Iago, acting as a "friend" to Othello, warns him an angry Brabantio is on his way. However, Cassio arrives with a message from the Duke of Venice: Othello must go and fight off a Turkish invasion. Before Othello can leave, Brabantio arrives and accuses Othello of using witchcraft on his daughter. Brabantio then follows Othello and the others to see the Duke, hoping to air his grievance there.
Iago's nature as a master manipulator is further demonstrated as he tries to manipulate Othello into getting angry at Roderigo, and as he acts like Othello's friend just after insulting him in such crude terms at Brabantio's. Othello, at this point, is full of confidence and doesn't take the bait. He's confident he performed admirably in the military, and his love for Desdemona is real, so he doesn't fear Brabantio. As if to validate Othello's confidence, Cassio arrives with his summons from the Duke of Venice. This scene sets up Othello as a truly important leader and an admirable military man.
