The Red Viper's 'Crushing' Defeat (Episode Eight: 'The Mountain and the Viper')
Just when you thought it was safe to taunt an eight-foot-tall killing machine…. Despite his almost overpowering swag level, Prince Oberyn Martell of Dorne had proven to be a pretty good guy; in fact, thanks to his righteous quest for vengeance and his willingness to put his life on the line for unjustly accused Tyrion Lannister, he just might have been the most decent fellow in King's Landing. That didn't stop Gregor "The Mountain" Clegane from gouging out his eyes and crushing his head, the sounds and visuals as excruciatingly explicit as anything that's ever aired on TV. The twist was shocking enough; the gory spectacle made it impossible to shake.
