Everything you said sounds right. It has to be that way to keep control over the outcome.

Also, for the record (and I'm not being a wiseguy here) A THEORY you have, or something you think MIGHT happen, is NOT considered a "spoiler"
A spoiler would be....well, a SPOILER! LOL
Information that would spoil it for the rest of us that aren't privy to the info you have.

If I say "I THINK Hutch will be kicked off next because..."
That's NOT a spoiler

If I say "Here's what's going to happen in the last episode. The secret will be revaealed to Matt, he gets REALLY angry at first, but is relieved when he finds out that he's not only the winner of the fake show, but he's in fact won FIVE hundred thousand dollars..."

THAT would be a spoiler. Anything that I state as FACT. Like inside source type stuff. ;)

I just wanted to save you time from having to use all that filler before making your post.
