Stephen sometimes helps the Avengers, he is a sorcerer and a good one at that... But he's got a secret... Stephen is gay, into men... More like Y/N Stark, Tony's twin brother. But he thinks Y/N don't like him back, so he stays silent.

Y/N is Tony's twin brother, he's a genius like Tony and even helps Tony with things. Y/N loves Stephen, but never says anything since Tony hates Stephen. Y/N is a trained assassin and is best friends with Loki, since Y/N actually listens.
