Bear with me, because there may be a lot of New 52 continuity that I just didn't pay attention to.
When New 52 launched, there was much consternation amongst fans about, "How does this work?" "How did this happen, in-universe?" "What's the timeline now?" "What do characters remember?" etc
At the time, fanboys (and girls) could get excited about the 52 appearances of that mysterious female, because therein lay the promise of some grand EXPLANATIONS! The clear implication was that this woman was someone involved in the continuity-altering event, and that her involvement would be revisited at some point.
To my knowledge, it never really was? She turned out to be a totally meaningless and irrelevant character?
So, anyway, now with rebirth, I'm seeing some of the same questions, and some of the same fanboy/girl anticipation that The Watchmen Event, when it eventually comes, will explain EVERYTHING.
Will it? Will the Watchmen even appear again? Will Dr. Manhattan's apparent role in "causing" the relaunch ever be explored to anyone's satisfaction? Or is it just misdirection to keep the fans from griping too much right now? In a few years when everyone's accepted the new continuity, will we all just sort of recall, "Oh, yeah, whatever happened to..."
