Andrew is the nice footman. Because Conrad's education as a lackey at Stallery Manor is to cover every key male service position enroute to becoming a gentleman's gentleman (that is, if he succeeds in improving himself to the point of being chosen), he often has to do things under supervision of one of the footmen. He can enter and leave rooms in an absolutely silent fashion, behave like living furniture at the side of a room until needed, and serve food or beverages smoothly and efficiently. And Andrew is a decent chap. Which is more than could be said for some footmen I could mention. Yes, I'm talking to you, Gregor.
