The teams make their way to the challenge and meet up with Jeff at what appears to be a big obstacle course. He asks the women how they're doing, and they say they've spent "two long, cold, wet nights" at camp without fire. The guys add that they need fire before they can have water, so that's their priority. Jeff explains that indeed, the challenge is in the form of an obstacle course that the team will do in one big group. It starts with a belly crawl in the mud, and then three team members will operate a box maze and drop a ball into a net at the end. Once the maze is done, they'll all have to get across a balance beam, and then run and build a fire in a kettle. When the fire burns through the rope stretched above the kettle, a torch drops. You light the torch and then light one last fire, and you're done. The reward segment is that if you win, you get flint, which can be used with your machete to make fire, at least in theory. In addition, you'll take the pointy-headed immunity idol. Which is...really, really pointy-headed.

The teams get to the starting lines and wait. Survivors ready...go! It's basically a draw through the mud crawl, although the women have to drag Scout out at the end, which I think is probably in part because of her knee, which may not bend sideways in quite that way. The teams operate the box maze, and the men finish it first. They move on to the balance beam. Chad falls off, as Jeff encourages the women to keep working, because they might catch up. Travis (whom Jeff is calling "Bubba," like, thanks, Jeff, I'm not confused enough yet) falls off. One of the Johns (K, I think) crosses successfully, just as the women finish the maze. Brady crosses. Travis crawls for it on his belly, scraping himself along the beam. Ow. Some of the women are doing the same. In fact, most of them are. Leann is across. Travis is across. Chad is across. Lea is across, Dolly is across, Mia is across, Rory is across. It eventually comes down to Scout and Chris. She digs, crawling across and grimacing, and Chris does likewise. Chris is really, really almost there when he tips to the side and rolls off, landing in the net. The men curse him under their breath as Scout continues to crawl. She apparently loses her top as she gets to the end, because she's all blurred as she rolls into the net. Wow, who knew the first pixelized chest would be hers? The women pull her to the mat so that they can start their fire, as Chris tries to run across to make up the time he lost. He falls off. The women start to build their fire. Chris falls off. The women build the fire. Chris falls off. The fire catches. Chris falls off. The fire burns. Chris falls off. The rope catches fire. The rope snaps. Chris falls off. The women grab the torch and run to the mat. The women win the first challenge. They try to get a chant up, but they're really not very impressive. They definitely need to work on their hooting and hollering. Jeff gives the women their flint, congratulates them, and sends them off. He tells the men that they'll have to show up this evening for tribal council. The women celebrate.
