Scrappy you're absolutely right, but there's no need for spoiler alerts, because I pointed that out a week ago :)
BTW .. I also think that they had some off camera help. they had absolutely no clue till the episode 9. The show has to have 10 episodes with "happy" ending. I honestly cannot imagine how can be someone so stupid like these people. The have a big chance of winning 1mil dollars and they're not strategizing, writing down previous matchups, making charts.. nothing. They're just yelling at each other, fuck and drink booze. What a douchebags.. but I also understand that season full of nerds would be extremely boring. So maybe that is the intention.. like pick 20 people who are stupid enough for the show.
All in all.. I have to admit I like the show and it's concept. But I think it can be much better than it actually is (maybe especially because of who mostly watch MTV).
