The Doctor heard the nearly tiny, broken voice as it came from the shadows. There he went, counting them, taking stock and making absolutely certain that every one of them had an owner and a source. He was starting to think that episode had made him phobic of libraries the way that Midnight made him phobic of tour buses.
The Doctor could hear what direction the voice came from, and even the slow steps; but as of yet, the figure had not revealed herself. "It's me, hello," he said quietly, waggling his fingertips before shoving his hands into his pockets and shifting back and forth a little.
"Who's the owner of that voice back there?" His smile never faltered as he tried to peer into the shadow. "Only fair you at least tell me your name," he prodded playfully, choosing not to move from his spot lest he frighten away whomever was tucked back there.
