Act 4, Scene 2

Brutus is with his army in the field. He asks Lucilius how his meeting with Cassius went, and is dismayed to learn that Cassius seemed to be acting coldly. Cassius arrives, and Brutus asks to speak privately. Cassius complains about Brutus disciplining one of Cassius’ subordinates, and Brutus in turn accuses Cassius of taking bribes. Brutus argues that they must wage war honorably, or the killing of Caesar was hypocritical. Cassius contends that a practical approach is the only way to win the war.
