When we return to Santiago, Susan and Patrick are begging for some money from an American, and it appears that they do give him some U.S. dollars in return, so they're not purely begging. And that, I appreciate. On the funicular, Meredith and Gretchen are fretting about the possibility that Susan and Patrick indeed ran out of money. Meanwhile, mother and son do indeed get their funicular ticket at last, but...they learn that it will be ten minutes till the next car.

Bookstore. Rob asks whether they can take 180 of any books they want, and the guy says yes, they can take any books. Outside, they work with the hand cart that will be the form of transportation for this task, and Rob explains that working in construction, he knows how to build stacks so that they'll be stable, which I suspect is true. Nothing against academia, but I do think that a background in something like construction would be more helpful on this show than, say, a degree in philosophy. (Watch -- I'll say that, and then the next Detour will be Carts or Descartes.) Ron and Kelly are right behind Rob and Amber, but when they have a little over 100 on their cart, Ron tells Kelly that he thinks they should take off and do it in two trips. Rob, however, keeps stacking. Kelly mildly objects to the two-trip idea, but they do indeed leave without the full complement of books.

Debbie and Bianca come to the funicular and find Susan and Patrick, surprised to find anyone from the other flight still there. There is hugging. They get on the funicular and head up. At the top, Gretchen and Meredith are getting the clue, and on the theory that 180 books is "a lot of weight," they decide to do the shopping. I'm really not sure in this case that the books are that physically demanding, given the cart. You don't have to carry them on your back or anything.

Elsewhere, Rob and Amber finish piling all 180 books on their cart. And you'll note that they have four columns of books on that cart, so it's something like 45 books high, which isn't that overwhelming. They wheel their cart out. And as they and Ron and Kelly wheel their respective books through the streets, you can see that Rob stacked those books into a tight, unmoving wall with sections that point in different directions, like you would with bricks. He's so very often full of shit, but he wasn't full of shit about that, I don't think. Ron and Kelly's books fall over at one point, and there is an awesome pan directly up from them trying to get their books back onto the cart over to...Rob and Amber, scurrying by with no trouble. Great shot -- tip that camera guy, and the editors who undoubtedly reframed that until you couldn't see the other camera guys who inevitably must be nearby.
