Steve laughed, kind of a rumble and he smiled through the stray tears on his face. Because Tony was, as always, so completely Tony no matter what the situation. It killed him to think of a world without him, what a sad place it was and the mourning hit him all at once. Morgan without her father, just that thought alone was enough to nearly make him sick. That little girl so much like her dad, a piece of happiness he'd never dreamed of for himself, it had been so special just to witness it. Wasn't that what Steve did best? Watched other people's happiness from the sidelines?
"The whole fucking universe," Steve agreed as he tried to swallow down the burning in his throat. There was so much, looking at Tony now he could remember the spitting fury of when they'd got him back. There was going back to his own time, fighting himself, just too much information all at once and he closed his eyes because it made him dizzy.
"It had to be you, I know that, okay? I know," Steve said as he turned his hand, so their palms pressed together and he could entwine their fingers. "But I don't want to keep going without you, I shouldn't have to live in a world without you in it," he said. "I've been through enough, I-" his voice broke and he brought Tony's hand up to brush a kiss against his knuckles.
"I love you, I loved you then and I love you now, in every time and place," Steve said softly.
