that could be the dreamteamer shot we'll see when Jiffy explains the challenge ...
I wish I could see the fingernails better. Any Survivor should have long dirty nails. They look clean and shortish to me.
And yes, the writing is WAY neat for during competition.

JP says that BRILLIANCE wins.
I suppose it could be cooperative. I don't think there's any rule against helping each other.

In fact, I dimly remember a long ago challenge where someone gave a puzzle hint to another player, someone who clearly wasn't going to win, and didn't want the other person in line to win it to get it. I can't remember what season though.

I wonder though if Stephen feels secure enough to help JT win. It's always dangerous to give up a shot at immunity, and I'm not sure he would, Nash or no Nash. That is a good guess for the book though. I've read Burnett's book a couple times and I don't know what it would be that helps, plus you don't need to be a brainiac to get through it, only a fan.
