Season 12, episode 9: "The Sound of Silence"
Meredith Grey’s life is one long series of unfortunate events. Not long after losing her husband, Meredith is attacked by a patient in a fugue seizure state. Directed by the one and only Denzel Washington, this episode explores Meredith's perspective as a patient, one so terribly fragile and mangled that she can only frustratingly observe her surroundings after temporarily losing the ability to hear and speak. Creatively conjured and executed, the episode is literally half silent. As she heals, Mer observes the drama that behooves her friends. We get a tender moment at the end of the episode when Meredith bravely forgives the man who hurt her so badly. Side note: Richard serenading a cantankerous and healing Meredith with "My Girl" alone makes this episode a worthwhile watch.
