Newt Scamander was researching a case with Tina about some missing muggles in the area they believed the cause to be a vampire but to be sure they had to set a trap and Newt ended up being the bait.
That's how Newt ended up running through dark alleyways being chased by a vampire who apparently loved to play a game of cat and mouse.
He was making his way through one when there was a rush of wind and he was knocked to the floor.
Newt looked around on high alert knowing the vampire was near he drew his wand at the ready brushing himself off before standing he found himself speaking rather softly. "Come out I know you're hear wherever you are."
This proved to be a mistake when he felt a tap on his shoulder dread filling his stomach he had no time to move before his wand was knocked out of his hand having no options left he made a run for it which proved to be futile as the female vampire sped in front of him with supernatural speed before grabbing him and biting into his tender flesh on the side of his neck. She then silkily whispered in his ear. "Don't run from vampires. "We like the chase." Before biting into him again but it wasn't gentle like before this bite was nearly animalistic fast extraordinarily painful and to the point. Newt felt his consciousness leaving him before he was out of it completely though he felt something fall past his lips something metallic as the vampress hummed a eerie melody he heard her whisper" No more rules….."
And his world was taken away from him.
Just a one shot idea.
