"By all means," Demi purred, watching the couple he'd pointed out. "Push away." They had a devastating one-two punch when they worked together; Lazarus able to nudge their targets into an unnatural frenzy, leaving them with dangerously lowered inhibitions and a hunger for more. What the 'more' was didn't matter, not to Demi; whatever they wanted, she had the power to grant, and she never shied away from giving it to them. It could almost be considered philanthropy, if philanthropy hadn't been antithetical to her nature.

The trouble, of course, was keeping them sane long enough to be useful to her and hold up their end of the bargain; the crazy ones either died before she could claim her favor or weren't able to be coherent long enough to manage the job, and they ended up dying as a result of breaking the bargain. Not that she minded a messy, immediate death, but if she wanted gratuitous murder she could just go on a killing spree. With these thoughts in mind, she lightly trailed one black fingernail down the back of his hand.
