When alerted to the presence of an uninfected human or flashlight, she will look in the Survivor's direction and make a low warning growl: this signals an incipient attack. If the Survivor backs away a fair distance or is no longer in sight, she will gradually return to her wailing state, taking longer if the intensity of her warning growls is high. However, if the Survivor is still nearby, she will slowly stand and flail her arms in a threatening manner; if the Survivor does still not move, she will single them out and run at incredible speeds. She is able to incapacitate her victim instantly whereupon she frenziedly slashes that person with her clawed hands, only stopping if either she or the victim dies.
