Antony meets with Octavius and Lepidus to review a list of names and determine which conspirators they should kill. Lepidus is sent out to fetch Caesar's will to see if they could redirect funds to their cause. Comparing Lepidus to his horse, Antony sees him as an errand boy to the greater plot at hand.
"You may do as you will; but he is a tried and valiant soldier"(Caesar, 27-28)
"So is my horse, Octavius!"(Caesar, 29)
Act IV, Scene 1
Brutus is waiting at camp when Cassius arrives, scolding Brutus for having wronged him. Brutus tells him that he would not wrong him, that they were brothers, and should take their disagreement into Brutus' own tent. This was a means for them to keep friendly appearances in public.
"Most noble brother, you have done me wrong." (Caesar, 37)
"Judge me, you gods. How should I wrong a brother?" (Caesar, 38-39)
Act IV, Scene 2
Cassius and Brutus quarrel about the acceptance of bribes, Brutus arguing that they were no worse than what they proclaimed Caesar to be (being a corrupt person). The two men insult one another and quickly, Cassius accuses Brutus of no longer loving him.
"Just for supporting robbers, shall we contaminate our fingers with base bribes?"(Caesar, 75-76)
"Brutus, bait not me, I'll not endure it." (Caesar, 80-81)
"I did not think you could be so angry." (Caesar, 195)
Cassius offers Brutus a dagger to slay him, but Brutus refuses to kill him, saying that they are both ill tempered. The two have a wine and express what the root of their sorrows are: for Cassius, his temper stems from his mother; for Brutus, it comes from recent news that his wife, Portia, had committed suicide. Cassius later departs for the night after discussing a plan to meet their enemies in Philippi.
"O Cassius, I am sick of many griefs." (Caesar, 196)
Brutus is interrupted from his reading by a specter, who startles him. He asks who the ghost is, to which it replies "thy evil spirit." It tells Brutus that they will meet in Philippi, then promptly disappears.
"Speak to me what thou art." (Caesar, 333)
"Thy evil spirit, Brutus." (Caesar, 334)
Brutus was convinced the ghost was a sign of what would come of the meeting in Philippi. He goes out to his attendants to ask if they saw anything strange, only for them to response that they saw nothing amiss.
