The Doctor really wasn't expecting any company and it wasn't until the other man spoke that he even realised anyone other than the vampires was approaching him. He gave the newcomer a friendly wave, a little too optimistic for a man being hounded by three vampires. "Well, I did sort of ask for it," he admitted rather casually.
Apparently getting bored of his stupidity, one of the vampires made a move to lunge at the Doctor, who produced his sonic screwdriver in a rather triumphant manner. Sure, it wouldn't cause any long-term damage (or much short-term damage for that matter) but if they didn't know that it would at least buy him some time. "Not so fast. I'm not here to fight, I just want to know what you are," he explained calmly. He glanced up at the other man, about to explain the situation further when he realised what was odd about his appearance. "Aren't you bloody freezing?!" he asked, pulling his eyebrows together in confusion. His lack of concern over the approaching vampires was alarming to say the least.
