Elizabeth receives two letters from Jane, and learns that Lydia has run off with Wickham.
A few minutes later, as she is jumping up to tell the Gardiners that they must leave immediately, Mr. Darcy enters the room.
She relays her news, she cries, she excites compassion in him – all at the same time. Elizabeth thinks that surely he must be more disgusted than ever to hear about this weakness in her family.
After he leaves, she wonders with regret whether she will ever see him again.
According to her letters, Jane, always the optimist, thinks that Mr. Wickham will marry Lydia. Elizabeth is much more of a realist. Lydia has no money, so there's nothing to tempt Wickham to marry her.
The Gardiners arrive, hear the news, and they all proceed to make arrangements to immediately bring Elizabeth home.
