These chapters primarily deal with the enduring theme of class division by allowing Lizzie to hear from Fitzwilliam what had happened between Bingley and Jane, and how Darcy had achieved a "triumph," in the words of his cousin, in dealing with the issue by persuading Bingley that Jane was not in earnest. As they continue talking, Fitzwilliam explains why Darcy was so keen to release his friend from this unwelcome attachment:
"There were some very strong objections against the lady," were Colonel Fitzwilliam's words, and these strong objections probably were her having one uncle who was a country attorney, and another who was in business in London.
Clearly, however, the letter which Darcy writes Lizzie explaining why he feels so reluctantly in love with her, likewise addresses the station of her family. Class division is a constant theme and is shown as something that limits you and is depicted as something that is very difficult to transcend.
