As the man attacked Jack growled. "I'm not dying yet, bruv." When he grabbed his gun, he let go of it, and dropped low, performing a sweeping kick, aiming to knock the man off his feet. Without looking for a result, he backed away slowly, in a fighting stance. "Listen, man. I had to assess you." He said. "Whoever doesn't introduce themselves at gunpoint isn't trustworthy." A grin spread across his face, and he moved closer before he stuck out his hand. "Jack Oakson. You?" He was relying on his test now. His cloak had dried infecteds' blood on it, most likely to try and deter them a bit. His hand was still stuck out. "Don't leave me hanging, mate." His smile was genuine and friendly.
