Tony had respected Bucky's wish to leave, for a little bit. He couldn't just stand back and watch his son suffer. It wasn't who he was. He needed to fix things, sometimes even stuff that couldn't be fixed. After giving the kid a few hours to himself, he came into the room with a tray of sandwiches and some sodas. Tony's eyes went a little wide when he saw the blood, but he tried to hide the shock.
"Looks like I need to go get the med kit." He tried to keep his tone calm.
