Any chance that when Mr. OZ first showed up being written by Geoff Johns, that he had a different idea in mind for the character's true identity? Or do you think it was his intention (or the editor's) to reveal him to be Jor-El the whole time?
I think it was like 4 years or something like that between Mr. Oz's first appearance in Superman, and being revealed as Jor-El in Action Comics right before Bendis took the helm.
