Act 3 othello

Man i think things are getting way more interesting and am getting more and more into it. Its like now this whole the is playing out in Iago way. He has been setting up his plot and now it seems like he is really to see it all play out. The whole thing with the handerchief is like a master mind type plan I think Cassio is so blinded and not thinking about where he got the handerchief from in the first place then nobody wanted me having this problem.
