When I Say Run...
The Infected man howled, and the high-pitched scream alerted more. They began to run, swarming at high speed through the deserted streets of an empty London, all converging on the same target - the small man with the umbrella and bitter memories of ruined cities and patrolling monsters.
The Doctor took in the man's burning red eyes, savage expression, blood-encrusted mouth. He swallowed nervously and backed away.
"You wouldn't rather have a jelly baby, would you? So much better than flesh, I tend to find."
The Infected man howled again. The Doctor ran. The Infected ran after him.
