It was easier to think of Tony's family as just something that wasn't there, never would be there. But they existed, somewhere in time and Steve wasn't ever going to deprive the man he loved of that if it came up. He'd hope that maybe there would be a place for him there, that maybe Step Dad could be something he might earn. But it was almost too good, too special to think about. Like looking right into the sun. If he dreamed about it, it might destroy him if he didn't get it.
Steve's heart clenched, but this time in a good way and he nodded as he stroked his temple. "It looks good on you here, too," he agreed. Because seeing Tony with Gwen, Steve could see what a great dad he was and those two had a bond that was incredible to watch grow.
"People were grieving, they needed something to help," Steve shrugged. "I guess I was grieving too, but not just for what Thanos took, but for everything." Steve had felt like he needed to bring everyone back, that it was his job and he'd never had been able to settle or be happy. "I tried to make a life for myself, but nothing stuck," he admitted after a pause.
