Meanwhile, Morgan's in the regular traveling car, where he sees a hottie with a Canadian maple leaf on her scarf. He asks if she's Canadian, and then says, "Me too, eh?" He asks if she's seen his friend, who's "aboot," but she cuts him off: "Stay away from me, or I'll cut you." Chuck and Sarah follow Juan Diego to his room, and she makes it into the room but he doesn't, when the door is kicked closed on their handcuff chain. She fights with all of her other limbs and tells Chuck she's got it, as Chuck stands in the hall, telling people who pass by that he got locked out of his room. Sarah tosses Juan Diego into the bathroom and closes the door, then opens the other one. Chuck topples in on top of her, where they land on the bed in a very sexual-looking position, her feet in the air. And that's when Casey comes in. He's disgusted, because two spies should be able to come up with a better story. Chuck swears the terrorist's in the bathroom (how does he know that?!), and Casey does find him there. He shoots him with some tranq darts and says he believes them now.

Casey asks Chuck and Sarah for an explanation, but the tranq darts hit his little notebook of numbers and names, so he runs out of the room. Casey follows and sees Morgan's blocking the path of the terrorist. He tells him to get out of the way, but instead Morgan (accidentally) uses his giant backpack to knock the guy out, then praises himself. When they're out of the train, Morgan tells Juan Diego, "We're CIA, dirtbag!" Chuck tells him it's not the best idea to share that with just anyone. But it works out well in this case, because it gives Juan Diego the opportunity to tell them that it would be odd for CIA agents to take out the Interpol agents he'd turned himself in to, and that he was going to give up names of other leaders. Casey asks if this mission was run through General Redhead, but they wanted it to be on the down-low. Morgan doesn't get why, but Casey tells him they're quitting. Morgan's so not okay with this, because, Chuck's a spy! But they tell him they want to be together, so they're quitting after handing over Arnaldo. Casey gives them keys to take their cuffs off, and Morgan's faux-Canadian hottie gets off the train and makes a phone call. She tells whoever's on the other end that someone did their job for them by neutralizing the Interpol agents, but now she'll follow Arnaldo and his new friends and make sure they never talk. In shows like this, "never talk" usually means "death."
