I thought chapter 11 brings out her desires pretty straightforwardly. I especially love the scene where she affects being above balls and other social visits to her brother:

"I should like balls infinitely better," she replied, "if they were carried on in a different manner; but there is something insufferably tedious in the usual process of such a meeting. It would surely be much more rational if conversation instead of dancing made the order of the day."

"Much more rational, my dear Caroline, I dare say, but it would not be near so much like a ball."
