Ray and Deana arrive at the bookstore. And the books they're getting look exactly like the books Rob and Amber got. They, too, manage to get all 180 of their books onto the cart, but outside, they have trouble finding out how you get to the Library of Congress. ("Practice, practice, practice"? No, wait, that's something else.)

Here come Uchenna and Joyce and Lynn and Alex to the funicular. Brian and Greg, on the other hand, are stranded out on the streets on account of taxi problems. They note with some consternation that their driver doesn't appear to speak even a tiny shred of English, so they can't communicate with him at all. Megan and Heidi similarly believe that their driver doesn't know where he's going, as he doesn't seem to be driving with any particular sense of purpose.

Debbie and Bianca reach the top of the hill with Patrick and Susan, and they run into Gretchen and Meredith on their way down. Gretchen and Meredith want to leave immediately, of course, but it turns out that they still have to wait another four minutes for the funicular to head back down, giving the other two teams a reasonable shot at catching up.

Ray and Deana are trying to find the Library of Congress, and they're making the most efficient possible use of their time by arguing over whether it's worse that the writing on the map is really small or worse that the book cart is heavy. Once they figure that out, things will start to go a lot better, you can just tell. Don't tell me -- at the moment they're dating "off," right? That must be so handy, because if she gets offended at being talked to like she's stupid, he can just say, "Um, hello? We're not dating right now." And then later when he wants to make out? Well, you can immediately see the advantages.

Virgin Mary statue. Debbie and Bianca and Patrick and Susan get the Detour clue, and while the girls go with the books, Patrick and Mom head for the shopping. Because after all, they had to beg for money just to get on the funicular, so it seems like the most logical thing for them to embrace at this point is a task jam-packed with retail transactions. When Debbie and Bianca get to the funicular, Gretchen lets out a whiny, "Noooo!" about the fact that the ladies are going to get on with her and Meredith rather than being abandoned at the top. Patrick and Susan, however, don't quite make it back and are indeed abandoned at the top, so they have to wait. This is really going to put a wrinkle into Patrick's plan to foil Rob and Amber. But you just wait, because he's got them right where he wants them. They won't know where, they won't know when...well, unless they're looking backwards.
