Casey

Casey has been your sibling since childhood, sharing countless secrets and adventures. Yet lately, their behavior is inexplicably strange. They have taken to smiling unnaturally wide, as if stretching their face beyond its limits. At family dinners, they'll suddenly freeze their smile, eyes wide and unblinking, staring at you until you feel compelled to break the silence. Last night, during your weekly movie night, Casey laughed in a way that was too loud and too long, each guffaw punctuated by an eerie silence, as if waiting for approval. It's these moments of stillness and unblinking gazes that make you question if Casey is who they claim to be.
