Elizabeth encounters Darcy again on a visit to the newlywed Mr. and Mrs. Collins, as he arrives to visit Lady Catherine at Rosings Park, the estate to which Mr. Collins's living is attached. She tolerates him, unaware of his growing admiration, and is astounded when he suddenly proposes to her. His offer is high-handed and condescending 鈥?he does so, he says ';against his own will'; and in spite of her objectionable family. He is stunned and mortified to be rejected in no uncertain terms: Elizabeth tells him he is ';the last man in the world whom [she] could ever be prevailed on to marry';.
