For some reason, Tony simply hadn't factored in the idea of Steve being there to be a part of his future family, showing up for visits and allowing himself to be shame ranked in single digits by a little girl that was clearly smart enough to keep Captain America on his toes.
It was sort of bittersweet, that knowledge. Just more in his head that he wasn't sure how to deal with or make peace with just yet. But he sort of liked it, the idea of Steve devastated by probably arbitrary numbers.
When the phone gave up the ghost, Tony let out a little noise that was embarrassingly full of loss, even though he was well aware that he could fix the thing without any issue at all. It was just a right now sort of thing, when he already felt like something had been ripped away from him before he'd ever had the chance to have it.
He rubbed a hand over his face, tried to get himself together because it wasn't fair on Natasha, it really wasn't. She'd given up more than him. "No. I -- thanks. I'm glad. You know." He'd save those pictures for himself when he got her phone working again. This wasn't the last time Tony would look, he knew that. "She's beautiful. Natasha."
