Caroline picked up on the other vampire's heart beat immediately. Jill was Moroi; she fed like Caroline, but that was where the commonalities came to a screeching halt. Jill was alive where as Caroline was technically dead. She figured she'd be close to the equivalent of the Strigoi in Jill's world aside from the fact she like to think she had better fashion sense and more control over her blood lust.
When the young woman appeared, Caroline stepped into her path, arms folded across her chest. Didn't the little girl always have one of those Dhampir things around her for protection? Caroline couldn't pick up on another heart beat though; it was just Jill and her. She could kill Jill and only have to deal with, at best, a very pissed off Angeline. She was hardly a threat to Caroline though. Caroline could toss her away like trash.
"Where is your guard dog?" Caroline asked in way of a greeting.
