You make it sound like this was something we were unaware of or unprepared for. Listen, we killed and replaced Captain America, and right now Otto Octavius is Spider-Man. Clearly we don’t have a problem with doing this sort of thing. I understand and even commend your loyalty to a character that you love. (Though, and speaking as a guy who bought Nova’s earliest appearances fresh off the racks, the notion that he was a “mainstay” for thirty years is a bit ridiculous. I love him too, but he wasn’t appearing regularly for at least half of those thirty years.)
