In Sophie Kinsella's novel "Wedding Night," the character's exasperation with another character's reliance on Mr. Darcy as a reference highlights a common frustration with literary allusions. The quote expresses a feeling of defeat or resignation when faced with someone using an iconic figure from classic literature to support their points. It suggests that the speaker believes this tactic undermines the seriousness of their discussion or argument.

This sentiment reflects a broader commentary on how classic literature, like Jane Austen's work featuring Mr. Darcy, is often invoked in modern conversations, sometimes to the detriment of the discourse. The quote captures the humor and frustration of the characters as they navigate their relationships and the complexities of love, drawing parallels to the timeless themes presented in Austen's narratives.
