Mainwaring has nearly had two affairs. One is in Mum's Army with a woman called Fiona Gray who joins the Home Guard when they recruit female soldiers. The two start meeting in cafes all over the town. Gossip starts about them and Mrs Gray leaves by train. Another is with a bus conductress in "A Soldier's Farewell" whom Mainwaring compliments and defends when she is being flirted at. At the end of the episode, when Mainwaring dreams he is Napoleon, he dreams that the bus conductress is Marie Walewska (Napoleon's mistress). In War Dance, Mainwaring claims to have been very vexed at Mrs Mainwaring and gave her a "good dressing down" when she burnt some sausage rolls. He turns and it is revealed he has a black eye. Mainwaring claims he did it on the wardrobe door, but it was obviously done in a domestic dispute. Walker later jokes, asking if Mrs Mainwaring has a rolling pin.
