He opens his mouth to admonish Steve, but then it snaps shut again as he remembers what it felt like -- on that rooftop with Pepper. How long it had taken him to reach out to her again because he'd been so petrified of losing her. "It's just a question," he points out gently instead, though if he thought Sam were the kind of man to hurt Steve, well. He'd be answering to a gold-titanium fist. "And if he didn't want your drama he wouldn't be dating you, doofus."

There. He feels good about that, reaching out to tap Steve's shoulder in a mirror to the one he'd gotten. Tony would let Pepper handle this from here on out. His press conferences were pretty much like Steve's would be so that's a no-go.

"But if he ever hurts you..." His face creases in worry. Not because he thinks Sam ever would, but just because he's become so fiercely protective -- even possessive -- of what he has that he can't let it go. Tony doesn't finish the sentence, looking away. The meaning is clear enough without the rest of the words.
