As the person who pointed this out to me said, "do you expect me to rejoice in the inferiority of your circumstances?" and Darcy's entire disastrous first proposal is exactly the kind of thing you can imagine Arthur saying. (Though hopefully not to Gwen; he is getting better in this regard when it comes to her. With Merlin, otoh, mutual insults are part of the conversational modus operandi...) Plus Sophia's dad as Catherine de Bourgh = genius. As is Cedric as Mr. Collins.
