It was time for Jason to meet up with Allison, Jason now knew that Allison had a direct hand in what had transpired a couple of months back.
Jason didn't know who Allison was, there was no way that she could be this evil.
Jason knew that she was a threat he had to take care of or she could potentially put the entire community at risk.
He went unarmed because something told him that Allison wouldn't be alone but she had no reason to suspect him of anything.
He wasn't sure she was alone and assumed that she would come with one or two of her guards to frisk him.
Jason was prepared and the last thing he needed was to have her on guard, he had Chronos and if he needed to, he could fight his way out of the situation.
He had his system after all even though the system was slowly losing its function as one due to Jason slowly gaining full control over it hence bypassing the mechanics put in place.
