They and the other teams head over to the wall, but there all pretty clueless, starting with how they can't find the decoder key. Thomas, ever the charmer, starts ransacking kids' homework and dropping books on the ground. Dude, that's not cool. I'm starting to see a pattern of him thinking the world is like a game show set that he's running through, not a place where actual people live actual lives. "Just keep your eyes peeled," he says while the Amazing Editors show us a nice shot of the decoder key COVERING AN ENTIRE END OF THE BUILDING. Katie and Rachel are the first to decide to bail on this and head for the soccer field, making them the second-most successful team at this Detour so far.

Michael and Kevin arrive at an indoor classroom, and Michael looks pretty glad of the chance to sit down, which is a worrying sight at this point in the leg. Unfortunately it wont be a long rest, because Kevin identifies Ghana on the first try. They have their clue in seventh place, and Kevin says they're doing Language Arts. Good choice; that seems marginally less likely to kill Michael.

Gary finishes rolling his hoop, while Mallory clanks along behind him. She finishes while Katie and Rachel are still working on learning the proper way to do it. Gary and Mallory's subtitle reads "Currently in 2nd place" as Mallory reads that they need to make their way on foot to the next Pit Stop. I still don't understand how they jumped ahead so many places, but off they go.

Nat and Kat are pushing their wheelbarrows, saying they're not giving up, which is the kind of thing people say when they know they're in last place. They get their clue from the foreman, which Kat reads while Nat dumps her water bottle over her face. Did you know that when they're at school, anesthesiology trainees practice putting each other under so they know what it's like? I think Nat's missing a valuable chance to know what it's like to experience passing out from heat exhaustion

Back at the puzzle, Brook thinks they've found the right sequence, but since they have it going from right to left, it's wrong. "I hate puzzles," she says. Michael and Kevin have arrived now, while Chad complains, "This is the dumbest freaking crap ever." Even dumber than the dumbest freaking crap ever from two legs ago? "We have no clue." Stephanie suggests switching, and Chad agrees.

Nick and Vicki are in an outdoor classroom where they have to label Ghana on a map that has just about every country already labeled save Mali, Côte d'Ivoire, and of course Ghana, and Vicki still gets it wrong. "No, please," one kid yells out helpfully. Thus begins another montage of Nick and Vicki failing while interviewing about how stupid they are until Vicki finally gets it, more from process of elimination than anything else. Nick decides they'll be doing bicycle parts, I assume because their cognitive resources have already been tested to the limit today.
