At that, Steve couldn't help but feel utterly, utterly grateful to Sam. After that misunderstanding about Bucky... Sam hadn't had to believe him, even though Steve had absolutely been telling the truth. He and Bucky were friends, that's all they'd ever been. And Sam didn't have to help like this to support Steve - but he was, and, "That... would mean a lot to me," he said, closing the distance to squeeze Sam's arm (gently, of course), then letting his hand slide down so he could squeeze Sam's hand, too. "But I don't want you putting yourself in too much danger, either."

He glanced between Sam and Dr. Goss again. "I... I'm willing to let you guys do this, if you think it's best. But if it goes south... we find some other solution." Even if it was one Steve didn't like.
