Final answer:
The provided excerpts are from various literary works and do not pertain to 'Cyrano de Bergerac', therefore an answer regarding Roxane's forgiveness of de Guiche cannot be given based on this information.
Step-by-step explanation:
The question pertains to the forgiveness of a character in the play 'Cyrano de Bergerac', but the excerpts provided seem to be from Henrik Ibsen's 'A Doll's House' and other literary works, which do not contain any information about the character de Guiche or Roxane from 'Cyrano de Bergerac'. It is not possible to answer the question about Cyrano de Bergerac's characters based on these excerpts. To accurately determine whether Roxane has forgiven de Guiche by the end of 'Cyrano de Bergerac', one would need to refer specifically to the text of that play.
