My first exposure to P&P was watching P&P1 on PBS when it was first broadcast. Attempting with these comments to stay with only the chapters assigned to date for this GR, and remembering what I thought on that first viewing, I am simply amazed that you were able to pick up on all these clues to Wickham's personality! My thoughts then, and to date with our chapters in this GR, before reading these clues you've found, are that perhaps Mr. Wickham would be a good match for Elizabeth.
