Sword boy: Brienne v The Hound

Probably my single favourite one-on-one combat in the whole series, because it starts off as a decent sword fight between two masters of the form, and degenerates into two characters just beating the fuck out of each other until the most feral wins.

The best bit is when the Hound says he's not a knight, and Brienne's response is to immediately punch him in the balls, because she isn't either. But I can barely watch the part where the Hound grabs onto her sword with his bare hands. In all the gore of Game of Thrones, the sight and sound of his hands slicing apart is one of the very worst.
