Billy & Tawny was born of a lot of things; most obviously, it's a love letter to Calvin & Hobbes, and to the Captain Marvel/Shazam mythology. Calvin & Hobbes was very formative for me (hardly a unique sentiment for anyone of my generation) and I've always thought the Shazam franchise had the potential to be so much more than what it was. But really, this was my first attempt at hyper compressed, one page stories. It's a hoary old piece of wisdom that writers should try their hand at short stories to establish and refine the basics,  and I thought a series of 1 pagers would be a good exercise. I found it was some of the most fun I've had writing, and have many more Billy & Tawny scripts waiting in the wings, should the opportunity and interest arise.
