The plot of the play 'Othello' is that the Moorish soldier Othello and a young Venetian female Desdemona secretly marry. Her father isn't happy by this secret ceremony and warns Othello that if she can deceive her own father she might some day do the same to him. Iago later uses Desdemona against Othello in the play. He does this because he is jealous of Othello who became marketed to the job he seems he should have acquired. To complete this story of his, he talks many is situated and proceeds in many incidents to persuade Othello that Desdemona is being disloyal to him by having an affair with another man-Cassio.
In Act 1 World 2 Iago starts off speaking to Othello. He's trying to gain his trust by telling Othello everything he did wrong and most of his regrets. He speaks about him being with Desdemona and then he will go onto stating that he feels she is betraying him. Iago is wanting to make Othello believe Desdemona to be unfaithful to him and gives Othello images he is able to picture in his head (which in turn relates back again to when Othello saw Desdemona and Cassio dancing together). Cassio then strolls in, this makes Iago's plan go even better for him though it wasn't what he designed to occur. Cassio will come in asking Othello to visit Cyprus because the duke wish to come with an appearance from him. Iago then says that Othello cannot go because he's married. Shakespeare did this so Iago makes it look like Cassio is trying to send Othello away so he is able to be with Desdemona.
In Take action 1 Field 3, Shakespeare has revealed Iago's entire plan. He is thinking aloud therefore the whole story is discovered to us. It implies that Iago needs revenge on Othello since when he is talking with Roderigo he says: "I hate the Moor; Let us be conjunctive inside our revenge against him". Then later in the arena he shows his plan, declaring that Desdemona is the love of his life which she actually is his only weakness. So if she is made to seem to be that she is sleeping with Cassio then he'll go to Iago and tell him he was right all along and say thanks to him for realising it. If Iago's plan visited how he needed, then this might mean that out of gratefulness for realising what he couldn't see, Othello would then do anything to settle him.
