I agree that the Captain did not seek out either Kellynch or Uppercross for Anne's sake. Granted, he must have had some curiosity, but nothing beyond that. If he had really wanted to renew their relationship, he would have sought her out a long time ago. Had he wished ever to see her again, he need not have waited till this time; he would have done what she could not but believe that in his place she should have done long ago, when events had been early giving him the independence which alone had been wanting. Ch. 7

Their almost too-formal way of talking to each other is only natural. Even Darcy and Elizabeth are silent and reserved when they meet again at Longbourne post-pemberley. (P&P) what made you so unwilling to come to the point at last? What made you so shy of me when you first called, and afterwards dined here? Why, especially when you called, did you look as if you did not care about me?" "Because you were grave and silent, and gave me no encouragement." "But I was embarrassed." "And so was I." "You might have talked to me more when you came to dinner." "A man who had felt less, might." Ch. 60, P&P.
