Final answer:
The provided excerpts do not contain a character named Opal or mention Winn-Dixie, rendering it impossible to accurately answer the question based on the given texts.
Step-by-step explanation:
The question seems to reference a specific character named Opal, who, upon ensuring that someone named Winn-Dixie is safe, goes off to talk to another character. However, based on the provided excerpts, there is no mention of a character named Opal or an event involving Winn-Dixie. It appears that the question pertains to a narrative not included in the given extracts. Each passage features different characters and scenarios, and none align with the details of Opal or Winn-Dixie. As a result, without the correct context or text, it is impossible to provide an accurate answer to the question: Who did Opal run off to talk to once she knew Winn-Dixie was safe?
