It came in waves, their shared pain, two people who were not the same because she wasn't exactly his Natasha and he wasn't her Steve. But they were, or they would be. It felt the same, not like the people from other universes who didn't quite fit. She fit. Two people who knew just where to come together, knew where the sharp edges were and where to settle. It wasn't healthy, they both knew that, that their family wasn't ideal, that being so wrapped up in one another especially when things weren't and never would be romantic wasn't normal. But they were far from normal. They needed something to hold onto and it was each other, it had been for a long time.
As she relaxed Steve let her arms down, her legs up, the two of them finding a way to stand together, to not collapse down onto the ground and give up.
He'd been in her shoes, he'd made that choice and given his life to save the many. To be angry at her, it wouldn't help. Not when she was here and warm and real. The full extent of losing her wasn't something he could really wrap his head around, not when it was her there telling him about it. Steve wrapped both arms around her waist, leaning his forehead against her shoulder as he finally breathed out slow and long.
"Checks out, cant imagine we watched everyone disappear and then went our separate ways," Steve said quietly. No they'd have kept going, one foot in front of the other, because that's what they'd always done.
Steve didn't want to ask, he didn't want to know. But he also couldn't help it. Best to rip it off like a bandaid. "What else?" He asked quietly. Because there was more, there was never an end to it, Steve realised that now.
