]She didn't disbelieve him because Darcy has a good character (if indeed he does -- we don't know yet) or because Wickham has a bad character (if he does).

You bring up a good point about not knowing something yet. I find one of the hardest things about a reread, is trying to stay in the moment. I find myself wanting to make conclusions and statements that include information we haven't been given. There would be no point for GRs, I suppose, if we were going to talk about the book as a whole since we have the individual boards for this very purpose---discussing JA's works in their entirety whenever we want. That's what makes the rule for discussing only the week's portion a good one, it forces us to read and discuss the book as it was intended by the author as one does on the first read. Forehand knowledge does have its benefits though. Having future information about character and plot does help on a reread to notice many things you wouldn't have noticed.

When I read the section where Wickham is talking to Lizzie at her aunt's, I wrote a comment in the margin that I wanted to post but could not do it because my observation can't be made without including information that has not been revealed. So I flipped forward to the point where this information comes up and made a notation for myself to go back to page so and so to make the comment at that time. Otherwise I might forget. Hoping this little tip will be helpful to others. :-)
