Slick was conceived as the ninth of the ten second generation Brady Patrick stories. Along with Skulk, this story was one of the few that was written in its true order, being written ninth, in addition to being ninth on the list. When I came up with the ten new ideas, they were all done within a few minutes. It was an improvised list, and because of that, Korin's story idea was written as more of a joke than a serious proposal. I hadn't originally expected to use all ten ideas - in fact, my main reason for coming up with that list was to narrow down one story to write. However, after creating the list, I was really taken by several of the ideas, and figured I could probably coast my way through the others (or change them, as I did with three).
