Behind the guard at the embassy, there is a sign that says "Kun for toriseret personale", supposedly meaning "Authorized personnel only" in Danish, but it is actually quite meaningless. The correct Danish would be "Kun for autoriseret personale".
Next to the hotel Russeau there's a shop. The sign reads "Droog schoonmaakster" by which is meant dry cleaner.
However a dry cleaner translated in Dutch is "stomerij". Literal translation of "droog schoonmaakster" is dry housekeeper.
Marshall: (After Sydney found out about Sloan's intentions) Damn it!
Sydney: What the hell were you thinking?!?
Sloane: I'm sure you mean that in the most polite way.

"Oceanic Airlines non-stop flight to Sydney is now ready for boarding." This announcement was heard at the airport while Sydney and Nadia were waiting for Sophia. The plane that crashed in the pilot episode of Lost was Oceanic Airlines 815, flying non-stop from Sydney to Los Angeles. The reference is an in-joke since J.J. Abrams is creator and executive producer of both Lost and Alias.
Marshall: One gram of hydrosec, Lake Michigan turns into sludge. It's incredible, really, y'know? Dr. Evil sort of way... (takes his pinky and puts to his mouth)
In reference to the Austin Powers movies. More specifically, Austin Powers' archnemesis: Dr. Evil. Dr. Evil is a parody of various James Bond (007) villains, particularly Ernst Stavro Blofeld of SPECTRE , Dr. Evil routinely hatches schemes to terrorize and take over the world. He often places his little finger near his mouth which intended as a humorous "signature move" for Evil.
