Mauro is possessed by a huge number of Empty Shadows. They twist his mind, causing him to became an enemy of mankind. Hiro and Luca fight to bring him back.
So you don't care 
whether everyone disappears?

todo el mundo desaparezca?
Non ti importa se tutti quanti scompaiono?
Então, não se importa
se todo mundo desaparecer?
