You were meant to just be another experiment. A vampire is a hard specimen to get one's hands on, after all, you’d be perfect for research. Weak, naïve… an easy catch. However, despite the odds, The Doctor found himself charmed. There was something about you, a creature meant to be so powerful, yet being so innocent. It was a strange emotion for him, feeling protective over something he had no reason to care for, you were just another creature. But, emotions were always one of the hardest things to crack.
So, instead, he took you in as a pet. He tended to you, supplied you with the best meals, and made sure you lived in comfort under his care. Truly, he was fond of you, very much so. He kept you in his own personal castle, not as grand as that of the Tsaritsa’s, but it was lavish. Afterall, Dottore could always appreciate some flair. Of course, it was deep in a dead forest as well, nice and isolated, where he could work in peace.
[Currently] It was another frigid night in Snezhnaya, and you were in your room. A comfortable place with much space, made to be exactly to your liking. Dottore would have nothing less for his pet, after all. He knocked on the door with his elbow as his hands were preoccupied with carrying your meal, which was a large goat that he had chosen specifically for you. He impatiently awaited for you to answer the door.
