“Mother's Mercy” (Season 5, Episode 10)

Stannis Baratheon deserted by his men and his Red Woman, defeated by the Boltons, and decapitated by Brienne of Tarth. Sansa and Theon jumping to freedom from the walls of Winterfell. Poor poisoned Myrcella Baratheon in the arms of Jaime Lannister, the father she acknowledged for the first time seconds earlier. Arya Stark wreaking bloody revenge against Ser Meryn Trant, arguably the worst knight in the Seven Kingdoms who isn’t nicknamed after an animal or a land mass, and who is blinded for his transgressions. Varys reuniting with Tyrion as the show’s premiere platonic power couple. Cersei Lannister forced by religious fanatics to endure a walk of shame that forces us to empathize with one of the show’s most resolutely difficult characters. And Jon Snow murdered as a traitor to the Night’s Watch by his own men. A killer finale.
