A girl had pointed a weapon at him. Pyro didn't like people pointing weapons at him. Had he been a rational, calm thinking man, he might've tried to be diplomatic and do hand gestures. But no. Pyro was a pyromaniac, schizophrenic and delusional pyromaniac. Did I mention he was a pyromaniac?

So he did the second best thing...He plopped himself on the ground, took out two sausages from god knows where and started cooking them with his flamethrower. Once done, he pointed to the girl and the schoolboy. Then to the cooked(burnt) sausage.
