Wow, that was a great episode!
I always enjoy watching the psychology of the game. Brett and co. were awfully cavalier about putting John up as a shield. I knew John would switch at the second vote--why wouldn't he? They told him where he stood. I was also glad that FFF (the Foa-Foa-Four) didn't make a deal with Monica--she needs to go.
The hunt for the immunity idol was a hoot and a half. I think Russell is just really clever--he saw the rock on the video, and accurately described it to Jaison--size, color--so I dont' think he got help form the production crew. He also had a good idea as to what part of camp it was in, based on the video. SO, jsut smart thining, IMO.
