Well, it was almost the inevitable result of developing the property from scratch.

We weren't going to do a period piece. Not that that might not be interesting, but I doubt it would have sold. Everyone wanted it to feel up-to-the-minute and contemporary.

And we were doing a show about the young teen heroes, which meant the adults had to be already established.

And we even wanted a handful (Robin, Speedy, Aqualad, Kid Flash) of the teens to already be a little established.

Beyond that, I just did the math.
