The strength of Steve's hug lets him know just how worried his friend was, deep down. Bucky puts his arm around Steve's body and holds on tight in turn until Steve pulls back and steps away.

He realizes why immediately as Sharon comes up to him. He draws her in, holding her close, and breathes in the scent of her hair as she murmurs a soft welcome. "I'm back. I'm here. It's okay," he says, just as quiet, and as reassuring as he can make it.

He hasn't taken all the tests yet... especially the most important one, the one he's not sure if Shuri even knows about. Maybe he shouldn't make any promises. But for now, in this moment, nothing else matters.
