Natalie manages to tear herself away from Ashley and talk to Rob, who is swinging on a cool rope swing-chair-hammock thing I've never seen before in the camp. She says it's going to be hard for her to be a part of any plotting against Ashley, since Ashley is always near her. Rob says if he'll just tell Natalie what's going on right before Tribal Council if she can't get away from Ashley after the challenge, and that no matter what happens, he has her back. Rob then masterfully makes Ashley look like the bad person here, saying that he knows it will be hard for Natalie to vote Ashley out, but he thinks it has to happen now because he just can't stand to see what Ashley is doing to Natalie. What, being her friend? Trusting her way too much? Please. He doesn't get a chance to say much more, though, as Ashley walks up and he quickly changes the subject to peanut butter recipes. Rob interviews that Natalie is stupid, but she's "sweet" and "pure" and Evil Ashley is trying to "corrupt" her. He says that Natalie and Ashley's bond was never about strategy until recently. Therefore, he's really looking forward to getting rid of Ashley, who he says is a pain in his ass.
The Final Five arrive at the immunity challenge. Probst describes it: each contestant will piece together a series "fishing hooks" (a.k.a. giant S-shaped metal hooks) and use them to pick up three bags full of puzzle pieces they must assemble to create a giant fish skeleton. And they'll have one hand tied behind their backs. Not only does the winner get immunity, but he also gets a reward of a three course meal delivered to camp so he can eat it in front of everyone else. With that, we begin. Grant gets an early lead with the first bag, but the rest of the contestants are pretty close behind. They get their first bags on the skeleton mat and find a way to untie the knot with just one hand before placing their puzzle pieces, which are basically ribs, on the skeleton. There doesn't appear to be any set order for where to place the ribs; it looks like any piece will fit into any slot as long as it's placed correctly and it doesn't touch any of the other rib pieces once it's in.
