Brutus and Cassius exchange accusations in Brutus’s tent. They grow angry with each other but are quickly reconciled, and Brutus tells Cassius of Portia’s death. With Titinius and Messala they plot their military strategy. Brutus overrides Cassius’s objections and insists that they march to Philippi to challenge Mark Antony and Octavius. As Brutus reads in his tent after the meeting, he is visited by the Ghost of Caesar, who threatens to visit Brutus again at Philippi.
