But now several minutes elapsed without bringing the sound of [Darcy's] voice; and when occasionally, unable to resist the impulse of curiosity, she raised her eyes to his face, she as often found him looking at Jane as at herself, and frequently on no object but the ground. More thoughtfulness, and less anxiety to please than when they last met, were plainly expressed. She was disappointed, and angry with herself for being so.
Darcy's visit is anticlimatic. Elizabeth received the letter from her aunt stating Darcy's "heroics" and the assumption of Mr. and Mrs. G that Darcy had "another interest in the affair." Her own intuition is telling her the same thing, though she is trying to talk hersel out of it.
After that build up, she learns Darcy is coming to her home. She is all anticipation.
The colour, which had been driven from her face, returned for half a minute with an additional glow, and a smile of delight added lustre to her eyes, as she thought for that space of time that his affection and wishes must still be unshaken.
Then Darcy is there. And says nothing, pays more attention to her sister and basically twiddles his thumbs. What a disappointment!
