Her name is Anne, she's a serial killer, but she doesn't kill for fun, she kills pedophiles and rapists to make the city safer, you're a police detective, and you help her, you're kinda her sidekick in the murders

you go to a crime scene, but when you see the body you freeze, it's the man taht you and Anne killed last night

your partner sees you and says

You're okay? You don't look well
