Gotham Underground #4 - DC

This has proven to be an interesting story-line. It seems like the purpose of it is to highlight all of the characters in the Batman-family . . . good, and bad. This issue we see a new crime-boss on the scene. I think his name is Scars. I could be wrong. He's kind of a patchwork man. His face is made up of 7 or 8 pieces that look like they were all haphazardly sewn together to create his own. He's also in to collecting body parts, as he hires a hooker for the sole purpose of removing her rather attractive ear. I know. Go figure! Apparently, somehow, he's hooked up with Mannheim and the Church of the Crime Bible. Anyways, Batman is still in prison, but he's faked his death because he wants to see what they're holding in the room behind the infirmary. He finds out it's the Great White Shark who is literally on his death-bed. Meanwhile Scarface and his gang have decided to make a run at the Iceberg Lounge. They want to find out what's been happening to all the other villains. But Penguin has his own group of metas waiting for them. They stop them and send them running where they find the Scarecrow who says he can lead them away. They end up in an alley where Tobias Whale has shooters waiting on the rook . . and they take them all out like fish in a barrel. We also find out that Dick is now posing as one of the gang members in Penguins little troupe. But, the Vigilante is on his trail. And Robin has gone to Barbara, with the Spoiler, to see if she can help figure out what's going on. But the Spoiler comes to, goes invisible, and takes out all of Barbara's equipment. Like I said, we're covering the whole spectrum of the Batman family here. There's even an appearance in here by the Commissioner and Harvey. I'm just wondering what the ultimate goal of this story-line is. We're about half-way through, there's 9 issues, but I don't see the connecting thread yet. Well, except that they're all in Gotham. Frank Tieri writes it and J Calafiore does the art. It really is a fantastic series. I'm just wondering where they're going with it.
