Claire was concerned about him. She did not know if he would actually be able to get back up and do everything that he wanted to do, but she wasn't going to be telling him what to do. He insisted he was fine and Claire had promised not to tell. So she would just let him get back to business but that didn't mean that she wouldn't be checking on him at some point down the road to make sure he was okay.
She gave a small nod and wave, and turned to leave the alley.
