Again, they say everything matters, and everything happened. Buuuuut, then, explain to me:
How could it be that Superman and Diana were involved in a long-term relationship (one where he was apparently ready to propose to her) but at the same time Superman was married to Lois with a child at home?
Also, how would it be possible that New 52 Superman's origin with his parents dead is still intact when we see, quite clearly, that his parents are still alive currently?
How could the New 52 storyline "Truth" still have happened? In that story, Lois Lane revealed to the entire world that Clark Kent was Superman, so how was Superman's secret identity secret again post-Superman Reborn and was only recently revealed again during Bendis's run?
If the New 52 Amazons still existed in this timeline, then why do we have a Hippolyta who is definitely NOT the New 52 Hippolyta serving on the JLA right now?
Also, how can it be that the Amazons of Bana Mighdall are back when they were erased by Flashpoint? Also, then what was the whole Greg Rucka Rebirth run about, with the whole "Lies" storyline?
How could the New 52 Justice League origin still be how Victor became Cyborg, yet the preview from Deathstroke, Inc. shows that the New Teen Titans and his old origin are now intact?
These are contradictions that can't exist in the same timeline. That's all I'm saying.
