what is the outcome of the fight between roderigo and cassio

Roderigo and Cassio fight, and both are injured; Othello hears the scuffle, is pleased, and then leaves to finish off Desdemona. Iago enters, pretending that he knows nothing of the scuffle; Gratiano and Lodovico also stumble upon the scene, having no idea what has happened. Roderigo is still alive, so Iago feigns a quarrel, and finishes him off. Bianca comes by, and sees Cassio wounded; Iago makes some remark to implicate her; Cassio is carried away, and Roderigo is already dead.
