When Bingley comes a few days later, he says Mr. Darcy has gone to London for a while but will return in ten days.
The Bennets invite Bingley to come to dinner the next day.
He comes so early that nobody's even dressed.
After dinner, Mrs. Bennet keeps winking at Kitty and Elizabeth. Elizabeth ignores her, knowing she's just trying to get Jane alone with Mr. Bingley.
Kitty finally asks all innocently, "Why do you keep winking at me, mamma?"
Mrs. Bennet tells her to hush.
Mrs. Bennet finally maneuvers them all out of the room, to Jane's distress, but Elizabeth returns as soon as possible.
Mr. Bingley fortunately ignores all of Mrs. Bennet's hints.
The next day, Bingley spends the morning with Mr. Bennet, has dinner with the family, and gets engaged to Jane.
It's taken twelve months, but, at long last, Mrs. Bennet's promise to Mr. Bennet is fulfilled. His visit to Netherfield so long ago has, indeed, produced an engagement.
Now come lots of congratulations and happiness and Mr. Bennet's teasing.
Mr. Bingley starts coming every day and, when he and Jane aren't attached at the hip, one of them is talking Elizabeth's ear off.
Jane wishes that Elizabeth could be as happy. Elizabeth says that it's impossible – she's not made like Jane.
In her own dry manner, Elizabeth says she only hopes that she have good enough luck to find another Mr. Collins. Hah!
