When Rawdon discovers Rebecca in her treachery, he is convinced that money means more to her than he or the son whom she has always hated. He refuses to see her again and takes a post in Coventry Island, where he dies of yellow fever.
Because her parents are starving and she can neither provide for them nor give little Georgy what she thinks he needs, Amelia gives up her son to his grandfather Osborne. William Dobbin comes back from the service, reconciles old Osborne to Amelia, whereat Osborne makes a will leaving Georgy half of his fortune and providing for Amelia.
Rebecca, having lost the respectability of a husband, wanders in Europe for a couple of years and finally meets Joseph, Georgy, Amelia, and William on the Continent. Rebecca sets about to finish what she started to do at the first of the book — that is, to ensnare Joseph. She does not marry him, but she takes all his money and he dies in terror of her, the implication being that she has, at least, hastened his death.
At the end of the book Rebecca has the money necessary to live in Vanity Fair; she appears to be respectable. William has won Amelia. Rebecca has been the one who jolted Amelia into recognition that George, her first love, wasn't worthy.
Little Rawdon, upon the death of his uncle Pitt and his cousin Pitt, becomes the heir of Queen's Crawley. Little George, through the kindness of Dobbin, has lost his distorted values obtained in Vanity Fair. The reader feels that these young persons of the third generation will be better people than their predecessors in Vanity Fair.
