Eliza and Jason will be running the course for Airai, leaving Natalie and James to throw sandbags. Amanda and Erik will be running the course for Airai, leaving the Crab Warriors to swing the bags. Jason and Erik go first, and we see that the obstacle course only has one balance beam. So if one person is on it, the other player has to wait until he gets all the way across before he can go. This is stupid. I'm guessing/hoping this was a last-minute way to play catch-up with all the unexpected player losses and they just didn't have time to build two balance beams. It's either that, or the brains behind the challenge that almost killed Jonathan have worked their magic once again. The race starts, and while Jason walks across the rope bridge, Erik chooses to jump across it. He makes it, although not very gracefully, and gets to the spinning balance beam section before Jason, so Jason has to stand around waiting for Erik to get across. Despite this, they're just about neck-and-neck as they roll through a net to grab their flags. They make their back to the beginning, with Erik nearly falling through the rope bridge, then managing to stop himself by swinging his legs out and grabbing both ropes without touching the ground. Meanwhile, Amanda probably got a faceful of penis. Jason catches up and Eliza sets out, but quickly falls through the rope bridge. Just as she's turning to go back, Amanda comes flying through the frame as she also falls. She did not look pleased about that fall one bit. It probably hurt. Jason gets across first and Erik catches up to him with another leap across the bridge. They both get their flags back to the beginning, with Airai in the lead. Eliza makes it across the rope bridge this time, as does Amanda, although she almost falls through again. While Amanda slowly gets across the bridge, Eliza is knocked off the balance beam by Ami's well-placed sandbag. By the time Amanda gets to the balance beam, Jason's right behind her. They get to the rope bridge, and Jason makes up for lost time and takes the lead.
