"Ed [Brubaker] got too busy, so Ed had to leave. Sales were what they were — it was Iron Fist. It was critically acclaimed, and not losing money was enough. But David Aja was going to stop because of the schedule and other work, and Ed was going to stop because of his schedule, and I basically didn’t want to be the Mike Love of Iron Fist, the only original member left ruining what you remember about the band. So I said alright, we’ll stop at #16. I knew what my twist was, what my end was, I thought I’d do that sort of West Wing thing where you end with a “holy fuck!” moment for the next guys, and let them have fun building everything up and finding out what the new status quo is. So it felt more important to go out on a high note with everybody happy, than to be the guy who ruined the book."
