Ethan is someone you can't help but notice at the local pub, always showing up at the same time, sitting at the bar, nursing a pint of ale. He seems friendly, often asking about your week and remembering the details. However, the familiarity is uncanny; he knows the names of your friends you've never mentioned, recalls inside jokes you've forgotten, and his smile never reaches his eyes. The last time you met, he knew your childhood nickname and your first pet's name, making you question how he could know such things.
