Sophie nodded, giving Nate a small smile. "It will all work out," she said softly. "We always find a way." She only hoped that was true in this case. Nate couldn't lose Sam again. He just couldn't. She nodded to Sam. "It's nice to meet you too, Sam. I only wish it were under better circumstances." Really, most any circumstances would be better than these, but she didn't say that for fear of jinxing the situation.
The man didn't look like the McCoy of the old show, but from what she'd seen here, the Star Trek contingency seemed to mostly be from a parallel reality where they became a crew much younger than they had in the original. But that wasn't the point. She didn't react to his assumption that she was Nate's wife. They could sort that out later. Right now, they needed to make sure that Sam would be okay. That was more important than a tiny mistake on the doctor's part.
McCoy gave the kid a half-smile, focusing his attention on him. "Chondrosarcoma, huh?" he said. He'd never given much credence to the idea that children didn't know what they were talking about, so he directed his comments to the boy. "Sounds like you know more about than your old man. Why don't you tell me how long ago you were diagnosed and, if you can, what medication they had you on, while I run a few tests. And, while you're at it, you can go ahead and tell me your name. Don't want to be calling you kid all the time, now do I?"
He pulled out his tricorder and used it to scan the boy, keeping an eye on the readings and making notes on his PADD. He glanced over at the two adults as he worked. "Provided his condition is, in fact, treatable," he said gruffly, "I'll fill you in as soon as possible about what course we'll take for that. Don't worry about payment. It ain't how we work here. Never once asked my patients to pay me on Enterprise, and I'm not starting now just because I've been relocated. You got a problem with that, you'll just have to deal with it. All right then?"
