Well, that was unusual. The Doctor's eyes grew wide as he stared at the man who had made such a dramatic entrance with a sort of disbelief. This was exactly the sort of creature he'd imagined when rumours of vampires had started flying, not the strange little deformed dustbags that had been stalking him until now.
"Oh. Right. Hello!" he said, giving the man a sort of awkward wave as he tried to subtly look back the way he'd came. Great, he'd blindly wandered into danger like a complete fool. "Eh... do I know you?" he asked, considering the familiar use of his name. Telepathy was possible, but there was something about the man's stare that made him think it was more than a chance encounter.
