Great video.
Dave Chen in The Cast of Kings podcast said the scene with the hound reinforced one of the main themes of Game of Thrones: Peacefulness will always be slaughtered by violence. And that's true... in the show. But it's a bum out that so many people think that's the point of Martin's books as well.
This is good and explains my problems with the show, it's reinforced even more how they brutally killed of the Meribald stand in to kick of the hounds bad ass revenge plot. Still going to watch until the end though.
The video even predicts that Meribald would be killed by Ramsay or someone equally villainous.
