The words "fondly" and "entreaty" in the last sentence suggest that Mr. Pontellier is expressing a genuine emotional appeal to Edna. By using "fondly," it indicates that he has a warm, affectionate feeling towards her, showing that he cares about her well-being. The use of "entreaty" implies a sense of pleading or earnest request, suggesting that he is seeking her presence with a degree of vulnerability.
Given this context, the most accurate interpretation would be:
He has changed his strategy to persuade Edna to come inside.
This indicates that he is moving from a more demanding or assertive approach to one that is more emotionally appealing and gentle, reflecting his desire for connection with her.
