In all honesty Zero had no desire to remain there at all; hell his instincts were still screaming at him to kill her, find the boy, and get back home. However when JJ pulled out the phone and suddenly presented the man with a photo of them together...those eyes of his just went wide. Up until this moment he had no reason to believe a damn thing she said. Yet now, now he found himself looking at an image of himself and her. A part of him was still so very wary; granted being kidnapped did tend to have that effect on a person, but the tension also slowly started to melt from his shoulders as well.
"Two days...that's, you've got two days." Uncertain and so very confused Zero found himself agreeing to her request. All on the long shot that somehow in two days he'd finally get the answers he had been seeking for three long years.
