@ccraft: I think the jumpsuit and toolbelt were because he was "fixing" Batman by removing the Bat-Family, and the Joe is just a reference to his name, Joker, and it's a name you'd expect to see on a coverall worn by a mechanic (also it's a lame Joker joke).
Joker was going after Nightwing. He was able to piece that there was SOME kind of connection between Nightwing and the circus, since in previous arcs Nightwing was showing up in cities around America at the same time the Circus was there. He didn't necessarily know what the connection was per se, but he knew that there WAS one and that hurting the circus would probably hurt Nightwing.
I think the attack was more towards Jim Gordon. He had previously shot Jim's daughter and now was terrorizing his ex-wife as well. I don't remember any particular mention towards Batgirl and Barbara or Joker making any connections between the two, but perhaps he noticed Batgirl's absence for awhile while she was paralyzed, so he might SUSPECT a connection but not have any solid evidence to go on (not quite as sure about my theory on this one, might have to re-read Batgirl).
Maybe I'm just a big mark for DC, but I kinda loved this book. The part with the cat made me misty eyed, and the whole Superman having sex thing brought great Mallrats flashbacks. Parasite's design was creepy and very sci-fi, and the dictator thing worked for me and for the tone of the book. Maybe I'm just too easy to please, or maybe I'm not nitpicky enough. I can't figure it out.
OK I am totally missing something that is apparent to everyone else. Can someone please explain the following to me?
1. Why did he add RED to Red Robin? I understand he wanted to make it connected to the Robin legacy but make it something more, is IS there any significance to the Red part?
2. What is G-man talking about on the last page? I reread it and I can't find the name thing he's talking about. I THOUGHT it was the RED part of the character's name, but is he implying that Tim Drake isn't his real name? Sometimes I need things right in front of my nose to see them.
