Sabrina knew Dan surely did something, that pitch-black eyes were a signatory for vampires who were overwhelmed by their powers and possibly given in to their dark side.
She gasped when a dark smile curled up his face, revealing sharpened teeth among the first neat row of white teeth while his eyes were so black that she couldn't differentiate the sclera from the pupil and she understood she was endangering herself by being so close to Dan at the moment.
With heavy breaths, she stepped back a bit but there was no way to run to while Dan kept staring at her interestedly, the way he was watching her sent tremors all over her body.
Sabrina knew this was a game to him, cause he stood there, though unmoving but poised to act, as if he was the predator and she was the prey, watching and inspecting the best time to move in for the kill.
