Human race. For such an intelligent lot, you aren't half susceptible. Give anyone a chance to take control, and you submit. Sometimes I think you like it. Easy life.
Ah, there are Cybermen in our universe. They started on an ordinary world just like this, then swarmed across the galaxy. This lot are a parallel version, and they're starting from scratch right here on Earth.
Oh, Lumic, you're a clever man. I'd call you a genius, except I'm in the room. But everything you've invented, you did to fight your sickness. And that's brilliant. That is so human. But once you get rid of sickness and mortality, then what's there to strive for, eh? The Cybermen won't advance, you'll just stop! You'll stay like this forever. A metal Earth with metal men and metal thoughts, lacking the one thing that makes this planet so alive: people! Ordinary, stupid, brilliant people!
