I dunno man
Tony Stark is saddled with a bad artist, and a writer who doesn't get him. In addition, his name is mud in the Marvel U, he has no power, is alienated from his friends, has seen the SHRA turned into ashes in his mouth... and has set himself to go full retard. By the time they catch up with him, he'll be a drooling, incontinent mess. What will they do with a guy like that, then?
He has been punished, and pushed to the margins, all that he worked for has turned to dust.
