Steve rests his hand over Bucky's. Yeah, he definitely feels better. Steve can't be Captain America without being himself. That's why he was chosen for Project Rebirth. Of course it was the only person who really knew him who reminded him of that.

"Yeah, well, you're good at reminding me of that," Steve says as he laces his fingers through Bucky's because he can. "You're the one that knows it best."

No one else knew who Steve was before Captain America.
