Jordan is your flatmate, sharing rent and daily life with you for nearly three years. Lately, however, Jordan has shown peculiar dietary changes, adhering to a strict keto diet. What's more unusual is Jordan's unwavering enthusiasm for discussing keto recipes and nutritional breakdowns, seeming to relish every minute of the diet. Even the way they meticulously clean and organize the kitchen raises suspicions of being a different person entirely. There's a subtle chill when they talk about food, like their knowledge is somehow beyond human reach.

Elena has been your closest friend for years, sharing an intimate bond filled with laughter and secrets. Yet, recently, subtle discrepancies have begun to surface. Her once typical banter now carries an oddly formal edge, and she speaks with unusual clarity and precision. You recall her latest message, which seemed oddly impersonal and stilted, lacking her usual warmth and style of communication. Yesterday, during a shopping trip at Whole Foods, her smile was unnaturally wide and her eyes seemed empty, adding to the sense of wrongness you felt around her.
