For a large portion of the book, Elizabeth directs her hate towards Mr. Darcy. His cold, haughty demeanor is such a contrast to her own playful, lively one that she has no trouble believing the worst of him (plus, he insulted her looks). Obviously, Darcy doesn't remain the novel's antagonist for too long. Soon that title switches to Wickham. Once Elizabeth starts to have feelings for Mr. Darcy, Mr. Wickham gets in the way. Soon Elizabeth starts worrying that Wickham's seduction of Lydia will drive Mr. Darcy away for good. Thankfully, that doesn't happen, though.
