Turtlenecked Jeffster! (Jeff's even wearing round glasses) sings Leaving on a Jet Plane, as Ellie drinks and drinks, trying to pretend she doesn't care. Awesome videos it all. Back-and-forth shots of the sad party song and Chuck and Sarah walk and talk about how weird this will be. He's never lived outside of California, but she's lived all over the world and only ever felt at home in Burbank. When Jeffster! finishes their song, they invite Ellie and Awesome up for a few words. Later, at the coffeeshop, some agents show up to get Arnaldo from Morgan and Casey. Morgan introduces himself as "M. Grimes," saying he can't tell them what the "m" stands for. He asks them where they're stationed, and they say Lake Cuomo, so he asks a bunch of stuff about it, having read his guide book, and they don't know anything about the place. In other words, Morgan's geekiness catches them in a lie. They're not the agents, of course. Casey draws his gun, but then a bunch of others surround them with their own guns. Morgan sees the hottie, and says, "O, Canada."
Chuck and Sarah are still all melancholy about running away, but then he asks if it's what she really wants. She says she thought it was one way or the other, but maybe... Then the Interpol agents who they knocked out point guns and ask what the hell they've done with Juan Diego Arnaldo. Aaaaand they're handcuffed together again. Interpol guys fill Chuck and Sarah in that the other Interpol agents sent to retrieve Arnaldo were found dead. Sarah and Chuck worry about Morgan and Casey, and try to convince the guys that their friends are in trouble. The Interpol guys don't listen, so Chuck and Sarah punch them and start to run. Meanwhile, fake Canadian hottie is torturing Arnaldo to find out what he's told them. Morgan wants to send out a signal to the CIA to alert them, but Casey says the only agents within 100 miles just quit.
Cue our agents: Chuck drives up with Sarah on the front of his scooter and they see Casey and Morgan. They drive on through the glass storefront, and Chuck kung-fu flashes. He and Sarah work together to kick all the bad guys' (and girl's) asses. It's practically like dancing and is pretty awesome. Chuck can't hit a girl, so Sarah takes that one. And Morgan and Casey do a little tied-up spin move to take an agent out too. When they've won, Sarah and Chuck say they're going to catch their train when Juan Diego tells them he's been on the run and he can tell they don't really want that. Chuck and Sarah wonder if they can go back and tell General Redhead everything, and have a real shot at having it all. They agree not to quit the spy life and be together, with more "I do"s. Then they kiss. Morgan loves it, but Casey practically gags.
