Explosives would have been bad - although loud battle cries aren't much better. Or piercing screams, come to think of it. Jamie's head whipped up at that sound, and the zombie that was trying to claw his face off decided that meant that he could try and rip Jamie's throat out instead. It very nearly succeeded, and the Scot only managed to save himself by quite literally flinging himself backward and just out of reach.

Luckily, his reflexes were quick and the follow-up swing of the sword landed the blow needed to take care of the zombie for good. The poor waitress Jamie left behind for now - she wasn't exactly going to be able to run after him in her condition and he had the feeling that the longer he waited, the worse it would be for whoever had screamed. He was pretty sure that was Ichijou, just by process of elimination. But if these undead things had gotten in, someone else might have gotten in as well, and no matter who it was they needed to be helped.

As he ran down the corridor towards the noise, he only hoped he wasn't too late.
