(I've heard some people say that Morrison's run is intended to put an end to the paranoid and cranky "Batdick". Apparently the way to do this is to write Batman being more isolated from the people he cares about)
Bingo.
Fun fact for those who care: Elva Barr was the name she was using during a screwball plot where they got engaged in the Golden Age, YEY MORE POINTLESS MORRISON TRIVIA... And actually, I was spending the whole run going: Okay, is he trying to play Derrida and have the lack of Catwoman in any form or mention be "Vast presence equals vast absence blah blah" Or... What? I still don't know, and the lack of Bat/Cat is glaring. But that would still be my GUESS as to why she's had so little mention. I just don't think, along with so many other things, he pulled it off well at all.
As for Last Rites... Charitably speaking (I don't know WHY I'm being charitable, I guess my heart grows a few sizes on Cinco De Mayo eve) Catwoman took a very long NAP during the Silver Age, returning when the TV series made her big again, and Batwoman showed up and left before she arrived, if Morrison IS saying the Silver Age Happened... Well, it would likely be a time that Catwoman wasn't around much for whatever reason.
The fact that he sees her in the nightmare vision as merely an "ordinary" grifter and Daddy Does Not Approve? That actually DID say Bruce nightmare to me, and maybe imply that Morrison DOES see him giving a crap about people who are historically beloved of him and not named Dick or Alfred. But at this point I don't even know if I'm not just reading it in as best a light as I can because a part of me thinks there has to be talent and insight lurking SOMEWHERE in a comic with the name Grant Morrison on it.
And because of that awesome vision/dream/fear wish of his marriage to Selina in The Key storyline from JLA... That too.
