I'm looking for a fic or KU book that has Elizabeth embarrassed by Darcy. I believe D&E were being forced to marry, so there was a luncheon held at Darcy's townhouse and many of his friends were there. Caroline Bingley brings up Darcy's comment "I'd sooner call her mother a wit" in front of everyone - Lizzie doesn't make a scene but Georgiana is furious with Darcy and gives him a set down.

I cannot remember anything else but I'm hoping someone can help me find this book/fic?
