#8 To what extent does the play employ narration as a means of dramatic exposition? Whe effects on the audience do the expository methods have?

Iago's self-focus in his goal to obtain position of Lieutenant is obvious through his fickle personality. Iago is ironically viewed as an honest man, even pronouncing his reputation to Cassio, "As I am an honest man..." (act II scene iii line 244). There is much dramatic irony as Othello perceives Iago to be an honest man and Roderigo knows the plotting Iago, who claims to be helping Roderigo win over Desdemona. Iago exposes his two-faced personality, though only the audience is ever fully aware of it. One way Iago does this is by switching back and forth between iambic pentameter when speaking formally to Othello and the Duke and then prose when speaking informally to Cassio and Rogerigo; Iago puts on a show in front of Othello. Iago works with Roderigo, seemingly controlling Roderigo to expose any indecency of Cassio's. Manipulation is apparently Iago's number one tactic; he isn't out to follow Othello, but to seek revenge for not being chosen as Lieutenant. To the character's eye, Iago is a humble man, always at the right place at the right time, but to the audience Iago is deceivingly forming situations for his benefit.
