Let me have men about me that are fat, sleek-headed men and such as sleep a-nights. Yond Cassius has a lean and hungry look, he thinks too much: such men are dangerous.
Would he were fatter! But I fear him not. Yet if my name were liable to fear I do not know the man I should fear I do not know the man I should avoid so soon as that spare Cassius.
Fear him not, Caesar, he's not dangerous, he is a noble Roman and well given.
Was the crown offered him thrice?
Tell us the manner of it, gentle Casca.
Ay, marry, was't and he put it by thrice, every time gentler than other; and at every putting-by mine honest neighbours shouted.
I can be hanged to tell the manner of it...for he swounded and fell down at it. And for mine own part I durst not laugh for fear of opening my lips and receiving bad air .
In the first scene, Caeser speaks to Marc Antony to express his concerns about Cassius. Marc Antony tries to ease his fears, but Caesar still distrusts and dislikes Cassius.
In this scene, Brutus (alongside Cassius) pulls aside Casca and questions him about what happened during the games. Casca then explains hat Caesar had a seizure.
So is he now in execution of any bold or noble enterprise, however he puts on this tardy form. This rudeness is a sauce to his good wit, which gives men stomach to digest his words with better appetite.
I will do so. Till then, think of the world.
What a blunt fellow is this grown to be! He was quick mettle when he went to school.
And so it is. For this time, I will leave you. Tomorrow if you please to speak with me, I will come home to you; or if you will, come home to me and I will wait for you.
Well, Brutus, thou art noble; yet I see thy honourable metal may be wrought from that it is dispos'd. Therefore it is meet that noble minds keep ever with their likes; for who so firm that cannot be seduc'd? Caesar doth bear me hard, but he loves Brutus. If I were Brutus now and he were Cassius, he should not humour me.
I will this night, in several hands, in at his windows throw, as if they came from several citizens, writings, all tending to the great opinion that Rome holds of his name, wherein obscurely Caesar's ambition shall be glanced at. And after this let Caesar seat him sure, for we will shake him, or worse days endure.
Cassius and Brutus converse in the third scene. They reference a former conversation they had in which Cassius attempts to persuade Brutus to turn on Caesar. Brutus' response foreshadows a future conversation and tells that he is open to the idea of this plan.
The final scene is of Cassius speaking in soliloquy form. After noting that he sees how Brutus may be willing to turn against Caesar, he tells of his plan to throw letters into Brutus' window that complimented him, pretending they were from citizens.
