I'm guessing he's under the impression that Gordon is in Falcone's pocket now since Falcone let him live. I'm also guessing it's the only reason Gordon still has a job. The mayor is assuming if Falcone wants Gordon alive then he also wants him to remain a cop, but the mayor can still do what he can to make Jim's job miserable.
I didn't even know that was supposed to be Copperhead? In any case, she was cute/sexy and a decent fighter. I wouldn't mind her showing up again. Although, it's weird that she's another of Batman's rogues that's about 20 years older than Bruce.
Speaking of Bruce, am I imagining things or was he sporting a very faint mustache? If so, then how old is Bruce supposed to be? I was under the impression that he was about 12 but most boys don't develop any sort of facial hair until about 15.
