Quote #4
Hope was over, entirely over; and when Jane could attend to the rest of the letter, she found little, except the professed affection of the writer, that could give her any comfort. Miss Darcy's praise occupied the chief of it. Her many attractions were again dwelt on, and Caroline boasted joyfully of their increasing intimacy, and ventured to predict the accomplishment of the wishes which had been unfolded in her former letter. She wrote also with great pleasure of her brother's being an inmate of Mr. Darcy's house, and mentioned with raptures some plans of the latter with regard to new furniture. (24.1-2)
New furniture is just a cover for Caroline Bingley's real purpose in writing—to tell Jane that she'd better quit thinking she's ever going to marry her brother.
Quote #5
But why Mr. Darcy came so often to the Parsonage, it was more difficult to understand. It could not be for society, as he frequently sat there ten minutes together without opening his lips; and when he did speak, it seemed the effect of necessity rather than of choice—a sacrifice to propriety, not a pleasure to himself. He seldom appeared really animated. (32.29)
Mr. Darcy is actually taking Lizzy's advice here and practicing talking to people he doesn't know well. (It doesn't seem to be going very well.) But she's so convinced that he's an arrogant jerk, she doesn't even see what he's doing.
Quote #6
As to his real character, had information been in her power, she had never felt a wish of inquiring. His countenance, voice, and manner had established him at once in the possession of every virtue. (36.4)
We'd like to blame Wickham for setting out to deceive the entire town, which he did. But Lizzy also blames herself: she set herself up to be deceived by focusing on his pretty face.
