In the last paragraph of Chapter 32, Charlotte Collins (formerly Lucas) is evaluating Col. Fitzwilliam and Mr. Darcy as prospective husbands for her longtime friend Elizabeth Bennet. She thinks the colonel
…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.
I don’t understand that last part. Is she hoping Elizabeth will marry Darcy so that, after Lady Catherine de Bourgh dies, Mr. Collins might continue to be the vicar and the Collinses may stay on in the parsonage, due to Elizabeth’s advocacy for them? Or is it an oblique reference back to Wickham’s supposed desire to become a clergyman, and Darcy’s alleged blocking of it? Or does it mean something else?
