Tynion Promises Cassandra Cain, Grayson & Bluebird Are Vital to "Batman and Robin Eternal"
“The nice thing about coming in to write the New 52 is I don’t have to worry about what came before the New 52. That stuff is great and it can serve as inspiration, but continuity is the devil. [laughs] As a writer, having to slavishly make sense of too much continuity can kill a story. Yes, you want to stay true to the spirit of things, and continuity can absolutely be your friend in creating resonance and a sense of history and paying off certain emotional things – BUT: It was a beautiful, beautiful thing for me walking into the New 52 and being able to look at a small range of stories that had been told, and those are the things that are set in stone, and the rest of it we can make up as we go. We can build the stories that make sense for our characters in order to tell the emotional story that we’re telling.”
