From Inside the Grey House:
Natalia’s anger flourished in his apparent detachment. Her anger consumed her and wrapped her in a blanket of raw heat. Logic was gone; instinct took over. She grabbed Anthony’s staff and swept Vincent off his feet before anyone knew what was going on. He fell to the ground and she pressed the end of the staff against his neck. Were he human, his air passage would be blocked. Natalia and Vincent locked eyes, neither looking to concede.
