That's just the last page though, this book has a lot of fun stuff hitting before that. The high point has got to be Nightwing finally beating Deathstroke. I'm not sure Nightbats has ever fought him and won, and I suppose this wasn't an actual one-on-one situation (since Deathstroke was controlling Damian) but this has got to be close. Combine that with Nightbats strolling in and walloping Deathstroke while he's recuperating and this is a pleasant little issue. I'm also quite intrigued that Damian is going to leave his mother and truly sign in to join the Bat-family. I'm not sure they want him, but there is no doubt he's a fun member of the group now.
And how about Talia building herself another cloned son? How long before we have a new evil Damian-type on the other side? It should be pretty interesting seeing the two "sons" of Batman facing off over the next few years.
There are some clues for Bruce Wayne's return too, but it's all so crazy that at this point I'm just along for the ride. Again, I'll have to trust that Grant Morrison has a plan for all this madness.
I love Andy Clarke's work on Batman. This guy should permanently join the stable of Bat-artists working with Morrison. His style works perfectly for this title.
