Goof: Although Juan Diego Arnaldo, the Basque terrorist, is supposed to be Spanish he clearly has a Mexican accent.
The Polish rocker (played by Tim Loden) on the train, is Yvonne (Sarah) Strahovski's real life boyfriend.
When Chuck is calling General Beckman after getting off in the fictional Swiss city of Pündtün, the phone operator prompts, in German, for two Euros. Switzerland's official currency is the Swiss Franc.
At the 16:29 mark, the "crying baby" that the female passenger hoists up next to Morgan is clearly a doll.
When Chuck and Sarah are on the train to Zürich, the caption says they are going through "Lyon, France", and a very pretty little village in the mountains is shown. However, the village shown is not Lyon, which is the third biggest city in France.
The Swiss town Pündtün where Team Bartowski is at, does not exist, but it sounds like it could be in the eastern Swiss canton of Graubünden. Also, the fact that Arnaldo suggests they eat nut cake, supports this, as a certain type of nut cake is a specialty of the Graubünden region. However, if they took the train from Paris to Zürich, it is very unlikely that the route would lead them through the canton of Graubünden.

Casey and Morgan discover that Chuck and Sarah took the train from Paris to Zürich via Lyon at the Gare Montparnasse. But this station only serves the West and South West of France. To take a train to Switzerland, they should have gone to the Gare de Lyon.
Arnaldo: May I just say, I've been on the run for two years. And no matter how far you run, you can never run from yourself. And from what I heard from both of you, it's not what either of you really wants.
Sarah: You don't wanna quit?
Chuck: I thought that's what you wanted.
Sarah: I don't want you to choose me over something that you want for yourself.
Chuck: I want you. I want us. Do you think if we went back and we told Backman the honest-to-God, absolute truth, you think we really had a shot at having it all?
Sarah: Chuck Bartowski, do you agree to not quit the spy life and be with me?
Chuck: I do. Sarah Walker, do you agree to not quit the spy life and be with me?
Sarah: I do.
Sarah: Beckman expected us back in Burbank today. And so did Ellie and Casey and Devon. We can't just run away like this.
Chuck: Why not? (...) Sarah, for the first time since I've known you, there is nothing holding us back. And if Beckman finds out she could stop all of this. Us. I can't risk that. I won't.
Sarah: You're right.I can't go back to how it was before. (...)
Chuck: We should do what I should have done in Prague. We should run. (...) Sarah Walker, do you agree to quit the spy life with me?
Sarah: I do. Chuck Bartowski, do you agree to quit the spy life with me?
Chuck: I do.
Sarah: You know, Chuck, I can't fake this. Not with you.
Chuck: What? You've been faking it the whole time?
Sarah: No. No. No, not that. I've spotted a Basque terrorist on board. Juan Diego Hernaldo.
Chuck: I know. I flashed on him. He has a whole list of names in his room.
Sarah: Yeah. All of his contacts from the Euskadi Ta Sakatasuna.
Chuck: Oh my God, you even make terrorist groups sound sexy.
Chuck: Man, pastries for breakfast, every morning. Europe is genius.
Lester: Damn it, Jeffrey, you blew the amp. Don't you know that it's not the size of the instrument that matters, but how much and how long and how often your mother catches you playing?
Sarah: General, Chuck and I are dating...exclusively.
Beckman: I must caution you that allowing your private life to interfere with your professional one, can be dangerous...but off the record, it's about damn time!
Casey: Big job ahead of us, get some sleep.
Morgan: Can't. You see, in my head, the only way the plane remains aloft is if I'm rooting for it. So, stands to reason if I'm sleeping, I'm not rooting. I'm doing it for the good of the passengers.
Casey: Whatever, nutjob, but you wake me, you'll be the only one that dies.
Casey: Chuck's off the grid with Walker. Do the math, Grimes. (Morgan looks clueless) He's going to need a walker when Walker's through with him. (Still clueless) They're having intercourse, idiot.
Casey: You know it can take up to seven minutes to strangle someone to death. I've done it in under 30 seconds.
