FYI: In this episode Illya appears only in the first few minutes and in the last ones. Solo declares he had a father that was a lawyer and caught birds - a reference to his son hunting "thrush". The idea to brainwash Solo was apparently a coincidence: in the same year Ian Fleming wrote his latest James Bond novel, The Man with the Golden Gun, where 007 tries to kill his boss "M" after being brainwashed by the Soviets. But Fleming's book was only released the following year. Illya is kept at UNCLE HQ, replacing Mr. Waverly as a coordinator. Leo G Carroll was still on sick-leave. This was one of the few occasions when a Latin American country is called by its real name.
