Desdemona, still actively seeking to have Cassio reinstated, is worried about the loss of her handkerchief. Her anxiety about it increases when Othello asks her for it and then sternly rebukes her when she cannot produce it. Cassio approaches her, but she must now, because of Othello’s anger, postpone her efforts on his behalf. As he waits, Bianca, his lover, appears. Cassio has found Desdemona’s handkerchief in his room (placed there by Iago) and he asks Bianca to copy the embroidery work for him.
