Blue As True As Blue Can Be (слэш)

Tony Stark has worked hard to make sure everyone sees exactly what he wants them to. After all, they'd all rather see the asshole with the too-bright smile than the terrified person underneath who is desperately trying to conceal that which has caused him so much pain. Trust him, he knows.
(Tony Stark is a mutant, and his father had made sure to note /exactly/ how he felt about that. Now, with the Avengers living with him full-time, it's getting more and more difficult to hide the part of him that almost no one still alive knows about.)
