I manipulated the above images a bit more to make things clearer.
This is the green thing I'm trying to figure out...
And what is the green thing in Brendon's fanny pack? A green FF clue - but is it from this leg or the previous leg that had a FF?
The previous FF was in Azerbaijan (leg 6), and Davechel won it. So this should be the FF clue of this leg. According to this, they must go to the place of the first task of the race, so this info and the FF info are in the same clue envelope. And this is from the moment when Rachel talks about the extensions of U$S 500. I guess Brendon, after made the decission of not to perfom the FF, is about to read where they had to go and what they had to do there.
And about Davechel, I had no idea. Maybe something the High Priest gave them after the Detour?
