Really enjoying Young Justice so far!
1. One of the things I like most about the show is the attention to detail you've given to the characters and the world. How exactly did you plan out which characters/locations(even peripheral ones) you were going to use for the show? Was it something where you made a list of people/places you wanted to use and how they relate to one another prior to the beginning of production in a "series bible" or does it grow and change from episode to episode?
2. Seeing as how Superman is apparently the first superhero in this universe and has only been active for about 10 years at the start of the series where does that put groups like the JSA or heroes such as Spy Smasher or the Crimson Avenger?
