Volume II covers from Chapter 24 to 42. It begins with confirmation of the Bingleys having left Netherfield House and settled in London. Jane goes to London and is snubbed.

It ends with Lydia going off to Brighton and Elizabeth off to Derbyshire with her Aunt and Uncle Gardiner.

How will Elizabeth and Darcy be reconciled if it is true? How could Wickham be so scandalous? Will Elizabeth and Darcy meet again? Will their pride and prejudice be conquered or will it prevail?
She grew absolutely ashamed of herself. Of neither Darcy nor Wickham could she think without feeling she had been blind, partial, prejudiced, absurd.
After wandering along the lane for two hours, giving way to every variety of thought—re-considering events, determining probabilities, and reconciling herself, as well as she could, to a change so sudden and so important, fatigue, and a recollection of her long absence, made her at length return home ....
