Final answer:
Lydia shows no shame in the circumstances of her marriage to Wickham.
Step-by-step explanation:
In Lydia and Wickham's marriage, the person who shows no shame in the circumstances is Lydia herself.
Despite the disapproval and potential scandal surrounding their elopement, Lydia does not seem to feel any guilt or distress. This is evident from the quote, 'What terrible thing bound them and locked their lips, when they showed neither consciousness of guilt toward their benefactress nor distress at the slow wearing apart of long-established and dear ties?' Lydia's lack of shame and her naive behavior contribute to the complications and conflicts in the story.
