After the ball, Darcy and Bingley's sister Caroline discuss her brother's infatuation with Jane and agree that such an alliance will be disastrous for him. To prevent the alliance, they further agree to get him back to London and, once there, Darcy will convince him that the emotional connection is slight and the practical drawbacks are huge. Although Darcy still feels drawn to Elizabeth, his problems with her cause him to think he is doing Bingley a favor by separating him from Hertfordshire and the Bennets.
