Just as Madara's about to take off his mask, Sasuke's eyes perform Amaterasu.
Shocked at the sudden ocurrence, Sasuke presses his eyes and moans in pain.
Madara explains to Sasuke that Itachi implanted [the Amaterasu mechanism] in his eyes at the very end of the battle to keep Madara away from him.

Sasuke's dumbfounded, and demands to know what Madara means. To this, Madara replies "it was to protect you," "you know nothing about your brother."

Surprised, Sasuke becoms agitated. Madara declares he will now tell Sasuke who Itachi was and how he lived.

And next week, there will be no Naruto.
