I'm looking for a shortish story I read at least a year ago on AO3. It's probably Steve/Tony friendship though it could be pre-slash I guess. In the story Steve finds out that Howard wasn't a very good father to Tony or even a good man in his later years. He is angry and storms out (to the roof of Stark tower I think). He talks out loud to himself how only one man deserved to have his name on the tower as his legacy and that the other doesn't deserve it (or something like that). Tony is watching a video of it and thinks Steve it talking about him not deserving Howard's legacy, but just as he is about to cut off the video feed Steve says something that makes him realise that he is talking about Howard not being worthy of Tony's achievments. Does this ring any bells?
