When Mr. Wickham walked into the room, Elizabeth felt that she had neither been seeing him before, nor thinking of him since, with the smallest degree of unreasonable admiration. The officers of the -shire were in general a very creditable, gentlemanlike set, and the best of them were of the present party; but Mr. Wickham was as far beyond them all in person, countenance, air, and walk.
– Jane Austen
Pride and Prejudice, Chapter 16. We see two of the novel’s major themes at play here, prejudice and first impressions, when Elizabeth finds herself with George Wickham at dinner. Based purely on his looks and appearance, she finds him the most admirable of all the officers in his militia regiment. Her hasty first impressions turn out to be completely wrong when she learns to her horror and shame that he is a sexual predator and scoundrel.
