From what I'm reading on other blogs and message boards, most fans would be happy if the producers said, "Good riddance!" to the remaining group, most of which have shown a talent for bullying and backstabbing. You've got to wonder if Joe saw the writing on the wall and that's why he packed up and went home rather than go through the treatment they've given other players.
I wonder if they walked out because they didn't want to face the people that they treated so poorly during the season. Roy! Nancy! Lauren! You were class acts. Bringing some of you back might actually save this season.
The "secret plot twist" wouldn't really be so unusual. There have been past seasons where eliminated contestants were able to come back. Last season, Ramon was eliminated but because he won the marathon, he was in the finals.
The next "Biggest Loser" episode, airing Feb. 28, finds the players returning home for 18 days with a challenge to lose 5 percent of their body weight.
