Hey, you'd know more than me! I don't know what would be a big moment for fans since I only started getting into Batman recently—jumping through random trades from the 30s to modern times. That does not work for Grant Morrison Batman!
I actually didn't even think this was a big deal, but I don't know Batman's continuity like I do Spider-man's. Well, the stuff from 1962-2007. I dropped off because it wasn't my cup of tea after that point.
