Half an hour after Kai's call, Zac left the subway station closest to his house and went to his and Amy's apartment.
He was nervous, of course. As capable as he was right now, he wasn't a 'superman' who could guarantee Amy's situation or even protect himself effectively against bullets. He had his methods to defend himself, but he wasn't invincible. In this manner, his heart couldn't help but thump louder as he made his way back home.
In his mind, he kept thinking about how his enemies would probably use his sister in some kind of blackmail against him.
He planned nothing at first. As he saw the facade of his building, he walked down the deserted street into the early evening. He just wanted to settle his affairs as soon as possible.
