Bucky spent most of the next day in Stark's lab with Tony and Bruce, feeling like a glorified guinea pig.

He had MRIs, CT scans, X-rays, blood tests, urine tests, a 2D Echo, auscultations, palpations, brain scans, some tests he'd never even heard of. His arm alone had garnered a good hour's attention. Once they did move on to other things, Tony kept casting sideways glances at it, making it clear he badly wanted a lot more time with it.

Bucky appreciated the fact that neither man made a comment on the extensive scarring that decorated his torso and shoulder.
