I apologize for not spoiling this season but I promise to get back on the ball for Survivor 17. Here are some spoilers for the finale.
The final 4 challenge is supposed to be standing on a pole and using something with water buckets. Its not certain who wins, likely Parvati or Amanda but its very likely Natalie is voted out.
Speculation is that the jury will vote on the final 2 this season and there will be a final 3 challenge. This will be the typical endurance challenge and again its not been determined if Amanda or Parvati wins but Cirie will be the one voted out.
Amanda and Parvati face the jury and Amanda will win with the help of Ozzie and James swaying the votes in her favor.
