Here's a conversation that stood out to me upon this read:

"My overhearings were more to the purpose than yours, Eliza," said Charlotte. "Mr. Darcy is not so well worth listening to as his friend, is he? Poor Eliza! to be only just tolerable."

Was she trying to comfort her friend for being assessed as merely "tolerable" or was she sort of sticking it to Lizzie a little as Charlotte had always been on the receiving end of being told she was not a handsome woman (and I'm certain Mrs. Bennet never let Charlotte forget the fact that her daughters were far more handsome than Charlotte). Do you think that Charlotte might have found a little satisfaction in the fact that in this particular situation, it was Lizzie's beauty that did not measure up (in Darcy's eyes).

Here's more:

"I do not mind his not talking to Mrs. Long," said Miss Lucas, "but I wish he had danced with Eliza."

"Another time, Lizzy," said her mother, "I would not dance with him, if I were you."

"I believe, ma'am, I may safely promise you never to dance with him."

"His pride," said Miss Lucas, "does not offend me so much as pride often does, because there is an excuse for it. One cannot wonder that so very fine a young man, with family, fortune, everything in his favour, should think highly of himself. If I may so express it, he has a right to be proud."

"That is very true," replied Elizabeth, "and I could easily forgive his pride, if he had not mortified mine."
