Definitely animatronic spider.
Back at Camp No-Fun on Day 24, nobody is entirely happy but immune old Jamie. Speaking of whom, he and Steph have a chat in which Jamie reiterates that he wants to vote out Gary, because Gary is gunning for Jamie, as Gary "confessed" earlier. This is, like, the saddest thing ever. This is what you get for failing to enunciate, people. Steph, not really caring about who gets voted out between Gary and Bobby Jon, agrees. I think one of the things she's done right as queen of this little cabal is that she doesn't throw her weight around too much just for the hell of it. She isn't insisting on a particular boot order, and she's willing to let Jamie have his way, even though she's clearly fairly dubious about what he told her about Gary. She interviews that, actually, she was considering getting rid of Jamie, but the immunity situation obviously killed that possibility.
So now, Steph, Rafe, Judd, and Jamie all have a chat in which they agree that the Gary boot will go forward. Steph does express some concern that it's all seeming "too easy." I think that's what I'd be thinking, too. I've always said that a properly played season is really boring, because the way you play properly is to get a group together and then not have anything change, and that's pretty much what they've done. So she's doing it exactly right, and I'm about to doze off. Steph tells us that the Gary ouster makes sense both because Gary is a threat in challenges and because he's "always in game mode." Gary interviews that he knows it could be him tonight, and then we watch him go and talk to Steph. She fibs that it's Bobby Jon going, not Gary. But Gary tells us that he knows there's no way to know whether this is true or not. "That tells me that I need that idol," he says. And then...he goes off to look.
Bobby Jon takes maybe the one small strategic opening that's available to him by heading over to talk to Jamie and Judd. He tells them that the real threat to them is Steph, who will do whatever she needs to do to win. And whom, presumably, neither of them would want to face in an F2 situation. The problem with what Bobby Jon is doing is that I don't think he has a good argument about why, even assuming that's true, Judd and Jamie would be better off voting her out just yet. If these guys are in Steph's planned F4 in which she believes she can win -- and wouldn't you think you could beat those guys in a vote if you were Steph? -- then her efforts to win aren't actually a threat to them until that point. It's like...Bobby Jon has the right idea, but Steph has done too good a job positioning herself so that the people she's with believe that she wants the same thing they want. You can see how it's hard to break this alliance. Jamie and Judd respond by assuring Bobby Jon that he's not the one going home. Bobby Jon recounts all of this in an interview, talking about how he tried to warn them about Steph and her "million-dollar grin" (heh), and how Jamie and Judd said it's not him on the block. Which, of course, it currently isn't.
