I was writing a chapter about President Crowdler, where he is told that the escapees have been recaptured. I needed a name for the person telling him, and Johnson was the first name I thought of. Thus, Johnson entered The Experiment. He had other tasks; he became the chauffeur, he tried to be a bodyguard, and most of all, he was there for the President to order around. Johnson doesn't have many scenes, but he's all I could think of for "J," since I had to put Jen with York in order to avoid repeating information. I do kind of feel sorry for Johnson, since he is under the President's control, but . . . I must say no more. I can't give away the ending of the book.
As a supplement to Johnson, here's a link to my latest interview, on KingdomTales.org.
