Season 14, Episode 7: "Who Lives, Who Dies, Who Tells Your Story"
This episode is a love letter for anyone who has religiously tuned into Grey's all these years. Meredith's in the run for a Harper Avery (now the Catherine Fox Award), but she decides to kick it in Seattle to focus on a patient. The episode is full of little Easter eggs, such as doppelgänger Izzie, George, and Cristina. It's not just a fun and fluffy installment, though — it lovingly pays respects to Meredith's character growth over the years. We dare you not to cry over Jackson's lovely little speech for her.
