Bendis is interviewed!
http://comicbook.com/2016/12/28/civil-war-ii-ending-brian-michael-bendis/CB.COM: Civil War II was extended from a seven issues to eight. How did that effect the ending?
Bendis: The actual events didn't change, but how the story was told changed. We'd been thinking about the visual dynamic of Ulysses’ powers. In the earliest, earliest, earliest version, before you even heard there was an event, we started to think about what kind of ending Ulysses brings us. Do we kill him? Does he join the Avengers? Does he join the Inhumans? Does he go bad? Does he snap?
He keeps being hammered by tragedy. He feels them and some of them are really going to happen and some of them are just going to happen to him. Regardless, if you're young and you're idealistic and suddenly your brain just gets hit with everything horrible that could possibly happen, it will change you. Does it change him into a villain?
There were all these opportunities, but the one that was the most intriguing to me and to everyone else when I pitched it, is that he evolves past profiling. The profiling is a stepping stone to another step in evolution beyond anything the Inhumans have ever experienced and what it does is it removes him from future storytelling without it being like a Twilight Zone tragedy, like, "Oh my God, he died in the middle of one of his own predictions."
So this evolution, this evolving of him, to another part of Marvel, that maybe will bring stories down the line is very interesting, but how to capture that evolution, visually in the comic book to really sell it, was something that I thought could use some more pages and when you turn the page and see Eternity and the other Elders of the Cosmos, that's not an eighth of a page. That’s, you turn the page and that's a double page whammer.
