Tempus saw the way she seemed to smile. That little smirk she seemed to get when she knew something. The Doctor simply exhaled sharply to show his annoyance. "You're right, I wouldn't have let you in" he replied somewhat bitterly. "I let nice people in here" he added. It was rather childish of him but he was like that from time to time. Perhaps more than he'd care to admit.
"And that is none of your business. No injecting, no planning" he rambled. Of course, he was lying. He hadn't told anyone about the Reathanol. Well, no one except for Seeker. She knew. She would be the only one who ever knew if he could help it. And besides, if River found out... well he didn't want to think about what could happen. As each thought passed his mind, he seemed to react a little. His expression grew darker, his gaze, more distant, directed to the floor.
Coming out of his self induced daze, he looked to her again. "I hope you've been behaving yourself... None of your... nasty glyphs left hidden away, hmmm?" he asked her.
