Character Role Analysis
Le Bret isn’t exactly the most complicated character. In fact, you could make the argument that he’s around solely to point things out to us. He tells us about Cyrano’s character in the first act, points out to Cyrano that he seems to have a penchant for making enemies, makes the comment that Cyrano would rather have Roxane than his ideals, and rants about Cyrano’s overblown chivalry.
All of these are helpful pieces of information for us to notice. So just think of Le Bret as your own personal tour guide through Cyrano de Bergerac.
