"They've slowed down" The Doctor spoke whilst scanning his sonic screwdriver over each of them, making sure to thoroughly examine his findings. "Their brains are functioning, but only at a very small percentage. It's just enough to keep them alive but not enough to get them on their feet."<br/><br/>"We have Mickey Smith, Heather McCrimmon, Wolfgang and many others just like them in our other cells," Gwen explained whilst leaning on the cell door, her gaze fixed on her husband and child. "They've been like this since Boxing Day, along with every other human on Earth"<br/><br/>"So this is what the Silence meant. The human race no longer controls Earth because they can't defend it," The Doctor said before walking over to Martha's side and frowning deeply. "What caused this? Is it the psychic beacon?"<br/><br/>"No. Using Sky's computer skills we managed to get a thorough look at the coordinates of the beacon and its purpose. It turns out that its coming from several orbiting satellites and all they're doing is showing aliens how to get to Earth and explain the rules of the competition"<br/><br/>"That's odd," the Doctor said. "This is almost full cranial shut down, if they didn't use the beacon what did they use and why didn't it affect you?"<br/><br/>The Doctor paused for a moment and scratched his chin with the end of his screwdriver as he mulled over the problem. Eventually he clicked his fingers and pointed to Robin, "Miss Baker your talents are needed. I need you to scan Martha's brain."
