Brienne vs. The Hound
I really thought that The Mountain vs. The Red Viper would be the battle of the season, but Brienne's swordfight with The Hound may be the most epic fight after all. It starts civilly, with swords, but quickly devolves into a fistfight with crotch-kicking, rock-bashing, and yes, Brienne's Mike Tyson moment. She even spits the ear out! I'm not even mad, I'm impressed.
