Peter's hand had been low, ready to fill with fire and unleash it at the vampire. But he had waited. If he stepped in too soon, the girl would probably hesitate. This was her vengeance, not his.
Though he didn't mind throwing in his hand, if necessary.
She took care of the vampire with quick efficiency. Peter had to give a nod of respect to that. When the chips were down, she did what she had to. Even though he'd heard the pounding of her heart from shock and horror, she had pushed past it. If she could maintain that, they'd be fine.
He followed her, further into the house. The scent of blood was one he never learned to appreciate.
