She was a home-bound college student driving through rural Florida with her brother for break. Unfortunately, she and Darry encountered The Creeper along the way. However, she played a facade all along; under the surface, Jenner is a prolific serial killer, and far from the normal girl she pretended to be. That explains why she left her brother to sadistically die at the hands of Creeper while at the same time Creeper spared her because he perceived she was a evil person, and Creeper being a evil creature, liked the true nature of Jenner as a evil human as well. Ever since her first encounter with Creeper happened, she has a sort of father and daughter relationship with him whenever he comes to Earth, completes his cycle, then leaves. Jenner surrendered to her inner demons but she still claims she only commits serial killings on people who ask for it and possibly on self-defense as well. Her true number of victims is unknown ranging from 18 to 30.
