She respected, she esteemed, she was grateful to him, she felt a real interest in his welfare; and she only wanted to know how far she wished that welfare to depend upon herself, and how far it would be for the happiness of both that she should employ the power, which her fancy told her she still possessed, of bringing on the renewal of his addresses.

– Jane Austen

Pride and Prejudice, Chapter 44. Elizabeth realizes the power she has over the changed Darcy. She believes that she holds his heart and the happiness of both of them in the palm of her hand, after his tenderness towards her in her stay at Pemberley. This passage suggests that she too loves him and wishes him to propose a second time. This is foreshadowing of Darcy’s second marriage proposal and Elizabeth’s acceptance of it.
