Okay, so Fox really screwed up by allowing the old guests to watch everything peolple said, and THEN come back to the show, which is totally insane.
So why would the next guests of PH say ANYTHING that could get them in trouble? I would think they would have zero incentive to make "confessionals" to the camera or strategize with other gusts in front of the cameras. So what you end up with is a bunch of people manuipulating each other all the time, and only talking out of camera range.
If I was on the next show, you would not catch me sayoing a single negative thing about anyone else. The only way I would be is if I was in the pool with my mike off, which would make for very boring reality TV.
