I don't know either, some Batman that came from hell and was part of a league of impostor Batmen. Batman got shot and went into cardiac arrest. Gordon got shot too.
Spoilers.
A Batman that came from hell? WTF?
Dear, sweet Harley Kwink...I'm madly in love with you. Marry me! We can go to Canadia. Or Boston or something. It'll be grand...You know the cookies are a given. They are ALWAYS a given. You could dump me tomorrow and you'd still get the cookies. Boston..shit, wherever dyke weddings were legalized. And where better to rub their little piggie noses in how bad they suck than right on their doorstep? What are they gonna do? Be jealous of you? Stare furiously at your tah-tahs? Not willingly give you cookies, but instead begrudgingly give you their cookies? Woman, time to wake up to the powers you wield - Uschi
