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 his name.
I have made a strong proof of my constancy, giving myself a voluntary wound here, in the thigh: can I bear that w/ patience, and not my husband's secrets?
This is one of the first events of the play that indicates the reader that something horrible is going to happen to Julius Caesar. In (1.2.23-24) the Soothsayer warns Caesar that something bad is going to happen to him in the middle of March. Caesar brushes this warning off and acts like the man is crazy and continues about his day. This is also the first example of Caesar's ignorance that auspicious events are meaningless.
Caesar, I never stood on ceremonies, Yet no they frighten me. Recounts most horrid sights seen by the watch
What can be avoided whose end is purpos'd by the mighty gods?
We see how cunning Cassius truly is when he formulates the plan to get Brutus on the Conspirators. In (1.2.305-312) Cassius creates a plan by writing multiple fake letters asking for Brutus to be king from citizens that don't exist. Cassius goes into detail by changing up the handwriting in each letter to make it look more realistic. Cassius' letters will contain complains of citizens not wanting JC as king but instead Brutus himself
LIBERTY! FREEDOM! TYRANNY IS DEAD!
Et tu, Brute? Then fall Caesar!
One of the most extreme acts of loyalty is demonstrated through Portia stabbing herself in the leg. In (2.1.299-303) Portia is dying to know what is bothering Brutus so much that she is unable to sleep. She feels that trust has been lost in the relationship and stabs herself to show her loyalty to Brutus that she is trustworthy. Brutus sees this and understands how important he is to his wife and tells her the secret.
We will be revenged
O woe day!
O traitors! Villains!
Calpurnia has been recently getting nightmares of JC dying and seeing very ominous events take place in Rome. In (2.2.13-25) shows how much she loves JC and begging him to stay home away from the possible danger. Her dreams worries JC of his safety and Calpurnia's and decides to stay home. After a while he later realizes that he doesn't believe in omens and decides to go outside thanks to his ego getting in the way w/ the help of Decius changing the meaning of the dream.
When Caesar is killed by the Conspirators is the climax of the play. In (3.1.77) Caesar is in his last seconds of life and sees Brutus stabbing and he feels absolutely betrayed because he thought he was his friend. He then realizes that if Brutus killed him then he's death has a purpose for Rome and accepts his death. Cinna rejoices in seeing JC dying painfully believing that the new ruler of Rome will be better.
After the Plebeians find out the truth of the conspirators Antony they want to avenge Caesar's.

They are motivated to riot from Antony's speech and realize how much JC loved the citizens b/c he gave them 75 drachmas each and land. The Plebs are absolutely heartbroken by the way they spoke about JC and want forgiveness for being so fickle.
