When Oliver, Kei, and Niki saw what Alex did, it made their jaws drop. Yet after awhile Oliver got super excited at what he saw. Someone his age got to become so strong, that would mean he too had the possibility to become just as strong or even stronger.
Kei on the other hand couldn't comprehend what had happened. Was Alex some sort of superhuman? Was he an alien or something? A cyborg perhaps? Or does this incredible strength of his is attributed to the martial art he was learning.
Niki on the other hand just kept on convincing herself that her nii-nii was better, stronger, and cooler than Alex.
When Alex noticed what he had done, he immediately called his dad. Which made him a bit irritated, cause ever since he came back, he kept on calling his dad to fix something he did.
Carlo picked up the phone, and without waiting for Alex to say anything he spoke.
