When Elizabeth is dancing with Mr. Darcy at Netherfield she tells him that she is trying to figure out his character. His reply, after she tells him she isn't having much luck, is "...I could wish, Miss Bennet, that you were not to sketch my character at the present moment, as there is reason to fear that the performance would reflect no credit on either."

I wonder what he can be thinking she'll end up thinking about him? Surely IMO he's thinking of the developing problem with Wickham's being in the area and how the two men are compared, but could he be aware of (and care about) the general opinions of the people in Hertfordshire?
