The episode's true emotional gut punch comes through a montage set to U2's "With Or Without You," when following a tense Amtrak checkpoint, Elizabeth and Philip look out the window of the moving train and see Paige, who's leaving them behind to stay in America. Unable to react without drawing attention to themselves, the devastated parents have to swallow the growing realization that they're likely never going to see their children again. On a plane ride, Elizabeth has a dream - featuring Derek Luke as the long departed Gregory - where she's disturbed by images of her children, who have meant far more to her than she ever thought they could.

Not long after Stan's confrontation with the Jennings, the FBI puts together the pieces on their own and begin searching for the pair. Stan knows they'll never catch them; they're too good at what they do and have too much of a head start. Stan visits Henry and tells him about his parents, seemingly cementing his status as the only family the distraught boy has left. Amid the chaos of the investigation, Stan also can't help but look at Renee in a new, suspicious way, one last bit of mistrust gifted to him by Philip.

Improbably, Philip and Elizabeth make it all the way back to Russia, where they're met by Arkady Ivanovich Zotov (Lev Gorn), who was head of the Soviet embassy in America for much of the show's run, and a pro-Gorbachev KGB operative who sent Oleg back to America in the final season. Oleg, it seems, will be prosecuted for espionage, likely never returning to his wife and newborn baby. Philip and Elizabeth's return to their homeland is bittersweet, as the two tearfully try to convince each other their children will be fine in America without them, and ruminate on what their lives could have been had they not been recruited to be spies.

The show leaves plenty of questions unanswered, though many of them may be moot. We never see Philip reunited with Misha, his adult son, though that reunion could certainly happen now. Even if Renee was a Russian operative, it likely didn't matter, as there wasn't much time left in the Cold War. It's never explicitly stated if the Gorbachev coup by the KGB splinter faction still takes place, but history of course tells us it didn't, and the Soviet Union would be dissolved less than five years after the events of the finale anyway. Philip and Elizabeth have returned home to a country they gave their entire existence to, and it's very close to its ultimate defeat. The transgressions of their last days in America may muddy how they're welcomed back, and while they still have each other, it likely won't be long before they realize they paid too high a price for a losing cause.
