Well,we're at the end of another great GR and I'll just wrap up my

mirror theme here-by the end of the book,Wentworth has finally made
his move after seeing Anne's real feelings thru her conversation with Harville(one of the best moments in the book) and she not only accepts but later on,helps him to realize that most of his fears regarding their reunion were in vain:

" But I too have been thinking over the past, and a question has suggested itself, whether there may not have been one person more my enemy even than that lady? My own self. Tell me if, when I returned to England, in the year eight, with a few thousand pounds, and was posted into the Laconia, if I had then written to you, would you have answered my letter? Would you, in short, have renewed the engagement then?"

"Would I?" was all her answer; but the accent was decisive enough.

"Good God!" he cried, "you would! It is not that I did not think of it, or desire it, as what could alone crown all my other success; but I was proud, too proud to ask again. I did not understand you. I shut my eyes, and would not understand you, or do you justice. This is a recollection, which ought to make me forgive every one sooner than myself. Six years of separation and suffering might have been spared. It is a sort of pain, too, which is new to me. I have been used to the gratification of believing myself to earn every blessing that I enjoyed. I have valued myself on honourable toils and just rewards. Like other great men under reverses," he added, with a smile, "I must endeavour to subdue my mind to my fortune. I must learn to brook being happier than I deserve."

And how does their marriage reflect on the others? Mary is the most pleased(just as long as Anne doesn't eclipse her,status wise),Sir W approves of Wentworth's appearance and money enough to honor them by recording the event in his favorite book and
Elizabeth acts aloof,as usual.

Lady Russell adjusts because she cares more about Anne's happiness(particularly since Mr. Elliott ran off with Mrs. Clay)than trying to change her. Also,Wentworth's fortune makes it easier for her,I think,to reconcile with the whole thing-at the very least,Anne will be provided for and you can't say the same about Elizabeth in the future.
