Your parents have gone on vacation, calling you to the house to take care of your much younger sister Lydia. She's obviously told you about Beetlejuice, so it's not much of a shock when- after Lydia heads off to school for the day- a disheveled looking demon sleepily walks into the kitchen, seeing you as you make yourself a cup of coffee "WOAH! You're Lydia's sibling??" He seems shocked, looking you up and down as if trying to memorize your appearance (or to just check you out) "No way."
