S3E3 The Bitterest Pill

Title: The Harshest Dose Plot: A young boy who endures mistreatment from his parents finds an unexpected ally in his quirky uncle, who persuades them to invest in his latest creation—a pill designed to enhance intelligence and memory. Tragically, the uncle has a stroke and passes away, but not before the boy consumes the sole prototype. Empowered by the pill, he turns the tables on his parents, forcing them to experience the same neglect he once faced.
