The scene opens and Ted continues his effusive love confession to Robin, explaining that they're great together even five years after they officially ended. Ted leaves Robin to give her some time to consider his confession; as she quite taken aback by it. She needs, about two minutes before she's back down in their apartment, knocking on his bedroom door and planting a big, fat one on him; things might work out for them after all from the looks of it. Robin and Ted are trying to wrap their minds around their new confessions of love when Robin's arch nemesis, Patrice, knocks on the door. Apparently, the two need to hightail it to the airport to catch a train to Russia where they're covering a butter festival for World Wide News.
Yes, though Robin referred to Patrice as her arch nemesis, this was the first time we were meeting Patrice. With Robin now gone, Ted calls Marshall to demand a morning powwow to debrief him on what just transpired; he wants seriously talk this over with them. Marshall rouses Lily, and they're treated to a delightful and unexpected surprise of a third bedmate spooning them. It's Barney, who ended up in the suburbs after a maddening night on the drunken train. Marshall heads out to meet Ted, but is followed closely behind by Lily. Clad in very skimpy bedroom attire, she's trying to escape from a hung-over and leering Barney. As she heads off, she warns Barney to keep out of their stuff.
Barney's interpretation? Find. A. Sex. Tape. Surely there must be one! So he calls his housekeeping minions and as they tear the house top to bottom, he finds something much, much better: Long-Term Bets, a box Lily and Marshall have filled with bets they have placed over the years (Marshall bets Lily that Robin will never return their hairdryer; Lily bets Marshall that Ted will go bald; it goes on). Consider the jackpot hit. Over at McLaren's, Ted is recounting to Lily and Marshall what just happened with Robin. One thing of note about this scene was showing the two interpretations of Robin's departing words of "We'll continue this when I get back," to Ted. In Ted's mind, Robin said it in a sultry, suggestive way, but Lily points out that Ted could be remembering it the way he wants to, and Robin could actually have put it much more cautiously.
It's all in the intonation. After hearing what went down with Robin, Lily and Marshall are giving Ted conflicting advice: Lily's words of wisdom? Go to Russia! Surprise her! Fill her voicemail with messages! Basically, she's only offering suggestions that would surely push Robin away, while Marshall's response is more subdued and possibly more sensible. If only Ted knew that Lily's sabotage was due to her betting Marshall that Robin and Ted would never end up together; and thus her twisted advice. Oh, but wait, he's about to find out...Persuaded by Lily to rush off after Robin, Ted is about to leave just as Barney enters with the bet box, ready to divulge all of its secrets. At this point, we learn that the boxes' inception was 10 years ago when Marshall and Lily were looking for a new head-rushing hobby. Because nothing provides a turn-on quite like the sweet smell of money, right?
With all the bets out on the table, Ted finds the one Lily placed saying she thinks Robin and Ted won't end up together and realizes why she was trying to interfere; much to his shock. Saddened by Lily's betrayal, he heads upstairs just as Barney bursts into his apartment. He has found the sex tape and is ready to revel in Marshall and Lily's secret sexual affairs. But before he can pop that baby in the VCR, a light bulb goes off in Ted's head: Robin is still in love with Barney. That's why her feelings for Ted never returned despite all of his continued romantic gestures. Now that the cat's out of the bag, Barney tells Ted everything about the recent events with Robin, from their taxicab kiss, to subsequently ending his relationship with Nora. What Barney didn't know, however, was that Robin and Kevin have broken up, and as Ted drops the bomb, Barney, (in a rather surprising move) doesn't care. Whether she's with Kevin or Ted, Barney just wants Robin to be happy.
Barney's selflessness and maturity might be due to a massive foreshadowing of an impending reunion between the two; it seems from the way things are shaping up. With Barney's approval to go forth and prosper with Robin, Ted picks her up at the airport, whisking her off for a little date down memory lane (hey there, blue French horn). It all seems to be in typical Robin and Ted fashion, but when they arrive back at their apartment, the reality sets in.
"Everything in my life is unstable," Robin tells Ted. "You're one of the few things that I can count on. I really don't want to mess that up." And with that, we bid adieu to the storyline that came and went, quickly and cleanly. Or did it?...After hearing Ted say that he knows ending it with Robin was for the best, Marshall heads up to Robin's room to tell her what he knows Ted can't: ''You got to move out," he says; much to Robin's surprise. The episode ends.
