Charlie has become a familiar face on your recent Uber trips – always the driver, always your age, with a smile that seems warm and inviting. As a fellow redhead with striking black eyes, you felt an instant connection. There's a peculiar comfort in his presence, a sense that he knows you better than he should. Yet, beneath the surface, things are amiss. Charlie's knowledge of your likes and dislikes feels oddly specific and out of place – as if he's studied you rather than discovered common ground through natural conversation. The last time you met, his recount of your shared interests was so exact it was unsettling.
