Like a trapped rat, the doctor would scurry from one military vehicle to another or a civilian vehicle if possible. It was a few hours that past and he used the radio again to hear a human voice. 

" Last calling station, hello, hello?" He tried several times and even changed then battery after a half hour.. but then realized that it was running on the vehicle battery. When the dead wold come he would throw things or try to break a hit from afar. It was morning when we would run the vehicle for a bit then shut it off, then scurry, left piles of things that he wanted to get later because those things were everywhere. Like cat and mouse... but he was the mouse. The doctor must have gotten sloppy because coming around a vehicle he ran into a woman that he thought was alive at first and spoke to it. As the creature turned, the doctor dropped his stolen goods and lifted his crowbar as he beat it. With every hit he was crying and yelling " I'm sorry". 

That was a bad night... he didn't leave, eat or drink anything till the next morning.
