Re: DC's New 52: Reviews and Discussion (Spoilers welcolme and likely)
As much as I don't want them to kill of Alfred, this story cannot end without serious consequences. Bruce has to pay a price for his arrogance, and unwillingness to see the truth. Killing Alfred seems the most likely possibility, since obviously everyone else has their own monthly titles. In this scenario, Harper most likely becomes the "new Alfred" so to speak.
