Where has Batman been?

That’s the question. And yes of course like Batman said, “I can’t be everywhere” but he had to be doing something he deemed more pressing than to intervene in the events of the Penguin series. In the end of the series we see his bat signal, most likely signaling him starting to learn about the Penguin and the things that happened…but that still begs the question, where was he? If you were Reeves how would you explain his absence? You could say he has been working on his Bruce Wayne persona more, but he still has to be Batman. And whatever he was dealing with during the events of the penguin was more pressing to Batman at that time at least. Was he dealing with the new big bad of part 2? Was he simply just resting? Thoughts?
