Dinah heard the movement of the hyena in her direction just a little bit too late. She fell backward under the weight of the animal, and tried not to cry out as teeth sank into her arm. It hurt like hell, and Dinah struggled to get the hyena to open its mouth and release her arm. She didn't feel right about punching an animal, so instead her free hand fumbled about until she retrieved the gun loaded with the tranquilizer.
She fired the gun in the general direction of the hyena, though she didn't really have much time or clarity of mind to aim because the pain was definitely a distraction.
