In Chapter 24 when Mr Bennet is teasing Lizzie about being married and says "Let Wickham be your man. He is a pleasant fellow, and would jilt you creditably." Lizzie replies, "Thank you, Sir, but a less agreeable man would satisfy me. We must not all expect Jane's good fortune."
Given that we see her sense in refusing Mr Collins as a suitable partner for her in marriage what do you think she means by "a less agreeable man" (than Wickham)? Her discussion and reassurance with Aunt Gardiner about not falling in love with Wickham come later (Chapter 26), but perhaps she's already thinking those thoughts before Aunt Gardiner broaches the subject. Does she see through his charm as being somewhat superficial and there's not much depth there? In P&P2 AD has her say to Jane in Ep 1 that nothing but the deepest love will induce her into matrimony, which is not in the book. Perhaps a paraphrase of the "fine, stout, healthy love" she comments on when "discussing" the merits of poetry with Darcy at Netherfield (Chapter 9)! Is she aware that her feelings for Wickham can not be described thus?
Lots of questions, but what do you think?
