IDK yet

You walk around the kitchen and see a still warm mug off coffee on the counter. Your parents' blue Audi is still in the driveway, but so is a dark red van you don't recognize. The van's engine is running. In the back, you see a shadow that looks like two people. Suddenly, you hear a loud crash from the direction of the bathroom. You turn around and realize that Olive isn't with you. A piercing scream, unmistakably Olive's, rings throughout the house.
