He didn't need to understand what Huo just said, his tone voice was enough for Federico to understand that he had been disrespectful, and brats being disrespectful to older people was one of the things he hated the most. He was about to create emptiness in the trachea of Huo to leave him momentarily without being capable of breathing as a form of little punishment when the whole building trembled and Federico dropped his cigarette. Then the girl said something he couldn't understand, but with much nicer tone

"Name is Federico. Dile a tu amigo que respete a sus mayores o no durara mucho en el mundo real, independientemente de sus poderes." (Tell your friend to respect his elders or he won't last long in the world, regardless of his powers)
