Handkerchief

My plan is all coming together nicely. With one last scheme in place and complete, I can step back and watch the chaos go. What scheme am I referring to? The handkerchief. Yes, I was the one who planted it in Cassio's room. I knew it was Desdemona's and by putting her property in Cassio's room is like putting her in the room. The fact that Othello gave her the handkerchief that was his mothers and for the reasons he did just make this all the better. Desdemona comes off, not only as a subtle whore, but as not caring about Othello at all. If she placed and ounce of value in the handkerchief that Othello did then she wouldn't have been so careless to leave it  in her new lover's room.

With this new diabolical twist in place, all I need to do is continue to secure my innocence. I must just keep reassuring Othello and drive his thoughts of her betrayal home. I must further prove my loyalty by staying by his side. He is already convinced and now he will have no doubt to fall back on with this physical evidence.

Placing her in Cassio's bedroom...BRILLIANT!
