Dracula was quite pleased with the way things were going so far, and even though he knew that he had precious little time in which to be free, all was not yet lost. He had Mina, after all, and despite her reluctance she was incapable of refusing him. She was one of the undead now, which meant she belonged to him. Now he needed to find Lucy, and once he accomplished that it was high time that he allowed them to feed. They needed their strength, and their first kill was necessary if they were to truly become worthy opponents to Van Helsing and his vampire hunters.
Considering the fact that Lucy was very likely a vampire as well, he knew it would be hardly difficult to find her - he sensed that she was somewhere near the eleventh floor, so that was where he headed, Mina in tow. "First we find your friend Lucy, and then it will be time for the two of you to taste your first blood." It was a statement, almost an order, one he knew neither of them would be able to refuse.
