Love her too. In Chap. 25, Wickham (the blabbermouth), after meeting her proceeds to give her an account of Mr. Darcy's mistreatment of him.

"Mrs Gardiner had seen Pemberley, and known the late Mr. Darcy by character perfectly well. Here consequently was an inexhaustible subject of discourse. In comparing her recollection of Pemberley, with the minute description which Wickham could give, and in bestowing her tribute of praise on the character of its late possessor, she was delighting both him and herself. On being made acquainted with the present Mr. Darcy's treatment of him, she tried to remember something of that gentleman's reputed disposition when quite a lad, which might agree with it, and was confident at last that she recollected having heard Mr. Fitzwilliam Darcy formerly spoken of as a very proud, ill-natured boy."
