Thanks, Sheldor! Looks like they're not giving us much to go on here, with so much old footage. Two interesting tidbits that stood out to me:

1) Chrissy is wearing the expired super immunity idol. Assuming it's new (she looks too dirty for it to be the first TC), this seems to imply she has not won a key immunity and is trying to ward off being a target. I wish she would use it to try to trick Ben into finding/using it, because that would be more interesting. But then why would she be wearing it? Here's Jeff from a preseason interview with Jeff Wigler on this topic. This seems to imply that Chrissy uses it strategically as a bluff.

"It's a super idol, which means, you're in charge. You're in charge of tonight's Tribal and you're the only person who knows it. You can play it for somebody, or you can watch somebody go home. You can play it for yourself. Or you can not play it, keep it, and only you and the sender will know that it has no power, and it looks so cool, that maybe you can get some power by bluffing people. I'm really excited by who found it and I love that it's in their hands. I think we're going to have a great story. We'll see what happens at the immunity challenge.

2) The final secret advantage. What could it be? Hope it's not eliminating a jury vote -- I hated that. Could be a challenge advantage. I also recall reading something preseason about the F4 winner getting to pick who to bring to the finals and then the other two having to do a fire challenge. Was that just a rumor? I'm going to try to dig that up again. Other thoughts?
