"Good. Then that confirms that the signal to the brain can be disrupted. Which is very good to know." The Doctor nodded before he arched an eyebrow at Jake as he crouched to study him. The Time Lord's head tilted slightly to one side, eyes narrowing a tiny bit as wariness crept into them. Then sighed and ran a hand through his hair after a shake of his head. "I've been hearing them since they started. Not just the ones in my own head. Oh. Right. Are they different?"
The Doctor managed a small grin and patted K9 on the head. "Oh, that was easy, K9 here's been keeping a monitor on your.. range? Yeah, lets go with range. Good word that. Yes, that, he's been keeping check while taking readings of the 'fog'. Not to mention my own heightened senses and all that, I'm quite good at finding people when I need to. Now! What can you tell me about this place now your head's clearer?" The Doctor's eyes flicked about as he spoke, his attention seeming on more than just Jake at the same time.
