That has, annoyingly, not been revealed. My understanding, at this point, is that it was self induced.
But the Snyder Batman stuff isn't doing it for me at all. I'm not even sure why, to be honest. I was loving Court of Owls, until the 'big reveal'.
I think my biggest issue with it is that it feels like he's employing really lazy 'detective story' themes...where he's writing glaring clues, to the point where you're able to sort it as soon as he drops it. It feels formulaic now.
That said, the Zero Year story so far has been fun. I'm liking it so far.
My primary enjoyment from Bat books is coming from Red Hood and Batgirl right now though. Simone is laying on the morality plays thick, and I'm loving it! Jason, and his new 'Dark Crystal' origins have been a full treat to read since day one. I kinda hope he stays where he is right now. The current arc is brilliant!
