"But whatever may be the sentiments which Mr. Wickham has created, a suspicion of their nature shall not prevent me from unfolding his real character -- it adds even another motive." If Darcy is not hinting that she may have been captivated by Wickham, what sentiments do you think he means? Why would Darcy's plan to forget his proposal and try to get over his love for her keep him from such a hint?

As far as Lizzy being at fault in not believing Bingley, I take that as a given. If I understand you correctly, you are saying that it was Darcy's love and respect for Lizzy that made him believe her, so it's not really to his credit? As I think I wrote, I take this acceptance on his part as further evidence that he does not stick stubbornly to first impressions as she does, as evidenced by his turnaround about her looks and her continued resentment of his initial insult. Lizzy had no good reason not to believe Bingley, except for her prejudice. It's true, she wasn't in love with Bingley, but her sister was, and she liked and respected him. She also said she understood Bingley's character perfectly. So I guess we'll have to disagree on this one.
