Heist planning notebook
While the notes are a bit juvenile, it looks like they contain a plan to lift an immunity idol from a future challenge. You just have to put some tape on your nose, then while participating in the upcoming Train Brawl challenge, find time to sneak off and post in your confessional once during each round of the battle. During the first round, you have to break into where the idol is located. Post "BREAK IN" into your submission thread. You need to do this before the round ends, or it'll be too late. During the second round, you'll need to grab the goods. Type "GRAB IDOL" in your confessional during round 2. Finally, during round three you need to get away with the goods. Type "ESCAPE" into your confessional during round 3.
Team Zissou rings
First off, you're going to want to put one of these bad boys on immediately. Team Zissou! Okay, now, at the time of your choosing, you may offer the other ring to any other player. Just post in your confessional when you decide to give it to someone. They'll need to post that they're accepting the ring in theirs. Then you're both members of Team Zissou, which means you cannot vote for one another. This will be true up through and including the final five.
