Darcy's letter confronts Lizzy with two irreconcilable versions by Darcy and Wickham. She is obliged to choose between Wickham's plausible, physical manner and Darcy's authoritive written account of events. Ch. 36 shows her swift changing reaction from astonishment and horror, then as she re-reads the letter to the realization Darcy is blameless concerning any injustice to Wickham. At first I wondered how her deep-rooted prejudice of Darcy could be removed so quickly until the O.N reminds us Lizzy had never seen any instance of good or benevolence in Wickham's behaviour that might prove Darcy to the contrary. Wickham's own appearance of charm finally undoes him with Lizzy. Although upset, she peruses Darcy's letter with intelligence and comes to the moment of intense self-realization '...Till this moment I never knew myself' Lizzy maybe too hard on herself. Yet she perceives her own pride and prejudice. I notice she uses both words on herself.
