This already happened!
Scott from Polite Dissent says you should never shock a flatline!
While Batman is making his way back to his Batlair to be healed by Alfred's super awesome tea, The Court of Owls is busy resurrecting Talons. If they resurrect more than one at at time, how is Batman supposed to defeat them all? Is this why the Night of the Owls is about to happen? Lots and lots of Talons who must be beat back by all of the Bat-Heroes?
Alfred's work is never, never, never, never ever done.
While Batman examines the corpse, Nightwing enters the Batcave and we see the scene from the end of Nightwing #7. But this one has a lot more added dialogue so I'm not going to demand my 15 cents back for each repeated page! Batman explains how the corpses were reanimated.
Here's a little story about Electrum.
I just figured anyone not reading this comic would like to see Nightwing being smacked around by Batman's pimp hand.
What building are they coming out of? It's covered in Owls! Don't you think Batman would have checked it out?
