Initially, I ignored the urge to bring back KH. Why? Because I didn't want to bring it back only to not see it through to the end again. The show means a lot to me, and I didn't want to mess it around again. Eventually, I decided that we should do one final movie to wrap it up. Of course, the movie would have to ignore a lot of the cliffhangers from the series finale, but we soon worked out how to do this in a way that made narrative sense.
After working out the basic plot of the movie, along with some of the action set pieces, etc, I started to re-read the first season. By this point, I'd contacted Jon and Adam and got them back involved. Whilst reading the first season, I suddenly started to miss these characters and the setting. Suddenly, the movie didn't seem like enough...it wasn't going to satisfy my need to properly give this group of characters a send off. I wanted to tell my original story, the one that was meant to be spread over five seasons (six at a stretch!).
And suddenly I thought...why the f*ck couldn't we write a full second season, and beyond?
At that moment, Knight's Haven returned as an ongoing series.
