"Robert." Steve put a hand on Robert's shoulder to keep him steady him just in case he went stumbling backwards. Most people bounced off. "How's your sister feeling today?"
Rosalind had practically moved in with Clint and the rest of them at this point which was no business of Steve's. He imagined the two had talked about Clint's family and wife before now. What the two of them did was their own business. The rules just didn't apply in this crazy land.
Robert, though, hadn't moved in but he was here often enough to practically live there. The twin was pretty much like his sister, serious and scientific. He had yet to let either sibling take the shield. After his death, Steve was even more reluctant to let it go.
