The Detour was Magellan-related as he's important to the history of the area. The teams could either Detour It or Sign It. In Detour It, teams had to navigate the city by map and compass to find the Nautilus Building where they would receive the next clue. In Sign It teams had to erect a signpost with all of Magellan's stops. The cities didn't have to point the right direction, but all must be spelled right.

That was the beginning of the end for a fan favorite team or one that folks loved to hate. Either way, a team who made this race more interesting started what would do them in at the end by choosing the wrong task. The teams who chose Navigate It seemed to sail through while the teams choosing Sign It fell further and further behind.

While Uchenna and Joyce, Rob and Amber, and later Charla and Mirna, struggled with the sign task, the ChaChas, Eric and Danielle, and Teri and Ian made it to the next point in the race. They snagged the first charter plane of three leaving three hours apart on their way to Playa Larga in Ushuiai, Argentina. Amber tried to convince Rob to go to the other task, but he was determined. Finally, Romber teamed up with the Beauty Queens (Dustin and Kandice) to do Navigate It. Even Charla and Mirna switched to that after horribly trailing the other teams.

I have to mention how nasty Mirna's treatment of Charla was tonight. That woman is condescending, mean, evil and outright mean to her very own cousin. She creeps me out. I so want her gone.

But, back to the race at hand — Rob, continuing his streak of bad decisions, led the BQ to the wrong building, thus increasing the lead the other teams had on them. As one of the Beauty Queens later said, "Rob and Amber weren't very helpful." Amber teased Rob to admit he was upset because he wanted to come in first again. Rob sheepishly turned to the camera in the cab, "I want to be in first." Aw. They later lied to Charla and Mirna and had all the other teams laughing about it. Alas, the cousins caught up.

After the charter flight, teams had to take boats which left every 20 minutes to the Isle of Redonda or, as it's known, the end of the world. It's a longitudinal thing. After they got to that point, they faced a Roadblock at the local post office. One member of each team had to search through a huge bag of letters for one addressed to their team. The letters were from a team which had raced the race with them in their own seasons.
