O, beware, my lord, of jealousy! What damned minutes tells he o'er, Who dotes, yet doubts; suspects, yet (strongly) loves.
I speak not yet of proof. Look to your wife; observe her well with Cassio
No Iago. I'll see before I doubt; when I doubt, prove; if proof, away at once with love or jealousy
I have a pain upon my forehead.
Your napkin is too little. Let it alone.
Why do you speak so faintly? Are you not well?
Let me bind it hard; within this hour, It will be well
This was her first remembrance from the Moor. My wayward husband hath a hundred times Wooed me to steal it.
Iago makes Othello think that Desdemona and Cassio are lovers. At first he doesn't believe him, but Othello starts to doubt his wife.
Villian, be sure thou prove my love a whore! Be sure of it. Give me the ocular proof.
'Twas my first gift
Tell me but this: Have you not sometimes seen a handkerchief spotted with strawberries in your wife's hand?
Othello goes to see Desdemona and feels that something is wrong. She tries to tie her handkerchief around his head to help his headache. Othello gets annoyed and drops the handkerchief he gave her when they first met.
Within these three days let me hear thee say that Cassio's not alive.
Now do I see 'tis true, all my fond love thus do I blow to heaven. 'Tis gone.
Emilla picks up the handkerchief and gives it to Iago...not knowing what he will do with it.
Lend me your handkerchief. Is't lost? Is't gone? Speak, is 't out o' the' way?
It is not lost, but what an if it were?
Othello can't believe Desdemona would do this. He want Iago to believe what he's claiming.
I am sure it was your wife's - did I today see Cassio wipe his beard with.
Iago plants the handkerchief in Cassio's room and uses it as proof that they are lovers. Othello believes him and wants them dead.
My friend is dead. 'Tis done at your request. But let her live.
Othello hopes it is not true and asks Desdemona for the handkerchief. Since she can't find it, he believes it is all true.
