Elizabeth is back to hating when she realizes that the only time the sisters care about Jane is when she's around—not when she's upstairs in bed, sick.
Miss Bingley is preoccupied with (1) capturing Mr. Darcy's attention and (2) ragging on Lizzy behind her back.
They totally don't believe she walked three miles just to help her sister. On top of that —horror of horrors —her petticoat was dirty when she arrived because she walked all that way through the mud.
Both the dudes defend her, but the women are too busy laughing about the fact that the Bennets have relatives who live in Cheapside, an unfashionable neighborhood in London. Apparently that totally dooms their marriage prospects.
When Elizabeth comes back, they move onto other conversation topics. Like Mr. Darcy's accomplished little sister.
So, what does it mean to be "accomplished," anyway?
A lot, apparently. Mr. Darcy suggests that very few women are truly accomplished —he himself knows of only about half a dozen that fit the definition. Miss Bingley defines such a woman as able to sing, draw, and dance, while Mr. Darcy adds that, on top of all of that, she should read a lot—and not Twilight, either. You know, serious stuff. Award-winning stuff.
Elizabeth rolls her eyes. She doesn't know any woman who has all those qualities of elegance, education, and taste. (Apparently, she's never met Gwyneth Paltrow.)
