Mind your language season 1 episode 10: Juan Cervantes has brought his Russian Navy friend Boris, a defector, to school. He hides him in the canteen and asks Gladys to take care of him. In class, Mr. Brown asks the students to give him words beginning with each letter of the alphabet, but Gladys interrupts to inform him that Miss Courtney wants to see him and also informs Juan to come over as she found Boris. Boris won’t tell Miss Courtney who he is or what he’s doing there, so she gets Mr. Brown to talk to him instead. Juan approaches them and tells Mr. Brown that Boris wants to stay in England, then takes him to the classroom.

Mr. Brown introduces Boris to the other students and tells them he plans on staying in England, in response to which they accuse the Russian of being a spy, a double agent and a traitor. Mr. Brown then asks him why he wants to stay in England and finds out that he had fallen in love with an English woman at Juan’s bar the previous night. His commanding officer Captain Ivan Ivanovich later arrives and wants to take Boris back. Mr. Brown tells him that he can’t because Boris wants an English wife, but Ivan tells him that he already has a Russian wife named Anastasia. Mr. Brown helps Ivan bring Boris back to the ship, but Ivan comes back because he has fallen in love with Miss Courtney.
