What if Bingley immediately returned to Jane... and Elizabeth quarreled with Darcy during the wedding.
Elizabeth knew why Darcy had tried to stop Bingley from marrying Jane: He was selfish, cruel and unfeeling.
Jane and Bingley thought he counselled against the marriage because he really believed Jane to be indifferent. That was hopelessly naive.
Elizabeth wasn't naïve.
At the wedding, Darcy said that he was happy for the couple, and he even might follow Bingley's example and marry for love. Elizabeth wasn't going to let him lie to her. Not after he tried to hurt Jane. She told him what she truly thought of him.
Now Elizabeth realizes she was horribly mistaken about Darcy's character. Now she loves him. But is it too late for her? Has she lost his esteem forever?
