Getting from Istanbul to the next destination of Moscow proves tricky enough for the racers that the six remaining teams end up on three different flights. James & Abba and the Chippendales arrive in Russia's capital in the middle of the night, while Trey & Lexi and the twins show up early in the morning. They're all in time to enter a sculpture park at opening time, where they collect a clue for the Detour.

In the "Alphabetized" option, they have to dive into the massive card catalog of the Russian State Library, Cyrillic alphabet and all. Trey and Lexi manage to complete this out of luck and sheer determination and end up with a lead that they hold onto all the way to the Pit Stop. Meanwhile, Jaymes & James and Natalie and Nadiya do the "Synchronized" option, in which they have to temporarily join the Russian synchronized swim team. Both those teams struggle a bit, and the twins even consider using their Express Pass, but eventually they make it out of there and on to the Roadblock at the Trees of Love. There, Trey, James, and Natalie have to painstakingly disengage a ribbon containing their next clue from a tree of padlocks, using a provided key ring. They all eventually finish and make it to this week's Pit Stop, the Bolshoi Theater, in that order.

James and Abba have a tougher time, however. After bailing on the library task, the swimming task proves no easier, and they have to make a number of attempts that they claim is in the double digits before earning their clue. And when they finally make it to the Roadblock, their cabdriver leaves without them. But with their stuff. At this point, all Team Metal can think to do is finish the Roadblock and proceed to the Pit Stop with the clothes on their backs and the cash in their pockets, at which point Phil tells them they can't check in without their passports. Which they do not have.

But I've only told you about four teams and there's six left, right? Well, that's because Abbie & Ryan and Brent & Josh decided, way back in Istanbul, to roll the dice (or in the goat farmers' case, flip a coin) on a one-hour layover in Frankfurt to try to get an earlier arrival time in Moscow. Needless to say they miss that connection, and there are no flights out until the next day. But in the course of a long night in the Frankfurt airport and a subsequent connection through Warsaw, they form an unlikely alliance in which they agree to run the leg together, even though (or perhaps because) there's no way they aren't going to be last. Indeed, Trey & Lexi have completely finished the leg before these two teams even get to Moscow. And when they do, the library is closed, meaning the synchronized swimming Detour is their only option. Abbie & Ryan kill it, while it turns out Brent can barely swim at all. But they're still sticking together. And Team Metal still doesn't have their passport. So how else can this episode end but with the dreaded, "To Be Continued"?
