How Does His Brain Work?

Grey soon appeared close to Alec, he was already out of the Fusion State, so he was back to the Third stage of the Sage Plane. 

Alec stared at him for some time as if he was a monster, technically, he did see him as one. Just like Grey, he was also in the Third stage of the Sage Plane, however, Grey managed to fight against multiple Peak Sage Plane experts on his own, he didn't even dare to call himself a genius in front of Grey. 

"You're here, unharmed." He said while examining Grey.

"Yeah, it was quite a hassle, but I managed to escape." Grey replied casually. 

Alec knew for a fact that Grey didn't 'manage' to escape, he left after causing massive destruction to the city. From the explosion he saw, half of the city is most likely destroyed by that attack. 

The experts wouldn't want to cause such damage to their city, so Grey was the only person that came to mind.
