Continuing to be more reasonable than he has any reason to be, Tom Brevoort is thinking about how it works in the Marvel Universe:
There’s a school of thought that there are certain elements of a given character that are sacrosant. And there are—but the list is much, much shorter than many readers think it is, I think. And it’s a very subjective list as well—the things I think are sacrosant may not match up with the things Axel [Alonso] thinks are sacrosant, may not match up with the things a given reader thinks are sacrosant… Every writer brings a slightly different take to the table in terms of the characters—the same way that every fan has a slightly different take. It all depends on when you started reading the books, what your formative experiences with the characters were. And the plain fact of the matter is that, when you’re working within a shared world construct like the Marvel Universe, there really is no one firm, set, eternal answer. Every answer is true until it isn’t true anymore—until somebody manages to tell a story that, good or bad, changes the perconceptions people have.
Which is to say, he thinks you’re all wrong, and that Tony Stark is awesome.
