In Chapter 32, as Charlotte is "playing Emma" for her friend Lizzy, there is a passage that goes:

In her kind schemes for Elizabeth she sometimes planned her marrying Colonel Fitzwilliam. He was beyond comparison the pleasantest man; he certainly admired her, and his situation in life was most eligible; but, to counterbalance these advantages, Mr. Darcy had considerable patronage in the church, and his cousin could have none at all.
