"Yes!" the Doctor responded to the comment about his speaking too much a little too eagerly. "I've been told that!" he grinned, patting his pockets as he tried to figure out what he'd done with the key.
"Oh, I think we'll fit in there just fine," he commented with a little grin; how many people had he had this exact conversation with now? He came across his key at last, and tucked his sonic screwdriver back into his pocket as he glanced back to check the vampires were still dazed and confused from the sonic disruption. "And trust me, they definitely won't be able to break this door down, even when they do get their senses back," he nodded, popping the key into the lock. "Come on, this is definitely the safest option," he nodded before stepping inside, leaving the door ajar for the man to follow him, which the Doctor knew from experience he eventually would.
