In this chapter, we begin to see that Catherine is not at all slow on the take-up, just naive' but learning FAST the difference between a true gentleman and John, the "butt-insky." Henry speaking at the dance:

“That gentleman would have put me out of patience, had he stayed with you half a minute longer. He has no business to withdraw the attention of my partner from me. We have entered into a contract of mutual agreeableness for the space of an evening, and all our agreeableness belongs solely to each other for that time. Nobody can fasten themselves on the notice of one, without injuring the rights of the other. I consider a country–dance as an emblem of marriage. Fidelity and complaisance are the principal duties of both; and those men who do not choose to dance or marry themselves, have no business with the partners or wives of their neighbours.”
