Elizabeth is anxious to get back home; she is afraid they are overstaying their welcome. Yet her mother is anxious for them to remain, hoping that, the longer Jane is at Netherfield, the greater the chances are of a proposal from Mr. Bingley. To this end, she refuses to send a carriage to bring her daughters home.
Elizabeth and Jane ask if the Bingleys will send them home in their carriage. They are induced to stay for one more day, for the sake of Jane's health, and then they will be allowed to go home.
We learn that Miss Bingley likes Jane, but she is jealous of Elizabeth.
Knowing that he only has to control his passion for one more day, Darcy avoids Elizabeth like she has cooties – or the plague. When they're left alone for a half-hour in the study, he pretends to be absorbed in his book.
The next day, Mr. Darcy is glad to see them go. He is too attracted to Elizabeth and Miss Bingley teases him too much about the young lady for his comfort, especially since there is some real truth in her teasing.
