“Et tu, Bruté?- Then fall, Caesar” (III. i. 79).
Caesar
To Brutus
After Caesar is stabbed by Brutus, he sees it is his trusted friends and gives up and dies.
This shows how much Caesar really did love Brutus, and Antony uses this betrayal in his speech to turn the plebians against him.
“How many ages hence Shall this our lofty scene be acted over In states unborn and accents yet unknown!” (III. i. 115).
Cassius
To himself/ other conspirators
As they have washed their hands in Caesar’s blood he marvels at how historic this event is.
Cassius has been going after Caesar for power and glory and this proves he cannot way to be a martyr of sorts.
“What Antony shall speak, I will protest He speaks by leave and by permission, And that we are contented Caesar shall Have all true rites and lawful ceremonies. It shall advantage more than do us wrong” (III. i. 244).
Brutus
To Cassius
Cassius is worried about Antony speaking at the funeral, but Brutus says he will speak first and tell the crowd their reasons for killing Caesar. Also he will say that Antony is speaking with their permission.
This is an error of judgment by Brutus in that he gives Antony the last word. Antony eventually uses this to turn the Plebains against them.
“Caesar’s better parts Shall be crowned in Brutus!” (III. ii. 48).
Plebian
To anyone who will listen
After Brutus’s speech the Plebians fully agree with him and want him as king.
This shows just how malleable the citizens are and how they could be dangerous for a ruler.
“Through this the well-beloved Brutus stabb'd; And as he pluck'd his cursed steel away, Mark how the blood of Caesar follow'd it, As rushing out of doors, to be resolved If Brutus so unkindly knock'd, or no; For Brutus, as you know, was Caesar's angel” (III. ii. 170).
Antony
To the crowd of plebians
Before he reads the will, Antony becomes sentimental and shows how much Caesar loved Brutus.
Plebians who we know are malleable, hear this and conclude that Caesar was wronged by Brutus, who is a traitor.
