I am taken by JA's descriptions of Elizabeth's reaction to having to deal with Wickham, after finding out what a snake he is:

"She lost all concern for him in finding herself thus selected as the object of such idle and frivolous gallantry ... could not but feel the reproof contained in his believing, that, however long, and for whatever cause, his attentions had been withdrawn, her vanity would be gratified, and her preference secured at any time by their renewal."

"While she spoke, Wickham looked as if scarcely knowing whether to rejoice over her words, or to distrust their meaning. There was a something in her countenance which made him listen with an apprehensive and anxious attention ..."

"Wickham's alarm now appeared in a heightened complexion and agitated look; for a few minutes he was silent, till, shaking off his embarrassment, he turned to her again ..."

"She saw that he wanted to engage her on the old subject of his grievances, and she was in no humour to indulge him. The rest of the evening passed with the appearance, on his side, of usual cheerfulness, but with no farther attempt to distinguish Elizabeth; and they parted at last with mutual civility, and possibly a mutual desire of never meeting again."
