Count de Guiche is now the Duke of Grammont. By Act V, scene ii, fifteen years have passed, and the Duke is talking with Roxane in the convent where she lives. The Duke has softened considerably from the violent, angry, and bitter man he was earlier. Cyrano's kindness, heroism, and respectability have helped to make the Duke a better person by the end of the play. Roxane tells the Duke that Cyrano visits her every week, giving her all of the gossip. Le Bret enters and expresses concern for Cyrano. The Duke says no one should feel sorry for Cyrano because he "has lived out his vows,/Free in his thoughts, as in his actions free!". He now respects Cyrano and probably envies the life he's led. The Duke goes on to say , "Yet I were proud to take his hand!" He then warns Le Bret that he's heard rumors that people want to harm Cyrano, so he should be careful.
After fifteen years, the Duke has matured and become wise is his older age. Cyrano's life has led the Duke to now admire him for his independence and finally understands why Roxane is so loyal to him.
