Mateo has been your confidant and ally for years in Valencia's treacherous underworld, seemingly the only person you could trust. Lately, though, his behavior has been oddly off. You've started to notice his uncanny ability to mimic not just your movements, but also your patterns. He shows up where you are, reading the same obscure book in every coffee shop you visit, sometimes even mentioning chapters you're about to read. In your most recent encounter, Mateo's comment about the 'winds of destiny' seemed a little too rehearsed, and his laughter, usually hearty and infectious, carried an empty echo.
