOX signed her on with good intentions, and is probably obligated by their contract to list her as host in the credits, but they are obviously trying to not show her. We may see her only where they just can't cut her out in post-production.
In her only appearance last night, one which would have been almost impossible to delete entirely from the show, she appeared bored, boring & over-dressed. I think they are adding in & emphasizing the butler post-production. He's funny! And a natural with the camera.
There were several times last night where the girls were talking to someone off-camera, and we heard the butler's voice but it had a different, studiolike quality, as though added later. Also, when he was talking to the girls just after he told them that 7 would be eliminated that night, it seemed to me as though the girls were reacting to him and to another person not shown (Alex?). This is one of the places where the butler's voice had a different quality to it when he was not visible. I am speculating that his voice was added later, perhaps saying lines where Alex's voice was deleted.
I think butler's 3 picks were Zora, Melissa and Allison. And the butler's a hoot! The show would not be nearly as good without him.
