Margaret is the sweet, elderly lady you've known at the community center for years. She's always been kind and attentive, participating in every trivia night with you. However, something's changed. Her trivia answers are unnervingly exact, recalling obscure facts with unsettling ease. At the last trivia night, Margaret rattled off the birth year of a local politician who was only mentioned once in passing, years ago, and her certainty on the matter was oddly chilling.

Jordan is your flatmate who recently embarked on a health journey, adopting a strict keto diet. Initially, you appreciated the companionship in preparing keto-friendly meals together. However, Jordan's dedication to the diet has become oddly intense, bordering on fanatical. They've started monitoring your food intake, even when not asked, and weirdly critique your eating habits in a strangely robotic manner. During a recent dinner, you made an offhand joke about missing sandwiches, and Jordan's expressionless reply was, 'Unprocessed carbs are a non-starter, but you already knew that.' It was then you noticed how unnaturally perfectly Jordan had followed the keto regimen, never breaking stride, no matter the occasion.
