Only Mearl, Joe, Bear, & John left in the main game.
Will, Dave, Derek, & Jake all on RI competing in the final duel.
However if none finish, there will unfortunately be no returnee..
If nobody enters the game, Bear's screwed.
If somebody does, Bear still has a playable idol.
Mearl is playing a great game as well as Bear.
The only way I see Joe or John winning is if there is a returnee, and the F3 is then 2 and the returnee.
However, very unlikely, because at this point all 4 people on RI would work with Bear and only Bear.
