"Well, it's a theory. I'm not positive, but it tracks pretty well with what I've found so far. I mean, how else, and why, could they pinpoint individuals the way they clearly are? A need for specific genetics is really the only reasonable explanation. If it was personal, they wouldn't be taking people from different times and realities, everyone would be from the same world and period."

That was just logic really. It was possible the city worked on a completely different platform, but logically McCoy's theory worked. He winced when the kid mentioned other ways to get genetic samples though. McCoy didn't like talking about sex with people his own age, with someone younger than him it was just torture. So he ignored it for the moment. It wasn't a direct question!

"Dr. Banner? That someone from home, or here? Because if he's here I'd really like to talk to him. And yeah, that's about what I figured, for the most part. The problem is that Jim's from the past, I'm from the future. The stuff I'd be telling him hasn't happened yet, so he wouldn't be going back in time to make changes, he'd be going forward. If stuff happens the same, anything I say that he retains after leaving here would let him change what's now my past. I mean, I wouldn't mind all those terrible things not happenin, but god. How can I tell him all that awful stuff? It'll make him hurt so much . . ." McCoy put on a good show of being gruff and rude, but deep down he cared deeply about his friends and crew.
