At their first meeting the Cottons are amused and interested by the Mortmains. When they pay a call the very next day, however, the inexperienced Rose flirts openly with Simon and makes herself look ridiculous. Both brothers are repelled by this display and, as they walk away, Cassandra overhears them resolving to drop all acquaintance with the Mortmains. After an amusing episode involving a fur coat, however, all is forgiven and the two families become good friends. Rose decides that she really is taken with Simon, and Cassandra and Topaz scheme to get Simon to propose to her. Simon falls in love with Rose and proposes to her.
