Othello confronts Desdemona, and then smothers her in their bed. When Emilia arrives, Desdemona defends her husband before dying, and Othello accuses Desdemona of adultery. Emilia calls for help. The former governor Montano arrives, with Gratiano and Iago. When Othello mentions the handkerchief as proof, Emilia realizes what her husband Iago has done, and she exposes him, whereupon he kills her. Othello, belatedly realising Desdemona's innocence, stabs Iago but not fatally, saying that Iago is a devil, and he would rather have him live the rest of his life in pain.
