Verity and Yaxley
Following the sight line of Yaxley's wand, Verity's mind froze. She couldn't think, couldn't move, suddenly stricken with a maternal fear that hadn't manifested itself before. Her instincts took over and she cast a weak and hasty shield, spinning away from him as she did so.
The hex broke through the shield and hit Verity in the back. She let out a short scream, the force of the spell propelling her forward and down to the floor where everything went slightly fuzzy with pain for a moment.
