The dock where Illya knocks out the policeman and drops his uniform into the water is the same dock used in the episode with the plague outbreak in Scotland ("The Finny Foot Affair").
In the episode, Terbuf is a fictional Balkan country somewhere near Albania, which Illya Kuryakin calls "the land of the eagle". In real life, Tërbuf is a village in Albania, and the Albanian name for Albania (Shqiperia) can mean "the land of the eagle".
