Anyone getting into Game of Thrones soon learns that this isnt a show where your favorite characters never die. This isnt a show where the good guys always succeed and the bad guys always fail. No, in this show, no one is safe. Whether youre good or bad, young or old, courageous or cowardly, your chances of dying are the same as everyone else's, and in the world created by George R.R. Martin, those chances are quite high. We lost one of the good ones in The Mountain and the Viper, Oberyn Martell was introduced in the season premiere Two Swords, and the audience was quite taken with him. The foreign prince from Dorne, he was a smooth talker who had a way with the ladies and men, and was able to see through the lies of Kings Landing. However, his primary goal was one of justice: to seek revenge against those who were behind the murder of his sister Elia and her children. This is what prompted him to act as Tyrions champion in the trial by combat, since he would be facing Ser Gregor Clegane, the man who committed the murder. We may have been rooting for him, but that accomplishes nothing in this series. Though the battle was epic, Oberyn met a gruesome death at the hands of The Mountain, securing Tyrion an execution for the murder of Joffrey. Of course, there were other events in this episode, though they were not nearly as exciting. The wildlings got closer to the Wall, a betrayal was revealed in Meereen, Ramsay received a special reward, and plenty more. So check out the seven things we learned in The Mountain and the Viper (aside from the fact that you should't watch the Oberyn vs. Gregor battle while eating). Remember, no book spoilers here. Only TV analysis.
