The identity of the traitor who leaked information to Fango and tried to kill Nero has been revealed. With Corteo taken into custody, the Vanetti family has been thrown into an uproar. But Corteo stubbornly refuses to confess anything, a fact which will likely lead to his death. Though he won't admit to it, Avilio is unusually shaken by this. And then Cerotto pays him a visit...
In back! He escaped out the window!
!في الخلف! هرب من النّافذة
Hinten! Er ist aus
dem Fenster gestiegen!
¡Escapó por la ventana!
¡Se ha escapado por la ventana!
Derrière, 
il s’est enfui par la fenêtre !
Pelos fundos! Fugiu pela janela!
