Othello Acts 4 5

Question #4- Dramatic suspense is created through dramatic irony. The audience obviously knows Iago's plan and how he is deceiving everyone, but the characters do not. Someone posed the question of "How haven't the other characters figured out his plan yet?" I think the main reason for this is because of their lack of knowledge between the audience and the characters creates the effect that the characters' must be blind to Iago's tru nature. However, he has never given them reason to doubt before. If anything, he has made himself seem more reliable by telling Othello the "truth" about Cassio and Desdemona. And this ignorance is what makes the play a tragedy.
