"Very good, Buffy." He smiled, but then round house kick, but she ducked in time to the kick. He was holding back, he had not meant to, but he was still worried about hurting her.
"Be prepared." Was his only warning before he lashed out with his vampire speed. He could control the eyes and the fangs, but he could let go the power. If she was quick enough she would be able to duck or block it, if not it would give her a nasty bruise later, not to mention is could break something.
