Klaus turned when Rebekah was only steps away from Vivianne, and she saw the flash of his fangs just before she felt them tear into her. He aimed for her throat, trying to reopen her wound. She shifted and spun so that his fangs sank harmlessly into her upper arm. She continued her rotation, landing a solid kick that would have liquified his internal organs if he had been human.

As it was he staggered back, taking a piece of her arm with him as he did. Vivianne shrieked like the damsel in distress she was pretending to be, and Rebekah could feel that her throat had healed enough for her to find her own voice again. “How do you...not see...what she’s doing?” she demanded, ducking below Klaus’s next attack and using his momentum to throw him to the ground. “Is that delicate...flower...the Viv you fell in love with? She’s manipulating you...idiot.”
