As Diego stared at himself at the mirror after taking his bath, when the wound of his busted lips which was given to him by Giovanni, came in line of his vision, a hiss left his lips when he touched it, and he couldn't help but imagine his mother not walking in on them, he had a very huge comeback for him, one that would scare the living hell out of him.

Diego couldn't wait to see the reaction on his grandfather's face, when he gets to realize that his precious grandson was the one who wants to bring him down, not only would it shock the old man, he prayed that gets a heart attack, but until then, he would continue to play a fool as if he doesn't know that Giovanni was about to fall into his trap.
