- Paranoia Fuel: The idea that somebody could be obsessed with you to the point of breaking into your house to watch you sleep, writing creepy fan fiction about you and relentlessly stalking you for years before you even meet them. To make matters worse, when you finally do meet them, you discover you can't get away from them, no matter how hard you try. This is what Gumball and Darwin go through in this episode. While it seems exaggerated, there really are people who have done the sort of things that Sarah does in this episode in real life.
