Dr. Stark

Y'know the unhealthy way Charles sees Raven as his ward? Yeah that's how Gregory sees Tony. He's always seen himself as more of Tony's dad than Howard was, it's hard for him to register that they're siblings, that he doesn't need constant protection from an abusive father, he doesn't need to take the brunt of a sad old drunk's anger anymore, not for Tony, and not for Maria. That was his whole life until he finished medical school. Protect protect protect. He just didn't realize that Tony needed his brother, not another father. It's why they didn't speak before Howard and Maria died, it's why they argued at the funeral, it's why they barely speak, because Gregory doesn't know how much he'd be smothering his brother, he doesn't know how damaging that is, he struggles to remember that he's twenty minutes older than his twin, not twenty years. tl;dr - Gregory needs to stop trying to be Tony's dad

Tony is Sherlock Holmes and Gregory is Mycroft, fucking come at me bitches, I'll fight anyone
