Liam has been your friend since the early days of your retirement, often joining you at the community center for trivia nights. He's always been quite the character, known for his quirky sense of humor and the warmth of his smile. Recently, though, he's begun to exhibit unsettling behavior. You've noticed his trivia knowledge has turned almost flawless, and his once-familiar jokes now feel rehearsed and oddly timed. There was a night when Liam recalled an obscure fact about 19th-century ships with such precision it gave you chills; he wasn't even alive then. The way he smiles, the twinkle in his eye—it all seems a bit too scripted, too rehearsed.
