 I was told to kill zombies, take no chances. How were you told? What were the words? You can hear the command now. What is it, Captain? What is it? Kill all zombies after they've killed. Kill all captured zombies. Forget you were told this. It's almost as though a woman were talking. You can't always be sure, Mr. Thurston. I can't remember anything. He's been given a lot of commands to forget. It's going to take quite a lot of work to get it out of him.
