Love him or hate him, Morrison has us all atwitter with the RIP storyline. I have re-read most of these issues and tried to figure this out, and it's either hiding in plain sight or buried deep.
I sincerely hope that Bruce Wayne is not being written out of the mythos. That would be the ultimate hubris.

So, what do you think?

I think the Black Glove has to be Thomas Wayne.
Or, maybe, some relation to Jezebel Jet.
I thought she might turn out to be Bruce's half sister, but haven't they gotten busy? That would give me the shivers.
