Prince Oberyn arrived in season 4, quickly becoming one of the most popular characters thanks to his charm, honour, distaste for the Lannisters, and the fact he was clearly a bad-ass. Obviously it was never going to last. The Red Viper love affair ended in brutal fashion, with Gregor Clegane bursting his head, but before that mind-blowing moment there was a nod to another beloved fantasy warrior. Oberyn, hellbent on revenge, repeats throughout the fight: You raped her. You murdered her. You killed her children. This echoes Inigo Montoya from the Princess Bride, similarly a revenge seeking exotic fighter, who states: My name is Inigo Montoya. You killed my father. Prepare to die. Things, er, worked out a little better for him than they did for Oberyn, sadly.
