Analysis
Caroline writes back: Bingley will certainly be gone for awhile and everyone is delighted with Darcy's sister, Georgiana. Jane tries to put on a brave face, telling Elizabeth that Bingley has not wronged her and refusing to believe that Caroline has ulterior motives.
Jane again insists on seeing only the bright side, denying even her own hurt feelings. It's the opposite of prejudice, but it makes her just as blind as the prejudiced Elizabeth.
Elizabeth is disgusted that Bingley could be so weak as to let his sisters and friend determine his affections. She cites him and Charlotte as examples of human inconsistency. But Jane tells Elizabeth she judges them too harshly.
Elizabeth complains that Bingley can't direct his own true feelings. This is ironic since Elizabeth's affections and prejudices are being guided by Wickham's suave lies.
