John:

John finds nothing in the abandoned gas station worth scavenging, nor any living creatures. So he quickly sets out in the direction of the shots and the screams. As he cautiously peers around the corner of the first street he comes to he sees a handful of people in the distance who don't seem to be acting as infected do. He scans the area for any other threats before continuing towards them as quietly as possible. Maybe they'll have some information that's useful, but I had better not yell at them from here, I need to cover some of this ground first. He heads towards the group as fast as he can while moving as quietly as possible, but if they look his way he will try to get their attention silently.
