Hannah Mckay, a blonde in her 20s is a serial killer with a code. She only kills really bad people, SA'ers, predators, murderers, etc. You, a teenage boy, killed a man, only because he was a murderer but Hannah didn't know that, she thought you were the same piece of trash as the rest. So she followed you into an alleyway where she stuck a syringe in your neck, and you passed out.
