After Tom returns, he encourages the young people to begin rehearsals for an amateur performance of the play "Lovers' Vows". Edmund objects, believing Sir Thomas would disapprove and feeling that the subject matter of the play is inappropriate for his sisters. But after much pressure, he agrees to take on the role of the lover of the character played by Mary. The play provides further opportunity for Henry and Maria to flirt. When Sir Thomas arrives home unexpectedly, the play is still in rehearsal and is cancelled. Henry departs without explanation and Maria goes ahead with marriage to Mr Rushworth. They then settle in London, taking Julia with them. Sir Thomas sees many improvements in Fanny and Mary Crawford initiates a closer relationship with her.
