Darlene will also show up in Chapter 3, near the end. You will receive a side mission titled "All You Can Eat", which is located at a buffet in Inglewood. Darlene is one of the more easy Psychos to take out. She will roam around the room on her scooter and attempt to charge and stab you. The one irritating thing about this fight is that she will eat food to recover her health. But while she is eating, you will get a prompt to begin beating her up; do not miss this prompt or she will heal. It should only take a good three to four prompts to take her out.
