Now that we’ve got the Cybermen identified as the villains of the piece, it makes Tobias Vaughn an even more interesting character. He certainly seems to have all the angles, and fully plans some backups and contingencies to make certain that the Cybermen will honor their end of the bargain and make him master of earth after extracting the minerals that they claim they need. One of these contingencies is the device that Professor Watkins has built: it introduces emotions into Cybermen. The villains on Earth revive one just to test it out, and give the Cyberman a powerful dose of fear. It goes insane and climbs down into the sewers beneath London; that’s where the growing army is awaiting the signal to invade.
What Vaughn doesn’t know is that audiences of the day had the chance to see the Cybermen in action four times prior to this story. They’re real big about making deals that they have no intention of honoring. But then again, they’ve never dealt with anybody as ruthless as Vaughn before.
It ends with a great cliffhanger that sent our son behind the sofa again. I think this one might have been too talky for him to really understand that these strange circuits that the Doctor is finding inside unrelated pieces of IE tech are integral to the Cybermen’s plan. I’ll have to go over that again tomorrow night. But he certainly came alive when a policeman climbs down in the sewer after Jamie, Zoe, and Isobel, who’ve descended to get some photographic proof of the aliens. The policeman goes the wrong way and is immediately gunned down by Cybermen, and, down another corridor, our heroes have the maddened, yelling, fear-crazed Cyberman charging at them. “That was REAL SCARY!!” he bellowed.
