Ha. I suspected Azzarello talking about Steve Trevor appearing in the book was just a joke Azzarello made while Didio was present. I think that's why Steve is getting developed in the JL book, and Etta too-- Johns wanted the basics present in Diana's status quo, even if Azzarello is ignoring it.
Seems like the goddesses will start appearing, "soon." Interesting note about Diana's 4th sponsor. Who is it? (and who's the third? Ares? Hera?)
