A pair of fine eyes - Darcy on Elizabeth

"I have been meditating on the very great pleasure which a pair of fine eyes in the face of a pretty woman can bestow."
Miss Bingley immediately fixated her eyes on his face, and desired he would tell her what lady had the credit of inspiring such reflections. Mr. Darcy replied with great intrepedity:
"Miss Elizabeth Bennet."

– Jane Austen

Pride and Prejudice, Chapter 6. Mr. Darcy seems lost in thought at a party in the Lucas house and Caroline Bingley suggests that he must be thinking how insufferable it is to spend evenings with such insipid and self-important people. But Darcy shocks her with his response, admitting that he has been thinking about Elizabeth Bennet’s fine eyes. Caroline sees Elizabeth as her rival for Darcy’s affections and is astonished by Darcy’s revelation.
