Ready...go! Okay, the first thing you need to know is that Katie is never in it, ever. Even for a second. She's the baseball team in every league that shows up late for the first game with only six players, looks around like, "What?," and drinks beer for the rest of the season. A-Jenn, however, stays pretty well with Tom and Ian out of the gate, much to everyone's surprise. All three of them are in it through the tires, through the locks, through the ropes, and up to the part of the tower with the grappling hook. Tom is the first to get there. He gets his first rung. Ian and A-Jenn are even, and Ian gets to the grappling hooks only very slightly ahead of her. Ian gets one hooked. A-Jenn, on the other hand, can't figure out how to use the hook. Tom gets his second rung, and then his third. Ian gets his second. Tom pulls in his last one and assembles his ladder. A-Jenn is in the weeds. Ian gets his third rung. Tom climbs to the top and raises his flag. Ian gets his last one, assembles his ladder, and climbs to the top. So the final will be Tom and Ian. Katie -- having gone backwards in time and actually retied knots and locked padlocks that had been untied and unlocked when the challenge started -- will not be in the final. Neither will A-Jenn, because when you ask her to throw a hook, she just isn't sure what that means.
And now, round two. Tom and Ian take off and fly down the wire. They hit the water at the same time, and they hit the box at the same time to get the bag of numbers. It is on the run out of the water that Tom begins to pull ahead, on what appears to be brute strength. But then Tom stalls out trying to get the bag of numbers open, and Ian passes him. Ian is, in fact, the first to get the bag open and get the numbers out. But in the end, there is a huge element of luck here, and Ian simply doesn't get the combination quickly enough. Tom is first to get the lock open. He opens the box, grabs the flag, runs it up the pole, and takes home immunity -- again. Ian grins, and they hug. Nice, isn't it? It can't last. You know this. Somebody will get snitty because of all that money, because somebody always does. Not always the one who thinks he's doing it, either. Anyway, Jeff puts the necklace around Tom's neck and reminds us that Tom is the only safe one. Everybody else is on the hook. Now go back to camp, doofuses.
At Koror, the tribe is pulling up to shore as they discuss how enormous the challenge was and how long it took. Ian interviews that if he won, he was planning on sending Tom home. But he didn't, so now it's got to be A-Jenn.
