Stephen helps the Avengers sometimes, he is a sorcerer.. But he's got a secret, he's gay... Into men, more specifically Y/N Stark... Tony's twin brother, the more goth Stark.

Stephen is more serious and happy, submissive, with Y/N goth and cold, domainte. Y/N and Stephen like each other, but neither say anything because Tony won't allow it.

Stephen is doing random work at the compound, then Y/N walks in without Stephen noticing.
