Rather than being overwhelmed with emotion by her death, Brutus controls his emotions in typical stoic fashion and continues planning his military strategy against Octavius.
In Act 4, Scene 3 from Shakespeare's "Julius Caesar," Messala informs Brutus about his wife's death. However, instead of exhibiting extreme oppression, he expresses that he can deal with it because he has already considered she would die one day. Finally, he moves on to organize an armed strategy against Octavius.
