Lady Catherine denounces Darcy's marriage, then reluctantly restores contact when affection and curiosity overcome injured pride.
Lady Catherine de Bourgh answers Darcy's engagement letter with abusive language, especially against Elizabeth Bennet, and for a time all intercourse ends. Her rage fulfils the opposition she threatened at Longbourn, but it cannot alter Darcy's choice or his marriage.
At Elizabeth's persuasion, Darcy later seeks reconciliation. Lady Catherine resists a little longer, then yields either to affection for her nephew or curiosity about the wife she had called a pollution of Pemberley, and condescends to visit. Her return does not erase her pride; it shows the limits of an authority she had assumed was absolute.
She is a tall, large, handsome English aristocratic woman with strongly marked features, a commanding air, and a richly authoritative manner. Her hair, complexion, age, and dress are not specifically described.
She is the defeated family autocrat who eventually accepts contact with the marriage she could not prevent.
