Klaus use to enjoy his killing nature, way back when. The older vampire became boring the more invested in people he got. Though he was sure Klaus never did much like Jack with Rebekah.
Jack's black eyes looked over at their other victim making the boy shake with fear. Jack did not hide his hunger or lust for killing from those who would not last long enough to speak to others about it. Jack grabbed her hair to control her head and with a smirk aggressively kissed her. "I want to rip you apart," he growled.
Fingers curled around her thigh, under her skirt and between her legs. With the distraction of his fingers, Jack bit down hard on Rebekah's throat and tore a piece away to let her blood flow over her pale flesh. He had no fear ripping into her as he knew they healed quickly, but she would bleed long enough to let it saturate her. Her pretty little dress would be ruined so entirely by the end of the night.
