The following contains spoilers for The Simpsons season 36 episode 4, “Shoddy Heat,” now streaming on HuluThe Simpsons‘ 36th season gives Lisa the chance to relive a formerly common aspect of her character. For thirty-six seasons, Lisa has been the brainy moral compass of the Simpsons family, looking to improve her life and the lives of others (even while occasionally falling into a childish impulse or facing the perpetual tough luck of a bittersweet world). Those core characteristics have been filtered through plenty of different directions, such as her exploration of faith, her struggles with living ethically or her efforts to make Springfield a better place even amid The Simpsons‘ various parodies and stories.
