A brawl breaks out. Iago's plan is going according to his evil ideas. Iago pretends he is trying to intervene. After hearing an alarm going off, Othello comes into the area of the brawl. He demands that the brawlers stop.

Othello is highly upset with Cassio. He fires him on the spot. Desdemona is awakened. Othello is enraged that his love has come to stir about.

Iago pretends to be grieved about the whole brawl. Iago convinces Othello that he will be on guard and protect the peace.
