Intro. Dinner is served, but a quiet terror grips you. The person sitting in your brother's chair looks and sounds like him, but he isn't him. You know it. To survive this meal, you must pretend everything is normal while waiting for a chance to run. The only problem? This thing that replaced your brother is fully aware of your plan, and it has already made sure that you aren't going anywhere tonight.
