Othello 1.1

In Othello Scene 1, Shakespeare introduces 3 characters, none of which is Othello. They are Iago, the flag holder for the army of Othello, Roderigo, a friend of Iago, and Brabantio a senator of Venice and father of a woman interested in Othello. The scene starts off with Iago complaining to Roderigo about Othello choosing Michael Cassio as his officer and second-in-command. Iago argues that Michael doesn't have any experience as a soldier but Iago has been a witness to Othello's acts at many different battlefields. Roderick questions his loyalty for Othello and Iago responds saying that he is following Othello for his own sake and not for love or duty to Othello. Right after, they arrive at Brabantio's house tell him that his daughter is with Othello. Roderigo then convinces Brabantio to check for his daughter who is not there. The scene ends with Iago returning to Othello and Brabantio leaving to look for his daughter with Roderigo.

Reading this scene for the first time, to be honest, was really confusing. Aside from the language, the characters were really unique. Iago seems to be a loyal follower of Othello but in reality, he is pretty jealous and narcissistic. Also, Brabantio is a senator but his actions after finding out that his daughter left, are anything but senator-like. The character development is very detailed and deliberate right from the start of the play

What evidence can you find in this scene of Iago’s manipulative nature; narcissistic personality; jealousy?
Iago's manipulative nature is shown in his actions with Brabantio's daughter. In order to get Othello in trouble, he goes to tell Brabantio that his daughter is sleeping with Othello. His narcissism and jealousy are shown when he complains about Michael Cassio being Othello's aid and he believes that he is much more capable.
