Closing his eyes, he continued petting dark hair, smiling at how it curled around his fingers. He always preferred when Tony looked less like the media image and more like the guy that danced around the workshop to rock songs that Steve had finally begun to recognize. It was easier to talk to that version of Tony than the version of the genius that dealt with public.

Or he usually did... the riddles were a little weird but still someone he could talk to without feeling out of place.

Chuckling when Tony decided to pin him, he pretended to let out an annoyed 'humph' when his friend's weight settled on him. His hand stilled for a moment when the Tony spoke before he kept playing with the curls at the back of Tony's neck. If his hearing hadn't been improved by the serum, he might not have caught it but the words caused an flutter in his chest.

Somehow Tony kept reminded him of who he was supposed to be. Not the soldier or the hero but Steve Rogers. And that person was perfect to Tony. Just like Tony had become perfect to him, strengths and flaws important to the whole. Maybe he'd found home and hadn't realized it and that was why everything relating to Ultron had hit so hard.

Curling an arm around Tony, his breathing slowed and he had the feeling that the nightmares wouldn't show up this time. "G'night, Tony."
