 Studying Othello? Here's how you can analyse the second half of Act 3, Scene 3. Othello seems taken aback. He seems doubtful and uncertain when he considers Desdemona's relationship with Cascio. Iago further fuels these doubts by reminding Othello that Desdemona did deceive her father when she eloped with Othello. Iago then uses reverse psychology to declare that he feels Cascio is a really good friend of his. However, he notices in this declarative sentence that Othello's mood has dramatically shifted. Before Iago leaves he acts concerned as he advises Othello not to give Cascio his job back as yet, to first watch him and see how he acts with Desdemona and then make a decision later as to whether he's gonna give him his job back. Once Iago leaves Othello speaks in this dramatic monologue and we can see his insecurities begin to surface. We can see that he's insecure about his race as well as his class. He doesn't feel like he's good enough for Desdemona. Desdemona and Amelia re-enter and Desdemona notices a shift in Othello. She asks these questions because you can see he has dramatically shifted in his mood. Othello confesses that he has a headache and Desdemona takes a handkerchief, one that she got as a gift from Othello with strawberries on it and she uses it to wrap it around his head. Yet these stage directions show that the handkerchief falls from his head and neither Othello nor Desdemona notice. These stage directions are arguably the dramatic turning point within the play because it's from this point that the play accelerates to being a tragedy. Amelia then picks up the handkerchief and she speaks using her pebbly to remember how Iago has been asking for this handkerchief many times. These stage directions show that Iago has re-entered and he snatches the handkerchief from Amelia. Iago gleefully decides to take this napkin and plant it where Casio lives. As Iago is considering this, the stage directions show that Othello re-enters in a rage. He speaks in these exclamatory sentences to accuse Iago of trying to make him jealous of his wife. He then challenges Iago to prove that Desdemona has not been loyal to him. Iago then proceeds to lie to Othello. He tells him that he was sleeping near Casio and he overheard Casio whilst sleeping, dream out loud about Desdemona and how they should hide their love from Othello. Iago then asks Othello about Desdemona's handkerchief, which has strawberries stitched on them. Othello reveals that this was his gift to her. Iago swears that just earlier that day he saw Casio wiping his beard with it. This leads Othello to grow filled with rage. He speaks in this exclamatory sentence as well as repetition to state that both Desdemona and Casio will pay for this. Iago then cunningly tests Othello by saying that maybe if he sleeps on it he might change his mind about Desdemona and Casio. Yet Othello uses this simile to swear that he will seek revenge against Desdemona. Othello then asks Iago to kill Casio for his betrayal. Othello then uses these exclamatory sentences as well as sibilance to vow that he will murder Desdemona himself.
