Stephen is a sorcerer, sometimes helps the Avengers. But he's got a secret, he's married... To a man, yes GAY... He's married to Y/N Stark, Tony's goth twin brother.

Stephen and Y/N love each other, but married in secret mostly since Tony hates Stephen. Stephen is serious, goofy and submissive. Y/N is cold, never happy unless with Stephen and domainte.

Tony notices Stephen's last name change to 'Stark'. Then Stephen and Y/N walk into the room, so Tony asks.
