Leon is an anomaly. Technically, he is a canon character. Hamilton speaks to him over the intercom at least twice in season 2. In addition, a male voice speaks over Hamilton's intercom in a couple of season 1 episodes, and that is probably meant to be Leon even though no name is used. But we never see him. Everything about him other than his name and the fact that he works for Hamilton is of my own creation.
