But I'm Cinna the poet, not Cinna the conspirator!!!!!!!
Brutus has been gone for so long, I must eat fire and die.
Portia! What are you doing? Are you insane?
After the crowd gets angry at Antony's speech, they go away carrying Caesar's body. They come upon a man named Cinna. They ask him what his name is and when they hear that he is Cinna, they assume he is a conspirator and try to kill him.
After Brutus had been gone so long, Portia eats fire and kills herself. It seems like Brutus has been gone since the scene where she stabbed her leg to prove how dedicated she was to him.
