Diane Henry explained her process into BB and said BB producers showed up unannounced at her house and swept her off. At least that's what I think she said... it was a year ago. She said several contestants were placed in a van and left in say a parking lot with no air-conditioner, no nothing. Hot, uncomfortable with say 10 strangers. They had no idea why they were left to sit together. The assumption after the show was over was they were like laboratory rats being watched by producers. The final cut was made through this process.
