Othello Help? I need some quotations of went Iago plants the thoughts of jealousy into Othello. I am trying to find some and can’t find an exact quotation. Is this right? Iago: “Did Michael Cassio, when you wooed my lady, Know of your love?” or Iago: “I did not think he had been acquainted with her”
