"What sense had I in her stol'n hours of lust? I saw 't not, thought it not, it harmed not me. I slept the next night well, fed well was free and merry..." (Act III.iii.346-348)
"I am sorry to hear this." (Act III.iii.352)
"No, as I am a Christian If to preserve this vessel for my lord From any other foul unlawful touch Be not to be a strumpet, I am none." (Act IV. ii. 88-91)
So you’re saying you’re not a whore? (Act IV.ii.92)

This dialogue between Iago and Othello portrays Othello's external conflict which illustrates person vs. person conflict (Desdemona vs. Othello conflict) since Othello is very mad at Desdemona "cheating" on him and then pretending to be a very dedicated and faithful wife...It also shows how Iago gained Othello's trust and is able to manipulate him and make him believe that Desdemona is actually "cheating" on him with Cassio. This makes Othello lose his trust toward Desdemona and gain towards Iago. In addition, this dialogue also shows that Iago's plan is succeeding since it is evident that he made Othello very suspicious and angry at his wife and thus Iago pretends to be "harmless" and "sorry" for what has happened. Once again, connecting to Othello and his dialogue with Iago this external conflict propels (person vs. person) the plot of the drama and the importance of this scene because Iago sets up the future conflict between Desdemona and Othello as it is visible that he is in range with her and considers her a disloyal and dishonest wife. Therefore, this conflict foreshadows that jealousy towards Desdemona and revenge towards Cassio will blind Othello from seeing the truth.
This intense dialogue (conflict/fight) between Desdemona and Othello shows external conflict, person vs. person conflict or Desdemona vs. Othello conflict. In addition, here the reader can see that Iago has greatly convinced Othello to believe him and what he says, that now Othello's revenge and jealousy towards Desdemona makes Othello accuse her of doing something she never did or thought of doing (being a "whore"). His ignorance makes him not trust Desdemona and her pure faithfulness, loyalty, and love. Othello insults Desdemona by calling her a "whore". However, she still tries to figure out the reasons he might think of that and tries her best to prove herself an innocent wife. But Othello's trust towards Iago makes Othello only believe him and ignore Desdemona and her reasons for denying what Othello said...This conflict also propels the plot of the drama since Desdemona's and Othello's conflict and misunderstanding are only growing worse. And the reader gets to see how it provokes Othello's decision to trust Iago, order Iago to kill Cassio, and express his disappointment and hater towards Desdemona. Hence, this conflict/scene is significant to the drama because here the reader can see and is able to predict that Othello's love for Desdemona has faded and all he wants is to prove to her that she did the wrong thing when "cheating" on him with Cassio and betraying him. Therefore, he orders Iago to kill Cassio.
In this scene, Othello has an internal conflict which is person vs. self. (Othello vs. himself conflict). Because when Iago told him of what he saw happening between Desdemona and Cassio he leaves Othello on his own with his thoughts. He wants the thought of Desdemona "cheating" on him to be flowing in his mind over and over, torturing him and make him doubt everything about her, which illustrates that as Othello's love towards her starts to fade his internal conflict grows deeper. He starts wondering about Iago's words and thoughts... And finally thinks that he committed a big mistake when marrying Desdemona. Othello gets very jealous and revengeful after a talk with Iago. He believes that Iago is a very honest and friendly man, thus, gives all his trust to him. As if he went "blind" and could only see and believe what Iago tells him...This internal conflict foreshadows Othello's insecurity that Iago has almost discovered in order to succeed in his evil plan. (Othello has low self-esteem and starts criticizing himself to reason as to why Desdemona would be disloyal and unfaithful towards him.) Thus, this propels the plot of the drama by foreshadowing how Othello could not think of many reasons for Desdemona's true love towards him and therefore he allows his jealousy and insecurity to torture his life. (This reveals aspects of his character which propels the drama).
