In the heated exchange between Brutus and Cassius in Act IV of Shakespeare's "Julius Caesar," Brutus expresses rage with Cassius over several issues, however, he later admits his real reason for anger is that he has just received word of his wife's suicide in Rome. On the surface, their argument is about corruption, but by the end of the scene, the two are reconciled.
The first harsh words between Brutus and Cassius are over a convicted man, Lucius Pella, whom Brutus has condemned to death for taking bribes. Cassius has publicly argued that Pella should be pardoned, which Brutus feels undermines his authority. Brutus argues that, if they were willing to kill Caesar over corruption, they cannot tolerate it among their own ranks.
The argument then shifts to Brutus' accusation that Cassius has not delivered the gold he requested to pay his soldiers. The implication is that Cassius might have stolen it. This exchange ends with Cassius offering his bare chest to be stabbed, while asserting that the money was sent and the courier must have taken it.
Finally, as the two embrace, Brutus confesses the truth about his wife. The men have a brief exchange with a poet, then they drink wine together while swearing their friendship.
