“You have shown that you can dance, and you know we are not really so much brother and sister as to make it at all improper.” “Brother and sister! no, indeed.”
– Jane Austen
Emma, Chapter 38. This exchange between Emma and Mr. Knightley when he asks her to dance at the Westons’ ball is foreshadowing of their feelings of romantic interest in one another. They hint at the possibility of a relationship that is more than just brother and sister.
