I wish you would write a fic where, The Doctor is a Vampire without a TARDIS and is meeting Rose for the first time. (Cause if I sit here and think about it there is a criminal lack of Supernatural AUs in a universe where both Werewolves and Vampires sort of exist)
900 Years. He had spent 900 Years on this godforsaken rock, visited every nook and cranny accessible to man, read damn near every book under the unforgiving sun. He had been named Lord and Tsar and King and Chief. He had built and burned down civilizations in the blink of an eye. But for all his bluster and grandeur, he had spent the last 100 of those Years eating nothing but alley cats and basement rats, skulking in the shadows and watching History play out at a distance.
There was very little he hadn't experienced, not much else for him to learn, or read, or do. Other than see how long he could survive on nothing but vermin, to see how long it took for his body to finally give out and put an end to the endless, ceaseless wandering. It had been going well so far, but he was hungry. Undeniably, gut-wrenchingly hungry. And seeing as he had eaten the last rat in the Henrik's basement the night before, it was time to move on.
Fortunately for him, though rather unfortunately for the integrity of his experiment, a lovely, ripe human had just stepped off the elevator. With a single deep breath, he learned all he needed to know - young, female, AB+, and already well-seasoned with the adrenaline coursing through her veins as she wandered the dimly lit basement alone.
His mouth watered as he stalked her, keeping to the shadows and timing his footsteps with hers. It felt good to go on the hunt again, natural even. This human female, so sweet and inviting, had unknowingly sparked something feral and primal inside of him, something hungry, ravenous. And each carefully placed step brought him closer... And closer... And closer. Until he was nearly pressed against her back, lips hovering just a hair's breadth from her ear. With a sinful, dangerous smile, he moved their game to the next phase.
