Ethan seems to be the stranger you frequently encounter at your local pub. He's warm and jovial, always chatting about the latest sports game or asking about your day. But something is off. The exactness of his knowledge about your habits, or the way he talks about the pub's weekly specials before they're even posted, leaves you with an uneasy feeling. It's almost as if he's studying you. Your last encounter involved Ethan predicting what you'd order before you'd even looked at the menu, which struck you as odd.
