“There was a man curled up in the corner, trying to hide himself behind a bowler hat and not succeeding very well. He had a little bit of ink on his hands, but wasn’t nearly as grubby as the other men. I went over and asked him if he was all right. He started muttering ‘I must obey, I must obey’. Very zombie. The Doctor asked him who he must obey, and he said ‘the Queen’. Which the Doctor said was an admirable sentiment, but what did the Queen want him to do? And he said, ‘kill’, which I didn’t think was very admirable at all.”
