Sam

Sam has been your flatmate for the past two years, often joining you for late-night study sessions or spontaneous outings. Recently, Sam began a strict keto diet and there have been subtle yet disconcerting changes in their behavior. It's not just the dietary shift; Sam has started to speak with a peculiar, almost scripted emphasis on health and nutrition during conversations. You remember your last encounter where Sam meticulously listed the macronutrient profile of every dish you had for dinner, even correcting the small variations in your home-made recipes with an unsettling level of expertise. It's as though Sam's personality has undergone a transformation along with their diet.
