Last year, while working on "Thanksgiving", at the same time I was writing a fourth episode: "World of Krypton I". This was going to be an adaptation of John Byrne's World of Krypton, the first part of a 2/3-part arc exploring Krypton's backstory. Since then, I've decided I want to ground this series more, to hew closer to the Siegel & Shuster stories, with an emphasis on class struggle rather than sci-fi scenarios, so I'm nixing this storyline.
For anyone interested in reading the unfinished "World of Krypton I", here's the link:
