It would have been maybe too confronting to know that they were a them. Confronting but also confusing because Tony was gorgeous but too old and the attraction just wouldn't have been there for either of them. No it would have been its own kind of hell and Steve was incredibly glad they were back where they belonged.
Being back in his bed with his boyfriend, the warmth of his skin, it just reaffirmed that Steve was just where he belonged. Nothing and no one made him feel as peaceful as Tony did.
Never one to miss the chance to lighten the mood Tony asked about Natasha and Steve laughed. "We're postponing the wedding for now," Steve agreed somberly. "I mean we didn't even have a white dress, who were we kidding?"
