That kind of why I think Arthur didn't want to be the king. He knew he'd be losing all of his hard work with calming the surface world, now though what has happened has gulfed the relationship between Atlantis and the surface considerably. He did say though perhaps he could still make something come of this. Hopefully that happens, but it seems like it's gonna take a long while...and probably not until after the Trinity War before diplomatic relations start to heal...if they even do.
Wonder Woman #17: This is still my favourite New 52 comic (slight nudges above "Batman"). Just great story telling and character development combined with fantastic art. I'd say that Chiang's art has improved since his first issues on the book. Orion's slap on Diana's ass and her reaction was funny. I think it's the character interactions though that I love the best about this book.
