The vampire let the victim scream for a couple of seconds. She seemed to think that it was going to be helpful in some way. That was the problem with humans. They did things like scream and didn't realize that it was just fodder for a predator's natural instincts. It made the nerves tingle, the reptilian part of the brain slither, the hair rise in delicious anticipatory goosebumps.
"Look at you, Aidan." Bishop beamed. He'd been there the whole time, watching. "My boy."
"You always did like me better when I was a killer, Father."
Aidan ended the screaming quickly, his hand cutting of the breath while his teeth found a vein to open. He took a little more time with her, draining her, letting her fill him up. The problem with a good blood drunk was that being satiated and full didn't matter. Gorging and gluttony were the guests of the hour.
He heard the door open and cared very little at first, until the scent of the newcomer reached him despite his head being buried in the hair of his current snack. It was something he'd never smelled before. Ancient, but very alive. Powerful. It called to him, that aroma. Aidan stood up to peer around the door. The body hit the ground with a dull thud when he stopped giving a shit about it.
She was strange, her bright orange hair standing out in the strip club like a flower in a nuclear wasteland, glowing ever so slightly as a rotating blacklight found her once, then twice. Lithe, she was, thin but strong - he could tell. And ready to fight. Aidan watched her quietly from the shadows, obscured mostly by the door, but additionally hidden when the lights would swing in his direction and cast deeper darkness over his position.
