Final answer:
The excerpts provided do not mention the characters Cyrano, de Guiche, or Roxane, thus making it difficult to address the specific plot point in question accurately.
Step-by-step explanation:
The student's question seems to reference an event from a piece of literature, which may suggest they are asking about the plot of a story or play involving the characters Cyrano, de Guiche, and Roxane. However, none of the provided excerpts mention these characters or the specific event of Cyrano delaying de Guiche's arrival.
The provided excerpts describe events and characters from other narratives, focusing on characters like Calixta, Bobinôt, Alcée, and others within their respective stories. The student could be asking about Edmond Rostand's play 'Cyrano de Bergerac', but this cannot be confirmed without additional context.
