Two little details: SPOILERS ABOUND!
First, I love seeing Batman's eye and his smirk near the end when he says, "I'm headed to the potter's field...courtesy of the mud on your truck."
Second, so in Nightwing #30 (effectively, the first issue of Grayson), we're really meant to take as important Leslie's inability to remember whether she revealed Batman's identity as Bruce Wayne? Because she doesn't mention it here at all, and there seems to be no such burden in their relationship with each other (which I found really moving here).
