Alicia's team heads to the platforms with rope bridges, and is nearly across before Rupert's team even gets to the first platform. Rob goes last for his team and dances across the rope. Was this challenge, which involved a great deal of balancing and agility, created for Rob's team to win? Who knows? All I know is that it was dumb to put Rupert and Big Tom on the same team. Shii Ann, Alicia, and Amber head down to their jail cell and start digging for the flag. Rupert and his team members make it across the rope bridge, and Jenna stays up top while the others start digging for the flag. Alicia's team finds the flag first, and Rob zips down the line to retrieve the key. He takes a leap off the platform, and swings his body in the air to gain momentum and make the trip as quickly as possible. He grabs the key, just as Rupert's team finds their flag. Jenna just kind of hops off the platform, so she doesn't go nearly as quickly down the line as Rob did. Rob gets his team unlocked while Jenna is still running back to rescue her team, and Alicia's team wins the reward. I really do love obstacle courses, but I think I like them better when it's two people going head-to-head. The team thing got a little confusing.

And now it's time for the immunity challenge. The four contestants (Alicia, Shii Ann, Amber, and Rob) stand in front of giant sliding puzzles, of the kind you used to do in grammar school where you had to slide the pieces around and get the numbers in the correct order or form a picture or whatever. In this case, they have to maneuver the largest piece of the puzzle, which contains a knife, into the bottom center of the board. ["We've seen this before." -- Wing Chun] This will allow them to slide that piece out, and use the knife to cut a rope, which will raise a flag. The first tribe member with his or her flag raised wins immunity, as well as time to drink hot chocolate and watch a video from home. They uncover their puzzles, and start mixing them up on Jeff's signal. It's not that exciting to watch, although the music makes it seem as though it is. Shii Ann, who is supposed to be so great at puzzles, sneers when Probst says that Rob is close to being finished. Rob does, in fact, finish first, and he urges his flag to go up faster, which I found kind of amusing. He finishes by stabbing the knife into the table, much like he has stabbed so many people in the back, which I also find amusing. Probst adds that he's not sure anyone wants to see the video of Rob's brother, and Rob cheers. Shii Ann looks pissed, because she has been outed as completely useless at every possible task. Amber and Alicia hug Rob, and Kathy does a slow clap.
