Jason pointed the gun toward he head and pulled the trigger, only to find it jam. He never really bothered to clean the rusty old thing. After shooting a few times, jason grows angry, and he threw they gun at the young lady, missing abruptly. He looked at the girl as she seemed angry, wish she deserved to be, he coward as he looked at him, without him crowbar or pistol, he was useless against a girl, stabbing one was different, you needed to get up close or make the cut wide and jason couldn't bring himself to do something like that. He was also a skill combatant and was trained in many styles, but again he felt wrong to attack a woman, maybe he was more gentlemanly that he remembered, maybe the zombies hadn't taken that from him.
