Bruce will never learn, is kind of the way I see it. He's regressed, even, since a couple of writers got hold (a hold?) of him. Maybe this 'dying' thing will make him wiser, but I even doubt that.
Maybe he keeps a little three by five cards in his utility belt full of memos to himself. My husband does. Not, you know in a utility belt, but I mean that's why I have a cute but tiny notebook in my purse. Same thing. Come on, Batman. Keep track of your 'fantastical experience' lessons. I'd think he would. WGD and all.
Hang on. Forget I said that. Until I finish the story of what Batman's little purse utility belt notebook reminds him.
