With everything that Wonder Woman can offer to Superman on the list provided here, I'm curious to see what's going to be used.
So far, in Justice League #15, it looks to me like not much as WW seems more like a sidekick. He's telling her what to do. She's just nodding and following his lead.
[Mind you, she's got the same problem in her own book where others tells her what to do because she's always clueless of what's going on.]
Even her [demi] goddess status was told to him off panel like it isn't as important as him showing on panel his Smallville backstory.
And call me paranoid but when there's a big page of them running together to handle a threat, guess who's bigger than the other one instead of choosing a better angle to promote them as equal?
