continuity and trivia

Steed and Olga pay a visit to J. Nathan Winters, and Steed asks to see some replacement handles for his umbrella - "it's a little loose" - Winters shows him a handle carved into the shape of a dog's head, which Steed dismisses. Seconds later, Winters is holding several shillelagh handles, without moving a muscle! (19:48).
Arkadi is played by the same actor - Romo Gorrara - who appears as the unnamed thug helping the First Assistant do away with Mrs Rhodes in
The £50,000 Breakfast. He appeared in
everything made in Britain in the late 60s and 70s. Another regular stuntman, Peter Clay, plays Zorick.
Steed introduces Emma to Ivan with the words "You haven't met Mrs Peel", despite them meeting in an earlier scene. This may, of course, be another send up of proper English manners, à la the opening scene of the episode.
