In this episode one of the characters is seen to be driving a VW Golf. The scene is set in Geneva Switzerland. However an American spec VW Golf is used. Also in backround shots, American vehicles not avalible in Europe are seen. Another scene shows the police race past in two Skoda Rapides. This car has not been made since the early 90's and it is highly unlikely that the Swiss Police would be using these cars still. The shot is an old video that appears to have been shot in an Eastern European country.
Except for the pilot, all of the show's season 1 episodes are named after Led Zeppelin songs, and all of the current season 2 episodes are named after R.E.M. songs.
