Since Mr. Bennet's property is entailed away from his daughters, their cousin Mr. Collins will inherit Longborn, enabling him to throw out the remaining Bennet family when he chooses. However, Mr. Collins is eager to make amends with the Bennet family, and due to the encouragement of his patroness, Lady Catherine de Bourgh, has decided it is time for him to marry, so why not one of the Bennet girls? Mrs. Bennet directs him to Lizzie, so as not to disrupt Jane's relationship with Mr. Bingley.
As Lizzie dodges the advances of Mr. Collins at every chance, she makes a new friendship with Mr. Wickham, who has known Mr. Darcy for his entire life. He tells Lizzie that Mr. Darcy destroyed the future he planned, so that he had little choice but to join the army. This gives Lizzie even more reason to dislike Mr. Darcy.
