With Arthur away shooting, Phyllis and Jack seize the opportunity to pose Jack's air transfer scheme to Geoffrey. Phyllis invites Geoffrey for dinner and is surprised when he includes Penelope, his mistress. Nanny, Gates, and Mrs. Gates compare the behavior of Larkfield Manor's guests to that of the immoral Edward and Mrs. Simpson. Jack realizes that one person stands in the way of Geoffrey's financial support. Phyllis confronts Geoffrey about Penelope, and later, she gleefully dashes Penelope's illusion of becoming mistress at Layford Park.
