"Galen?" the Doctor repeated, a bit astonished that he'd gotten an answer in the first place. "That's a bit human, isn't it? Still, I suppose it doesn't matter. Before you hang up, this isn't a wrong number. Not if you happen to be sitting in a spaceship that has absolutely no business being parked in New York in the 1960s. Don't worry. I'm not going to report you, but I need you to listen carefully. Do you have medical supplies on your ship, Galen? Specifically, medical supplies that can be used to treat end-stage radiation sickness. If you don't know, put me through to someone who does, and do it yesterday."
