Man, I'm not sure about this. I LOVED what Tomasi did with the character and would've been cool with him staying dead way longer. Plus, how DID he survive that? I guess it can just be that he shot his gun in frustration that he couldn't get the "kill myself" result? I mean, we never SAW blood, right?
Hopefully Snyder keeps the fact that he knows Batman's identity in-continuity, and doesn't retcon it with brain damage or something.
