Throughout the play, Iago uses Emilia's close friendship with Desdemona to gain access to her and, in particular, asks her to steal Desdemona's handkerchief, which he subsequently drops in Cassio's house and later uses this as evidence to convince Othello that Cassio has been with Desdemona. Emilia does not agree to steal the handkerchief for Iago. Iago snatches it from her and all she can do is ask about what he will do with it (III.iii.310–320). Iago is the one who drops the handkerchief in Cassio's chamber. (III.iii.321–322). Later Emilia even lies to Desdemona, saying she doesn't know where it is; it is clear she feels a "divided duty" in this matter between her friend and her husband. She is, however, entirely ignorant of Iago's plans until the very end of the play.
